LI.FI is a bridge & DEX aggregation protocol that abstracts away the most crucial financial infrastructure to move in and out of any position on any chain — the one gateway to access all DeFi. It helps you to offer on-chain swaps, cross-chain swaps, and a combination of both. Arbitrary function calls and cross-data messaging allow for more complex strategies. They aggregated all the bridges, DEXs, and DEX aggregators so that you don't have to.
