There’s good news for Bitcoin Cash users as Trezor announces upcoming support for cashaddr, a BCH address format. The announcement is a significant development for Bitcoin Cash as support from the most popular hardware wallet could spell new money coming into the market, or at least increased security for those wishing to safeguard their investment carefully.
Cashaddr was developed as a way of distinguishing between Bitcoin Cash and Bitcoin Core addresses, and while it was supposedly expensive to implement the change, the move has paved the way for further innovations.
Pavol Rusnack of Satoshi Labs is often credited with the change, saying “I suggest to change the address version to something different, so it is obvious the address is a Bitcoin Cash address. (It can start with C for example). Don’t forget to change also address version for P2SH!”
