• Making Ethereum Feel Like One Chain Again Posted by Yoav Weiss and Account & Chain Abstraction Team on November 18, 2025 Research & Development Disclaimer: The following blog is a proposal from the Account Abstraction team. • Content may not imply consensus views, and the EF is a broad organization that includes a healthy diversity of opinion across Protocol and beyond that together strengthen Ethereum. • Since the early days of Ethereum, the promise has always been bold: a global, permissionless, censorship-resistant computing platform. • Today, that promise is more alive than ever. • Ethereum has scaled through rollups, where blockspace is abundant and transactions are cheap. • The challenge now is not just throughput, butseamless user experienceacross that multichain horizon.
Article Summaries:
- The Account Abstraction team proposes the Ethereum Interop Layer (EIL), a new account‑based interoperability framework that would make all Layer‑2 rollups feel like a single, unified Ethereum chain. EIL uses ERC‑4337 account abstraction and the Trustless Manifesto to let users sign one cross‑chain transaction directly from their wallet, eliminating the need for bridges, relayers, or manual integration of each L2. The goal is to preserve Ethereum’s core guarantees-self‑custody, censorship resistance, and on‑chain verifiability-while providing a seamless, wallet‑centric user experience across all rollups. The proposal emphasizes that this unification should not introduce new trust assumptions, aiming to reduce cognitive overhead and friction for end‑users.
