Process

Deceased Verification

Byzantine inheritance uses server-assisted timelocks. After a configurable inactivity period, the inheritance path activates automatically. Beneficiary can broadcast a pre-signed time-locked transaction.

Distribution Methods

Pre-configured inheritance transaction broadcasts automatically after timelock expiry. Beneficiary receives funds at a designated wallet address. Fully non-custodial inheritance — no intermediary needed.

Legal & Compliance

Non-custodial wallet — Nunchuk never holds user keys. Inheritance operates through Bitcoin's native scripting (timelocks), not legal contracts. Users can supplement with traditional estate documents.
