Looking into it a bit more. It seems as though you can deposit / withdraw a couple of currencies, such as Waves/Bitcoin/Litecoin/Ethereum. The deposits are turned into representative tokens, and the actual deposits may be managed by waves. Other tokens appear to be user generated tokens, even if they are representative of other actual tokens. If you are more familiar with their platform, what I need to figure out is how exactly DNotes could be included in their exchange.
