Launched in February 2025 by the Ethereum Foundation in collaboration with Hyperlane and Bootnode, the Open Intents Framework (OIF) is gaining traction as shared infrastructure for building and executing cross-chain intents. With backing from over 30 teams, including heavyweights like Arbitrum, Optimism, Polygon, ZKsync, and Starknet, the project is positioning itself as a neutral standard rather than a proprietary product.
What the framework actually does
OIF provides the toolkit for cross-chain intents to work across multiple chains. It includes smart contracts, open-source solvers, aggregators, and an SDK that developers can plug into without asking anyone’s permission. The core architecture relies on three key contract types: InputSettler, OutputSettler, and Oracle contracts, along with an interoperability SDK that ties them together.
The framework builds on the ERC-7683 standard, which defines how cross-chain intents should be structured. When a user submits an intent, say a cross-chain token swap, competitive solvers race to fulfill that request as efficiently as possible.
