Nunchuk 2.0 Adds Autonomous On-Chain Bitcoin Inheritance
Nunchuk 2.0 introduced an inheritance design using Bitcoin multisig, Miniscript and timelocks so heirs could recover funds through an autonomous failsafe path even if Nunchuk itself were unavailable.
On November 12, Nunchuk announced version 2.0 with an autonomous inheritance mechanism for Bitcoin self-custody. The design combined its assisted inheritance service with an on-chain recovery path constructed from multisignature policies, Miniscript and timelocks.
The central problem was long familiar to self-custody users: controlling one’s own keys removes dependence on a custodian, but it also creates the risk that bitcoin becomes inaccessible after death or incapacity. Nunchuk’s design attempted to bridge that gap by allowing a normal assisted process while preserving a recovery path that could eventually be executed by heirs without relying on the company to remain available.
The release was historically useful because it showed Bitcoin custody products moving beyond simple wallet security toward life-cycle planning. Rather than treating inheritance as a legal instruction layered on top of a custodian, the design used Bitcoin script conditions to make part of the succession plan enforceable on-chain.
