DeFi Asset Custody Controls for Registered Investment Advisers
Summary
This article explains the tension between the U.S. Custody Rule and registered investment advisers’ use of DeFi assets and protocols. The rule generally expects client funds and securities to be held by a qualified custodian and independently verified, while some onchain assets and smart contract activities lack custodians able or willing to support them. Because an adviser’s authority to transact can count as custody, using such assets may create compliance uncertainty even when the adviser applies strong technical safeguards. The article frames this as a conflict between investor-protection requirements and the operational structure of decentralized systems.
As interim practices, it describes MPC key management with quorum approvals and separation of transaction approval, administration, and investment decisions. It also recommends independent audits, ongoing review of public-chain balances and transfers, and diligence on custody providers and protocols, including cybersecurity, solvency, smart-contract audits, governance, withdrawal ability, and contractual protections. These controls may support investor protection, but the article acknowledges that MPC does not itself meet the rule’s qualified-custodian requirement as currently applied. Regulatory flexibility or formal changes remain uncertain.
Key ideas
- The Custody Rule can apply when an adviser has authority to move or access client assets.
- Many DeFi-native assets lack qualified custodians, creating a gap between compliance obligations and available infrastructure.
- MPC wallets can distribute signing power and require quorum approval, but do not automatically satisfy the qualified-custodian requirement.
- Independent audits and public-chain monitoring can add oversight where qualified custody is unavailable.
- Advisers should assess provider and protocol security, solvency, governance, withdrawal paths, and legal protections.
