NEX is a platform for high performance decentralized exchange and payment. NEX leverages an off-chain matching engine to enable faster and more complex trades across multiple blockchains such as NEO and Ethereum. NEX handles enormous trade volume through its unique publicly verifiable off-chain matching engine. NEX payment service enables third-party smart contracts on NEO to send and receive global assets such as NEO and GAS as part of their computation. NEX handles complex order types that aren’t currently available on other decentralized exchanges such as market and limit orders. The NEX wallet extension underpins the NEX ecosystem, allowing quick and seamless coordination between NEX, dApps and websites. NEX allows for performant trades between tokens based on the NEO and Ethereum networks.
