0x
0x is the open exchange infrastructure powering token swaps for many of crypto's largest apps - Coinbase, Robinhood, Phantom, MetaMask, Matcha and more. Through its Swap API, gasless transactions, and the underlying 0x Protocol, the company aggregates liquidity from hundreds of sources across the major chains so developers can ship trading experiences without building order routing themselves.
Will Warren
Will Warren co-founded 0x in October 2016 alongside Amir Bandeali, building the open protocol that became foundational DeFi infrastructure for peer-to-peer trading of Ethereum-based digital assets. A former applied physics researcher at Los Alamos National Laboratory who left a PhD program in structural engineering to bet everything on Ethereum, Warren grew 0x from a whitepaper into a protocol powering billions in DEX volume and a developer platform serving the broadest ecosystem of DeFi apps, wallets, and market makers. In May 2026 he stepped down as Co-CEO while remaining a major shareholder and board member.
