What Our Community is Saying...

The UI is wonderful. It's the convenience of EtherDelta but with the UI of GDAX.

The ability to buy and sell tokens directly from my ledger is the ultimate form of security. Decentralized exchanges are providing the safety and security that crypto desperately needs!

They provide one of the only DEX API's that supports free order cancellation, which is key for our market making strategy. Their SDK is extremely well documented. Support is professional and fast. Brilliant!
