LI.FI is the routing and execution layer that connects any application to all on-chain liquidity across chains, bridges, DEXs, solvers, and yield protocols through a single integration.

ā€‹
Why LI.FI

Blockchain infrastructure is fragmented across:
  • Dozens of chains and rollups
  • Multiple bridge protocols
  • DEX aggregators per ecosystem
  • Different token standards (USDC, USDC.e, wrapped assets, native gas tokens)
  • Emerging intent and solver networks
  • RWAs and hundreds of stablecoins
  • Yield opportunities and money markets
  • Perps DEXs & Orderbooks
Integrating these systems individually is expensive, brittle, and difficult to maintain. Data management and customer support tooling is painful on top. LI.FI abstracts this complexity behind a single integration.

ā€‹
What LI.FI Provides

LI.FI is the routing and orchestration layer that enables:
  • Same-chain swaps
  • Cross-chain swaps & bridging
  • Cross-chain contract calls
  • Multi-step transaction flows (bridge ā†’ swap ā†’ zap ā†’ deposit)
  • Finding and buying perps
  • Finding and zapping into yield opportunities
All through one unified API and SDK.

How It Works

LI.FI sits between your application and the fragmented liquidity landscape.
1

Aggregates

Bridges, DEXs, Solvers, Perp Orderbooks, and Yield protocols into a single interface.
2

Normalizes

Token standards and chain differences so your app never has to handle them directly.
3

Calculates

Optimal routes based on price, speed, gas cost, and execution reliability.
4

Executes

Transactions with built-in monitoring and fallback logic to maximise success.
You integrate once. LI.FI handles the routing logic and infrastructure maintenance.

ā€‹
Core Capabilities

Unified Routing

Access liquidity across major chains and ecosystems without maintaining individual integrations.

Smart Order Routing

Routes are optimised for best price, gas efficiency, execution success rate, and speed.

Execution Monitoring & Fallbacks

If a provider fails or a route becomes invalid, LI.FI automatically re-routes to maximise transaction success.

Token Standard Abstraction

Canonical token mapping prevents failures from wrapped assets and bridged variants (e.g. USDC vs USDC.e).

Cross-Chain Composability

Build programmable multi-step flows: swap + bridge, bridge + deposit, cross-chain zaps, and full DeFi workflows.

ā€‹
When to Use LI.FI

LI.FI is built for any application that requires reliable on-chain execution:
  • Wallets & Wallet-as-a-Service
  • Exchanges & trading desks
  • Fintechs, neobanks & Banking-as-a-Service
  • DeFi applications
  • On-ramp / off-ramp providers
  • AI agents executing on-chain
If your users need to move assets across chains or interact with fragmented liquidity, LI.FI removes the infrastructure burden.

Next Steps

SDK Integration

Integrate LI.FI into your application using the JavaScript/TypeScript SDK for full control over routes, execution, and token management.

API Reference

Explore the LI.FI REST API to fetch quotes, execute cross-chain transfers, and track transaction status directly via HTTP.
