IDEX is the fastest and most user-friendly decentralized Ethereum token exchange

IDEX’s unique design pairs an off-chain trading engine with an Ethereum smart contract. The off-chain infrastructure manages the trading experience, while the smart contract handles all funds, trade authorization, and final settlement. Traders on IDEX can trade continuously without waiting for transactions to mine, while behind the scenes the transaction arbiter properly sequences and dispatches authorized transactions to the blockchain, ensuring that the smart contract stays in sync with the off-chain balances.

By separating trade matching from execution, IDEX provides the speed and user experience of centralized exchanges combined with the security and auditability of the Ethereum Blockchain.

Watch the video below to see what it's like to trade on IDEX.
