Bitkey
Bitcoin-only hardware wallet with built-in 2-of-3 multisig, no seed phrase required, and integrated inheritance. By Block. CA$360.
Bitkey is a Bitcoin-only hardware wallet built by Block (formerly Square) that eliminates single points of failure through a 2-of-3 multisig architecture. Instead of a seed phrase, control is distributed across three keys: your hardware device, your mobile app, and a recovery key held by Block. Any two of the three are required to move funds, meaning no single device, key, or company can act alone. Block cannot access or move your Bitcoin without your approval — their key exists only for assisted recovery. Bitkey features on-device transaction verification, integrated inheritance functionality, and is designed for users who want strong self-custody without the complexity of managing a seed phrase. Bitcoin-only firmware reduces attack surface. Priced at CA$360.
