Bitkey Wallet, developed by Block (formerly Square), is a modern and secure Bitcoin-only self-custody wallet designed for users who want complete control of their digital assets. With its combination of a hardware device, mobile app, and multi-signature security model, Bitkey delivers both simplicity and strong protection for all types of Bitcoin users.
Bitkey is a non-custodial Bitcoin wallet that puts ownership fully in your hands. It uses a special 2-of-3 multi-signature system, involving your hardware device, your mobile app, and a cloud backup key. This ensures your Bitcoin remains safe even if one device is lost or compromised.
