Built Gas-Aware Cross-Chain DEX Aggregator Across 50+ L2s
#CrossChain  #DEXAggregator

Li.Fi is a cross-chain liquidity aggregation platform that enables token swaps across multiple blockchains by routing through bridges and DEXs for best execution.

What 57Blocks Delivered

Swap Routing Algorithm: Shortest-path search with gas-cost modeling; supports whole and split orders.

Chain & DEX Integrations: Coverage across 50+ L2s with a structure that accelerates onboarding of new networks.

Performance & Cost Controls: Event-driven data refresh; multicall3 to cut RPC round-trips.

Tech Stack: Viem, Node.js.

Business Impact

Enabled 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.

Established a foundation to extend routing logic and coverage as new ecosystems mature.

Current Status

Li.Fi continues expanding chain coverage with 57Blocks supporting ongoing integrations and routing enhancements.
