DEX.io runs on the Ethereum network, so there is no need of user registration or certification for trading cryptocurrencies. Each transaction will be recorded on the chain. User signature/authorization is required for any asset changes (withdraw within smart contract, transfer and trade, etc.). It enables auditable, secure and transparent transactions.
Through the off-chain relay service provider (Relayer), DEX.io efficiently matches the orders of buyers and sellers. It solves the problems of slow matching and high cost for on-chain transactions.
