Hi, the founder of Bitsquare here. I would like to add ZCoin to Bitsquare and wanted to know if there are any extra requirements needed? In Bitsquare the altcoin exchange is outside of our system so to add the coin is usually trivial (user A sends coin to user B on his ZCoin wallet, only receivers address is needed to be known to user A). Though in cases of a dispute the arbitrator need to have a way to verify the transactions, which is usually simple with the block explorer to look up the input for the receiver address. But for instance with CryptoNote coins that is not possible as the block explorers data does not reveal that info. So that is why I ask if there is anything special at ZCoin in that regards. If the receiver address reveals the transaction on the explorer all is fine, if not we would need some extra solution (Monero has private tx keys which can be handed over to the arbitrator form the sender to proof the tx).

Beside that which exchanges will support ZCoin initially, could not find info in the webpage.
