Qualified Custodian

A qualified custodian is a regulated financial institution — such as a bank, trust company, or registered broker-dealer — that holds client assets under specific legal and regulatory requirements. In the context of Bitcoin lending, it refers to third-party institutions that hold borrower collateral separately from the lender's own assets.

Regulatory context

Under the SEC's Custody Rule and related regulations, registered investment advisors are required to hold client assets with a qualified custodian. For Bitcoin lenders, using a qualified custodian for collateral is a trust signal indicating that your BTC is held in a regulated, segregated environment.

Why qualified custody matters for borrowers

If your lender holds Bitcoin directly (in their own wallets), your collateral is commingled with their assets and exposed to their business risk. If the lender fails, your Bitcoin may be treated as a general creditor claim in bankruptcy. A qualified custodian holds your collateral separately, which provides stronger legal protection.

Examples of qualified custodians in Bitcoin lending

Coinbase Prime and BitGo are among the most commonly used qualified custodians by Bitcoin lenders. Arch Lending uses Coinbase Prime as its custodian. This does not mean your Bitcoin is completely risk-free, but it reduces custodial counterparty risk compared to lender-held arrangements.
