LI.FI - a bridge protocol with favorable working conditions

Description of LI.FI

Li.Fi supports all bridging, gives you access to multiple, and programmatically handles fallback and decision making. LI.FI not only connects bridges, but also connects to various kinds of DEX aggregators. If they are not available, then go directly to the DEX to find the best exchange to obtain the desired token and allow the whole process to begin with any asset. As a DEX bridge and aggregator, LI.FI can route any asset in any chain to the desired asset in the desired chain, thus providing a wonderful UX for its users.

There are several ways to get started with a project:

TypeScript/Javascript SDK	The JS/TS SDK can be injected into any frontend or backend so you can build your own UX/UI, based on bridging and sharing functionality.
API	The REST API provides you with all kinds of information and provides deeper and more custom integrations.
iFrame widget	Implemented in 5 minutes, the widget helps to connect users from anywhere in the world.
Embedded website	For browser-based applications, LI.FI dapps can also be embedded by using a custom URL.
Parameterized links	If you don't have time to integrate, go to a website with a preconfigured token and chain.

Vaults track returns across multiple chains and place their funds in the best possible way, find the most reliable, cheapest bridge with enough liquidity to deposit into protocols that generate the highest returns. With LI.FI, DApps can exchange data across chains and allow users to pledge, borrow and repay their loan across chains.

More about smart contracts

The LI.FI contract is built by using the EIP-2535 standard (polyhedral proxy).

All business logic is built by using contracts, which are located in src/Facets.LI.FI

A basic example is when a user moves from one chain to another, using the Hop protocol. The user interacts with the LI.FIDiamond contract, which will pass the specific Hop call to the HopFacet, which then passes the required calls + parameters to the Hop protocol contracts. The LiFiDiamond contract is deployed along with some supporting contracts that make it easy to do things like updating contracts, finding methods, verifying ownership and withdrawing funds.
