An early implementation of a decentralized exchange, 0x is a flexible tool for extending the Ethereum ecosystem. Zero-X (0x) provides open-source modules that can be easily integrated into almost any digital environment. With trading tools ranging from over-the-counter exchanges to DeFi lending protocols, ZRX provides digital services for developers who want to use the Ethereum blockchain.
