The Frontier

Bitcoin Keeper uses Miniscript for inheritance, allowing users to add a time-locked 'inheritance key' that activates after a set period, turning a 2-of-3 multisig into a 2-of-4 or enabling a single-key emergency spend.

Bitcoin Keeper is building a contacts feature to enable in-app messaging for collaboration and future social recovery. Ben Kaufman views its current Miniscript inheritance as a form of social recovery where trusted parties hold time-locked keys.
