A Bitcoin wallet, nothing else
The BitBox02 Bitcoin-only edition has limited firmware and only supports Bitcoin. Less code means less attack surface, which further improves your security when only storing Bitcoin.
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
Nodl, myNode, Umbrel, RaspiBlitz, ElectrumX or Electrs server.
