Episode notes
Bitkey ditched seed phrases for a recovery-focused 2-of-3 design: an app key, hardware key, and Block server key that use phones, hardware, and cloud access to help people retain control of their funds.
Clay Garrett, Bitkey lead at Block, joins Stephan Livera to explain the design trade-offs: safety as security plus recoverability, cloud backup that needs your hardware to decrypt, and why Bitkey does not treat vendor lock-in as its ethos.
They dig into recovery paths, multi-vendor trade-offs, transfer-without-hardware limits, Recovery Contacts and inheritance, a working FROST prototype, what covenants could move on-chain, chain code delegation, and privacy-conscious Electrum options.
