I. Self-Regulatory Organization's Statement of the Terms of Substance 
of the Proposed Rule Change

    The Exchange proposes to list and trade shares of the following 
under NYSE Arca Rule 8.201-E: Grayscale Cardano Trust (ADA) (the 
``Trust''). This Amendment No. 2 to SR-NYSEARCA-2025-12 replaces SR-
NYSEARCA-2025-12 and Amendment No. 1 thereto as originally filed and 
supersedes such filings in their entirety. The proposed rule change is 
available on the Exchange's website at www.nyse.com, at the principal 
office of the Exchange, and at the Commission's Public Reference Room.

II. Self-Regulatory Organization's Statement of the Purpose of, and 
Statutory Basis for, the Proposed Rule Change

    In its filing with the Commission, the self-regulatory organization 
included statements concerning the purpose of, and basis for, the 
proposed rule change and discussed any comments it received on the 
proposed rule change. The text of those statements may be examined at 
the places specified in Item IV below. The Exchange has prepared 
summaries, set forth in sections A, B, and C below, of the most 
significant parts of such statements.

A. Self-Regulatory Organization's Statement of the Purpose of, and the 
Statutory Basis for, the Proposed Rule Change

1. Purpose
    Under NYSE Arca Rule 8.201-E, the Exchange may propose to list and/
or trade pursuant to unlisted trading privileges ``Commodity-Based 
Trust Shares.'' \5\ The Exchange proposes to list and trade shares 
(``Shares'') \6\ of the Trust pursuant to NYSE Arca Rule 8.201-E.
---------------------------------------------------------------------------

    \5\ Commodity-Based Trust Shares are securities issued by a 
trust that represent investors' discrete identifiable and undivided 
beneficial ownership interest in the commodities deposited into the 
Trust.
    \6\ The Shares are expected to be listed under the ticker symbol 
``GADA.''
---------------------------------------------------------------------------

    The sponsors of the Trust are Grayscale Operating, LLC and 
Grayscale Investments Sponsors, LLC (each, a ``Sponsor'' and, 
collectively, the ``Sponsors''),\7\ each a Delaware limited liability 
company. The Sponsors are indirect wholly owned subsidiaries of Digital 
Currency Group, Inc. (``Digital Currency Group''). The trustee for the 
Trust is Delaware Trust Company (``Trustee''). The custodian for the 
Trust is Coinbase Custody Trust Company, LLC (``Custodian''). The 
administrator and transfer agent of the Trust is expected to be BNY 
Mellon Asset Servicing, a division of The Bank of New York Mellon (the 
``Transfer Agent''). The distribution and marketing agent for the Trust 
is expected to be Foreside Fund Services, LLC (the ``Marketing 
Agent''). The index provider

[[Page 10965]]

for the Trust is CoinDesk Indices, Inc. (the ``Index Provider'').
---------------------------------------------------------------------------

    \7\ As of May 3, 2025, Grayscale Operating, LLC will cease to 
act as Sponsor of the Trust and Grayscale Investment Sponsors, LLC 
will be sole Sponsor of the Trust.
---------------------------------------------------------------------------

    The Trust is a Delaware statutory trust, formed on January 26, 
2018, that operates pursuant to a trust agreement between the Sponsor 
and the Trustee (``Trust Agreement''). The Trust has no fixed 
termination date.
Operation of the Trust
    According to the prospectus the Trust intends to file (the 
``Prospectus''), the Trust's assets consist solely of Cardano 
(``ADA'').\8\
---------------------------------------------------------------------------

    \8\ The Trust may from time to time come into possession of 
Incidental Rights and/or IR Virtual Currency by virtue of its 
ownership of ADA, generally through a fork in the Cardano 
Blockchain, an airdrop offered to holders of ADA or other similar 
event. ``Incidental Rights'' are rights to acquire, or otherwise 
establish dominion and control over, any virtual currency or other 
asset or right, which rights are incident to the Trust's ownership 
of ADA and arise without any action of the Trust, or of the Sponsor 
or Trustee on behalf of the Trust. ``IR Virtual Currency'' is any 
virtual currency tokens, or other asset or right, acquired by the 
Trust through the exercise (subject to the applicable provisions of 
the Trust Agreement) of any Incidental Right. Although the Trust is 
permitted to take certain actions with respect to Incidental Rights 
and IR Virtual Currency in accordance with its Trust Agreement, at 
this time the Trust will prospectively irrevocably abandon any 
Incidental Rights and IR Virtual Currency. In the event the Trust 
seeks to change this position, the Exchange would file a subsequent 
proposed rule change with the Commission.
---------------------------------------------------------------------------

    Each Share represents a proportional interest, based on the total 
number of Shares outstanding, in the Trust's assets as determined by 
reference to the Index Price,\9\ less the Trust's expenses and other 
liabilities (which include accrued but unpaid fees and expenses). The 
Sponsors expect that the market price of the Shares will fluctuate over 
time in response to the market prices of ADA. In addition, because the 
Shares reflect the estimated accrued but unpaid expenses of the Trust, 
the number of ADA represented by a Share will gradually decrease over 
time as the Trust's ADA are used to pay the Trust's expenses.
---------------------------------------------------------------------------

    \9\ The ``Index Price'' means the U.S. dollar value of a ADA 
derived from the Digital Asset Trading Platforms (as defined below) 
that are reflected in the CoinDesk Cardano Price Index (ADX) (the 
``Index''), calculated at 4:00 p.m., New York time, on each business 
day. For purposes of the Trust Agreement, the term Cardano Index 
Price has the same meaning as the Index Price as defined herein.
---------------------------------------------------------------------------

    The activities of the Trust are limited to (i) issuing ``Baskets'' 
(as defined below) in exchange for ADA transferred to the Trust as 
consideration in connection with creations, (ii) transferring or 
selling ADA as necessary to cover the ``Sponsor's Fee'' \10\ and/or 
certain Trust expenses, (iii) transferring ADA in exchange for Baskets 
surrendered for redemption (subject to obtaining regulatory approval 
from the Commission and approval of the Sponsor), (iv) causing the 
Sponsor to sell ADA on the termination of the Trust, and (v) engaging 
in all administrative and security procedures necessary to accomplish 
such activities in accordance with the provisions of the Trust 
Agreement, the Custodian Agreement, the Index License Agreement, and 
the Participant Agreements (each as defined below).
---------------------------------------------------------------------------

    \10\ The Sponsor's Fee means a fee, payable in ADA, which 
accrues daily in U.S. dollars at an annual rate of currently 2.5%, 
but which will be lowered in connection with the Trust becoming an 
ETP, of the NAV Fee Basis Amount of the Trust as of 4:00 p.m., New 
York time, on each day, provided that for a day that is not a 
business day, the calculation of the Sponsor's Fee will be based on 
the NAV Fee Basis Amount from the most recent business day, reduced 
by the accrued and unpaid Sponsor's Fee for such most recent 
business day and for each day after such most recent business day 
and prior to the relevant calculation date. The ``NAV Fee Basis 
Amount'' is calculated in the manner set forth under ``Valuation of 
ADA and Determination of NAV'' below.
---------------------------------------------------------------------------

    The Trust will not be actively managed. It will not engage in any 
activities designed to obtain a profit from, or to ameliorate losses 
caused by, changes in the market prices of ADA.
    The Trust is not a registered investment company under the 
Investment Company Act and the Sponsors believe that the Trust is not 
required to register under the Investment Company Act.
Investment Objective
    According to the Prospectus, and as further described below, the 
Trust's investment objective is for the value of the Shares (based on 
ADA per Share) to reflect the value of the ADA held by the Trust, 
determined by reference to the Index Price, less the Trust's expenses 
and other liabilities. While an investment in the Shares is not a 
direct investment in ADA, the Shares are designed to provide investors 
with a cost-effective and convenient way to gain investment exposure to 
ADA. Generally speaking, a substantial direct investment in ADA may 
require expensive and sometimes complicated arrangements in connection 
with the acquisition, security and safekeeping of the ADA and may 
involve the payment of substantial fees to acquire such ADA from third-
party facilitators through cash payments of U.S. dollars. Because the 
value of the Shares is correlated with the value of ADA held by the 
Trust, it is important to understand the investment attributes of, and 
the market for, ADA.
    The Trust uses the Index Price to calculate its ``NAV,'' which is 
the aggregate value, expressed in U.S. dollars, of the Trust's assets 
(other than U.S. dollars or other fiat currency), less the U.S. dollar 
value of the Trust's expenses and other liabilities calculated in the 
manner set forth under ``Valuation of ADA and Determination of NAV.'' 
``NAV per Share'' is calculated by dividing NAV by the number of Shares 
then outstanding.
Valuation of ADA and Determination of NAV
    The following is a description of the material terms of the Trust 
Agreement as they relate to valuation of the Trust's ADA and the NAV 
calculations.
    On each business day at 4:00 p.m., New York time, or as soon 
thereafter as practicable (the ``Evaluation Time''), the Sponsor will 
evaluate the ADA held by the Trust and calculate and publish the NAV of 
the Trust. To calculate the NAV, the Sponsor will:
    1. Determine the Index Price as of such business day.
    2. Multiply the Index Price by the Trust's aggregate number of ADA 
owned by the Trust as of 4:00 p.m., New York time, on the immediately 
preceding day, less the aggregate number of ADA payable as the accrued 
and unpaid Sponsor's Fee as of 4:00 p.m., New York time, on the 
immediately preceding day.
    3. Add the U.S. dollar value of ADA, calculated using the Index 
Price, receivable under pending creation orders, if any, determined by 
multiplying the number of the Baskets represented by such creation 
orders by the Basket Amount and then multiplying such product by the 
Index Price.\11\
---------------------------------------------------------------------------

    \11\ ``Baskets'' and ``Basket Amount'' have the meanings set 
forth in ``Creation and Redemption of Shares'' below.
---------------------------------------------------------------------------

    4. Subtract the U.S. dollar amount of accrued and unpaid Additional 
Trust Expenses, if any.\12\
---------------------------------------------------------------------------

    \12\ A ``Digital Asset Market'' is a ``Brokered Market,'' 
``Dealer Market,'' ``Principal-to-Principal Market'' or ``Exchange 
Market,'' as each such term is defined in the Financial Accounting 
Standards Board Accounting Standards Codification Master Glossary. 
The ``Digital Asset Trading Platform Market'' is the global trading 
platform market for the trading of ADA, which consists of 
transactions on electronic Digital Asset Trading Platforms. A 
``Digital Asset Trading Platform'' is an electronic marketplace 
where trading participants may trade, buy and sell ADA based on bid-
ask trading. The largest Digital Asset Trading Platforms are online 
and typically trade on a 24-hour basis, publishing transaction price 
and volume data.
---------------------------------------------------------------------------

    5. Subtract the U.S. dollar value of the ADA, calculated using the 
Index Price, to be distributed under pending redemption orders, if any, 
determined by multiplying the number of Baskets to be redeemed 
represented by such redemption orders by the Basket Amount and then 
multiplying such product by the Index Price (the amount

[[Page 10966]]

derived from steps 1 through 5 above, the ``NAV Fee Basis Amount'').
    6. Subtract the U.S. dollar amount of the Sponsor's Fee that 
accrues for such business day, as calculated based on the NAV Fee Basis 
Amount for such business day.
    In the event that the Sponsor determines that the primary 
methodology used to determine the Index Price is not an appropriate 
basis for valuation of the Trust's ADA, the Sponsor will utilize the 
cascading set of rules as described in ``Determination of the Index 
Price When Index Price is Unavailable'' below.
ADA and the Cardano Network \13\
---------------------------------------------------------------------------

    \13\ The description of ADA and the Cardano Network in this 
section was provided by the Sponsors and is based on the Prospectus.
---------------------------------------------------------------------------

    According to the Prospectus, ADA is a digital asset that is created 
and transmitted through the operations of the peer-to-peer Cardano 
network, a decentralized network of computers that operates on 
cryptographic protocols. No single entity owns or operates the Cardano 
network, the infrastructure of which is collectively maintained by a 
decentralized user base. The Cardano network allows people to exchange 
tokens of value, called ADA, which are recorded on a public transaction 
ledger known as a blockchain. ADA can be used to pay for goods and 
services, including computational power on the Cardano network, or it 
can be converted to fiat currencies, such as the U.S. dollar, at rates 
determined on Digital Asset Exchanges or in individual end-user-to-end-
user transactions under a barter system.
    The Cardano network was designed to allow users to write and 
implement smart contracts--that is, general-purpose code that executes 
on every computer in the network and can instruct the transmission of 
information and value based on a sophisticated set of logical 
conditions. Using smart contracts, users can create markets, store 
registries of debts or promises, represent the ownership of property, 
move funds in accordance with conditional instructions and create 
digital assets other than ADA on the Cardano network. When operational, 
smart contract operations are executed on the Cardano blockchain in 
exchange for payment of ADA. Like the Ethereum network, the Cardano 
network is one of a number of projects intended to expand blockchain 
use beyond just a peer-to-peer money system.
    Cardano was founded by Charles Hoskinson, an early contributor of 
the Ethereum Network, as a proof-of-stake alternative to blockchains 
relying on proof-of-work. The proof-of-stake consensus mechanism is 
intended to provide lower energy consumption in the validation of the 
network and potentially faster transaction times. The Cardano 
Foundation, a Swiss non-profit organization that administered the 
original network launch and token distribution, contributes to the 
development of the Cardano network. The Cardano Foundation has 
contracted Input-Output Global (``IOHK''), a company founded by 
Hoskinson, to continue building and maintaining the Cardano network, as 
well as Emurgo Pte. Ltd. (``Emurgo''), a for-profit company responsible 
for building partnerships with developers of the Cardano Network. 
Additionally, twenty percent of Cardano transaction fees are currently 
allocated to the Cardano's treasury (the ``Cardano Treasury'') (with 
the rest of the fees being used for staking rewards). The Cardano 
Treasury allocates resources to develop the Cardano network and create 
new applications in the Cardano ecosystem.
    The Cardano Network is decentralized and does not require 
governmental authorities or financial institution intermediaries to 
create, transmit or determine the value of ADA. Rather, ADA is created 
and allocated by the Cardano Network protocol through a ``mining'' 
process. The value of ADA is determined by the supply of and demand for 
ADA on the Digital Asset Trading Platforms or in private end-user-to-
end-user transactions.
    Similar to the Ethereum Network, new ADA are created and rewarded 
to the validators of a block in the Cardano Blockchain for verifying 
transactions. The Cardano Blockchain is effectively a decentralized 
database that includes all blocks that have been validated, and it is 
updated to include new blocks as they are validated. Each ADA 
transaction is broadcast to the Cardano Network and, when included in a 
block, recorded in the Cardano Blockchain. As each new block records 
outstanding ADA transactions, and outstanding transactions are settled 
and validated through such recording, the Cardano Blockchain represents 
a complete, transparent and unbroken history of all transactions of the 
Cardano Network. Among other things, ADA is used to pay for transaction 
fees and computational services (i.e., smart contracts) on the Cardano 
Network; users of the Cardano Network pay for the computational power 
of the machines executing the requested operations with ADA. Requiring 
payment in ADA on the Cardano Network incentivizes developers to write 
quality applications and increases the efficiency of the Cardano 
Network while ensuring that the Cardano Network remains economically 
viable by compensating for contributed computational resources.
Smart Contracts and Development on the Cardano Network
    Smart contracts are programs that run on a blockchain that can 
execute automatically when certain conditions are met. Smart contracts 
facilitate the exchange of anything representative of value, such as 
money, information, property, or voting rights. Using smart contracts, 
users can send or receive digital assets, create markets, store 
registries of debts or promises, represent ownership of property or a 
company, move funds in accordance with conditional instructions and 
create new digital assets. Development on the Cardano Network involves 
building more complex tools on top of smart contracts, such as 
decentralized apps (``DApps''); organizations that are autonomous, 
known as decentralized autonomous organizations (``DAOs''); and 
entirely new decentralized networks. For example, a company that 
distributes charitable donations on behalf of users could hold donated 
funds in smart contracts that are paid to charities only if the charity 
satisfies certain pre-defined conditions.
    Moreover, like the Ethereum network, the Cardano Network can also 
be used as a platform for creating new digital assets and conducting 
their associated initial coin offerings. However, a majority of digital 
assets are built on the Ethereum network, with such assets representing 
a significant amount of the total market value of all digital assets.
    Like the Ethereum network, the Cardano Network is also used for 
decentralized finance (``DeFi'') or open finance platforms, which seek 
to democratize access to financial services, such as borrowing, 
lending, custody, trading, derivatives and insurance, by removing 
third-party intermediaries. DeFi can allow users to lend and earn 
interest on their digital assets, exchange one digital asset for 
another and create derivative digital assets such as stablecoins, which 
are digital assets pegged to a reserve asset such as fiat currency. As 
of the date hereof, approximately $384 million worth of digital assets 
were locked up as collateral on DeFi platforms on the Cardano 
Network.\14\

---------------------------------------------------------------------------

Overview of the Cardano Network's Operations
    In order to own, transfer or use ADA directly on the Cardano 
Network (as opposed to through an intermediary, such as a custodian), a 
person generally must have internet access to connect to the Cardano 
Network. ADA transactions may be made directly between end-users 
without the need for a third-party intermediary. To prevent the 
possibility of double-spending ADA, a user must notify the Cardano 
Network of the transaction by broadcasting the transaction data to its 
network peers. The Cardano Network provides confirmation against 
double-spending by memorializing every transaction in the Cardano 
Blockchain, which is publicly accessible and transparent. This 
memorialization and verification against double-spending is 
accomplished through the Cardano Network validating process, which adds 
``blocks'' of data, including recent transaction information, to the 
Cardano Blockchain.
Summary of a ADA Transaction
    Prior to engaging in ADA transactions directly on the Cardano 
Network, a user generally must first install on its computer or mobile 
device a Cardano Network software program that will allow the user to 
generate a private and public key pair associated with a ADA address. 
Each Cardano Network address, or wallet, is associated with a unique 
``public key'' and ``private key'' pair. To receive ADA, the ADA 
recipient must provide its public key to the party initiating the 
transfer. This activity is analogous to a recipient for a transaction 
in U.S. dollars providing a routing address in wire instructions to the 
payor so that cash may be wired to the recipient's account. The payor 
approves the transfer to the address provided by the recipient by 
``signing'' a transaction that consists of the recipient's public key 
with the private key of the address from where the payor is 
transferring the ADA. The recipient, however, does not make public or 
provide to the sender its related private key.
    Neither the recipient nor the sender reveals their private keys in 
a transaction, because the private key authorizes transfer of the funds 
in that address to other users. Therefore, if a user loses his or her 
private key, the user may permanently lose access to the ADA contained 
in the associated address. Likewise, ADA is irretrievably lost if the 
private key associated with them is deleted and no backup has been 
made. When sending ADA, a user's Cardano Network software program must 
validate the transaction with the associated private key. In addition, 
since every computation on the Cardano Network requires processing 
power, there is a transaction fee involved with the transfer that is 
paid by the payor. The resulting digitally validated transaction is 
sent by the user's Cardano Network software program to the Cardano 
Network validators to allow transaction confirmation.
    Cardano Network validators record and confirm transactions when 
they validate and add blocks of information to the Cardano Blockchain. 
In proof-of-stake, validators compete to be randomly selected to 
validate transactions. When a validator is selected to validate a 
block, it creates that block, which includes data relating to (i) the 
verification of newly submitted and accepted transactions and (ii) a 
reference to the prior block in the Cardano Blockchain to which the new 
block is being added. The validator becomes aware of outstanding, 
unrecorded transactions through the data packet transmission and 
distribution discussed above.
    Upon the addition of a block of ADA transactions, the Cardano 
Network software program of both the spending party and the receiving 
party will show confirmation of the transaction on the Cardano 
Blockchain and reflect an adjustment to the ADA balance in each party's 
Cardano Network public key, completing the ADA transaction. Once a 
transaction is confirmed on the Cardano Blockchain, it is irreversible.
    Some ADA transactions are conducted ``off-blockchain'' and are 
therefore not recorded in the Cardano Blockchain. These ``off-
blockchain transactions'' involve the transfer of control over, or 
ownership of, a specific digital wallet holding ADA or the reallocation 
of ownership of certain ADA in a pooled-ownership digital wallet, such 
as a digital wallet owned by a Digital Asset Trading Platform. In 
contrast to on-blockchain transactions, which are publicly recorded on 
the Cardano Blockchain, information and data regarding off-blockchain 
transactions are generally not publicly available. Therefore, off-
blockchain transactions are not truly ADA transactions in that they do 
not involve the transfer of transaction data on the Cardano Network and 
do not reflect a movement of ADA between addresses recorded in the 
Cardano Blockchain. For these reasons, off-blockchain transactions are 
subject to risks as any such transfer of ADA ownership is not protected 
by the protocol behind the Cardano Network or recorded in, and 
validated through, the blockchain mechanism.

Creation of ADA
Initial Creation of ADA
    Unlike other digital assets such as Bitcoin, which are solely 
created through a progressive mining process, 31.11 million ADA were 
created in connection with the launch of the Cardano Network in a 
series of public token sales that occurred between September 2015 and 
January 2017 to non-U.S. citizens. The initial 31.11 million ADA were 
distributed as follows:
     Tranche 1: 1,255,160,024 ADA sold, raising $2.66M (9.08K 
BTC).
     Tranche 2: 7,729,842,852 ADA sold, raising $16.49M (40.20K 
BTC).
     Tranche 3: 5,923,771,020 ADA sold, raising $14.32M (24.28K 
BTC).
     Tranche 3.5: 721,948,412 ADA sold, raising $19.36M (32.82K 
BTC).
     Tranche 4: 10,296,348,230 ADA sold, raising $26.36M 
(32.82K BTC).
    The remaining 5,185,414,108 ADA were received by the three legal 
entities that govern the Cardano network as follows:
     648,176,761 ADA to the Cardano Foundation;
     2,074,165,644 ADA to Emurgo;
     2,463,071,701 ADA to IOHK, which voluntarily adopted the 
following vesting schedule:

    Neither the Cardano Foundation nor Emurgo adopted a vesting 
schedule.
    In total, the Cardano Foundation, Emurgo and IOHK received 16.67% 
of the initial ADA distributed, and the public received 83.33% of the 
initial ADA distributed.
    Following these distributions, the remaining 13.89 billion ADA 
tokens are scheduled to be issued over time, in the form of staking 
rewards.
Proof-of-Stake Process
    Unlike proof-of-work, in which miners expend computational 
resources to compete to validate transactions and are rewarded coins in 
proportion to the amount of computational resources expended, in proof-
of-stake, miners (sometimes called validators) risk or ``stake'' coins 
to compete to be randomly selected to validate transactions and are 
rewarded coins in proportion to the amount of coins staked. Any 
malicious activity, such as validating multiple blocks, disagreeing 
with the eventual consensus, or otherwise violating protocol rules, 
results in the forfeiture or ``slashing'' of a portion of the staked 
coins. Proof-of-stake is viewed as more energy efficient and scalable 
than proof-of-work and is sometimes referred to as ``virtual mining.'' 
As of December 31, 2024, every 12 seconds, approximately, a new block 
is added to the Cardano Blockchain with the latest transactions 
processed by the network, and the validator that generated this block 
is awarded ADA.
Limits on ADA Supply
    The Cardano Network is structured to allow a maximum of 45 billion 
ADA to be created, which are mined over time with the creation of each 
new block. The supply of new ADA is mathematically controlled so that 
the number of ADA grows at a limited rate pursuant to a pre-set 
schedule. This deliberately controlled rate of ADA creation means that 
the number of ADA in existence will increase at a controlled rate until 
the number of ADA in existence reaches 45 billion ADA.
    As of the date hereof, approximately 35 billion ADA were 
outstanding, which are scheduled to be issued over time, in the form of 
staking rewards.
Modifications to the ADA Protocol
    Historically, the Cardano Network's development has historically 
been overseen by a core group of developers from the Cardano 
Foundation, IOHK and Emmurgo. The core developers are able to access, 
and can alter, the Cardano Network source code and, as a result, they 
are responsible for quasi-official releases of updates and other 
changes to the Cardano Network's source code.
    The Cardano network's development has been taking place in five 
phases. The first phase, known as Byron, began in 2015 and set the 
foundation of the Cardano Network for transitions in connection with 
the initial distribution and staking pools. The second phase, known as 
Shelley, began in 2019 introduced decentralization and saw the 
transition from staking pools being managed by IOHK and Emurgo to being 
community-owned. The third phase, known as Gougen, began in 2021 and 
introduced smart contract capabilities, enabling developers to build 
dApps and users to create new digital assets on the Cardano Network. 
The fourth phase, known as Basho, began in 2022 and seeks to improve 
scalability and interoperability of the Cardano Network through the 
introduction of sidechains. The fifth and final phase, known as 
Voltaire, will transfer governance of the Cardano Network to the 
community of ADA holders. Specifically, Voltaire is expected to 
introduce a formal process for ADA holders to propose and vote on 
``Cardano Improvement Proposals.'' Additionally, Voltaire phase is 
expected to provide more formal voting rights for ADA holders with 
respect to distributions of the Cardano Treasury. The release of 
updates to the Cardano Network's source code does not guarantee that 
the updates will be automatically adopted. Users and validators must 
accept any changes made to the Cardano source code by downloading the 
proposed modification of the Cardano Network's source code. A 
modification of the Cardano Network's source code is effective only 
with respect to the Cardano users and validators that download it. If a 
modification is accepted by only a percentage of users and validators, 
a division in the Cardano Network will occur such that one network will 
run the pre-modification source code and the other network will run the 
modified source code. Such a division is known as a ``fork.'' 
Consequently, as a practical matter, a modification to the source code 
becomes part of the Cardano Network only if accepted by participants 
collectively having most of the processing power on the Cardano 
Network.
Custody of the Trust's ADA
    Digital assets and digital asset transactions are recorded and 
validated on blockchains, the public transaction ledgers of a digital 
asset network. Each digital asset blockchain serves as a record of 
ownership for all of the units of such digital asset, even in the case 
of certain privacy-preserving digital assets, where the transactions 
themselves are not publicly viewable. All digital assets recorded on a 
blockchain are associated with a public blockchain address, also 
referred to as a digital wallet. Digital assets held at a particular 
public blockchain address may be accessed and transferred using a 
corresponding private key.
Key Generation
    Public addresses and their corresponding private keys are generated 
by the Custodian in secret key generation ceremonies at secure 
locations inside faraday cages, which are enclosures used to block 
electromagnetic fields and thus mitigate against attacks. The Custodian 
uses quantum random number generators to generate the public and 
private key pairs.
    Once generated, private keys are encrypted, separated into 
``shards,'' and then further encrypted. After the key generation 
ceremony, all materials used to generate private keys, including

[[Page 10969]]

computers, are destroyed. All key generation ceremonies are performed 
offline. No party other than the Custodian (including the Trust itself) 
has access to the private key shards of the Trust.
Key Storage
    Private key shards are distributed geographically in secure vaults 
around the world, including in the United States. The locations of the 
secure vaults may change regularly and are kept confidential by the 
Custodian for security purposes.
    The ``Digital Asset Account'' is a segregated custody account 
controlled and secured by the Custodian to store private keys, which 
allows for the transfer of ownership or control of the Trust's ADA on 
the Trust's behalf. The Digital Asset Account uses offline storage, or 
``cold,'' mechanisms to secure the Trust's private keys. The term cold 
storage refers to a safeguarding method by which the private keys 
corresponding to digital assets are disconnected and/or deleted 
entirely from the internet. Cold storage of private keys may involve 
keeping such keys on a non-networked (or ``air-gapped'') computer or 
electronic device or storing the private keys on a storage device (for 
example, a USB thumb drive) or printed medium (for example, papyrus, 
paper, or a metallic object). A digital wallet may receive deposits of 
digital assets but may not send digital assets without use of the 
digital assets' corresponding private keys. In order to send digital 
assets from a digital wallet in which the private keys are kept in cold 
storage, either the private keys must be retrieved from cold storage 
and entered into an online, or ``hot,'' digital asset software program 
to sign the transaction, or the unsigned transaction must be 
transferred to the cold server in which the private keys are held for 
signature by the private keys and then transferred back to the online 
digital asset software program. At that point, the user of the digital 
wallet can transfer its digital assets.
Security Procedures
    The Custodian is the custodian of the Trust's private keys (which, 
as noted above, facilitate the transfer of ownership or control of the 
Trust's ADA) in accordance with the terms and provisions of the 
custodian agreement by and between the Custodian, the Sponsor and the 
Trust (the ``Custodian Agreement''). Transfers from the Digital Asset 
Account require certain security procedures, including, but not limited 
to, multiple encrypted private key shards, usernames, passwords and 2-
step verification. Multiple private key shards held by the Custodian 
must be combined to reconstitute the private key to sign any 
transaction in order to transfer the Trust's assets. Private key shards 
are distributed geographically in secure vaults around the world, 
including in the United States.
    As a result, if any one secure vault is ever compromised, this 
event will have no impact on the ability of the Trust to access its 
assets, other than a possible delay in operations, while one or more of 
the other secure vaults is used instead. These security procedures are 
intended to remove single points of failure in the protection of the 
Trust's assets.
    Transfers of ADA to the Digital Asset Account will be available to 
the Trust once processed on the Blockchain.
    Subject to obtaining regulatory approval to operate a redemption 
program and authorization of the Sponsor, the process of accessing and 
withdrawing ADA from the Trust to redeem a Basket will follow the same 
general procedure as transferring ADA to the Trust to create a Basket, 
only in reverse.
    The Sponsor will maintain ownership and control of the Trust's ADA 
in a manner consistent with good delivery requirements for spot 
commodity transactions.
ADA Value
Digital Asset Trading Platform Valuation
    The value of ADA is determined by the value that various market 
participants place on ADA through their transactions. The most common 
means of determining the value of a ADA is by surveying one or more 
Digital Asset Trading Platforms where ADA is traded publicly and 
transparently (e.g., Bitfinex, Coinbase, Crypto.com, and Kraken).
Digital Asset Trading Platform Public Market Data
    On each online Digital Asset Trading Platform, ADA is traded with 
publicly disclosed valuations for each executed trade, measured by one 
or more fiat currencies such as the U.S. dollar or euro or by the 
widely used cryptocurrency Bitcoin. Over-the-counter dealers or market 
makers do not typically disclose their trade data.
    As of December 31, 2024, the Digital Asset Trading Platforms 
included in the Index were Coinbase, Crypto.com, Bitfinex, and Kraken. 
As further described below, the Sponsors and the Trust reasonably 
believe each of these Digital Asset Trading Platforms are in material 
compliance with applicable U.S. federal and state licensing 
requirements (except for Bitfinex as detailed below) and maintain 
practices and policies designed to comply with anti-money laundering 
(``AML'') and know-your-customer (``KYC'') regulations.
    Coinbase: A U.S.-based trading platform registered as a money 
services business (``MSB'') with the Financial Crimes Enforcement 
Network (``FinCEN'') and licensed as a virtual currency business under 
the New York State Department of Financial Services (``NYDFS'') 
BitLicense as well as a money transmitter in various U.S. states.
    Crypto.com: A Singapore-based trading platform registered as an MSB 
with FinCEN and licensed as a money transmitter in various U.S. states. 
Crypto.com does not hold a BitLicense.
    Bitfinex: A British Virgin Islands based trading platform. Bitfinex 
does not hold any licenses or registrations in the U.S. and is not 
available to U.S. based customers. Bitfinex is categorized by the Index 
Provider as a ``Category 2'' trading platform which meets the Inclusion 
Criteria outlined below but is non-U.S. licensed.
    Kraken: A U.S.-based trading platform registered as an MSB with 
FinCEN and licensed as a money transmitter in various U.S. states. 
Kraken does not hold a BitLicense.
    Currently, there are several Digital Asset Trading Platforms 
operating worldwide and online Digital Asset Trading Platforms 
represent a substantial percentage of ADA buying and selling activity 
and provide the most data with respect to prevailing valuations of ADA. 
These trading platforms include established trading platforms such as 
trading platforms included in the Index which provide a number of 
options for buying and selling ADA. The below table reflects the 
trading volume in ADA and market share of the ADA-U.S. dollar trading 
pairs of each of the Digital Asset Trading Platforms included in the 
Index as of December 31, 2024, (collectively, ``Constituent Trading 
Platforms'') using data since January 1, 2024:

\1\ Effective October 28, 2024, the Index Provider added Bitfinex to the
  Index due to the trading platform meeting the Index Provider's minimum
  liquidity requirement, and did not remove any Constituent Trading
  Platforms as part of its scheduled quarterly review.
\2\ Market share is calculated using trading volume (in ADA) for certain
  Digital Asset Trading Platforms including, Coinbase, Crypto.com,
  Bitfinex and Kraken, as well as certain other large U.S.-dollar
  denominated Digital Asset Trading Platforms that were not included in
  the Index as of December 31, 2024, including Bitstamp.

Forms of Attack Against the Cardano Network
    All networked systems are vulnerable to various kinds of attacks. 
As with any computer network, the Cardano Network contains certain 
flaws. For example, the Cardano Network is currently vulnerable to a 
``51% attack'' where, if a party or group were to gain control of more 
than 50% of the staked ADA, a malicious actor would be able to gain 
full control of the network and the ability to manipulate the Cardano 
Blockchain. As of the date of filing, the top three largest staking 
pools controlled approximately 1.3% of the ADA staked on the Cardano 
Network.
    In addition, many digital asset networks have been subjected to a 
number of denial of service attacks, which has led to temporary delays 
in block creation and in the transfer of ADA. Any similar attacks on 
the Cardano Network that impact the ability to transfer ADA could have 
a material adverse effect on the price of ADA and the value of the 
Shares.
The Index and the Index Price
    The Index is a U.S. dollar-denominated composite reference rate for 
the price of ADA. The Index is designed to (1) mitigate the effects of 
fraud, manipulation and other anomalous trading activity from impacting 
the ADA reference rate, (2) provide a real-time, volume-weighted fair 
value of ADA and (3) appropriately handle and adjust for non-market 
related events.
    The Index Price is determined by the Index Provider through a 
process in which trade data is cleansed and compiled in such a manner 
as to algorithmically reduce the impact of anomalistic or manipulative 
trading. This is accomplished by adjusting the weight of each data 
input based on price deviation relative to the observable set, as well 
as recent and long-term trading volume at each venue relative to the 
observable set.
    The value of the Index is calculated and disseminated on a 24-hour 
basis and will be available on a continuous basis.
Constituent Trading Platform Selection
    According to the Prospectus, the Digital Asset Trading Platforms 
that are included in the Index are selected by the Index Provider 
utilizing a methodology that is guided by the International 
Organization of Securities Commissions (``IOSCO'') principles for 
financial benchmarks. For a trading platform to become a Constituent 
Trading Platform, it must satisfy each of the criteria listed below 
(the ``Inclusion Criteria''):
     Sufficient USD or USDC liquidity relative to the size of 
the listed assets;
     No evidence in the past 12 months of trading restrictions 
on individuals or entities that would otherwise meet the trading 
platform's eligibility requirements to trade;
     No evidence in the past 12 months of undisclosed 
restrictions on deposits or withdrawals from user accounts;
     Real-time price discovery;
     Limited or no capital controls; \19\
---------------------------------------------------------------------------

    \19\ ``Capital controls'' in this context means governmental 
sanctions that would limit the movement of capital into, or out of, 
the jurisdiction in which such Digital Asset Trading Platforms 
operate.
---------------------------------------------------------------------------

     Transparent ownership including a publicly-known ownership 
entity;
     Publicly available language and policies addressing legal 
and regulatory compliance in the U.S., including KYC, AML and other 
policies designed to comply with relevant regulations that might apply 
to it;
     Be a trading platform that is licensed and able to service 
investors in one or more of the following jurisdictions:
    [cir] United States,
    [cir] United Kingdom,
    [cir] European Union,
    [cir] Hong Kong,
    [cir] Singapore; and
     Offer programmatic spot trading of the trading pair \20\ 
and reliably publish trade prices and volumes on a real-time basis 
through Rest and Websocket APIs.
---------------------------------------------------------------------------

    \20\ Trading platforms with programmatic trading offer traders 
an application programming interface that permits trading by sending 
programmed commands to the trading platform.
---------------------------------------------------------------------------

    A Digital Asset Trading Platform is removed as a Constituent 
Trading Platform when it no longer satisfies the Inclusion Criteria. 
The Index Provider does not currently include data from over-the-
counter markets or derivatives platforms among the Constituent Trading 
Platforms. According to the Prospectus, over-the-counter data is not 
currently included because of the potential for trades to include a 
significant premium or discount paid for larger liquidity, which 
creates an uneven comparison relative to more active markets. There is 
also a higher potential for over-the-counter transactions to not be 
arms-length, and thus not be representative of a true market price.
    The Index Provider and the Sponsor have entered into the index 
license agreement, dated as of February 1, 2022 (as amended, the 
``Index License Agreement''), governing the Sponsor's use of the Index 
Price.\21\ Pursuant to the terms of the Index License Agreement, the 
Index Provider may adjust the calculation methodology for the Index 
Price without notice to, or consent of, the Trust or its shareholders. 
The Index Provider may decide to change the calculation methodology to 
maintain the integrity of the Index Price calculation should it 
identify or become aware of previously unknown variables or issues with 
the existing methodology that it believes could materially impact its 
performance and/or reliability. The Index Provider has sole discretion 
over the determination of Index Price and may change the methodologies 
for determining the Index Price from time to time. Shareholders will be 
notified of any material changes to the calculation methodology or the 
Index Price in the Trust's current reports and will be

[[Page 10971]]

notified of all other changes that the Sponsor considers significant in 
the Trust's periodic or current reports. The Sponsor will determine the 
materiality of any changes to the Index Price on a case-by-case basis, 
in consultation with external counsel.
---------------------------------------------------------------------------

    \21\ Upon entering into the Index License Agreement, the Sponsor 
and the Index Provider terminated the license agreement between the 
parties dated as of February 28, 2019.
---------------------------------------------------------------------------

    The Index Provider may change the trading venues that are used to 
calculate the Index or otherwise change the way in which the Index is 
calculated at any time. For example, the Index Provider has scheduled 
quarterly reviews in which it may add or remove Constituent Trading 
Platforms that satisfy or fail the Inclusion Criteria. The Index 
Provider does not have any obligation to consider the interests of the 
Sponsor, the Trust, the shareholders, or anyone else in connection with 
such changes. While the Index Provider is not required to publicize or 
explain the changes or to alert the Sponsor to such changes, it has 
historically notified the Trust (and other subscribers to the Index) of 
any material changes to the Constituent Trading Platforms, including 
any additions or removals, contemporaneous with its issuance of press 
releases in connection with the same. The Sponsor will notify investors 
of any such material event by filing a current report on Form 8-K. 
Although the Index methodology is designed to operate without any 
manual intervention, rare events would justify manual intervention. 
Intervention of this kind would be in response to non-market-related 
events, such as the halting of deposits or withdrawals of funds on a 
Digital Asset Trading Platform, the unannounced closure of operations 
on a Digital Asset Trading Platform, insolvency or the compromise of 
user funds. In the event that such an intervention is necessary, the 
Index Provider would issue a public announcement through its website, 
API and other established communication channels with its clients.
Determination of the Index Price
    The Index applies an algorithm to the price of ADA on the 
Constituent Trading Platforms calculated on a per second basis over a 
24-hour period. The Index's algorithm is expected to reflect a four-
pronged methodology to calculate the Index Price from the Constituent 
Trading Platforms:
     Volume Weighting: Constituent Trading Platforms with 
greater liquidity receive a higher weighting in the Index, increasing 
the ability to execute against (i.e., replicate) the Index in the 
underlying spot markets.
     Price-Variance Weighting: The Index Price reflects data 
points that are discretely weighted in proportion to their variance 
from the rest of the Constituent Trading Platforms. As the price at a 
particular trading platform diverges from the prices at the rest of the 
Constituent Trading Platforms, its weight in the Index Price 
consequently decreases.
     Inactivity Adjustment: The Index Price algorithm penalizes 
stale activity from any given Constituent Trading Platform. When a 
Constituent Trading Platform does not have recent trading data, its 
weighting in the Index Price is gradually reduced until it is de-
weighted entirely. Similarly, once trading activity at a Constituent 
Trading Platform resumes, the corresponding weighting for that 
Constituent Trading Platform is gradually increased until it reaches 
the appropriate level.
     Manipulation Resistance: In order to mitigate the effects 
of wash trading and order book spoofing, the Index only includes 
executed trades in its calculation and the Index only includes 
Constituent Trading Platforms that charge trading fees to its users in 
order to attach a real, quantifiable cost to any manipulation attempts.
    The Index Provider re-evaluates the weighting algorithm on a 
periodic basis, but maintains discretion to change the way in which an 
Index Price is calculated based on its periodic review or in extreme 
circumstances and does not make the exact methodology to calculate the 
Index Price publicly available. Nonetheless, the Sponsors believe that 
the Index is designed to limit exposure to trading or price distortion 
of any individual Digital Asset Trading Platform that experiences 
periods of unusual activity or limited liquidity by discounting, in 
real-time, anomalous price movements at individual Digital Asset 
Trading Platforms.
    The Sponsors believe the Index Provider's selection process for 
Constituent Trading Platforms as well as the methodology of the Index 
Price's algorithm provides a more accurate picture of ADA price 
movements than a simple average of Digital Asset Trading Platform spot 
prices, and that the weighting of ADA prices on the Constituent Trading 
Platforms limits the inclusion of data that is influenced by temporary 
price dislocations that may result from technical problems, limited 
liquidity or fraudulent activity elsewhere in the ADA spot market. By 
referencing multiple trading venues and weighting them based on trade 
activity, the Sponsors believe that the impact of any potential fraud, 
manipulation or anomalous trading activity occurring on any single 
venue is reduced.
    If the Index Price becomes unavailable, or if the Sponsor 
determines in good faith that such Index Price does not reflect an 
accurate price for ADA, then the Sponsor will, on a best efforts basis, 
contact the Index Provider to obtain the Index Price directly from the 
Index Provider. If after such contact such Index Price remains 
unavailable or the Sponsor continues to believe in good faith that such 
Index Price does not reflect an accurate price for ADA, then the 
Sponsor will employ a cascading set of rules to determine the Index 
Price, as described below in ``Determination of the Index Price When 
Index Price is Unavailable.''
    The Trust values its ADA for operational purposes by reference to 
the Index Price. The Index Price is the value of ADA as represented by 
the Index, calculated at 4:00 p.m., New York time, on each business 
day.
Illustrative Example
    For the purposes of illustration, outlined below are examples of 
how the attributes that impact weighting and adjustments in the 
aforementioned methodology may be utilized to generate the Index Price 
for a digital asset. For example, Constituent Trading Platforms used to 
calculate the Index Price of the digital asset may include trading 
platforms such as Coinbase, Kraken, LMAX Digital, and Crypto.com.
    The Index Price algorithm, as described above, is designed to 
account for manipulation at the outset by only including data from 
executed trades on Constituent Trading Platforms that charge trading 
fees. Then, the below-listed elements may impact the weighting of the 
Constituent Trading Platforms on the Index Price as follows:
     Volume Weighting: Each Constituent Trading Platform will 
be weighted to appropriately reflect the trading volume share of the 
Constituent Trading Platform relative to all the Constituent Trading 
Platforms during this same period. For example, an average hourly 
weighting of 67.06%, 14.57%, 11.88%, and 6.49% for Coinbase, Kraken, 
LMAX Digital, and Crypto.com, respectively, would represent each 
Constituent Trading Platform's share of trading volume during the same 
period.
     Inactivity Adjustment: Assume that a Constituent Trading 
Platform represented a 14% weighting on the Index Price of the digital 
asset, which is based on the per-second calculations of its trading 
volume and price-variance relative to the cohort of Constituent Trading 
Platforms included in such Index, and then went offline for 
approximately two hours. The index algorithm would automatically 
recognize inactivity and start de-

[[Page 10972]]

weighting the Constituent Trading Platform at the 3-minute mark and 
continue to do so over a 7-minute period until its influence was 
effectively zero, 10 minutes after becoming inactive. As soon as 
trading activity resumed at the Constituent Trading Platform, the index 
algorithm would re-weight it to the appropriate weighting based on 
trading volume and price-variance relative to the cohort of Constituent 
Trading Platforms included in the Index. Due to the period of 
inactivity, it would re-weight the Constituent Trading Platform 
activity to a weight lower than its original weighting--for example, to 
12%.
     Price-Variance Weighting: The price-variance weighting 
adjustment is a relative measure of each Constituent Trading Platform 
versus the cohort of Constituent Trading Platforms. The further the 
price at a Constituent Trading Platform is from the mean price of the 
cohort, the less influence that trading platform's price will have on 
the algorithm that produces the Index Price, as the trading platform 
data is discretely weighted in proportion to their variance from the 
rest of the trading platforms on a per-second basis and there is no 
minimum threshold the variance must meet for this adjustment to take 
place. For example, assume that for a one-hour period, the digital 
asset's execution prices on one Constituent Trading Platform were 
trading more than 7% higher than the average execution prices on 
another Constituent Trading Platform. The algorithm is designed to 
automatically detect the anomaly (price variance) and reduce that 
specific Constituent Trading Platform's weighting during that one-hour 
period, ensuring a spot reference price that is more reflective of 
broader market activity.
Determination of the Index Price When Index Price Is Unavailable
    The Sponsor uses the following cascading set of rules to calculate 
the Index Price when the Index Price is unavailable.\22\ For the 
avoidance of doubt, the Sponsor will employ the below rules 
sequentially and in the order as presented below, should one or more 
specific rule(s) fail:
---------------------------------------------------------------------------

    \22\ The Sponsor updated these rules on January 11, 2022.
---------------------------------------------------------------------------

    1. Index Price = The price set by the Index as of 4:00 p.m., New 
York time, on the valuation date.\23\ If the Index becomes unavailable, 
or if the Sponsor determines in good faith that the Index does not 
reflect an accurate price, then the Sponsor will, on a best efforts 
basis, contact the Index Provider to obtain the Index Price directly 
from the Index Provider. If after such contact the Index remains 
unavailable or the Sponsor continues to believe in good faith that the 
Index does not reflect an accurate price, then the Sponsor will employ 
the next rule to determine the Index Price. There are no predefined 
criteria to make a good faith assessment and it will be made by the 
Sponsor in its sole discretion.
---------------------------------------------------------------------------

    \23\ The valuation date is any day for which the value of the 
ADA in the Trust may be calculated utilizing the Index Price.
---------------------------------------------------------------------------

    2. Index Price = The price set by Coin Metrics Real-Time Rate (the 
``Secondary Index'') as of 4:00 p.m., New York time, on the valuation 
date (the ``Secondary Index Price''). The Secondary Index Price is a 
real-time reference rate price, calculated using trade data from 
constituent markets selected by Coin Metrics, Inc. (the ``Secondary 
Index Provider''). The Secondary Index Price is calculated by applying 
weighted-median techniques to such trade data where half the weight is 
derived from the trading volume on each constituent market and half is 
derived from inverse price variance, where a constituent market with 
high price variance as a result of outliers or market anomalies 
compared to other constituent markets is assigned a smaller weight. If 
the Secondary Index becomes unavailable, or if the Sponsor determines 
in good faith that the Secondary Index does not reflect an accurate 
price, then the Sponsor will, on a best efforts basis, contact the 
Secondary Index Provider to obtain the Secondary Index Price directly 
from the Secondary Index Provider. If after such contact the Secondary 
Index remains unavailable or the Sponsor continues to believe in good 
faith that the Secondary Index does not reflect an accurate price, then 
the Sponsor will employ the next rule to determine the Index Price. 
There are no predefined criteria to make a good faith assessment and it 
will be made by the Sponsor in its sole discretion.
    3. Index Price = The price set by the Trust's principal market (as 
defined in the Prospectus) (the ``Tertiary Pricing Option'') as of 4:00 
p.m., New York time, on the valuation date. The Tertiary Pricing Option 
is a spot price derived from the principal market's public data feed 
that is believed to be consistently publishing pricing information as 
of 4:00 p.m., New York time, and is provided to the Sponsor via an 
application programming interface. If the Tertiary Pricing Option 
becomes unavailable, or if the Sponsor determines in good faith that 
the Tertiary Pricing Option does not reflect an accurate price, then 
the Sponsor will, on a best efforts basis, contact the Tertiary Pricing 
Provider to obtain the Tertiary Pricing Option directly from the 
Tertiary Pricing Provider. If after such contact the Tertiary Pricing 
Option remains unavailable after such contact or the Sponsor continues 
to believe in good faith that the Tertiary Pricing Option does not 
reflect an accurate price, then the Sponsor will employ the next rule 
to determine the Index Price. There are no predefined criteria to make 
a good faith assessment and it will be made by the Sponsor in its sole 
discretion.
    4. Index Price = The Sponsor will use its best judgment to 
determine a good faith estimate of the Index Price. There are no 
predefined criteria to make a good faith assessment and it will be made 
by the Sponsor in its sole discretion.
    In the event of a fork, the Index Provider may calculate the Index 
Price based on a digital asset that the Sponsor does not believe to be 
an appropriate asset of the Trust (i.e., a digital asset other than 
ADA).\24\ In this event, the Sponsor has full discretion to use a 
different index provider or calculate the Index Price itself using its 
best judgment. In such an event, the Exchange will submit a proposed 
rule filing to contemplate the assets that would subsequently be held 
by the Trust.
---------------------------------------------------------------------------

    \24\ According to the Annual Report, the Cardano Network 
operates using open-source protocols, meaning that any user can 
download the software, modify it and then propose that the users and 
validators of ADA adopt the modification. When a modification is 
introduced and a substantial majority of users and validators' 
consent to the modification, the change is implemented and the 
network remains uninterrupted. However, if less than a substantial 
majority of users and validators' consent to the proposed 
modification, and the modification is not compatible with the 
software prior to its modification, the consequence would be what is 
known as a ``hard fork'' of the Cardano Network, with one group 
running the pre-modified software and the other running the modified 
software. The effect of such a fork would be the existence of two 
versions of ADA running in parallel, yet lacking interchangeability.
---------------------------------------------------------------------------

    The Sponsor may, in its sole discretion, select a different index 
provider, select a different index price provided by the Index 
Provider, calculate the Index Price by using the cascading set of rules 
set forth above, or change the cascading set of rules set forth above 
at any time.\25\
---------------------------------------------------------------------------

    \25\ The Sponsor will provide notice of any such changes in the 
Trust's periodic or current reports and, if the Sponsor makes such a 
change other than on an ad hoc or temporary basis, will file a 
proposed rule change with the Commission.
---------------------------------------------------------------------------

The Structure and Operation of the Trust Protects Investors
    As described below, the Sponsors believe the structure and 
operation of

[[Page 10973]]

the Trust are designed to mitigate fraudulent and manipulative acts and 
practices, to protect investors and the public interest. The Sponsors 
accordingly believe the Commission should approve the listing and 
trading of Shares of the Trust.
Design of the Index
    The Sponsors believe the Index represents an effective means to 
mitigate the impact of potential fraud and manipulation on the 
reference price for ADA. The Index operates materially similarly to 
CoinDesk Bitcoin Price Index (XBX).
    The Sponsors believe that the Index can (i) mitigate the effects of 
fraud, manipulation and other anomalous trading activity on the ADA 
reference rate, (ii) provide a real-time, volume-weighted fair value of 
ADA and (iii) appropriately handle and adjust for non-market related 
events.
    As described in more detail below, the Sponsors believe that the 
Index accomplishes those objectives in the following ways:
    1. The Index tracks the Digital Asset Trading Platform Market price 
through trading activity at Constituent Trading Platforms, the majority 
of which are ``U.S.-Compliant Trading Platforms''; \26\
---------------------------------------------------------------------------

    \26\ ``U.S.-Compliant Trading Platforms'' are trading platforms 
in the Digital Asset Trading Platform Market that are compliant with 
applicable U.S. federal and state licensing requirements and 
practices regarding AML and KYC regulations. All Constituent Trading 
Platforms (except for Bitfinex as detailed above) are U.S.-Compliant 
Trading Platforms. ``Non-U.S.-Compliant Trading Platforms'' are all 
other trading platforms in the Digital Asset Trading Platform 
Market. As of the date of this filing, the U.S.-Compliant Trading 
Platforms that the Index Provider considered for inclusion in the 
Index were Bitstamp, Coinbase, Crypto.com and Kraken. From these 
U.S.-Compliant Trading Platforms, the Index Provider then applies 
additional Inclusion Criteria to determine the Constituent Trading 
Platforms.
---------------------------------------------------------------------------

    2. The Index mitigates the impact of instances of fraud, 
manipulation and other anomalous trading activity in real-time through 
systematic adjustments;
    3. The Index is constructed and maintained by an expert third-party 
index provider, allowing for prudent handling of non-market-related 
events; and
    4. The Index mitigates the impact of instances of fraud, 
manipulation and other anomalous trading activity concentrated on any 
one specific trading platform through a cross-trading platform 
composite index rate.
    1. The Index tracks the Digital Asset Trading Platform Market price 
through trading activity at Constituent Trading Platforms, the majority 
of which are ``U.S.-Compliant Trading Platforms.''
    To reduce the risk of fraud, manipulation, and other anomalous 
trading activity from impacting the Index, the Index Provider 
prioritizes the inclusion of U.S.-Compliant Trading Platforms in the 
Index.
    The Index maintains a minimum number of three trading platforms and 
a maximum number of eight trading platforms to track the Digital Asset 
Trading Platform Market while offering replicability for traders and 
market makers.\27\
---------------------------------------------------------------------------

    \27\ According to the Sponsors, the more trading platforms 
included in the Index, the more ability there is for traders and 
market makers to trade against the Index by arbitraging price 
differences. For example, in the event of variances between ADA 
prices on Constituent Trading Platforms and non-Constituent Trading 
Platforms, arbitrage trading opportunities would exist. These 
discrepancies generally consolidate over time, as price differences 
across trading platforms are realized and capitalized upon by 
traders and market makers.
---------------------------------------------------------------------------

    U.S.-Compliant Trading Platforms possess safeguards that protect 
against fraud and manipulation. For example, U.S.-Compliant Trading 
Platforms regulated by the NYDFS under the BitLicense program are 
required to have regulatory requirements to implement measures designed 
to effectively detect, prevent, and respond to fraud, attempted fraud, 
market manipulation, and similar wrongdoing, and to monitor, control, 
investigate and report back to the NYDFS regarding any wrongdoing.\28\ 
These trading platforms also have the following obligations: \29\
---------------------------------------------------------------------------

    \28\ See, e.g., ``DFS Takes Action to Deter Fraud and 
Manipulation in Virtual Currency Markets,'' available at https://www.dfs.ny.gov/about/press/pr1802071.htm.
    \29\ See ``New York's Final ``BitLicense'' Rule: Overview and 
Changes from July 2014 Proposal,'' June 5, 2015, Davis Polk, 
available at https://www.davispolk.com/files/new_yorks_final_bitlicense_rule_overview_changes_july_2014_proposal.pdf.
---------------------------------------------------------------------------

     Submission of audited financial statements including 
income statements, statements of assets/liabilities, insurance, and 
banking;
     Compliance with capitalization requirements set at NYDFS's 
discretion;
     Prohibitions against the sale or encumbrance to protect 
full reserves of custodian assets;
     Fingerprints and photographs of employees with access to 
customer funds;
     Retention of a qualified Chief Information Security 
Officer and annual penetration testing/audits;
     Documented business continuity and disaster recovery plan, 
independently tested annually; and
     Participation in an independent exam by NYDFS.
    Other U.S.-Compliant Trading Platforms have voluntarily implemented 
certain measures to protect against common forms of market 
manipulation.\30\
---------------------------------------------------------------------------

    \30\ As of the date of this filing, one of the four Constituent 
Trading Platforms, Coinbase, is regulated by NYDFS.
---------------------------------------------------------------------------

    Furthermore, all U.S.-Compliant Trading Platforms are considered 
MSBs that are subject to FinCEN's federal and state reporting 
requirements that provide additional safeguards. For example, 
unscrupulous traders may be less likely to engage in fraudulent or 
manipulative acts and practices on trading platforms that (1) report 
suspicious activity to FinCEN as money services businesses, (2) report 
to state regulators as money transmitters, and/or (3) require customer 
identification through KYC procedures. U.S.-Compliant Trading Platforms 
are required to: \31\
---------------------------------------------------------------------------

    \31\ See BSA Requirements for MSBs, FinCEN website: https://www.fincen.gov/bsarequirements-msbs.
---------------------------------------------------------------------------

     Identify people with ownership stakes or controlling roles 
in the MSB;
     Establish a formal Anti-Money Laundering (AML) policy in 
place with documentation, training, independent review, and a named 
compliance officer;
     Implement strict customer identification and verification 
policies and procedures;
     File Suspicious Activity Reports (SARs) for suspicious 
customer transactions;
     File Currency Transaction Reports (CTRs) for cash-in or 
cash-out transactions greater than $10,000; and
     Maintain a five-year record of currency exchanges greater 
than $1,000 and money transfers greater than $3,000.
    2. The Index mitigates the impact of instances of fraud, 
manipulation, and other anomalous trading activity in real-time through 
systematic adjustments.
    The Index is calculated once every second according to a systematic 
methodology that relies on observed trading activity on the Constituent 
Trading Platforms. While the precise methodology underlying the Index 
is currently proprietary, the key elements of the Index are outlined 
below:
     Volume Weighting: Constituent Trading Platforms with 
greater liquidity receive a higher weighting in the Index, increasing 
the ability to execute against (i.e., replicate) the Index in the 
underlying spot markets.
     Price-Variance Weighting: The Index reflects data points 
that are discretely weighted in proportion to their variance from the 
rest of the Constituent Trading Platforms. As the price at a 
Constituent Trading Platform diverges from the prices at the rest of 
the Constituent Trading Platforms, its

[[Page 10974]]

weight in the Index consequently decreases.
     Inactivity Adjustment: The Index algorithm penalizes stale 
activity from any given Constituent Trading Platform. When a 
Constituent Trading Platform does not have recent trading data, its 
weighting in the Index is gradually reduced, until it is de-weighted 
entirely. Similarly, once trading activity at the Constituent Trading 
Platform resumes, the corresponding weighting for that Constituent 
Trading Platform is gradually increased until it reaches the 
appropriate level.
     Manipulation Resistance: In order to mitigate the effects 
of wash trading and order book spoofing, the Index only includes 
executed trades in its calculation and the Index only includes 
Constituent Trading Platforms that charge trading fees to its users in 
order to attach a real, quantifiable cost to any manipulation attempts.
    The Index Provider reviews and periodically updates the Constituent 
Trading Platforms included in the Index by utilizing a methodology that 
is guided by the IOSCO principles for financial benchmarks.
    3. The Index is constructed and maintained by an expert third-party 
index provider, allowing for prudent handling of non-market-related 
events.
    The Index Provider reviews and periodically updates which trading 
platforms are included in the Index by utilizing a methodology that is 
guided by the IOSCO principles for financial benchmarks.
    According to the Index methodology, for a trading platform to 
become a Constituent Trading Platform, it must satisfy each of the 
following Inclusion Criteria:
     Sufficient USD or USDC liquidity relative to the size of 
the listed assets;
     No evidence in the past 12 months of trading restrictions 
on individuals or entities that would otherwise meet the trading 
platform's eligibility requirements to trade;
     No evidence in the past 12 months of undisclosed 
restrictions on deposits or withdrawals from user accounts;
     Real-time price discovery;
     Limited or no capital controls;
     Transparent ownership including a publicly-known ownership 
entity;
     Publicly available language and policies addressing legal 
and regulatory compliance in the U.S., including KYC, AML and other 
policies designed to comply with relevant regulations that might apply 
to it; \32\
---------------------------------------------------------------------------

    \32\ To the extent a Digital Asset Trading Platform does not 
service U.S. customers, it will still be eligible for inclusion in 
the Index so long as it has publicly available language and policies 
addressing legal and regulatory compliance, including KYC, AML and 
other policies designed to comply with regulations applicable to 
such platform.
---------------------------------------------------------------------------

     Be a trading platform that is licensed and able to service 
investors in one or more of the following jurisdictions:
    [cir] United States,
    [cir] United Kingdom,
    [cir] European Union,
    [cir] Hong Kong,
    [cir] Singapore; and
     Offer programmatic spot trading of the trading pair and 
reliably publish trade prices and volumes on a real-time basis through 
Rest and Websocket APIs.
    Although the Index methodology is designed to operate without any 
human interference, rare events would justify manual intervention. 
Manual intervention would only be in response to ``non-market-related 
events'' (e.g., halting of deposits or withdrawals of funds, 
unannounced closure of trading platform operations, insolvency, 
compromise of user funds, etc.). In the event that such an intervention 
is necessary, the Index Provider would issue a public announcement 
through its website, API and other established communication channels 
with its clients.\33\
---------------------------------------------------------------------------

    \33\ To the extent any such intervention has a material impact 
on the Trust, the Sponsor will also issue a public announcement.
---------------------------------------------------------------------------

    4. The Index mitigates the impact of instances of fraud, 
manipulation and other anomalous trading activity concentrated on any 
one specific trading platform through a cross-trading platform 
composite index rate.
    The Index is based on the price and volume data of multiple 
Constituent Trading Platforms that satisfy the Index Provider's 
Inclusion Criteria. By referencing multiple trading venues and 
weighting them based on trade activity, the impact of any potential 
fraud, manipulation, or anomalous trading activity occurring on any 
single venue is reduced. Specifically, the effects of fraud, 
manipulation, or anomalous trading activity occurring on any single 
venue are de-weighted and consequently diluted by non-anomalous trading 
activity from other Constituent Trading Platforms.
    Although the Index is designed to accurately capture the market 
price of ADA, third parties may be able to purchase and sell ADA on 
public or private markets not included among the constituent Digital 
Asset Trading Platforms of the Index, and such transactions may take 
place at prices materially higher or lower than the Index Price. 
Moreover, there may be variances in the prices of ADA on the various 
Digital Asset Trading Platforms, including as a result of differences 
in fee structures or administrative procedures on different Digital 
Asset Trading Platforms. For example, based on data provided by the 
Index Provider, on any given day during the twelve months ended 
December 31, 2024, the maximum differential between the 4:00 p.m., New 
York time spot price of any single Digital Asset Trading Platform 
included in the Index and the Index Price was 2.07% and the average of 
the maximum differentials of the 4:00 p.m., New York time spot price of 
each Digital Asset Trading Platform included in the Index and the Index 
Price was 0.90%. During this same period, the average differential 
between the 4:00 p.m., New York time spot prices of all the Digital 
Asset Trading Platforms included in the Index and the Index Price was 
0.01%. All Digital Asset Trading Platforms that were included in the 
Index throughout the period were considered in this analysis.
    Additionally, given pricing on the Digital Asset Trading Platforms 
is known to the market, the Sponsors believe that, even if efforts to 
manipulate the price of ADA at 4:00 p.m., Eastern Time (``E.T.''). were 
successful on a Digital Asset Trading Platform, the effect of such 
activity on the pricing of the Trust would be mitigated due to the 
controls embedded in the structure of the Index.
    Accordingly, the Sponsors believe that the Index has proven its 
ability to (i) mitigate the effects of fraud, manipulation and other 
anomalous trading activity on the ADA reference rate, (ii) provide a 
real-time, volume-weighted fair value of ADA and (iii) appropriately 
handle and adjust for non-market related events.
Creation and Redemption of Shares
    Authorized Participants may submit orders to create or redeem 
Shares under procedures for ``Cash Orders.''
    The Authorized Participants will deliver only cash to create Shares 
and will receive only cash when redeeming Shares. Further, Authorized 
Participants will not directly or indirectly purchase, hold, deliver, 
or receive ADA as part of the creation or redemption process or 
otherwise direct the Trust or a third party with respect to purchasing, 
holding, delivering, or receiving ADA as part of the creation or 
redemption process.
    The Trust will create Shares by receiving ADA from a third party 
that is not the Authorized Participant, and the Trust, or an affiliate 
of the Trust (and in any event not the Authorized Participant), is 
responsible for selecting

[[Page 10975]]

the third party to deliver the ADA. Further, the third party will not 
be acting as an agent of the Authorized Participant with respect to the 
delivery of the ADA to the Trust nor acting at the direction of the 
Authorized Participant with respect to the delivery of the ADA to the 
Trust. The Trust will redeem Shares by delivering ADA to a third party 
that is not the Authorized Participant, and the Trust, or an affiliate 
of the Trust (and in any event not the Authorized Participant), is 
responsible for selecting the third party to receive the ADA. Further, 
the third party will not be acting as an agent of the Authorized 
Participant with respect to the receipt of the ADA from the Trust nor 
acting at the direction of the Authorized Participant with respect to 
the receipt of the ADA from the Trust.
    Cash Orders are made through the participation of a Liquidity 
Provider \34\ who obtains or receives ADA in exchange for cash, and are 
facilitated by the Transfer Agent and Grayscale Investments Sponsors, 
LLC, acting in its capacity as the Liquidity Engager. Liquidity 
Providers are not party to the Participant Agreements (as defined 
below) and are engaged separately by the Liquidity Engager.
---------------------------------------------------------------------------

    \34\ A ``Liquidity Provider'' means one or more eligible 
companies that facilitate the purchase and sale of ADA in connection 
with creations or redemptions pursuant to Cash Orders. The Liquidity 
Providers with which Grayscale Investments Sponsors, LLC, acting 
other than in its capacity as the Sponsor (in such other capacity, 
the ``Liquidity Engager'') will engage in ADA transactions are third 
parties that are not affiliated with the Sponsor or the Trust and 
are not acting as agents of the Trust, the Sponsor, or any 
Authorized Participant, and all transactions will be done on an 
arms-length basis. Except for the contractual relationships between 
each Liquidity Provider and Grayscale Investments Sponsors, LLC in 
its capacity as the Liquidity Engager, there is no contractual 
relationship between each Liquidity Provider and the Trust, the 
Sponsor, or any Authorized Participant. When seeking to buy ADA in 
connection with creations or sell ADA in connection with 
redemptions, the Liquidity Engager will seek to obtain commercially 
reasonable prices and terms from the approved Liquidity Providers. 
Once agreed upon, the transaction will generally occur on an ``over-
the-counter'' basis.
---------------------------------------------------------------------------

    According to the Registration Statement, the Trust creates Baskets 
(as described below) of Shares only upon receipt of ADA and redeems 
Shares only by distributing ADA. ``Authorized Participants'' are the 
only persons that may place orders to create and redeem Baskets. Each 
Authorized Participant must (i) be a registered broker-dealer and (ii) 
enter into an agreement with the Sponsor and Transfer Agent that 
provides the procedures for the creation and redemption of Baskets and 
for the delivery of ADA required for the creation and redemption of 
Baskets via a Liquidity Provider (each, a ``Participant Agreement''). 
An Authorized Participant may act for its own account or as agent for 
broker-dealers, custodians and other securities market participants 
that wish to create or redeem Baskets. Shareholders who are not 
Authorized Participants will only be able to create or redeem their 
Shares through an Authorized Participant.
    The Trust issues Shares to and redeems Shares from Authorized 
Participants on an ongoing basis, but only in one or more ``Baskets'' 
(with a Basket being a block of 10,000 Shares). The Trust will not 
issue fractions of a Basket.
    The creation and redemption of Baskets will be made only in 
exchange for the delivery to the Trust, or the distribution by the 
Trust, of the number of whole and fractional ADA represented by each 
Basket being created or redeemed, which is determined by dividing (x) 
the number of ADA owned by the Trust at 4:00 p.m., New York time, on 
the trade date of a creation or redemption order, after deducting the 
number of ADA representing the U.S. dollar value of accrued but unpaid 
fees and expenses of the Trust (converted using the Index Price at such 
time, and carried to the eighth decimal place), by (y) the number of 
Shares outstanding at such time (with the quotient so obtained 
calculated to one one-hundred-millionth of one ADA (i.e., carried to 
the eighth decimal place)), and multiplying such quotient by 10,000 
(the ``Basket Amount''). The U.S. dollar value of a Basket is 
calculated by multiplying the Basket Amount by the Index Price as of 
the trade date (the ``Basket NAV''). The Basket NAV multiplied by the 
number of Baskets being created or redeemed is referred to as the 
``Total Basket NAV.'' All questions as to the calculation of the Basket 
Amount will be conclusively determined by the Sponsor and will be final 
and binding on all persons interested in the Trust. The number of ADA 
represented by a Share will gradually decrease over time as the Trust's 
ADA are used to pay the Trust's expenses.
    The creation of Baskets requires the delivery by the Authorized 
Participant of a cash amount equivalent to the Total Basket Amount and 
the redemption of Baskets requires the distribution to the Authorized 
Participant of a cash amount equivalent to the Total Basket Amount.
    Although the Trust creates Baskets only upon the receipt of ADA, 
and redeems Baskets only by distributing ADA, an Authorized Participant 
will submit Cash Orders, pursuant to which the Authorized Participant 
will deposit cash with, or accept cash from, the Transfer Agent in 
connection with the creation and redemption of Baskets.
    Cash Orders will be facilitated by the Transfer Agent and Liquidity 
Engager, acting other than in its capacity as Sponsor. On an order-by-
order basis, the Liquidity Engager will engage one or more Liquidity 
Providers to obtain or receive ADA in exchange for cash in connection 
with such order, as described in more detail below.
    Unless the Sponsor requires that a Cash Order be effected at actual 
execution prices (an ``Actual Execution Cash Order''),\35\ each 
Authorized Participant that submits a Cash Order to create or redeem 
Baskets (a ``Variable Fee Cash Order'') \36\ will pay a fee (the 
``Variable Fee'') based on the Total Basket NAV, and any price 
differential of ADA between the trade date and the settlement date will 
be borne solely by the Liquidity Provider until such ADA have been 
received or liquidated by the Trust. The Variable Fee is intended to 
cover all of a Liquidity Provider's expenses in connection with the 
creation or redemption order, including any ADA trading platform fees 
that the Liquidity Provider incurs in connection with buying or selling 
ADA. The amount may be changed by the Sponsor in its sole discretion at 
any time, and Liquidity Providers will communicate to the Sponsor in 
advance the Variable Fee they would be willing to accept in connection 
with a Variable Fee Cash Order, based on market conditions and

[[Page 10976]]

other factors existing at the time of such Variable Fee Cash Order.
---------------------------------------------------------------------------

    \35\ With respect to a creation or redemption pursuant to an 
Actual Execution Cash Order, as between the Trust and an Authorized 
Participant, the Authorized Participant is responsible for the 
dollar cost of the difference between the ADA price utilized in 
calculating Total Basket NAV on the trade date and the price at 
which the Trust acquires or disposes of the ADA on the settlement 
date. If the price realized in acquiring or disposing of the 
corresponding Total Basket Amount is higher than the Total Basket 
NAV, the Authorized Participant will bear the dollar cost of such 
difference, in the case of a creation, by delivering cash in the 
amount of such shortfall (the ``Additional Creation Cash'') to the 
Cash Account or, in the case of a redemption, with the amount of 
cash to be delivered to the Authorized Participant being reduced by 
the amount of such difference (the ``Redemption Cash Shortfall''). 
If the price realized in acquiring the corresponding Total Basket 
Amount is lower than the Total Basket NAV, the Authorized 
Participant will benefit from such difference, with the Trust 
promptly returning cash in the amount of such excess (the ``Excess 
Creation Cash'') to the Authorized Participant.
    \36\ Unless the Sponsor determines otherwise in its sole 
discretion based on market conditions and other factors existing at 
the time of such Cash Order, all creations and redemptions pursuant 
to Cash Orders are expected to be executed as Variable Fee Cash 
Orders, and any price differential of ADA between the trade date and 
the settlement date will be borne solely by the Liquidity Provider 
until such ADA have been received by the Trust.
---------------------------------------------------------------------------

    Alternatively, the Sponsor may require that a Cash Order be 
effected as an Actual Execution Cash Order, in its sole discretion 
based on market conditions and other factors existing at the time of 
such Cash Order, and under such circumstances, any price differential 
of ADA between the trade date and the settlement date will be borne 
solely by the Authorized Participant until such ADA have been received 
or liquidated by the Trust.
    In the case of creations, to transfer the Total Basket Amount to 
the Trust's Digital Asset Account, the Liquidity Provider will transfer 
ADA to one of the public key addresses associated with the Digital 
Asset Account and as provided by the Sponsor. In the case of 
redemptions, the same procedure is conducted, but in reverse, using the 
public key addresses associated with the wallet of the Liquidity 
Provider and as provided by such party. All such transactions will be 
conducted on the Cardano Blockchain and parties acknowledge and agree 
that such transfers may be irreversible if done incorrectly.
    Authorized Participants do not pay a transaction fee to the Trust 
in connection with the creation or redemption of Baskets, but there may 
be transaction fees associated with the validation of the transfer of 
ADA by the Cardano Network, which will be paid by the Custodian in the 
case of redemptions and the Authorized Participant or the Liquidity 
Provider in the case of creations. Service providers may charge 
Authorized Participants administrative fees for order placement and 
other services related to creation of Baskets. As discussed above, 
Authorized Participants will also pay the Variable Fee in connection 
with Variable Fee Cash Orders. Under certain circumstances, Authorized 
Participants may also be required to deposit additional cash in the 
Cash Account, or be entitled to receive excess cash from the Cash 
Account, in connection with creations and redemptions pursuant to 
Actual Execution Cash Orders. Authorized Participants will receive no 
fees, commissions or other form of compensation or inducement of any 
kind from either the Sponsor or the Trust and no such person has any 
obligation or responsibility to the Sponsor or the Trust to effect any 
sale or resale of Shares.
    The following is a summary of the procedures for the creation and 
redemption of Baskets.
Creation Procedures
    On any business day, an Authorized Participant may place an order 
with the Transfer Agent to create one or more Baskets.
    Cash Orders for creation must be placed with the Transfer Agent no 
later than 1:59:59 p.m., New York time.
    The Sponsor may in its sole discretion limit the number of Shares 
created pursuant to Cash Orders on any specified day without notice to 
the Authorized Participants and may direct the Marketing Agent to 
reject any Cash Orders in excess of such capped amount. In exercising 
its discretion to limit the number of Shares created pursuant to Cash 
Orders, the Sponsor expects to take into consideration a number of 
factors, including the availability of Liquidity Providers to 
facilitate Cash Orders and the cost of processing Cash Orders.
    Creations under Cash Orders will take place as follows, where ``T'' 
is the trade date and each day in the sequence must be a business day. 
Before a creation order is placed, the Sponsor determines if such 
creation order will be a Variable Fee Cash Order or an Actual Execution 
Cash Order, which determination is communicated to the Authorized 
Participant.

* The ``Cash Account'' means the account maintained by the Transfer
  Agent for purposes of receiving cash from, and distributing cash to,
  Authorized Participants in connection with creations and redemptions
  pursuant to Cash Orders. For the avoidance of doubt, the Trust shall
  have no interest (beneficial, equitable or otherwise) in the Cash
  Account or any cash held therein.

Redemption Procedures
    The procedures by which an Authorized Participant can redeem one or 
more Baskets mirror the procedures for the creation of Baskets. On any 
business day, an Authorized Participant may place a redemption order 
specifying the number of Baskets to be redeemed.
    The redemption of Shares pursuant to Cash Orders will only take 
place if approved by the Sponsor in writing, in its sole discretion and 
on a case-by-case basis. In exercising its discretion to approve the 
redemption of Shares pursuant to Cash Orders, the Sponsor expects to 
take into consideration a number of factors, including the availability 
of Liquidity Providers to facilitate Cash Orders and the cost of 
processing Cash Orders.
    Cash Orders for redemption must be placed no later than 1:59:59 
p.m., New York time on each business day. The Authorized Participants 
may only redeem Baskets and cannot redeem any Shares in an amount less 
than a Basket.

[[Page 10977]]

    Redemptions under Cash Orders will take place as follows, where 
``T'' is the trade date and each day in the sequence must be a business 
day. Before a redemption order is placed, the Sponsor determines if 
such redemption order will be a Variable Fee Cash Order or an Actual 
Execution Cash Order, which determination is communicated to the 
Authorized Participant.

------------------------------------------------------------------------

Suspension or Rejection of Orders and Total Basket Amount
    The creation or redemption of Shares may be suspended generally, or 
refused with respect to particular requested creations or redemptions, 
during any period when the transfer books of the Transfer Agent are 
closed or if circumstances outside the control of the Sponsor or its 
delegates make it for all practicable purposes not feasible to process 
creation orders or redemption orders or for any other reason at any 
time or from time to time.\37\ The Transfer Agent may reject an order 
or, after accepting an order, may cancel such order if: (i) such order 
is not presented in proper form as described in the Participant 
Agreement, (ii) the transfer of the Total Basket Amount comes from an 
account other than a ADA wallet address that is known to the Custodian 
as belonging to a Liquidity Provider or (iii) the fulfillment of the 
order, in the opinion of counsel, might be unlawful, among other 
reasons. None of the Sponsor or its delegates will be liable for the 
suspension, rejection or acceptance of any creation order or redemption 
order.
---------------------------------------------------------------------------

    \37\ Extenuating circumstances outside of the control of the 
Sponsor and its delegates or that could cause the transfer books of 
the Transfer Agent to be closed are outlined in the Participant 
Agreement and include, for example, public service or utility 
problems, power outages resulting in telephone, telecopy and 
computer failures, acts of God such as fires, floods or extreme 
weather conditions, market conditions or activities causing trading 
halts, systems failures involving computer or other information 
systems, including any failures or outages of the Cardano Network, 
affecting the Authorized Participant, the Sponsor, the Trust, the 
Transfer Agent, the Marketing Agent and the Custodian and similar 
extraordinary events.
---------------------------------------------------------------------------

Availability of Information
    The Trust's website (https://grayscale.com/crypto-products/grayscale-cardano-trust/) will include quantitative information on a 
per Share basis updated on a daily basis, including, (i) the current 
NAV per Share daily and the prior business day's NAV per Share and the 
reported closing price of the Shares; (ii) the mid-point of the bid-ask 
price \38\ as of the time the NAV per Share is calculated (``Bid-Ask 
Price'') and a calculation of the premium or discount of such price 
against such NAV per Share; and (iii) data in chart format displaying 
the frequency distribution of discounts and premiums of the daily Bid-
Ask Price against the NAV per Share, within appropriate ranges, for 
each of the four previous calendar quarters (or for as long as the 
Trust has been trading as an ETP if shorter). In addition, on each 
business day the Trust's website will provide pricing information for 
the Shares.
---------------------------------------------------------------------------

    \38\ The bid-ask price of the Trust is determined using the 
highest bid and lowest offer on the Consolidated Tape as of the time 
of calculation of the closing day NAV.
---------------------------------------------------------------------------

    One or more major market data vendors, will provide an intra-day 
indicative value (``IIV'') per Share updated every 15 seconds, as 
calculated by the Exchange or a third party financial data provider 
during the Exchange's Core Trading Session (9:30 a.m. to 4:00 p.m., 
E.T.). The IIV will be calculated using the same methodology as the NAV 
per Share of the Trust (as described above), specifically by using the 
prior day's closing NAV per Share as a base and updating that value 
during the NYSE Arca Core Trading Session to reflect changes in the 
value of the Index during the trading day.
    The IIV disseminated during the NYSE Arca Core Trading Session 
should not be viewed as an actual real-time update of the NAV per 
Share, which will be calculated only once at the end of each trading 
day. The IIV will be widely disseminated on a per Share basis every 15 
seconds during the NYSE Arca Core Trading Session by one or more major 
market data vendors. In addition, the IIV will be available through on-
line information services.
    The NAV for the Trust will be calculated by the Sponsor once a day 
and will be disseminated daily to all market participants at the same 
time. To the extent that the Sponsor has utilized the cascading set of 
rules described in ``Index Price'' above, the Trust's website will note 
the valuation methodology used and the price per ADA resulting from 
such calculation. Quotation and last-sale information regarding the 
Shares will be disseminated through the facilities of the Consolidated 
Tape Association (``CTA'').
    Quotation and last sale information for ADA will be widely 
disseminated through a variety of major market data vendors, including 
Bloomberg and Reuters. In addition, real-time price (and volume) data 
for ADA is available by subscription from Reuters and Bloomberg. The 
spot price of ADA is available on a 24-hour basis from major market 
data vendors, including Bloomberg and Reuters. Information relating to 
trading, including price and volume information, in ADA will be 
available from major market data vendors and from the trading platforms

[[Page 10978]]

on which ADA are traded. The normal trading hours for Digital Asset 
Trading Platforms are 24-hours per day, 365-days per year.
    On each business day, the Sponsor will publish the Index Price, the 
Trust's NAV, and the NAV per Share on the Trust's website as soon as 
practicable after its determination. If the NAV and NAV per Share have 
been calculated using a price per ADA other than the Index Price for 
such Evaluation Time, the publication on the Trust's website will note 
the valuation methodology used and the price per ADA resulting from 
such calculation.
    The Trust will provide website disclosure of its NAV daily. The 
website disclosure of the Trust's NAV will occur at the same time as 
the disclosure by the Sponsor of the NAV to Authorized Participants so 
that all market participants are provided such portfolio information at 
the same time. Therefore, the same portfolio information will be 
provided on the public website as well as in electronic files provided 
to Authorized Participants. Accordingly, each investor will have access 
to the current NAV of the Trust through the Trust's website, as well as 
from one or more major market data vendors.
    The value of the Index, as well as additional information regarding 
the Index, will be available on a continuous basis.
    Information regarding market price and trading volume of the Shares 
will be continually available on a real-time basis throughout the day 
on brokers' computer screens and other electronic services.
    Information regarding the previous day's closing price and trading 
volume information for the Shares will be published daily in the 
financial section of newspapers.
Trading Rules
    The Exchange deems the Shares to be equity securities, thus 
rendering trading in the Shares subject to the Exchange's existing 
rules governing the trading of equity securities. Shares will trade on 
the NYSE Arca Marketplace from 4:00 a.m. to 8:00 p.m., E.T. in 
accordance with NYSE Arca Rule 7.34-E (Early, Core, and Late Trading 
Sessions). The Exchange has appropriate rules to facilitate 
transactions in the Shares during all trading sessions. As provided in 
NYSE Arca Rule 7.6-E, the minimum price variation (``MPV'') for quoting 
and entry of orders in equity securities traded on the NYSE Arca 
Marketplace is $0.01, with the exception of securities that are priced 
less than $1.00, for which the MPV for order entry is $0.0001.
    The Shares will conform to the initial and continued listing 
criteria under NYSE Arca Rule 8.201-E. The trading of the Shares will 
be subject to NYSE Arca Rule 8.201-E(g), which sets forth certain 
restrictions on Equity Trading Permit Holders (``ETP Holders'') acting 
as registered Market Makers in Commodity-Based Trust Shares to 
facilitate surveillance. The Exchange represents that, for initial and 
continued listing, the Trust will be in compliance with Rule 10A-3 \39\ 
under the Act, as provided by NYSE Arca Rule 5.3-E. A minimum of 
100,000 Shares of the Trust will be outstanding at the commencement of 
trading on the Exchange.
---------------------------------------------------------------------------

    \39\ 17 CFR 240.10A-3.
---------------------------------------------------------------------------

Trading Halts
    With respect to trading halts, the Exchange may halt or suspend 
trading in the Shares of the Trust in accordance with its rules. 
Additionally, trading in Shares of the Trust will be halted if the 
circuit breaker parameters in NYSE Arca Rule 7.12-E have been reached. 
Trading also may be halted because of market conditions or for reasons 
that, in the view of the Exchange, make trading in the Shares 
inadvisable.
    The Exchange may halt trading during the day in which an 
interruption to the dissemination of the IIV or the value of the Index 
occurs. If the interruption to the dissemination of the IIV or the 
value of the Index persists past the trading day in which it occurred, 
the Exchange will halt trading no later than the beginning of the 
trading day following the interruption. In addition, if the Exchange 
becomes aware that the NAV per Share is not disseminated to all market 
participants at the same time, it will halt trading in the Shares until 
such time as the NAV per Share is available to all market participants.
Surveillance
    The Exchange represents that trading in the Shares of the Trust on 
the Exchange will be subject to the existing trading surveillances 
administered by the Exchange, as well as cross-market surveillances 
administered by the Financial Industry Regulatory Authority (``FINRA'') 
on behalf of the Exchange, which are designed to detect potential 
violations of Exchange rules and applicable federal securities laws 
with respect to the Shares of the Trust trading on the Exchange.\40\ 
The Exchange represents that these procedures are adequate to properly 
monitor Exchange trading of the Shares in all trading sessions and to 
deter and detect violations of Exchange rules and federal securities 
laws with respect to the Shares of the Trust trading on the Exchange.
---------------------------------------------------------------------------

    \40\ FINRA conducts cross-market surveillances on behalf of the 
Exchange pursuant to a regulatory services agreement. The Exchange 
is responsible for FINRA's performance under this regulatory 
services agreement.
---------------------------------------------------------------------------

    The existing surveillances referred to above generally focus on 
detecting securities trading outside their normal trading patterns, 
which could be indicative of manipulative or other violative activity 
with respect to the Shares of the Trust. When such situations are 
detected, surveillance analysis follows and investigations are opened, 
where appropriate, to review the behavior of all relevant parties for 
all relevant trading violations.
    The Exchange or FINRA, on behalf of the Exchange, or both, may 
communicate regarding trading in the Shares with other markets and 
other entities that are members of the Intermarket Surveillance Group 
(``ISG''). The Exchange or FINRA, on behalf of the Exchange, or both, 
may obtain trading information regarding trading in the Shares and ADA 
derivatives from such markets and other entities. In addition, the 
Exchange may obtain information regarding trading in the Shares and ADA 
derivatives from markets and other entities with which the Exchange has 
in place a comprehensive surveillance sharing agreement (``CSSA'').\41\ 
The Exchange is also able to obtain information from ETP Holders 
regarding their trading (as principal or agent) in the Shares and any 
underlying ADA, options on ADA futures, or any other ADA 
derivatives.\42\
---------------------------------------------------------------------------

    \41\ For a list of the current members of ISG, see 
www.isgportal.org. The Exchange notes that not all components of the 
Trust may trade on markets that are members of ISG or with which the 
Exchange has in place a CSSA.
    \42\ See NYSE Arca Rule 10.8210.
---------------------------------------------------------------------------

    In addition, under NYSE Arca Rule 8.201-E(g), an ETP Holder acting 
as a registered Market Maker in the Shares is required to provide the 
Exchange with information relating to its accounts for trading in any 
underlying commodity, related futures or options on futures, or any 
other related derivatives. Commentary .04 of NYSE Arca Rule 11.3-E 
requires an ETP Holder acting as a registered Market Maker, and its 
affiliates, in the Shares to establish, maintain and enforce written 
policies and procedures reasonably designed to prevent the misuse of 
any material nonpublic information with respect to such products, any 
components of the related products, any physical asset or commodity 
underlying the product, applicable currencies, underlying indexes, 
related futures or options on

[[Page 10979]]

futures, and any related derivative instruments (including the Shares). 
As a general matter, the Exchange has regulatory jurisdiction over its 
ETP Holders and their associated persons, which include any person or 
entity controlling an ETP Holder. To the extent the Exchange may be 
found to lack jurisdiction over a subsidiary or affiliate of an ETP 
Holder that does business only in commodities or futures contracts and 
that subsidiary or affiliate is a member of another regulatory 
organization, the Exchange could obtain information regarding the 
activities of such subsidiary or affiliate through surveillance sharing 
agreements with regulatory organizations to the extent the Exchange has 
such an agreement with that regulatory organization.
    In addition, the Exchange also has a general policy prohibiting the 
distribution of material, non-public information by its employees.
    All statements and representations made in this filing regarding 
(a) the description of the index, portfolio, or reference assets of the 
Trust, (b) limitations on index or portfolio holdings or reference 
assets, or (c) the applicability of Exchange listing rules specified in 
this rule filing shall constitute continued listing requirements for 
listing the Shares on the Exchange.
    The Sponsor has represented to the Exchange that it will advise the 
Exchange of any failure by the Trust to comply with the continued 
listing requirements, and, pursuant to its obligations under Section 
19(g)(1) of the Act, the Exchange will monitor for compliance with the 
continued listing requirements. If the Trust is not in compliance with 
the applicable listing requirements, the Exchange will commence 
delisting procedures under NYSE Arca Rule 5.5-E(m).
Information Bulletin
    Prior to the commencement of trading, the Exchange will inform its 
ETP Holders in an ``Information Bulletin'' of the special 
characteristics and risks associated with trading the Shares. 
Specifically, the Information Bulletin will discuss the following: (1) 
the procedures for creations of Shares in Baskets; (2) NYSE Arca Rule 
9.2-E(a), which imposes a duty of due diligence on its ETP Holders to 
learn the essential facts relating to every customer prior to trading 
the Shares; (3) information regarding how the value of the Index and 
NAV are disseminated; (4) the possibility that trading spreads and the 
resulting premium or discount on the Shares may widen during the 
Opening and Late Trading Sessions, when an updated IIV will not be 
calculated or publicly disseminated; (5) the requirement that members 
deliver a prospectus to investors purchasing newly issues Shares prior 
to or concurrently with the confirmation of a transaction; and (6) 
trading information. The Exchange notes that investors purchasing 
Shares directly from the Trust will receive a prospectus.
    In addition, the Information Bulletin will reference that the Trust 
is subject to various fees and expenses as described in the Prospectus. 
The Information Bulletin will disclose that information about the 
Shares of the Trust is publicly available on the Trust's website.
    The Information Bulletin will also discuss any relief, if granted, 
by the Commission or the staff from any rules under the Act.
2. Statutory Basis
    The basis under the Act for this proposed rule change is the 
requirement under Section 6(b)(5) \43\ that an exchange have rules that 
are designed to prevent fraudulent and manipulative acts and practices, 
to promote just and equitable principles of trade, to remove 
impediments to, and perfect the mechanism of a free and open market 
and, in general, to protect investors and the public interest.
---------------------------------------------------------------------------

    \43\ 15 U.S.C. 78f(b)(5).
---------------------------------------------------------------------------

    The Exchange believes that the proposed rule change is designed to 
prevent fraudulent and manipulative acts and practices in that the 
Shares will be listed and traded on the Exchange pursuant to the 
initial and continued listing criteria in NYSE Arca Rule 8.201-E. The 
Exchange has in place certain surveillance procedures that are adequate 
to properly monitor trading in the Shares on the Exchange in all 
trading sessions and to deter and detect violations of Exchange rules 
and federal securities laws applicable to the Shares of the Trust 
trading on the Exchange. The Exchange or FINRA, on behalf of the 
Exchange, or both, will communicate as needed regarding trading in the 
Shares with other markets that are members of the ISG, and the Exchange 
or FINRA, on behalf of the Exchange, or both, may obtain trading 
information regarding trading in the Shares from such markets. In 
addition, the Exchange may obtain information regarding trading in the 
Shares from markets with which the Exchange has in place a CSSA. Also, 
pursuant to NYSE Arca rules, the Exchange is able to obtain information 
from ETP Holders regarding their trading (as principal or agent) in the 
Shares and any underlying ADA, options on ADA futures, or any ADA 
derivatives.
    The proposed rule change is also designed to prevent fraudulent and 
manipulative acts and practices in connection with trading in the 
Shares on the Exchange because it (1) tracks the Digital Asset Trading 
Platform Market price through trading activity at Constituent Trading 
Platforms, the majority of which are U.S.-Compliant Trading Platforms; 
(2) mitigates the impact of instances of fraud, manipulation and other 
anomalous trading activity in real-time through systematic adjustments; 
(3) is constructed and maintained by an expert third-party index 
provider, allowing for prudent handling of non-market-related events; 
and (4) mitigates the impact of instances of fraud, manipulation and 
other anomalous trading activity concentrated on any one specific 
trading platform through a cross-trading platform composite index rate. 
The Index has proven its ability to (i) mitigate the effects of fraud, 
manipulation and other anomalous trading activity from impacting the 
ADA reference rate, (ii) provide a real-time, volume-weighted fair 
value of ADA and (iii) appropriately handle and adjust for non-market 
related events.
    The proposed rule change is designed to promote just and equitable 
principles of trade and to protect investors and the public interest in 
that there is a considerable amount of ADA price and market information 
available on public websites and through professional and subscription 
services. Investors may obtain, on a 24-hour basis, ADA pricing 
information based on the spot price for ADA from various financial 
information service providers. The closing price and settlement prices 
of ADA are readily available from the Digital Asset Trading Platforms 
and other publicly available websites. In addition, such prices are 
published in public sources, or on-line information services such as 
Bloomberg and Reuters. The NAV per Share will be calculated daily and 
made available to all market participants at the same time. The Trust 
will provide website disclosure of its NAV daily. One or more major 
market data vendors will disseminate for the Trust on a daily basis 
information with respect to the most recent NAV per Share and Shares 
outstanding. In addition, if the Exchange becomes aware that the NAV 
per Share is not disseminated to all market participants at the same 
time, it will halt trading in the Shares until such time as the NAV is 
available to all market participants. Quotation and last-sale 
information regarding the Shares will be disseminated through the

[[Page 10980]]

facilities of the CTA. The IIV will be widely disseminated on a per 
Share basis every 15 seconds during the NYSE Arca Core Trading Session 
(normally 9:30 a.m., E.T., to 4:00 p.m., E.T.) by one or more major 
market data vendors. The Exchange represents that the Exchange may halt 
trading during the day in which an interruption to the dissemination of 
the IIV or the value of the Index occurs. If the interruption to the 
dissemination of the IIV or the value of the Index persists past the 
trading day in which it occurred, the Exchange will halt trading no 
later than the beginning of the trading day following the interruption.
    The proposed rule change is designed to perfect the mechanism of a 
free and open market and, in general, to protect investors and the 
public interest in that it will facilitate the listing and trading of 
an additional type of exchange-traded product that will enhance 
competition among market participants, to the benefit of investors and 
the marketplace. As noted above, the Exchange has in place surveillance 
procedures relating to trading in the Shares on the Exchange and may 
obtain information via ISG from other exchanges that are members of ISG 
or with which the Exchange has entered into a CSSA. In addition, as 
noted above, investors will have ready access to information regarding 
the Trust's NAV, IIV, and quotation and last sale information for the 
Shares.

B. Self-Regulatory Organization's Statement on Burden on Competition

    The Exchange does not believe that the proposed rule change will 
impose any burden on competition that is not necessary or appropriate 
in furtherance of the purposes of the Act. The Exchange notes that the 
proposed rule change will facilitate the listing and trading of an 
additional type of exchange-traded product, and the first such product 
based on ADA, which will enhance competition among market participants, 
to the benefit of investors and the marketplace.

C. Self-Regulatory Organization's Statement on Comments on the Proposed 
Rule Change Received From Members, Participants, or Others

    No written comments were solicited or received with respect to the 
proposed rule change.
