Half way through August and still waiting for last month's rewards....
IDEX presents itself as a Decentralized exchange (DEX), but from the looks of it, every transaction have to go through their wallet : 0x2a0c0DBEcC7E4D658f48E01e3fA353F44050c208 .
This means you never trade directly from your own wallet. Which is the point of a DEX.
What is planned in the future to increase the decentralization of IDEX?
