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.
Oasis App is an open-source DeFi product developed by the Maker Foundation. An original OasisDEX project was closed in January, 2019. With the help of Oasis App, you can trade and borrow Ethereum tokens.
