LI.FI Intents System

Coming Soon

LI.FI Intents System

The LI.FI Intents System is a permissionless, modular intents protocol powering next-generation cross-chain execution. It transforms LI.FI from a pure liquidity aggregator into a hybrid system that combines aggregation with a competitive solver marketplace — delivering the best price execution at scale.

Why Intents?

As the crypto ecosystem fragments across hundreds of chains and virtual machines, routing liquidity efficiently becomes increasingly complex. Intents provide a way to express desired outcomes rather than imperative instructions, enabling solvers (third-party executors) to compete in fulfilling them.

The LI.FI Intents System abstracts complexity from users and developers by:

  • Outsourcing execution to permissionless solvers

  • Supporting gasless transactions

  • Enabling chain abstraction through generalized, trust-minimized execution

  • Ensuring fast finality across VMs and ecosystems


Core Principles

The LI.FI Intents System is built around four core architectural principles:

  • Extensible: Works across all VMs and is easy to deploy to new chains.

  • Modular: Every component (e.g., solver, oracle, verification system) is pluggable and upgradable.

  • Permissionless: Anyone can participate as a solver or verifier. No gatekeepers.

  • Trust-minimized: Trust is anchored in the verification system — not in individual solvers.


Key Features

🔁 Competitive Execution

Solvers compete in an open marketplace for LI.FI’s orderflow, tapping into a wide range of liquidity:

  • On-chain DEXs

  • Off-chain sources (e.g., CEXs, OTC desks)

  • Native inventory

💸 Gasless Transactions

Users can pay gas in their input tokens, removing the burden of managing gas tokens on multiple chains.

🧠 Solver-Aware Aggregation

The system enhances traditional aggregation by including solver quotes alongside AMMs and bridges, always selecting the most cost-effective path.

⚡ Rapid Settlement

Solvers are reimbursed within ~30 minutes on average, reducing capital inefficiency and improving order flow reliability.


LI.FI Intents System as the Settlement Layer

The LI.FI Intents System also acts as a generic settlement layer for intents in resource-locked environments (e.g., smart accounts, abstracted wallets). It is compatible with any verification mechanism, including:

  • ZK/storage proofs

  • Interop protocols

  • Off-chain signature servers


LI.FI Solver & Glacis Integration

The Intents System works alongside other components of the LI.FI 2.0 stack:

  • LI.FI Solver: An in-house enterprise solver and fast-bridge for instant chain support and bootstrapping new routes.

  • Glacis: Aggregates interop token standards like OFT, NTT, and CCT to support mint/burn-based token bridging and slippage-free routes.

These tools help solvers rebalance capital efficiently and extend the network’s liquidity coverage.


Use Cases

  • Cross-chain swaps with optimal pricing

  • Gasless onboarding for new users

  • Chain abstraction through smart intent fulfillment

  • Intent-based dApps using generalized execution logic
