Idex claims to be the first hybrid liquidity DEX that combines an order book model with an automated market maker. It blends the performance and features of a traditional order book model with the security and liquidity of an AMM. Idex takes an innovative approach to decentralized exchanges by combining an off-chain trading engine with on-chain trade settlement. Users benefit from that in several ways.First, this approach does away with failed trades and wasted money on gas fees, making the trading experience more pleasant and efficient. The instant trade execution means front-running or sandwich attacks are not possible and users can trade without waiting for previous trades to settle. As a result, more advanced order types and trading strategies can be executed since limit orders are possible, opening up arbitrage opportunities with other exchanges. Idex follows an ambitious roadmap that envisions a multi-chain future for the exchange, which currently runs on Ethereum and Binance Smart Chain. For the remainder of 2021, it plans to launch on second layer solutions and Polkadot and implement a referral. For the future, Idex plans to implement leverage trading and launch on additional layer one and layer two blockchains....
