Bitcoin Cash (BCH) is a hard fork of Bitcoin (BTC) and shares the same transaction history up to the point of the fork. The Bitcoin Cash hard fork took place on 1 August 2017. The main differences between Bitcoin and Bitcoin Cash is the increased block size supported by Bitcoin Cash and the adoption of Segregated Witness by Bitcoin.

CashAddr address format

On 14 January 2018, Bitcoin Cash updated their standard address format, while maintaining compatibility with the old address formats. The new address format is called CashAddr. It has the following form:

bitcoincash:qpm2qsznhks23z7629mms6s4cwef74vcwvy22gdx6a 

Starting from firmware 1.6.2 and 2.0.7, Trezor devices will only use the new address format. For conversion between CashAddr and legacy address format, please use the following 3rd-party tool .


NoteDue to length constraints, Trezor Wallet and Trezor device display Bitcoin Cash addresses without the bitcoincash: prefix. If needed, please prepend the prefix manually.
