The Open Intents Framework (OIF) is an emerging initiative within the Ethereum ecosystem aimed at standardizing and simplifying intent-based transactions to improve interoperability and user experience across Ethereum’s fragmented Layer 2 (L2) landscape. As Ethereum has scaled through rollups and sidechains, the resulting proliferation of chains has introduced challenges like complex bridging, liquidity fragmentation, and poor cross-chain usability. OIF seeks to address these by providing a modular, open-source framework for developers to build intent-based applications efficiently.
What Is the Open Intents Framework?
At its core, OIF is designed to unify Ethereum’s multi-chain ecosystem by enabling “intents”—high-level user goals (e.g., “swap 1 ETH for USDC on the cheapest chain”)—rather than requiring users or developers to specify the exact mechanics of execution (e.g., which bridge or liquidity pool to use). Instead of users navigating the technical complexity of cross-chain interactions, intents allow them to express desired outcomes, which are then fulfilled by specialized entities called “solvers” through various execution pathways.
OIF emerged as a collaborative effort led by contributors from the Ethereum Foundation, Hyperlane, Bootnode, and over 30 other teams across the Ethereum ecosystem, including major L2s like Starknet and Polygon. Launched publicly around February 19, 2025, it’s positioned as a “public good” to reduce fragmentation and enhance developer and user experiences. OIF provides a suite of tools to make intent-based development accessible.

Composable Smart Contracts: The framework includes modular smart contracts, such as the Base7683 contract, which standardizes how intents are defined and executed. It builds on ERC-7683, a proposed Ethereum standard for intent-based transactions, allowing flexibility in settlement mechanisms (e.g., Hyperlane’s Interchain Security Module or Arbitrum’s Broadcast Standard). This modularity means developers can adapt the contracts to support different order types (e.g., limit swaps) or settlement protocols without starting from scratch.
Solvers are off-chain entities that interpret and execute intents, finding the optimal path to fulfill them (e.g., sourcing liquidity or routing transactions). OIF offers a TypeScript-based reference solver that monitors on-chain events, submits transactions, and handles rebalancing. This lowers the entry barrier for teams wanting to deploy solvers, offering protocol-independent features that can be customized. A pre-built, adaptable user interface is included, enabling developers to quickly integrate intent functionality into their frontends without designing from the ground up. This speeds up deployment for dApps or wallets.
Ethereum serves as the foundational blockchain for OIF due to its dominant position in the smart contract and DeFi space. Ethereum’s mainnet and L2s (like Optimism, Arbitrum, and Polygon) form the backbone of decentralized applications. OIF leverages Ethereum’s infrastructure to connect these chains, using its smart contract capabilities to define intents. By building on Ethereum’s ERC standards (e.g., ERC-7683), OIF ensures compatibility across its vast ecosystem, reinforcing Ethereum’s role as the interoperability layer. Ethereum’s mature network, with thousands of nodes and a $300+ billion market cap, provides a trusted base for OIF’s contracts and solvers, balancing scalability with security.
Unlike private blockchains or newer alternatives (e.g., Solana), Ethereum’s established tooling, developer community, and adoption by institutions (like Fidelity’s tokenized fund) make it the logical choice for a framework aiming for broad uptake. Ethereum’s ecosystem struggles to scale seamlessly across L2s. OIF could indirectly benefit companies like Tesla if they explore blockchain for supply chain or payment systems (e.g., tokenized transactions for vehicle purchases), by simplifying cross-chain operations. However, no direct link exists as of now—Musk’s crypto interests lean more toward Dogecoin than Ethereum.
OIF reduces the need to reinvent intent infrastructure, offering pre-built tools that streamline cross-chain dApp development. This could accelerate innovation in DeFi, gaming, or NFT marketplaces. A unified intent system promises a smoother experience—think gasless swaps or one-click cross-chain transfers—without navigating L2 complexities. By standardizing intents, OIF could boost L2 adoption, reduce centralization risks (e.g., solver monopolies), and enhance Ethereum’s competitiveness against rival blockchains.
