OP_VAULT (BIP-345)
Smart Contracts● Common
A proposed opcode enabling native vault functionality with secure recovery paths. Allows time-delayed withdrawals where funds can be clawed back to a recovery address if keys are compromised, without requiring pre-signed transactions.
Technical Notes
OP_VAULT specifies: trigger authorization, recovery authorization, spend delay, and target outputs. OP_VAULT_RECOVER enables immediate sweep to recovery during delay period. Uses transaction introspection without full covenant capability.
