IDEX is a cryptocurrency exchange that was launched early last year. The exchange aims to offer users the experience of a centralized exchange that boasts the security benefits of a decentralized platform.
The exchange provides a peer-to-peer trading environment. It also uses smart contracts to relay transactions over the Ethereum blockchain, and this allows the order book of your account to be updated in real-time.
Koinex was an Indian exchange established in 2017. In June 2019, the exchange announced that its operation would be ceased. The deadline for withdrawal was scheduled for July 15, 2019.
