IDEX is a cryptocurrency token linked to the IDEX decentralized exchange. It’s an ERC-20 token on the Ethereum blockchain, used for governance and operations on the exchange. Token holders can vote on decisions, get a share of trading fees, and pay transaction fees. IDEX combines the speed of centralized exchanges with the security of decentralized ones, using a hybrid architecture that leverages off-chain and on-chain processes. It was created by Alex Wearn and Philip Wearn of Aurora Labs S.A.
