A gas-aware cross-chain DEX aggregator routing swaps across 50+ L2s.
LI.FI is a cross-chain liquidity aggregation platform that enables token swaps across multiple blockchains, routing through bridges and DEXs for best execution.
57Blocks built the routing and integration layer behind it — a gas-aware swap engine, broad chain and DEX coverage, and performance controls that keep cross-chain execution fast and cost-efficient at scale.
01Swap routing algorithm
Shortest-path search with gas-cost modeling, supporting both whole and split orders for best-route execution.
02Chain & DEX integrations
Coverage across 50+ L2s, with a structure that accelerates onboarding of new networks.
03Performance & cost controls
Event-driven data refresh and multicall3 batching to cut RPC round-trips and reduce infrastructure load.
Reliable best-route execution for cross-chain swaps, including split-route optimization.
Reduced latency and infrastructure load through fewer RPC calls and event-driven updates.
Shortened time-to-support for new chains via a modular integration pattern.
A foundation to extend routing logic and coverage as new ecosystems mature.
LI.FI continues expanding chain coverage, with 57Blocks supporting ongoing integrations and routing enhancements.
