Just a month ago, BitPay said they had no plans to support Bitcoin Cash, and now they're trying to force a new address format on everybody. On August 14, , Bitpay said: BitPay does not support Bitcoin Cash payments, and we have no plans to upgrade our software to support the Bitcoin Cash fork. Like Bitcoin, Bitcoin Cash supports pay to public key hash (p2pkh) and pay to script hash (p2sh) addresses. These addresses include a version byte. To prevent users from unintentionally sending BCH to a BTC wallet or BTC to a BCH wallet, we will use a distinct version byte for BCH addresses. Jan 16, · The new release (+) of the BitPay and Copay wallets support this Cashaddr format for Bitcoin Cash addresses by default. This address format protects Bitcoin Cash wallet users from mistaken payments to BTC addresses, just like the format we were using before.

We will follow these conventions in all of our software that supports the Bitcoin Cash block chain. Like Bitcoin, Bitcoin Cash supports pay to public key hash p2pkh and pay to script hash p2sh addresses.
These addresses include a version byte. The version byte is set to 28 for p2pkh addresses and 40 for p2sh addresses. All BitPay software, including block explorers, will use these new address versions. Historical data extending back prior to the BCH fork will also be presented using these new conventions.
This means that in some circumstances when researching history of both BTC and BCH, it may be necessary to convert addresses between formats. To stop that from happening, we adopted new format conventions for addresses:.
Instead of the address starting with a 1 or a 3, we had Bitcoin Cash addresses start with a C. So far, this has prevented many Bitcoin Cash users from mistakenly sending to Bitcoin addresses. But since many other services and wallets do not use our address format, this can make it hard to use Bitcoin Cash outside of the BitPay and Copay wallets. It has been possible to translate between address formats , but this is not a simple fix for most users. Other groups in the Bitcoin Cash ecosystem have also been aware of the potential confusion caused by the legacy BCH address format.
Many services and wallet providers in the Bitcoin Cash ecosystem are moving to adopt this format. We are joining them. The new release 3. This address format protects Bitcoin Cash wallet users from mistaken payments to BTC addresses, just like the format we were using before. We also expect most Bitcoin Cash wallets and exchanges to adopt the Cashaddr format in the coming months.
This change will bring greater compatibility with the Bitcoin Cash ecosystem, along with more security against the risk of mistaken payments to Bitcoin addresses.
