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
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 → swap → zap → deposit)
- Finding and buying perps
- Finding and zapping into yield opportunities
How It Works
LI.FI sits between your application and the fragmented liquidity landscape.
You integrate once. LI.FI handles the routing logic and infrastructure maintenance.
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.
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
Without LI.FI vs. With LI.FI
| Without LI.FI | With LI.FI | |
|---|---|---|
| Bridges | Integrate one per chain pair | Covered by a single integration |
| DEX aggregators | Integrate one per ecosystem | Included out of the box |
| Token mapping | Build and maintain manually | Handled automatically |
| Failed transactions | Monitor and recover yourself | Built-in fallback routing |
| New chain support | Re-integrate each time | Continuous expansion by LI.FI |
| Data feeds | Aggregate and map dozens of sources | Unified data layer |
| Maintenance | Ongoing, high overhead | Managed by LI.FI |
| Time to market | Weeks to months per integration | Days |
Next Steps
SDK Integration
Integrate LI.FI into your application using the JavaScript/TypeScript SDK for full control over routes, execution, and token management.
