what's 0x protocol?
0x Protocol is a decentralized exchange infrastructure that enables the creation of peer-to-peer exchanges for ERC20 tokens on Ethereum and other blockchains. It provides a suite of APIs, including the 0x API, for developers to build financial applications with access to aggregated liquidity from multiple DEXs like Uniswap, Balancer, and Curve. The protocol facilitates efficient token swaps at optimal prices by aggregating liquidity sources and optimizing trade execution. Key features include support for multichain deployments, RFQ (Request for Quote) systems for large trades, and tools for gas optimization and MEV protection. 0x powers numerous DeFi applications and wallets, handling billions in trading volume.
