LI.FI Intents System standardizes cross-chain workflows—enabling efficient, composable integration for engineers through unified intent expression, settlement, and verification.
LI.FI Intents System is an intent marketplace where solvers compete to fulfill users’ token transfers across different blockchains. Built specifically for wallets and applications using resource locks, LI.FI helps deliver better prices and faster settlement times for cross-chain transactions.LI.FI Intents is a part of the Open Intents Framework (OIF), an open-source initiative led by the Ethereum Foundation to create permissionless interoperability and unify the crypto user experience.
An intent protocol allows users to express what they want to accomplish (e.g., “transfer 100 USDC from Ethereum to Polygon”) without specifying exactly how it should happen. The protocol then finds the best way to fulfill this intent through a competitive marketplace of solvers.Solvers are specialized third parties who fulfill cross-chain intents using their own capital and liquidity sources. They compete to offer users the best prices for moving assets between blockchains.Think of LI.FI Intents like Uber for cross-chain transfers: Users request a service (moving tokens across chains), and qualified providers (solvers) compete to offer the best price and service.
Resource locks are smart contracts that securely hold user funds until specific conditions are met. They act as escrow accounts, ensuring that users’ assets remain safe until their cross-chain transaction is properly executed.You can find more information about resource locks in the knowledge database.
