O3 Swap

O3 Swap is a cross-chain DEX built on the top EVM-compatible blockchains! Its token liquidity is both aggregated from the top DEXs on each chain and from on-chain liquidity pools deployed by O3 Labs. 

O3 Swap achieves both on-chain and cross-chain swaps quickly. Users can exchange tokens from any supported chain to another token freely. The one-click exchange of assets between multiple chains eliminates the need to reserve a gas fee for each chain.
