Tokenized real-world asset custody in 2026 is dominated by five institutional providers: Anchorage Digital Bank, BitGo Trust, Fireblocks, Coinbase Custody, and Komainu. Each operates under a different regulatory wrapper, supports a different mix of tokenized funds, and prices security differently. Tokenized fund AUM crossed $20B in early 2026 per rwa.xyz, and most of it sits with one of these five.
​

This guide compares the five against the criteria that matter for tokenized funds: qualified-custodian status under SEC Rule 206(4)-2, supported tokenized fund tickers (BUIDL, OUSG, BENJI, USTB, USYC), insurance coverage, and onchain-key architecture.
​

Tokenized RWA custody is the safekeeping of blockchain-native representations of off-chain assets, including tokenized money market funds and treasuries, by a regulated third party. The custodian holds private keys, settles transfers, and produces statements suitable for fund administrators and auditors. It blends classical securities custody duties with onchain key management.
​

The legal anchor is the SEC's "qualified custodian" standard under Rule 206(4)-2 of the Investment Advisers Act. Registered investment advisers must hold client securities with a bank, broker-dealer, FCM, or foreign financial institution that qualifies. Fund issuers Securitize, Ondo, Franklin Templeton, and Superstate route their tokenized fund subscriptions through custodians that meet this bar. See the SEC's 2017 staff guidance for how digital assets fit the framework.
​

Custody matters because tokenized funds settle ownership through onchain transfers, but the underlying securities remain offchain at a transfer agent or fund administrator. A custody breach risks the token, the fund interest, or both. Registered investment advisers are legally required to use a qualified custodian, so the choice gates access for most institutional allocators.
​

BlackRock's BUIDL uses Securitize as transfer agent and a panel of bank-grade custodians for token-level safekeeping. Ondo's OUSG structure tokenizes shares of a fund held by State Street and BlackRock-administered vehicles. Franklin Templeton's BENJI runs on Franklin's proprietary transfer agent. Without a qualified custodian wrapping these tokens for the end investor, the chain of compliance breaks.
​

Anchorage Digital Bank is the only federally chartered crypto bank in the United States, holding a national trust charter from the Office of the Comptroller of the Currency since January 2021. It custodies tokenized money market funds for institutional clients, supports BUIDL and OUSG transfers, and operates segregated onchain accounts with multi-party hardware key management.
​

The OCC charter, granted on January 13, 2021, makes Anchorage a national bank for federal banking purposes. The federal charter is operationally important because it preempts the state-by-state money transmitter licensing patchwork that other US custodians navigate. Anchorage publishes a current asset list at anchorage.com/assets and includes BUIDL and OUSG among supported tokenized funds.
​

Anchorage's key architecture uses biometric quorum approval, hardware security modules co-developed with a third-party vendor, and segregated wallet addresses per client. Withdrawal policies are programmable: clients can require multiple human approvers, geographic dispersion, and time delays before any movement. Insurance coverage layers through Lloyd's syndicates and undisclosed primary carriers, with limits disclosed under NDA to qualifying institutional counterparties per the firm's custody product page. Anchorage also acts as a sub-custodian for several large asset managers entering the tokenized fund market.
​

BitGo Trust Company is a South Dakota-chartered trust company and a qualified custodian under SEC Rule 206(4)-2. It supports more than 1,100 onchain assets, custodies BUIDL and OUSG, and operates BitGo Trust as a regulated entity distinct from the BitGo software platform. BitGo's hot, warm, and cold wallet architecture uses BLS multi-signature and threshold signing.
​

BitGo Trust holds charters in South Dakota, New York (BitGo NY Trust), and Germany (BitGo Europe). Per the firm's custody page, BitGo carries a $250M insurance policy through Lloyd's of London covering custodied assets. The platform integrates with Securitize for tokenized fund subscriptions and supports OUSG transfers natively. BitGo Trust acts as the qualified custodian of record for several tokenized fund issuers, including Hashnote's USYC distribution.
​

BitGo's wallet architecture splits keys across three independent parties: BitGo, the client, and an optional backup key holder. Recovery is possible even if BitGo as a company fails, which is a structural feature institutions value when underwriting custody risk. BitGo's regulation page documents licensing across more than 13 jurisdictions. The firm processed over $1.5T in transaction volume in 2024 per its 2025 disclosures, with tokenized RWA representing a growing share into 2026.
​

Fireblocks is an MPC-based digital asset infrastructure platform serving over 2,000 institutions, including banks, exchanges, and fund issuers. It is not itself a qualified custodian in the United States, but routes flows through partner qualified custodians (BNY Mellon, Fidelity Digital Assets, BitGo) and supports BUIDL, OUSG, BENJI, and USYC at the token-transfer layer.
​

Fireblocks uses multi-party computation (MPC) with threshold signing in place of single-key or multi-sig wallets, eliminating the single point of failure typical of cold-storage architectures. Per fireblocks.com, the platform's Fireblocks Network connects 1,800+ counterparties for atomic settlement. Fireblocks is the integration layer behind the wallets of many tokenized fund distributors, even when the legal custodian of record is a third party. The model is closer to a custody operating system than a chartered custodian.
​

Fireblocks does offer a chartered option through Fireblocks Trust Company, a Texas-chartered trust subsidiary, but the bulk of institutional usage runs through the MPC software platform integrated with partner custodians. The firm also operates a Tokenization Engine product that fund issuers including Securitize have referenced in their public materials. For tokenized RWAs, Fireblocks frequently sits in the stack as the operational wallet layer, with a separate qualified custodian holding the legal record of assets for regulated investment advisers.
​

Coinbase Custody Trust Company is a New York limited purpose trust company chartered by NYDFS, operating as a qualified custodian under SEC Rule 206(4)-2. It custodies BUIDL and OUSG for institutional clients of Coinbase Prime, segregates client assets onchain, and publishes a SOC 1 Type 2 and SOC 2 Type 2 report annually.
​

The NYDFS limited purpose trust charter was issued to Coinbase Custody Trust Company in 2018; the entity is bankruptcy-remote and segregates client assets per coinbase.com/institutional/custody. Coinbase Prime is the integration that pairs Coinbase Custody with execution and lending. BlackRock selected Coinbase as a service provider for parts of the BUIDL stack, and Coinbase Custody supports BUIDL transfers for qualifying clients.
​

Coinbase Custody publishes its SOC 1 Type 2 and SOC 2 Type 2 reports on request to qualifying institutional counterparties. The trust holds a $320M crime insurance policy syndicated through Aon, with additional FDIC pass-through coverage on cash positions held in linked partner banks. Cold storage uses geographically distributed hardware security modules with multi-party physical access controls. Coinbase publishes a public Proof of Reserves report covering certain assets, though tokenized fund holdings are reported separately to clients.
​

Komainu is a regulated digital asset custodian co-founded by Nomura, Ledger, and CoinShares, headquartered in Jersey with operations across the UK, Dubai, and Ireland. It holds a Jersey Financial Services Commission license and a Dubai VARA license, and serves institutional clients seeking non-US qualified custodian equivalents for tokenized funds and digital assets.
​

Per the firm's site, Komainu uses Ledger Vault hardware infrastructure and segregates assets across cold and warm tiers. The Jersey Financial Services Commission registration and Dubai's VARA license make Komainu a recognized counterparty for European and Middle Eastern institutional investors allocating to tokenized treasuries. Komainu announced integrations with multiple tokenized fund issuers through 2025, though the support set is narrower than BitGo or Anchorage as of Q1 2026.
​

The five providers differ on charter, scope, insurance, and tokenized fund support. The table below summarizes the dimensions that matter for an institutional allocator picking a custodian for a tokenized treasury or money market position.
​

For US registered investment advisers subject to Rule 206(4)-2, Anchorage, BitGo, and Coinbase Custody are the three native qualified custodians on this list. Fireblocks is the operational layer that often sits behind them. Komainu serves the European and Middle Eastern equivalents.
​

BUIDL and OUSG integration follows a similar pattern. The fund issuer mints tokens through Securitize, the transfer agent of record, and the custodian holds the token in a segregated onchain account on behalf of the institutional investor. Subscriptions, redemptions, and intra-fund transfers settle as token movements between whitelisted addresses controlled by approved custodians.
​

BlackRock's BUIDL launched in March 2024 on Ethereum, with Securitize as transfer agent and a panel of custodians including BNY Mellon (cash leg), Anchorage, BitGo, and Fireblocks for the token leg. Ondo's OUSG uses a similar pattern: Ondo issues tokens via Securitize, and qualifying institutional holders custody through BitGo, Anchorage, or Coinbase. Redemptions process T+0 for OUSG and T+1 for BUIDL per each issuer's documentation.
​

The whitelist mechanism is the structural feature that keeps tokenized funds compliant. Each fund's onchain contract maintains a list of approved addresses, and transfers between non-whitelisted addresses revert. Custodians submit their segregated client wallets for whitelisting after KYC and accredited investor verification through Securitize ID. This is the technical reason custody choice matters: an investor cannot move a BUIDL or OUSG position to a self-custodied wallet that has not been added to the issuer's allowlist. The custodian is therefore not interchangeable post-purchase without coordinating with the transfer agent.
​

Fireblocks itself is a software platform and not a US qualified custodian. The firm operates Fireblocks Trust Company, a Texas-chartered trust, but most institutional usage routes through partner qualified custodians such as BNY Mellon, BitGo, or Fidelity Digital Assets. Investment advisers subject to Rule 206(4)-2 should confirm which legal entity holds custody before relying on Fireblocks alone.
​

BlackRock's BUIDL is custodied at the token level by a panel that includes Anchorage Digital Bank, BitGo Trust, Coinbase Custody, and Fireblocks integrations. BNY Mellon handles the cash leg of the fund. Securitize is the transfer agent of record and maintains the onchain whitelist of approved holder addresses. Each custodian onboards BUIDL clients through its own institutional process.
​

Insurance varies by custodian. BitGo carries a $250M Lloyd's of London policy. Coinbase Custody holds a $320M crime policy through Aon. Anchorage and Komainu carry Lloyd's syndicate coverage with limits disclosed under NDA. Insurance covers theft, fraud, and key-loss events but typically excludes smart contract exploits, protocol failures, and price volatility.
​

Institutions evaluating a custodian for tokenized RWAs should weigh five factors: qualified-custodian status under Rule 206(4)-2, chain coverage for the specific tokenized fund, insurance limits relative to the position size, operational integrations with the fund's transfer agent, and the legal entity holding the charter. The right answer depends on jurisdiction and the specific fund mix.
​

A US registered investment adviser custodying BUIDL for a multi-billion-dollar treasury allocation typically picks Anchorage or BNY Mellon for federal-bank-level oversight. A crypto-native trading firm running OUSG positions alongside spot stablecoins often picks BitGo or Fireblocks for the operational integration with Securitize and Ondo. A European pension allocating into tokenized treasuries through a MiCA-regulated structure looks at Komainu or BitGo Europe. The picks are not interchangeable; each combines a charter, an asset list, and an integration set.
​

Eco focuses on routing and settlement for stablecoins and tokenized assets across chains, not on custody itself. When an institutional allocator wants to move BUIDL from Ethereum to a sidechain holding venue, or rebalance USDC into OUSG and back, the custodian holds the assets and Eco Routes provides the cross-chain transfer rail. The two layers compose: a qualified custodian for safekeeping, and a routing layer for movement.
