Date: May 2026 Software Category: Decentralized Exchange (DEX) Infrastructure / Smart Contract Framework Maintainer: 0x Project (0x Labs) License: Apache 2.0 Introduction In the rapidly evolving world of decentralized finance (DeFi), the 0x Protocol stands as a cornerstone for liquidity aggregation and peer-to-peer exchange. For developers integrating this protocol, version control is critical. While the 0x core smart contracts and TypeScript libraries are constantly updated, a specific request that often appears in developer forums is for 0x Version 8.9.1 Download .
