I think there is some misunderstanding about the DEX that we plan to implement. The purpose of our DEX is to allow cross-chain swaps as well as a local platform to interact with centralized exchanges. This prevents access by a third party to your coins as in the case of storing them at a exchange.
Our DEX is NOT the same as XCP, NXT or colored coins implementations.
Oh that sounds a lot more interesting. Can all chains be swapped between each other or just certain ones? I'd love to stop using poloniex and bittrex but I have to because I want to do cross chain trades.
Cross chain trades will happen between those currencies which are tested and running with iguana.
Those are bitcoin protocol compatible currencies and we have more than dozens tested to work with iguana. As more currencies are tested and are supported those will be able to do cross chain atomic trades via EasyDEX.
Komodo, Zcash, Bitcoin, BitcoinDark, are few important example coins to mention. There are more. If you want to know if any of your favourite currency works or can be run on iguana, please help testing those currencies. Get in touch with devs on SuperNET slack.
