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
