Mdex is based on the dual-chain DEX model of Huobi Eco-Chain (Heco) and Ethereum, and supports a "dual mining mechanism" of liquidity and transaction mining. Mdex is a decentralized trading product with automatic market making based on the concept of capital pool. As a fully functional DEX, we proposed and realized the dual-chain DEX model based on Huobi ecological chain and Ethereum public chain. It integrates the advantages of low transaction cost of Huobi ecological chain and the prosperity of Ethereum ecosystem, and supports the "dual mining mechanism" of liquidity mining and transaction mining. Mdex is committed to creating a DeFi platform integrating DEX, IMO and DAO on huobi ecological chain Heco, to provide users with decentralized token exchange services with more security and reliability, diversified asset selection and configuration, and higher expected return on investment.
