0x
The professional grade liquidity aggregator.
Overview
0x is a core piece of DeFi infrastructure that enables developers to build applications that tap into aggregated liquidity from across the Web3 ecosystem. Its primary product, the 0x API, intelligently sources liquidity from dozens of on-chain exchanges to provide developers with the best possible price for token swaps. This allows developers to easily add trading functionality to their wallets, dApps, or websites.

- Support for multiple EVM chains
- Gasless swaps via meta-transactions
- Open-source smart contracts
🎯 Key Differentiators

💡 Check With Vendor
Verify these considerations match your specific requirements:
- Applications that don't involve token trading.
- Projects that need to interact with a single, specific liquidity source.
🏆 Alternatives
Building and maintaining integrations with dozens of DEXs is incredibly complex. 0x abstracts all of that away behind a single API, saving developers significant time and ensuring their users always get a competitive price.
