IEX function has been built into the imToken 2.0 international version (utilizing Atomic Token Swap smart contract), developed jointly with Kyber Network. Through this function, users will be able to refer to real-time exchange rates and exchange digital assets seamlessly.
Kyber Network is a decentralized exchange service provider that allows users to convert digital assets instantaneously and securely.
PS: Since the IEX is based on the Kyber smart contract, so each time you need pay the miner fees when using IEX.
