TREZOR device supports both BTC and B2X.

The TREZOR device supports both BTC and B2X. For both coins, new and legacy addresses will be supported.

However, as SegWit2X will not implement replay protection, there are certain steps you need to take before you can use both coins safely. We will prepare a guide for you to follow, should you wish to split your coins and use both coins.

Disambiguation: The fork ahead.

If you only care about BTC and don’t need B2X, no action is required. Use your bitcoin as you would normally.

If you only care about B2X and don’t need BTC, no action is required. Use your B2X as you would use other coins. See the end of the splitting guide.

If you want both BTC and B2X, please follow the guide below to split the coins correctly. Note that this process is manual and is without any warranties, due to the lack of replay protection.

Important note: This is not the same process as during Bitcoin Cash fork

Bitcoin Cash implemented replay protection during their hard fork, meaning the coin splitting process was easier to implement. Please take all precautions, and pay close attention to the guide.
