Why, What & FAQ
LI.FI is a cross-chain bridge aggregation protocol that supports any-2-any swaps by aggregating bridges and connecting them to DEXes and DEX aggregators.
In a nutshell, we're like 1inch & Paraswap for bridges, we choose the best bridge to move funds from one chain to another, but since bridges only support stable-coins and a few other coins, we have DEXes on both sides of the bridges to swap before and after the bridge, thus facilitating any-2-any swaps across chains.
For example, AAVE on Polygon -> DAI on Polygon using Paraswap -> DAI on Avalanche using NXTP -> SPELL on Avalanche using Paraswap

If you're a DEX, dApp or wallet, it is in your best interest to integrate our Install LI.FI SDK to keep users in your interface in order to allow on-chain as well as cross-chain swaps and a combination of both.
If you're a yield aggregation protocol or another dapp, integrate our smart contract for the fastest and most reliable transfer of funds across chains.

For whom is our SDK & API?

Literally for anyone who thinks about going cross-chain. But there are two use-cases from which it's the most obvious: DEXs (and DEX aggregators) as well as Wallets will find it to be a low hanging fruit, integrating our SDK and API to keep users at their interface.
