Why trust this view
Bitkey evidence summary
Slow down if
You want fully independent, seed-only recovery or broad hardware-wallet interoperability.
This is the first tradeoff to read before treating the wallet as a fit.
Main risk
Recovery convenience depends on the Bitkey app, hardware, cloud backup, and service design staying available.
Operational and recovery risk matter more than feature checklists for self-custody.

Methodology
How this wallet is evaluated.
Recovery safety
Can a user recover under stress without handing unilateral control to a provider?
Key control
Who signs, how many keys exist, and whether multisig or hardware separation is available.
Ease of use
Whether the setup burden matches the likely user and balance size.
Hardware support
Whether long-term savings can use dedicated signing devices and coordinator flows.
Privacy tooling
Whether the wallet supports power-user controls such as PSBTs, descriptors, Tor, or coin control.

OfficialBitkey product / security pages (official)
2-of-3 multisig with hardware key (offline, biometric), app key (encrypted to user cloud), and server key (AWS Nitro Enclaves); server key 'can't move money by itself'; recovery via cloud backup and Recovery Contacts; no traditional seed phrase. Product page confirms Bitcoin-only and the integrated hardware device.
