Security you can see
The secure dual-chip architecture reflects our values as a Swiss open-source security company: a secure chip is used for physical device hardening in combination with fully open-source firmware. The firmware has deterministic builds, which means you can verify what you are installing: Don’t trust, verify!
Through our bug bounty program we encourage independent reviews of the firmware and responsible disclosure of any findings.
Supported Bitcoin wallets
BitBoxApp, Electrum, Specter, Sparrow
Supported nodes
Nodl, myNode, Umbrel, RaspiBlitz, ElectrumX or Electrs server.
Bitcoin-only, forever
The BitBox02 Bitcoin-only will only ever have Bitcoin firmware. Nothing else. Unlike other hardware wallets, the Bitcoin-only edition cannot be reset to support other coins. The Bitcoin-only firmware is locked down at factory setup.
