BitBox02 features
Level up your security with the following features.
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.
You own your data. BitBox02 keeps your keys safe.
The BitBox02 features a dual chip design with a secure chip. The source code has been independently audited by security researchers and is fully open source.
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.
Bech32
By default the BitBox02 Bitcoin-only Edition uses the most modern Bech32 address format so you can save on transaction fees.
