What is Li.Fi?
Li.Fi is a cross-chain bridge and DEX aggregator that finds the optimal route to swap and bridge tokens across 30+ blockchain networks in a single transaction. Instead of manually choosing bridges (Across, Stargate, Connext, etc.), Li.Fi's smart routing algorithm automatically selects the fastest and cheapest path.
🌐Ecosystem Watch
Ecosystem strength is the best leading indicator of L1/L2 value. We track developer activity, unique addresses, and TVL growth — not just token price.
No wrapped assets, no fragmented liquidity—just one wallet connection to the entire multichain ecosystem.
Key Features
Multi-Chain Support
Swap across Ethereum, Polygon, Arbitrum, Optimism, Base, Solana, Avalanche, and 20+ more.
20+ Bridge Integration
Stargate, Across, Connext, Hyphen, Axelar, and more integrated for route optimization.
Smart Routing
Algorithmic path selection for lowest gas, fastest speed, or best rates.
Gasless Bridging
Some routes offer sponsored gas for specific chains (like Across on select pairs).
Widget & SDK
Embed Li.Fi directly in your dApp or use the API for custom integrations.
Jumper.Exchange
Web UI for individual traders seeking the best cross-chain swap routes.

⚠️ Risks to Know
Smart contract risk: Li.Fi aggregates third-party bridges; bugs in any integrated bridge affect users.
Bridge liquidity risk: Routes depend on liquidity in destination bridge pools. Slippage can occur in low-liquidity routes.
Bridge delays: Some routes (e.g., Across, Connext) have message finality delays; tokens arrive after several minutes/hours.
