I am just trying to understand this.
Thank you.
Etherdelta only has trading enabled for ERC20 assets exchanging with Ethereum directly, though through the 0x OTC relay portal it's possible to create a trade request for any two tokens, given you have their smart contract address to add to your account cache if they're not listed as an official coin. After filling your request, you can share the relay publicly or directly with the trading party for them to look at or fill your trading order.
There's also several other networks starting exchanges over the Ethereum main network and gaining public use, so as more projects come into the fray with different approaches the service capability is sure to evolve.
Yes, first thing that crossed my mind was is it possible to build decentralized exchange with contracts like this.
So many good and unique news comparing with all other coins. This is just a proof that you should hodl IFLT.
