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.
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.
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.
