## Custodian

A custodian is a specialized financial institution or service provider that holds and protects assets on behalf of clients. In the digital asset space, custodians provide institutional-grade security, insurance, and regulatory compliance for large-scale holdings.

They typically employ a combination of cold storage, multi-sig, and MPC technologies to ensure that client assets are secure and recoverable. Custodians act as a trusted intermediary, offering services like asset segregation, audit trails, and reporting that are necessary for traditional finance players to enter the crypto market.

By offloading the burden of security and key management to a professional entity, clients can focus on investment strategy. Their role is pivotal in bridging the gap between legacy financial systems and the digital asset economy.
