Bitcoin Multisig Custody Vaults

Unchained provides institutional-grade Bitcoin custody through collaborative multisig vault technology, serving individual investors, businesses, retirement accounts, and institutional clients. Using 2-of-3 multisig architecture, clients maintain control of two keys while Unchained secures a backup key, creating a custody model that eliminates single points of failure and prevents rehypothecation.

Custody Architecture

• Collaborative Custody Model: Clients control two of three keys required to move Bitcoin, with Unchained holding one backup key for recovery purposes
• Cold Storage Security: Bitcoin stored offline in cold storage, protecting against hacks and exchange failures
• Key Recovery Services: Professional assistance to recover Bitcoin access if one key is lost or stolen
• No Rehypothecation: Bitcoin cannot be lent, used, or moved by Unchained without client participation
• On-Chain Transparency: Clients can verify their Bitcoin holdings on the blockchain at any time
• Fault Tolerance: Multisig redundancy protects against small mistakes and security failures
