Why it matters
Digital assets introduce custody challenges that traditional finance never faced: irreversible transactions, bearer-instrument properties, and no central authority to reverse errors. Institutions providing digital asset custody must solve these problems with technology and process rather than relying on banking infrastructure.
How it works
A custody provider maintains secure infrastructure for key generation, storage, and transaction signing. Access controls define who can authorize transactions and under what conditions. Operations follow documented procedures with audit trails. Regular security assessments and reserve attestations verify the integrity of holdings.
Example
An institution evaluating bitcoin custody providers assesses their key storage architecture (cold vs hot ratio), signing procedures (single vs multisig), insurance coverage, proof of reserves practices, and withdrawal policies. These operational details determine the quality of custody.
