user38618: My CoPay wallet shows my Bitcoin Cash address as CTGUTUgVAwHugpf4CyyjAvj8DCFkE4tpEq. What's going on? I thought both Bitcoin and Bitcoin Cash addresses start with 1 or 3?

user38618: It's a new address format for Bitcoin Cash proposed by BitPay, to prevent BTC/BCC address confusion. It's not widely used, currently.

The old addresses that start with 1 (P2PKH) are converted to addresses that start with C
The old addresses that start with 3 (P2SH) are converted to addresses that start with H

user82730: The previous answer, while correct, is outdated. While BitPay did use a proprietary format early on, we quickly adopted the CashAddr format for Bitcoin Cash/BCH transactions.
