Firmware

Upload firmware to your BitBox using the Options menu item Upgrade Firmware, available in the desktop app. If you have problems after upgrading the firmware, check that you are also using the latest desktop app.

Downloads contain a deterministic build of the firmware and a set of ECDSA signatures of the build. The signatures are checked inside the BitBox bootloader at every plug in. Invalid or modified firmware cannot run.

Source code is available on GitHub. If you wish, you can verify that the BitBox is running the same code by building the firmware on your own and uploading it.
