10 Best Cross-Chain Liquidity Routing Protocols
1. LI.FI
LI.FI is a cross-chain aggregator that compares bridges and DEXs and picks the best route for you. It supports over 60 blockchains including Ethereum, Solana, Arbitrum, Base, BNB Chain, Polygon and Avalanche. It connects 20+ bridges (Across, Stargate, Hop, etc.) and 30+ DEXs so you can route almost any liquid token.
The fees are the base bridge fee, gas and optionally the integrator fee, which is typically ~0.25% or less. Default slippage is usually 0.5%, adjustable on a per swap basis. Exchange rates are live quotes on all routes so you get the market rate plus the cost of the route. It powers wallets and apps like Jumper.
