LI.FI Solver

LI.FI Solver is LI.FI’s enterprise-grade in-house solver and fast-bridge, purpose-built to rapidly support new chains, bootstrap liquidity routes, and ensure reliable execution in the early stages of chain adoption.

It plays a foundational role in the LI.FI Intents System, acting as a first responder to new routing demand and serving as a fallback when third-party solvers are unavailable.

What Is LI.FI Solver?

At its core, LI.FI Solver is a trusted execution agent that:

• Facilitates liquidity routing across chains and VMs

• Supports fast bridging with low latency and near-instant confirmations

• Participates in intent auctions within the LI.FI Intents System

• Provides guaranteed execution when marketplace solvers are unavailable

It’s designed to fill the gap until third-party solvers onboard and the route becomes self-sustaining via the open solver marketplace.

Why It Exists

In many cases, new chains or routes lack:

• Active solvers

• Deep liquidity

• Pre-established orderflow

Without someone to take the first step, these routes remain inactive — the classic chicken-and-egg problem. LI.FI Solver solves this by bootstrapping intent fulfillment until the market matures.

Once a route gains momentum, LI.FI Solver steps back and lets other solvers compete.

Key Benefits

⚡ Rapid Chain Support

Support for any chain or VM within an hour. This enables projects to go live quickly and benefit from instant cross-chain interoperability via LI.FI.

🔗 Bridging + Swapping

LI.FI Solver can execute multi-leg transactions, including:

• Direct token bridging

• Cross-chain swaps

• Gasless transactions

It ensures users get a seamless experience even on brand new chains.

🛡️ Guaranteed Fulfillment

With LI.FI Solver in place, no order goes unfilled. It acts as a reliable fallback in the early days of chain or route expansion — critical for trust and user retention.

📈 Liquidity Bootstrapping

It provides the initial liquidity and transaction volume that attract third-party solvers to a new route, allowing LI.FI Intents System to scale into a competitive, decentralized solver marketplace.
