LI.FI

• Name: LI.FI
• URL: https://li.fi/
• Tags: ethereum-ecosystem solana-ecosystem
• Category: Cross-chain routing and execution infrastructure / bridge and DEX aggregation
• Summary: LI.FI is route-orchestration middleware. The useful read is not one API to everything; it is a venue-admission and route-ranking layer that lets wallets and apps outsource multichain execution defaults across bridges, DEXs, solvers, and widgets.
• What it does:
  • Aggregates bridge, exchange, and solver liquidity across multiple blockchain ecosystems behind one integration surface
  • Provides REST APIs, SDKs, and embeddable widgets for swap, bridge, and cross-chain execution flows
  • Calculates routes based on factors such as price, gas cost, speed, and execution reliability
  • Supports multi-step flows including bridge-plus-swap, bridge-plus-deposit, and other cross-chain contract-call patterns
  • Exposes AI-agent-oriented documentation, machine-readable docs, and related tooling for agentic integrations
• Key claims:
  • Docs describe LI.FI as a “routing and orchestration layer” connecting applications to onchain liquidity across chains, bridges, DEXs, solvers, and yield protocols through a single integration
  • Official docs say developers can use one integration for same-chain swaps, cross-chain swaps and bridging, cross-chain contract calls, and multi-step DeFi workflows
  • API docs state the public base URL is https://li.quest/v1 and that most API use cases can be covered with quote, status, chains, tokens, and tools endpoints
  • Agent docs say LI.FI supports 58 blockchains and aggregates 27 bridges plus 31 exchanges in the current documentation pass
  • The GitHub organization and docs show an active product surface spanning SDK, widget, contracts, token lists, and related developer tooling
• Whitepaper: No classic whitepaper or litepaper was found during this pass. Primary-source snapshots were saved in ../whitepapers/li-fi-primary-sources-2026-04-22.md.

Internal linkages

• Best upward reads for route orchestration and hidden-defaults control planes: across, skip, and relay.

• Keep this note on route ranking, venue admission, fallback policy, and integrator defaults rather than pretending LI.FI is peer to every bridge or intent system it can touch.
