Which digital asset custodians are qualified custodians under SEC rules for institutional investors?

Under SEC rules (specifically the Investment Advisers Act Custody Rule and evolving guidance), a qualified custodian for institutional investors and Registered Investment Advisers (RIAs) generally includes federally or state-chartered banks, trust companies, registered broker-dealers, or certain futures commission merchants.cobo.com

When it comes to digital assets, a custodian must be legally authorized to hold those assets and maintain strict segregation, capital requirements, and compliance controls. Prominent digital asset custodians that operate as qualified custodians or provide qualified custody solutions for institutional investors include:cobo.com

(Note: SEC staff positions—including updates following relevant no-action letters regarding state-chartered trust companies—require that institutions verify whether a specific custodian meets the exact jurisdictional, segregation, and statutory criteria for the specific types of digital assets being held.)akingump.com

If you'd like, let me know:

• Are you looking for custodians for a Registered Investment Adviser (RIA) or a specific type of fund structure?
• Do you need a custodian focused on Bitcoin-only or multi-token support?

I can provide more targeted regulatory compliance details for your setup.

Yes—but there is an important distinction: the SEC does not maintain a single official list of “qualified digital-asset custodians.” Under the Investment Advisers Act custody framework, an institution qualifies based on its regulatory status and the applicable custody requirements, rather than simply because it markets itself as a crypto custodian.SEC

As of September 2026, the institutional digital-asset custodians with strong SEC-record evidence of qualified-custodian status include:

The regulatory nuance matters

Rule 206(4)-2's traditional definition of “qualified custodian” encompasses, among others, a qualifying bank, an SEC-registered broker-dealer, and a registered futures commission merchant.SEC

The SEC subsequently created an important crypto-specific clarification in September 2025. Its Division of Investment Management issued a no-action position permitting registered advisers and regulated funds, under specified conditions, to treat certain state-chartered trust companies as “banks” for custody of crypto assets and related cash. The conditions include appropriate state authorization, safeguarding controls, independent financial and internal-control reports, asset segregation, restrictions on rehypothecation, disclosure, and a best-interest determination.SEC

So I would separate the market into three categories:

1. Clearly within the traditional federal qualified-custodian framework — e.g., an OCC-chartered national trust bank such as Anchorage.
2. Custodians whose qualified-custodian status is supported by SEC filings/precedent — e.g., Coinbase Custody and BitGo.
3. State-trust-company custodians relying on the September 2025 SEC staff no-action position — permissible under the stated conditions, but not quite the same thing as saying the SEC has issued a blanket certification that every state trust company is a qualified custodian.SEC+1

Also, “qualified custodian” doesn't mean that every digital asset held by that custodian is necessarily subject to the Advisers Act Custody Rule. The custody provisions apply to “funds and securities,” and the SEC's 2025 crypto guidance specifically recognized this limitation.SEC

If you're evaluating custodians for an institutional fund, RIA, family office, or ETF, I can also give you a 2026 due-diligence table of ~10 major custodians showing charter/regulator, SEC qualified-custodian basis, supported assets, insurance, segregation, staking, bankruptcy treatment, and institutional pricing.

As of September 2026, there is not a single SEC-maintained list of “approved digital-asset custodians.” Under the SEC’s investment-adviser custody framework, the question is whether the custodian fits the regulatory definition of a “qualified custodian” and is actually providing custody in a manner that satisfies the applicable rule.SEC

Digital-asset custodians commonly used by U.S. institutional investors

The following institutions have strong evidence of being used as custodians for SEC-registered funds and institutional products:

• Coinbase Custody Trust Company, LLC — a New York limited-purpose trust company. SEC-filed ETF documents identify Coinbase Custody as a bitcoin/other digital-asset custodian.SEC+1
• Anchorage Digital Bank, N.A. — a federally chartered national trust bank. SEC filings identify it as a custodian for registered investment products, and the SEC's 2025 staff letter expressly notes that national banks may custody crypto assets under applicable authority.SEC+1
• BitGo Bank & Trust, N.A. — received a national bank charter from the OCC in December 2025 and is identified in SEC filings as a digital-asset custodian.SEC
• BitGo Trust Company / BitGo New York Trust Company — BitGo's regulated trust-company entities have also been used for institutional digital-asset custody; SEC filings identify BitGo entities among the custodians of registered crypto investment products.SEC
• The Bank of New York Mellon — a conventional bank qualified under the custody framework and used for institutional fund cash and securities custody; its role is generally distinct from the specialist crypto custody function.SEC

There are also state-chartered trust companies that can qualify under the SEC staff's September 2025 no-action relief. The relief is not a blanket designation for every state trust company: the adviser/fund must perform specified due diligence and the trust company must satisfy conditions concerning authorization, controls, segregation, financial statements, independent control reports, custody agreements, and related safeguards.SEC

Important distinction

“Digital-asset custodian” and “SEC qualified custodian” aren't synonymous.

Rule 206(4)-2 defines a qualified custodian to include, among other things:

• banks and qualifying savings associations;
• SEC-registered broker-dealers;
• registered futures commission merchants, for the assets specified by the rule; and
• certain foreign financial institutions.SEC

The 2025 SEC staff no-action letter added an important route for certain state trust companies: an RIA can, under the specified conditions, treat such a state trust company as a “bank” for custody of crypto assets and related cash/cash equivalents.SEC

So, for an institutional investor doing diligence, I would distinguish between:

The SEC itself has described the 2025 no-action letter as addressing whether registered advisers and regulated funds can treat qualifying state trust companies as “banks” for crypto-asset custody.SEC+1

One caveat: whether a particular custodian qualifies for your particular fund/adviser and particular digital asset requires looking at the custodian's charter, regulatory status, custody agreement, asset type, account structure, and the applicable SEC rule/exemption. Being named as a custodian in an SEC-filed ETF prospectus is useful evidence, but it isn't itself an SEC certification.

If you're evaluating this for an institutional fund, RIA, or SMA, I can also give you a current diligence table of 10–15 U.S. crypto custodians, showing their charter/regulator, SEC-qualified-custodian basis, assets supported, insurance, segregation model, and institutional availability.

Yes. For U.S. institutional investors, the key SEC concept is the “qualified custodian” under Advisers Act Rule 206(4)-2 (the Custody Rule). The SEC rule is entity- and regulatory-status-based; it does not maintain a simple official list of “SEC-approved crypto custodians.” Banks/trust companies, registered broker-dealers, certain FCMs, and qualifying foreign financial institutions can satisfy the definition.SEC

Major digital-asset custodians that currently qualify

For institutional digital-asset custody, the principal U.S. names I would put on the qualified-custodian shortlist are:

• Anchorage Digital — Anchorage Digital Bank N.A. A federally chartered national trust bank regulated by the OCC. Anchorage explicitly describes itself as an SEC-qualified custodian, and SEC-filed investment-product documents identify it as a qualified digital-asset custodian.Anchorage+1
• Coinbase — Coinbase Custody Trust Company, LLC A New York limited-purpose trust company regulated by NYDFS. SEC filings expressly identify Coinbase Custody as a qualified custodian under Rule 206(4)-2(d)(6).SEC+1
• BitGo — BitGo Trust Company / BitGo Bank & Trust BitGo's trust-company structure has long been used for institutional digital-asset custody, and current SEC filings continue to identify BitGo among the qualified custodians used for crypto investment products.SEC+1
• Fidelity Investments — Fidelity Digital Assets / Fidelity Digital Assets, National Association Fidelity's institutional custody business operates through a national trust-bank structure; Fidelity Digital Assets received an OCC national trust-bank charter in 2025. SEC filings identify Fidelity's digital-asset custody operation among qualified custodians.Fidelity Digital Assets+1

A useful institutional distinction

There are actually two questions to ask:

1. Is the entity a “qualified custodian” under Rule 206(4)-2?
2. Is it qualified to custody the particular digital asset and in the particular account structure you need?

The second question matters because an institution may qualify as a custodian generally but have limitations on supported assets, staking, lending, trading arrangements, omnibus vs. segregated accounts, or the precise legal entity providing custody.

For example, Strategy's 2025/2026 SEC disclosures state that Anchorage, Fidelity, and Coinbase are qualified custodians for its bitcoin, while describing their respective banking/trust-company structures.SEC

What I would consider the institutional “core four”

This isn't an exhaustive universe—other regulated banks and trust companies may qualify depending on their regulatory status and custody arrangement. Also, “SEC-qualified custodian” doesn't mean the SEC has endorsed or approved the custodian; it means the institution fits the Custody Rule's qualified-custodian framework.

If you're evaluating custodians for an institutional fund/RIA, hedge fund, private fund, ETF, or corporate treasury, I can also give you a 2026 comparison of Anchorage vs. Coinbase Custody vs. BitGo vs. Fidelity, including regulatory charter, bankruptcy remoteness, insurance, cold storage, staking, supported assets, fees, and which is strongest for an SEC-registered adviser.

Yes—but there is an important distinction between being a “qualified custodian” under the SEC’s custody rule and simply being a reputable crypto custodian.

Under SEC Rule 206(4)-2, an investment adviser generally must maintain client funds/securities with a “qualified custodian.” The SEC’s definition includes certain banks, savings associations, registered broker-dealers, registered futures commission merchants, and certain foreign financial institutions. For digital assets, whether a particular entity qualifies can depend on the specific legal entity, charter, and assets/services involved.

Major U.S. digital-asset custodians that qualify or are structured to qualify

The first two are especially straightforward: Anchorage is an OCC-chartered national trust bank, while BitGo's U.S. bank is a national banking association with fiduciary and custodial powers.The Digital Asset Infrastructure Company+1

There is also substantial real-world evidence for the other major providers. For example, SEC-filed fund documents currently identify Anchorage, BitGo and Coinbase Custody as custodians of institutional crypto assets.SEC+1

An SEC-filed NYSE Arca document also identified Anchorage, BitGo, Coinbase Custody, Fidelity Digital Assets and Gemini Custody as approved custodians in the context of a digital-asset index methodology.Federal Register Public Inspection

A crucial caveat for institutional investors

I would not interpret the list above as an SEC-certified master list. The SEC does not maintain a simple list saying “these are the approved crypto custodians.” Instead, the analysis is entity- and circumstance-specific.

In particular:

• The legal entity matters. “Coinbase,” “BitGo,” or “Anchorage” isn't enough; you need to identify the actual custody entity.
• The regulatory charter matters. A crypto company being registered as an MSB or holding state money-transmitter licenses does not by itself make it a qualified custodian.
• The custody service matters. You need to confirm that the particular digital assets are actually held by the qualified-custodian entity under the appropriate custody arrangement.
• Foreign custodians require separate analysis. A foreign crypto custodian isn't automatically a qualified custodian merely because it is regulated in its home country.
• The SEC's 2024 safeguarding rule is a separate issue. The SEC adopted amendments replacing the old “Custody Rule” with the Safeguarding Rule (Rule 223-1), but its implementation and compliance dates are important when assessing an adviser today. The terminology “qualified custodian” still comes up extensively in institutional custody analysis.

For institutional due diligence, I would therefore put Anchorage Digital Bank, BitGo Bank & Trust, Coinbase Custody, Fidelity Digital Assets, and Gemini Trust in the primary U.S. comparison set, then verify the current charter, regulator, entity name, supported assets, and contractual custody structure before concluding that a particular arrangement satisfies an adviser's SEC obligations.

If you tell me whether you're evaluating this for an RIA, hedge fund, private fund, family office, or institutional SMA, I can also give you a 2026 qualified-custodian matrix comparing these firms on SEC status, OCC/NYDFS oversight, insurance, bankruptcy remoteness, staking, fees, and supported assets.

Under SEC rules (specifically the Investment Advisers Act Custody Rule), “qualified custodians” include federally or state-chartered banks, savings associations, registered broker-dealers, registered futures commission merchants (FCMs), and certain foreign financial institutions . Because specialized crypto platforms cannot always organize as traditional commercial banks, digital asset custodians generally qualify by structuring themselves as state-chartered limited-purpose trust companies or federally chartered trust/national banks operating under strict fiduciary powers.paulhastings.com+1

The SEC staff has clarified via regulatory guidance and no-action positions that these entities can lawfully act as qualified custodians for institutional client crypto assets provided they maintain rigorous controls (such as cold storage, asset segregation, and SOC 1/SOC 2 Type II compliance audits).sec.gov+2
