ZRX (0x Protocol)
Summary
0x Protocol (ticker: ZRX) is a decentralized exchange infrastructure protocol founded in 2016 by Will Warren and Amir Bandeali, enabling peer-to-peer token trading on Ethereum and multiple other chains. The project conducted a $24 million ICO in August 2017, has processed over $200 billion in cumulative trading volume, and operates the Matcha DEX aggregator. In September 2023, the U.S. CFTC settled charges against ZeroEx, Inc.—the corporate entity behind 0x—for $200,000 related to the unlicensed offering of leveraged token trading; and in January 2026 a third-party integration (SwapNet) used in Matcha Meta suffered a $13.4 million exploit, though 0x's core protocol contracts were not compromised.
