Definition
The BitBox02 is a hardware wallet developed and manufactured by Shift Crypto, a company based in Switzerland. It stores private keys and signs transactions on a dedicated device that connects to a host computer or phone over USB-C, with on-device confirmation of addresses and amounts. It ships in two editions: a Bitcoin-only edition and a multi-asset edition that additionally supports other supported networks and tokens.
Open-source status
The BitBox02 firmware is open source and supports deterministic (reproducible) builds, so an independent reviewer can rebuild the firmware from source and confirm it matches the released image. Shift Crypto publishes the firmware and companion application code, and the design pairs a general-purpose microcontroller with a dedicated secure chip to protect key material against physical extraction.
Interface and backup
Rather than physical buttons, the BitBox02 uses capacitive touch sliders along the edges of the device for navigation and confirmation. It can back up the wallet seed to a bundled microSD card in addition to a written recovery phrase, and it pairs with the BitBoxApp desktop and mobile software for sending, receiving, and coin management.
