Timelocks and Their Use in Recovery Solutions
summary
Explains practical recovery plans built from pre-signed transactions using nLockTime and nSequence, with examples in Trezor Suite and an Electrum time lock recovery plugin that creates a 600 sats alert tx plus a 90 days configurable recovery tx; shows limits: spending any input invalidates signed recoveries, you cannot add new UTXOs to an existing plan, relative lock max ≈388 days, and alternatives like Liana’s delayed-key 2-of-5 fallback or CPFP to accelerate broadcasting.
