# Aggregator

The router for OpenXSwap on Optimism aggregates liquidity from OpenXSwap, Velodrome, and Zip Swap, allowing users to utilize liquidity on each exchange with just one transaction. We intend to add more exchanges to the aggregator as other projects deploy on Optimism. 

Our aggregator is our "most deployed" contract. It is available on the following chains:
