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.
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.

Connect your BitBox02 to your favorite wallet to unlock even more features.
The Bitcoin open-source ecosystem allows permissionless innovation and we support that by using open standards and enabling easy integration into these projects. The BitBoxApp connects to any Electrum server and the BitBox02 can be used through Electrum, HWI, our JavaScript API as well as our Python and Go libraries.
BitBoxApp, Electrum, Specter, Sparrow
Nodl, myNode, Umbrel, RaspiBlitz, ElectrumX or Electrs server.
The companion to the BitBox02, the BitBoxApp empowers you with cutting edge features so you can stay in control of your coins.
We don't want your data. When connecting your own full node to our desktop app you stay in control of your personal information.
Select which coins you want to spend to provide you with tighter control over what information you reveal on the blockchain.
Improve your privacy by optionally directing all your transaction activities via Tor.
By default the BitBox02 uses the most modern Bech32 address format so you can save on transaction fees.
