Bitcoin firmware
Bitcoin firmware, or Bitcoin-only firmware, is a special version of the Trezor firmware which only facilitates Bitcoin operations. Running the Bitcoin-only firmware is optional and requires the user to install it manually.
Once it is loaded on the device, Trezor Suite will restrict the selection of available cryptocurrencies. The Bitcoin-only firmware was introduced on 4 September, 2019.
- When loading the Bitcoin firmware on your Trezor Model T, you must have firmware version 2.1.0 or newer installed on your device first.
- Trezor devices running the Bitcoin-only firmware cannot be used as two-factor authentication tokens (U2F/WebAuth).
