Bitkey is a next-generation, Bitcoin-only, non-custodial wallet built for everyday users and long-term holders. Its security architecture ensures you always remain in control, while still giving you the flexibility to recover access when a device is lost or replaced.
Only you control your keys—never the company.
Hardware key, mobile key, and cloud backup key.
Offline device ensures safe signing of sensitive actions.
Simplified recovery through multisig—not mnemonic words.
Built exclusively for BTC to reduce risk and complexity.
Developed by Block, a global leader in financial technology.
Bitkey's 2-of-3 multi-signature model ensures that no single device or platform can move your Bitcoin on its own. You will have access to three keys:
Stored securely on your smartphone
Stored offline on your Bitkey hardware device
Cloud-stored, encrypted backup used only in emergencies
To approve a transaction, any two keys must work together.
This protects you from hackers, SIM swaps, loss of device, and unauthorized access—even if one key is compromised.
