Do Counterparty addresses use checksum?

I’m frustrated with Ethereum mishaps when people lose funds. Why they cannot use checksum? I know Bitcoin does. How about Counterparty?

Yes, a Counterparty address has a checksum. In fact, every Bitcoin address is a Counterparty address, and vice versa. Counterparty is a layer on top of Bitcoin, so all the security features of Bitcoin also apply to Counterparty.
