The U.S. Securities and Exchange Commission (SEC) has provided long-awaited clarity on how state-chartered trust companies fit into federal custody requirements for digital assets. In a no-action letter issued on September 30, the SEC confirmed that investment advisers can use state-chartered trust companies as qualified custodians for cryptocurrencies. This decision directly impacts firms such as Ripple and Coinbase, both of which operate trust structures that were previously questioned under federal law. The new staff guidance redefines how the term “bank” applies under the Investment Advisers Act of 1940 and the Investment Company Act of 1940, resolving years of uncertainty about whether crypto-focused trust companies meet the definition.
For investment advisers, safeguarding client assets with a recognized custodian is a legal requirement. Until now, questions lingered over whether state-chartered crypto trust companies could fulfill that role under federal custody standards. Brian Daly, Director of the SEC’s Division of Investment Management, explained that the move was necessary to close gaps in interpretation, noting that additional clarity was needed because state-chartered trust companies were not universally seen as eligible custodians for crypto assets. By removing ambiguity, the SEC has created a pathway for digital asset firms to become trusted custodians for registered investment funds, bridging a key gap between blockchain innovation and traditional finance.
Ripple and Coinbase, both of which maintain state-chartered trust entities, now stand to benefit directly from the updated guidance. The letter positions them as eligible crypto custodians for institutions seeking regulatory certainty, an important milestone for companies at the intersection of digital assets and regulated markets. Bloomberg ETF analyst James Seyffart described the decision as a textbook example of more clarity for the digital asset space and exactly the sort of step that the industry has been asking for over the last several years. This recognition strengthens the position of leading crypto firms that have long pushed for integration into mainstream financial frameworks.
The SEC’s letter also sets out clear conditions for advisers relying on state trust companies for custody. Advisers are required to conduct annual reviews to confirm that custodians have sufficient safeguards against theft, loss, and misappropriation of assets. Custodians must provide audited financial statements prepared under GAAP as well as internal control reports verified by independent accountants. In addition, custodial agreements must prohibit lending, pledging, or rehypothecating client crypto assets without explicit client consent. To ensure investor protection, crypto assets held in custody must also be segregated from the custodian’s own balance sheet. These requirements bring custodianship of digital assets into alignment with practices long used in traditional financial services.
The guidance applies specifically to state trust companies authorized by state banking regulators to provide crypto custody services. These institutions must comply with comprehensive frameworks that include licensing obligations, minimum capital standards, regular examinations, and the possibility of enforcement actions in cases of non-compliance. By tying eligibility to regulatory oversight, the SEC is attempting to balance investor protection with support for innovation in financial technology.
For the broader industry, the SEC’s decision is being seen as a turning point for digital asset firms seeking to offer institutional-grade custody. The recognition of Ripple and Coinbase as potential custodians signals a major step in legitimizing crypto custody within the regulated financial system. Analysts also believe that the letter could accelerate the development of digital asset funds, exchange-traded products, and tokenized securities by providing clearer custody pathways. This development is especially important for institutional investors who require robust legal and regulatory structures before allocating capital to emerging asset classes.
Although the no-action letter provides immediate clarity, the SEC has not ruled out the possibility of more formal rulemaking in the future. Daly emphasized that the guidance is designed to address today’s products, today’s managers, and today’s issues, leaving open the potential for updates as the digital asset market evolves. For now, however, Ripple, Coinbase, and other firms operating under similar structures have gained a significant opportunity to expand their roles in the financial system as recognized crypto custodians. This move not only benefits individual companies but also strengthens the foundations for broader institutional adoption of digital assets.
