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.

Deployments are already live on multiple networks including Ethereum Sepolia and Optimism Sepolia. Under optimal conditions, solver-filled orders complete in 10 to 60 seconds.
