0x Protocol protocol
Overview
0x positions itself as a trading API covering multiple blockchains, pulling liquidity from over 150 sources on EVM chains, Solana, Tron and HyperCore. Its main offerings are Swap APIs: one for Ethereum and EVM-compatible networks, one for native SPL token trading on Solana, and a Cross-Chain API for moving assets between distinct chains. Supporting these are a Gasless API, enabling transactions without requiring the chain's native token for fees, and a Trade Analytics API to examine swaps executed via the protocol. 0x functions as infrastructure rather than a direct consumer tool; wallets, exchanges and DeFi interfaces embed its routing to achieve execution across fragmented markets. Recent work includes exact-output swaps, simultaneous gasless trades, AI agent integrations, enhanced signature support for smart accounts, and a dedicated MCP server for AI client applications.
