A framework, a standard, an intent

As Ethereum’s ecosystem expands with over a hundred L2 networks — such as Arbitrum, Polygon, Optimism and ZKsync — navigating between these networks remains cumbersome. Each transfer is like booking a flight with multiple layovers and different airlines, requiring users to manage chains, navigate bridges and sometimes use multiple wallets.

Intents offer a solution by letting users specify the outcome they want while specialized solvers determine the best way to execute it efficiently. Instead of manually moving assets and interacting with different networks, users simply declare their intent, and solvers handle the rest.

The Open Intents Framework (OIF) is a new initiative designed to standardize and simplify cross-chain transactions within the Ethereum ecosystem. Developed by contributors from the Ethereum Foundation, Hyperlane and Bootnode, OIF provides a modular, permissionless system for intent-based execution. By allowing users to specify desired outcomes rather than manually executing transactions across multiple L2s, OIF aims to smoothen the rough edges of cross-chain interoperability.

Using standardized infrastructure, developers can integrate intent-based execution without needing to build proprietary solutions from scratch. This shared framework reduces friction and fosters collaboration across some 30 ecosystem teams.

A key feature of OIF is its support for multiple settlement mechanisms that allow developers to choose execution methods that best suit their use cases. These include:

• RRC-7755 from Base and Hashi Alliance: An oracle aggregator ensuring reliable data for cross-chain execution.
• Espresso Systems’ confirmation layer: A mechanism adding additional security and finality assurances.
• Optimism’s Superchain native interoperability: A framework enabling seamless interactions within the Optimism ecosystem.
• Arbitrum’s broadcast standard: A protocol optimizing intent execution on the Arbitrum network.

This diversity in settlement methods allows builders to experiment with different approaches while maintaining interoperability.

ERC-7683: Standardizing cross-chain intents

At the core of OIF is ERC-7683, a standard developed by Across and Uniswap Labs to create a unified structure for expressing and executing intents across Ethereum’s expanding ecosystem.

Unlike EIPs, Ethereum requests for comments (ERCs) focus on application-layer standards, such as token specifications and execution frameworks. ERC-7683 functions as a shared language that ensures compatibility across solvers, users and applications to eliminate fragmentation.

OIF lowers barriers for all participants in Ethereum’s multichain space:

• Developers save months of development time by using ready-made infrastructure.
• Networks can integrate intent-based execution without needing permission from central authorities.
• Users benefit from near-instant cross-chain transactions, dramatically improving efficiency.
• Solvers can service multiple protocols under a single framework, streamlining their operations.

With support from Ethereum’s major L2s and infrastructure providers, the OIF represents a coordinated effort to unify Ethereum’s multichain environment, reminiscent of the W3 Alliance. As adoption grows, it is expected to drive the next phase of interop, making intent-based execution a core component of the ecosystem.
