0x Protocol(ZRX)

Overview

0x Protocol is an open-source protocol designed to facilitate token exchange on Ethereum and EVM-compatible networks. Launched in 2017 by co-founders Will Warren and Amir Bandeali, it introduced a model in which orders are created and signed off-chain while only final settlement is executed on-chain.

ZRX is the ERC-20 token used within the 0x ecosystem, serving purposes such as protocol governance voting and staking. Over time, 0x expanded into aggregator-style API services that source and route liquidity across multiple decentralized exchanges, and its infrastructure has been used to power swap functionality in various wallets and DeFi applications.
