What Bitkey is
Bitkey is a Bitcoin-only hardware wallet system built around a 2-of-3 multisig model. Instead of relying on a single seed phrase, control is split across three keys: the customer holds two keys, and a third key is held for recovery purposes. Any two of the three keys are required to approve a transaction, and a physical device screen lets the customer verify what they are approving before it is signed.
The company providing the service holds one of the three keys but cannot move funds with it alone, since two keys are always required to authorize a transaction. Its role is described as assisting with security and recovery rather than holding custody of funds. The product supports Bitcoin only, and setup and use are described as guided, requiring the customer to connect the device and confirm transactions.
