IDEX consists of a smart contract, a transaction engine and a transaction processing system. You will pay 0.10% commission for market maker transactions and 0.20% commission for market-taking transactions on IDEX. Authorized transactions are forwarded to the system that manages the queue of pending transactions, they are sent sequentially to ensure that each transaction is issued in the correct order and that the smart contract balances remain in line with the exchange balances. Depending on the monthly transaction volume, IDEX coins are automatically distributed to users' wallets. It is seen that especially decentralized exchange users prefer IDEX and are satisfied with the platform.
