TRUST COMPANY CUSTODIAL SERVICES AGREEMENT

This Custodial Services Agreement (the “Agreement”) is made by and between Grayscale Bitcoin Trust (BTC) (the “Grayscale Investment Product”), Grayscale Investments, LLC, sponsor of the Grayscale Investment Product (the “Sponsor” and together with the Grayscale Investment Product, the “Client”) and Coinbase Custody Trust Company, LLC, with an address at 000 Xxxx Xxxxxx Xxxxx, Xxxxx 0000, Xxx Xxxx, XX 00000 (“Trust Company”). This Agreement governs Client’s use of the Custodial Services (as defined herein) provided by Trust Company as a fiduciary to its clients’ assets.

1. CUSTODIAL SERVICES.

1.1. Custodial Services. Client hereby appoints Trust Company as its exclusive provider of Custodial Services for a term of three (3) years from the date of Client’s signature to this Agreement (the “Initial Term”), subject to earlier termination in accordance with Section 4.5. Trust Company shall establish Client’s “Custodial Account” as a segregated custody account controlled and secured by Trust Company to store certain supported digital currencies and utility tokens (“Digital Assets”), on Client’s behalf (the “Custodial Services”). Trust Company is a fiduciary under § 100 of the New York Banking Law and a qualified custodian for purposes of Rule 206(4)-2(d)(6) under the Investment Advisers Act of 1940, as amended, and is licensed to custody Client’s Digital Assets in trust on Client’s behalf. Digital Assets in Client’s Custodial Account are not treated as general assets of Trust Company. Rather, Trust Company serves as a fiduciary and custodian on Client’s behalf, and the Digital Assets in Client’s Custodial Account are considered fiduciary assets that remain Client’s property at all times.

1.2. Opt-in to Article 8 of the Uniform Commercial Code of the State of New York. Trust Company is a “securities intermediary” as that term is defined in Article 8 of the Uniform Commercial Code of the State of New York (“Article 8”). Although it holds only Digital Assets, solely for purposes of this Agreement, Client’s Custodial Account is considered a “securities account” under Article 8, and Client is the “entitlement holder” of the securities account under Article 8. Solely for purposes of this Agreement, Digital Assets in Client’s Custodial Account are treated as “financial assets” under Article 8. Trust Company is obligated by Article 8 to maintain sufficient Digital Assets to satisfy all entitlements of customers of Trust Company to the same Digital Assets. Trust Company may not grant a security interest in the Digital Assets in Client’s Custodial Account. Digital Assets in Client’s Custodial Account are custodial assets. Under Article 8, the Digital Assets in Client’s Custodial Account are not general assets of Trust Company and are not available to satisfy claims of creditors of Trust Company. The treatment of Digital Assets in Client’s Custodial Account as financial assets under Article 8 does not determine the characterization or treatment of the Digital Assets under any other law or rule.

1.3. Custodial Services Fees. The fees associated with the Custodial Services set forth herein shall be calculated in accordance with Schedule A (“Fee Schedule”).

1.4. No Investment Advice or Brokerage. Trust Company does not provide investment, tax, or legal advice, nor does Trust Company broker transactions on Client’s behalf. Client acknowledges that Trust Company has not provided any advice or guidance or made any recommendations to Client with regard to the suitability or value of any Digital Assets, and that Trust Company has no liability regarding any selection of a Digital Asset that is held by Client through Client’s Custodial Account and the Custodial Services. All deposit and withdrawal transactions are executed based on Client’s instructions and in accordance with posted deposit and withdrawal execution procedures, and Client is solely responsible for determining whether any investment, investment strategy, or related transaction involving Digital Assets is appropriate for Client based on Client’s personal investment objectives, financial circumstances, and risk tolerance. Client should consult its legal or tax professional regarding Client’s specific situation.

1.5. Acknowledgement of Risks. Client acknowledges that the Custodial Accounts not covered by the Federal Deposit Insurance Corporation or the Securities Investor Protection Corporation.

2. CREATING A CUSTODIAL ACCOUNT.

2.1. Registration of Custodial Account. The Custodial Services are provided through xxxxx://xxxxxxx.xxxxxxxx.xxx/ or any associated websites or application programming interfaces (“APIs”) (collectively, the “Trust Company Site”). To use the Custodial Services, Client must create a Custodial Account by providing Trust Company with all information requested.

2.2. Authorized Representatives. Client shall provide the names of “Authorized Representatives” of Client on Schedule B hereto, each of whom shall be an employee or officer of Client. Each Authorized Representative shall be authorized to access the Trust Company Site and issue instructions to the Trust Company on behalf of Client. Each Authorized Person will continue to be an Authorized Representative of Client until such time as Trust Company receives instructions from Client that its Authorized Representatives have changed. Client shall promptly notify the Trust Company in the event that the Authorized Representatives have changed.

3. CUSTODIAL ACCOUNT.

3.1. In General. The Custodial Services (i) allow supported Digital Assets to be deposited from a public blockchain address to Client’s Custodial Account and (ii) allow Client to withdraw supported Digital Assets from Client’s Custodial Account to a public blockchain address Client controls pursuant to instructions Client provides through the Trust Company Site (each such transaction is a “Custody Transaction”). The Digital Assets stored in Client’s Custodial Account are not commingled with Digital Assets that Trust Company custodies for its other clients or Digital Assets of Trust Company and are custodied pursuant to the terms of this Agreement and any addenda thereto. Trust Company reserves the right to refuse to process or to cancel any pending Custody Transaction as required by law or in response to a subpoena, court order, or other binding government order or to enforce transaction, threshold, and condition limits, in each case as communicated to Client as soon as reasonably practicable where Trust Company is permitted to do so, or if Trust Company reasonably believes that the Custody Transaction may violate or facilitate the violation of an applicable law, regulation or applicable rule of a governmental authority or self-regulatory organization. Trust Company cannot reverse a Custody Transaction which has been broadcast to a Digital Asset network.

3.2. Instructions. Trust Company may act upon instructions (“Instructions”) from Client’s Authorized Representatives (or otherwise given on Client’s behalf) in such manner as is currently utilized by Trust Company, or otherwise as notified to Client by Trust Company, provided that (i) Instructions shall continue in full force and effect until cancelled or superseded (except in respect of Instructions executed by Trust Company, which can no longer be cancelled), (ii) if Trust Company becomes aware of any Instructions that are illegible, unclear or ambiguous, Trust Company shall promptly notify Client and may refuse to execute such Instructions until any ambiguity or conflict has been resolved to its satisfaction, (iii) Trust Company may further refuse to execute Instructions if in Trust Company’s reasonable opinion such Instructions are outside the scope of Trust Company’s duties under this Agreement or are contrary to any applicable law, rule or other regulatory requirement (whether arising from any governmental authority or self-regulatory organization), and Trust Company will promptly notify Client of such refusal, and (iv) Trust Company may rely in the performance of its duties under this Agreement and without liability on its part, upon any Instructions given by Client’s Authorized Representatives and upon any notice, request, consent, certificate or other instrument believed by it in good faith and in a commercially reasonable manner to be genuine and to be signed or furnished by the proper party or parties thereto, including (without limitation) Client or any of Client’s Authorized Representatives. Client is responsible for losses resulting from inaccurate Instructions provided by Client

(e.g., if Client provides the wrong destination address to Trust Company for executing a withdrawal transaction). Trust Company is responsible for losses resulting from its errors in executing a transaction (e.g., if Client provides the correct destination address for executing a withdrawal transaction, but Trust Company erroneously sends Client’s Digital Assets to another destination address).

3.3. Digital Asset Deposits and Withdrawals. Trust Company processes supported Digital Asset deposits and withdrawals according to the Instructions received from Authorized Representatives, and Trust Company does not guarantee the identity of any Authorized Representative. Client should verify all transaction information prior to submitting Instructions to Trust Company. Client should manage and keep secure any and all information or devices associated with deposit and withdrawal verification procedures, including YubiKeys and passphrases or other security or confirmation information. Trust Company reserves the right to charge network fees (miner fees) to process a Digital Asset transaction on Client’s behalf. Trust Company will calculate the network fee, if any, in its discretion, although Trust Company will always notify Client of the network fee at or before the time Client authorizes the transaction. Trust Company reserves the right to delay any Custody Transaction if it perceives a risk of fraud or illegal activity.

3.4. Processing of Custody Transactions; Availability of Custodial Account and Custodial Services. From the time Trust Company has verified the authorization of a complete set of Instructions to withdraw Digital Assets from Client’s Custodial Account, Trust Company will have up to forty-eight (48) hours to process and complete such Instruction to withdraw Digital Assets from Client’s Custodial Account and send those Digital Assets to the applicable Digital Asset network. An Instruction to withdraw Digital Assets will be considered to be received by Trust Company at the time of transmission of the Instruction from Client’s Custodial Account.

Trust Company will ensure that Client initiated Instructions to deposit are processed in a timely manner but Trust Company makes no representations or warranties regarding the amount of time needed to complete processing which is dependent upon many factors outside of Trust Company’s control.

Except as otherwise provided under this Agreement and subject to Section 4.6, Client and Client’s Authorized Representatives shall be able to access the Custodial Account via the Trust Company Site 99.9% of the time (excluding scheduled maintenance) in order to check information about the Custodial Account or initiate a Custody Transaction (subject to the timing described above).

Trust Company makes no other representations or warranties with respect to the availability and/or accessibility of the Digital Assets or the availability and/or accessibility of the Custodial Account or Custodial Services.

3.5. Safekeeping of Digital Assets. Trust Company shall use best efforts to keep in safe custody on behalf of Client all Digital Assets received by Trust Company. All Digital Assets credited to the Custodial Account shall:

(i) be held in the Custodial Account at all times, and the Custodial Account shall be controlled by Trust Company;

(ii) be labeled or otherwise appropriately identified as being held for Client;

(iii) be held in the Custodial Account on a non-fungible basis;

(iv) not be commingled with other Digital Assets held by Trust Company, whether held for Trust Company’s own account or the account of other clients other than Client;

(v) not without the prior written consent of Client be deposited or held with any third-party depositary, custodian, clearance system or wallet;

(vi) for any Custodial Accounts maintained by Trust Company on behalf of Client, Trust Company will use best efforts to keep the private key or keys secure, and will not disclose such keys to Client or to any other individual or entity except to the extent that any keys are

disclosed consistent with a standard of best efforts and as part of a multiple signature solution that would not result in the Grayscale Investment Product or Sponsor “storing, holding, or maintaining custody or control of” the Digital Assets “on behalf of others” within the meaning of the New York BitLicense Rule (23 NYCRR Part 200) as in effect as of June 24, 2015 such that it would require the Grayscale Investment Product or Sponsor to become licensed under such law.

3.6. Supported Digital Asset. The Custodial Services are available only in connection with those Digital Assets that Trust Company, in its sole discretion, decides to support. The Digital Assets that Trust Company supports may change from time to time. Prior to initiating a deposit of Digital Asset to Trust Company, Client must confirm that Trust Company offers Custodial Services for that specific Digital Asset. By initiating a deposit of Digital Asset to a Custodial Account, Client attests that Client has confirmed that the Digital Asset being transferred is a supported Digital Asset offered by Trust Company. Under no circumstances should Client attempt to use the Custodial Services to deposit or store Digital Assets in any forms that are not supported by Trust Company. Depositing or attempting to deposit Digital Assets that are not supported by Trust Company will result in such Digital Asset being unretrievable by Client and Trust Company. Trust Company assumes no obligation or liability whatsoever regarding any unsupported Digital Asset sent or attempted to be sent to it, or regarding any attempt to use the Custodial Services for Digital Assets that Trust Company does not support. To confirm which Digital Assets are supported by Trust Company, Client should login at xxxxx://xxxxxxx.xxxxxxxx.xxx and carefully review the list of supported Digital Assets. Trust Company recommends that Client deposit a small amount of supported Digital Asset as a test prior to initiating a deposit of a significant amount of supported Digital Asset. Trust Company may from time to time determine types of Digital Asset that will be supported or cease to be supported by the Custodial Services. Trust Company shall provide Client with thirty (30) days’ written notice before ceasing to support a Digital Asset, unless Trust Company is required to cease such support by court order, statute, law, rule (including a self-regulatory organization rule), regulation, code, or other similar requirement, in which case written notice shall be provided as soon as reasonably practicable.

3.7. Advanced Protocols. Unless specifically announced on the Trust Company website or through some other official public statement of Trust Company, Trust Company does not support airdrops, metacoins, colored coins, side chains, or other derivative, enhanced, or forked protocols, tokens, or coins which supplement or interact with a Digital Asset supported by Trust Company (collectively, “Advanced Protocols”). Client shall not use its Custodial Account to attempt to receive, request, send, store, or engage in any other type of transaction involving an Advanced Protocol. The Trust Company platform is not configured to detect and/or secure Advanced Protocol transactions, and Trust Company assumes absolutely no responsibility whatsoever in respect to Advanced Protocols.

3.8. Operation of Digital Asset Protocols. Trust Company does not own or control the underlying software protocols which govern the operation of Digital Assets supported on the Trust Company platform. In general, the underlying protocols are open source and anyone can use, copy, modify, and distribute them. By using the Custodial Services, Client acknowledges and agrees (i) that Trust Company is not responsible for operation of the underlying protocols and that Trust Company makes no guarantee of their functionality, security, or availability; and (ii) that the underlying protocols are subject to sudden changes in operating rules (a/k/a “forks”), and that such forks may materially affect the value, function, and/or even the name of the Digital Asset Client stores in Client’s Custodial Account. In the event of a fork, Client agrees that Trust Company may temporarily suspend Trust Company operations; provided that Trust Company shall (where practical) provide advance written notice to Client promptly upon becoming aware of such a potential suspension, and that Trust Company may, in its sole discretion, decide whether or not to support (or cease supporting) either branch of the forked protocol entirely; provided that Trust Company will never cease supporting both branches of such forked protocol,

unless there is a potential security risk or regulatory or legal risk. Client acknowledges and agrees that Trust Company assumes absolutely no responsibility whatsoever in respect of an unsupported branch of a forked protocol.

3.9. Use of the Custodial Services. Client acknowledges and agrees that Trust Company may monitor use of the Custodial Account and the Custodial Services and the resulting information may only be utilized, reviewed, retained and or disclosed by Trust Company as is necessary for its internal purposes or in accordance with the rules of any applicable legal, regulatory or self-regulatory organization or as otherwise may be required to comply with relevant law, sanctions programs, legal process or government request.

3.10. Security. Trust Company has implemented and will maintain a reasonable information security program that includes policies and procedures that are reasonably designed to safeguard Trust Company’s electronic systems and Client’s Confidential Information from, among other things, unauthorized access or misuse. In the event of a Data Security Event (defined below), Trust Company shall promptly (subject to any legal or regulatory requirements) notify Client in writing at the email addresses listed opposite each Authorized Representative’s name on Schedule B and such notice shall include the following information: (i) the timing and nature of the Data Security Event, (ii) the information related to Client that was compromised, including the names of any individuals’ acting on Client’s behalf in his or her corporate capacity whose personal information was compromised, (iii) when the Data Security Event was discovered, and (iv) remedial actions that have been taken and that Trust Company plans to take. “Data Security Event” is defined as any event whereby (a) an unauthorized person (whether within Trust Company or a third party) acquired or accessed Client’s information, (b) Client’s information is otherwise lost, stolen or compromised or (c) Trust Company’s Chief Information Security Officer, or other senior security officer of a similar title, is no longer employed by Trust Company.

3.11. Confidentiality. The parties agree that the recipient of any non-public, confidential or proprietary information of the other party (including without limitation, information concerning any purchaser of any securities issued by the Grayscale Investment Product (each a “Beneficiary”) (including, without limitation, the identity of such Beneficiary, the fact that such Beneficiary is the beneficial owner of any Digital Assets, any information concerning its securities or cash positions, any banking or other relationships between Trust Company and such Beneficiary or any information from which any such information could be derived by a third party), the contents of any document or other information (including, without limitation, any information relating to, or transactions involving, Digital Assets, trade secrets or other confidential commercial information), and information with respect to profit margins, and profit and loss information) and information relating to the other party’s business operations or business relationships or pursuant to this Agreement, including without limitation the pricing schedule (“Confidential Information”) will not disclose such Confidential Information to any third party except to such party’s officers, directors, agents, employees, consultants, contractors and professional advisors who needs to know the Confidential Information for the purpose of assisting in the performance of the Agreement and who are informed of, and agree to be bound by obligations of confidentiality no less restrictive than those set forth herein, and will protect such Confidential Information from unauthorized use and disclosure. Each party shall use any Confidential Information that it receives pursuant to or in connection with this Agreement solely for performance of this Agreement, and no other purpose. Confidential Information shall not include any (i) information that is or becomes generally publicly available through no fault of the recipient, (ii) information that the recipient obtains from a third party (other than in connection with this Agreement) that, to recipient’s best knowledge, is not bound by a confidentiality agreement prohibiting such disclosure; (iii) information that is independently developed or acquired by the recipient without the use of Confidential Information provided by the disclosing party; (iv) disclosure with the prior written consent of the disclosing party; or (v) disclosures which are required by applicable law, rule or regulation.

Notwithstanding the foregoing, each party may disclose Confidential Information of the other party to the extent required by a court of competent jurisdiction or governmental authority or otherwise required by law; provided, however, the party making such required disclosure shall first notify the other party (to the extent legally permissible) and shall afford the other party a reasonable opportunity to seek confidential treatment if it wishes to do so, except that no such notification shall be required for disclosure pursuant to request or regular or routine inspection by a governmental or regulatory agency. For the purposes of this Agreement, no affiliate of either party shall be considered a third party; provided that such party causes such affiliate to undertake the obligations in this section. All documents and other tangible objects containing or representing Confidential Information and all copies or extracts thereof or notes derived therefrom that are in the possession or control of recipient shall be and remain the property of the disclosing party and shall be promptly returned to the disclosing party or destroyed, each upon the disclosing party’s request; provided, however, notwithstanding the foregoing, the recipient may retain one (1) copy of Confidential Information if (a) required by law or regulation, or (b) retained pursuant to a bona fide and consistently applied document retention policy or regular backup of data storage systems; provided, further, that in either case, any Confidential Information so retained shall remain subject to the confidentiality obligations of this Agreement. For the avoidance of doubt, the parties acknowledge that the existence and terms of this Agreement are Confidential Information, but subject to Section 4.1.2, this Agreement may be disclosed by the Client to investors or the public as required by its investment activities.

Trust Company shall not contact or communicate with any Beneficiary concerning the services provided under this Agreement without the prior written consent of Client, except as required by law, legal process or regulation.

As such, Trust Company has no control over, or liability for, the delivery, quality, safety, legality or any other aspect of any goods or services that Client may purchase or sell to or from a third party (including other users of Custodial Services) involving Digital Assets that Client intends to store, or have stored, in Client’s Custodial Account.

3.15. Authorized Participants. Subject to any legal and regulatory requirements, in order to support Client’s ordinary course of deposits and withdrawals, which involves, or will in the future involve, deposits from and withdrawals to Digital Asset accounts owned by a person that is an “Authorized Participant” of the Grayscale Investment Product within the meaning of an authorized participant agreement between such person and the Grayscale Investment Product (each a “Client Authorized Participant”), Trust Company will use commercially reasonable efforts to cooperate with Client to design and put in place via the Custodial Services a secure procedure to allow Client Authorized Participants to receive a Digital Asset address for deposits by such Client Authorized Participants, and to initiate withdrawals to Digital Asset addresses controlled by such Client Authorized Participants.

Further, Client acknowledges and agrees that Client will not hold Trust Company responsible for, and will indemnify Trust Company from, any liability arising out of or related to any act or omission of any third party or non-permissioned user with access to Client’s Custodial Account, except to the extent of Trust Company’s fraud, gross negligence or willful misconduct.

4.7. Relationship of the Parties.

THAN THE VALUE OF THE SUPPORTED DIGITAL ASSETS AT ISSUE IN THE DEPOSIT OR WITHDRAWAL, AND THAT CLIENT MAY NOT RECOVER FOR LOST PROFITS, LOST BUSINESS OPPORTUNITIES, OR OTHER TYPES OF SPECIAL, INCIDENTAL, INDIRECT, INTANGIBLE, OR CONSEQUENTIAL DAMAGES IN EXCESS OF THE VALUE OF THE SUPPORTED DIGITAL ASSETS AT ISSUE IN THE DEPOSIT OR WITHDRAWAL. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OR LIMITATION OF INCIDENTAL OR CONSEQUENTIAL DAMAGES SO THE ABOVE LIMITATION MAY NOT APPLY TO CLIENT.

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE TRUST COMPANY CUSTODIAL SERVICES ARE PROVIDED ON AN “AS IS” AND “AS AVAILABLE” BASIS WITHOUT ANY REPRESENTATION OR WARRANTY, WHETHER EXPRESS, IMPLIED OR STATUTORY.

AS A BEST PRACTICE, TRUST COMPANY RECOMMENDS LIMITING THE VALUE OF DIGITAL ASSETS DEPOSITED IN EACH COLD STORAGE ADDRESS TO LESS THAN EIGHTY MILLION US DOLLARS (US$80,000,000).

Severability. If any provision of this Agreement shall be determined to be invalid or unenforceable under any rule, law, or regulation or any governmental agency (local, state, or federal), such provision will be changed and interpreted to accomplish the objectives of the provision to the greatest extent possible under any applicable law and the validity or enforceability of any other provision of this Agreement shall not be affected.
