LI.FI Cross-Chain Integration Guide

Use LI.FI when a Solana app, wallet, backend, or AI agent needs cross-chain token transfers, bridge aggregation, same-chain swaps, payment flows, or transfer status tracking. LI.FI exposes the same routing engine through REST API, SDK, MCP server, CLI, and Widget surfaces.

Overview

LI.FI is a multi-chain liquidity aggregation platform for swaps and bridging. For agent and backend integrations, the REST API is the lowest-dependency default. For frontend apps, prefer the SDK because it handles wallets, signing, execution tracking, and ecosystem-specific transaction handling. For MCP-compatible AI hosts, prefer the LI.FI MCP server for typed tool discovery.

Core capabilities:

• Quotes: Get a ready-to-sign transaction for the best route.
• Routes: Compare multiple route options and execute step-by-step.
• Status tracking: Track source and destination chain transfer progress.
• Discovery: Query supported chains, tokens, bridges, and exchanges at runtime.
• Solana support: Request Solana-specific chain/token data via chainTypes=SVM and use SOL as the Solana chain key in API examples.
