The Ethereum Foundation has unveiled a multi-pronged plan to make transactions across its sprawling Layer 2 ecosystem feel as seamless as using a single blockchain. In a blog post dated 29 August, the organisation introduced the Open Intents Framework (OIF), a set of modular smart-contract components that let wallets and applications route user orders across different rollups without exposing them to bridging steps or additional trust assumptions. Central to the effort is ERC-7683, a proposed interoperability standard now live in production contracts. The specification supports cross-chain swaps, trustless messaging and liquidity rebalancing, and has been reviewed by contributors from Across, Uniswap, LI.FI and OpenZeppelin. Initial integrations target Arbitrum and Coinbase-backed Base, with other rollups able to deploy compatible “solver” modules immediately. The Foundation said the work is part of a broader “Improve UX” programme that also includes the Ethereum Interoperability Layer, shorter Layer 1 slot times and faster settlement windows for optimistic rollups. Complete open-source implementations of OIF are slated for audit completion in the current quarter, with full reference solvers and cross-chain validation modules expected in the fourth quarter of 2025.
