Bitcoin-only firmware on Trezor

Trezor Suite makes it easy for users to install both Bitcoin-only firmware (a lightweight version supporting only BTC accounts) or the full-featured Universal firmware (supporting all coins and tokens).

When initializing new Trezor devices, users can choose between Universal and Bitcoin-only firmware during the onboarding process in the ‘Firmware installation’ step.

If the device is already set-up with Universal firmware, you can switch to Bitcoin-only firmware in the Device settings menu:
 

• Click on the 'Settings' in the top-left corner of Trezor Suite to access the Settings menu
• In the ‘Device’ menu, scroll down to the ‘Firmware’ section
• Here you will see details of both the version and type of firmware installed:

   

• Click the ‘Switch to Bitcoin-only’ button and follow the instructions displayed in Trezor Suite and on your Trezor device screen.

With Bitcoin-only firmware installed, your Bitcoin accounts and balances will be shown, but all other coins will be deactivated. You will not lose any other currencies by installing Bitcoin-only firmware - they will simply not be discovered by Trezor Suite, and therefore will not be displayed.

If you wish to trade other cryptocurrencies, you will need to install the Universal firmware:
 

• Click on the "Settings in the top-left corner of Trezor Suite to access the Settings menu
• In the ‘Device’ menu, scroll down to the ‘Firmware’ section
• Here you will see details of both the version and type of firmware installed:

   

• Click the ‘Switch to Universal’ button and follow the instructions displayed in Trezor Suite and on your Trezor device screen.

Added advantages of running Bitcoin-only firmware include fewer regular updates (compared to the Universal firmware) and reduced risk of bugs or security issues.
