New 0x API Liquidity Sources - June 2022


In June 2022, the following liquidity sources were added to 0x API to ensure we’re providing developers access to the deepest liquidity and best executed swap prices across Ethereum, BNB Chain, Polygon, Avalanche, Fantom, Celo, and Optimism.

We commonly receive requests from developers to add new liquidity sources and provide updates when new ones are added. Moving forward, we’ll be sharing these updates at a regular cadence.
