Making Ethereum Feel Like One Chain Again | Ethereum Foundation Blog

The Ethereum Foundation's Account Abstraction team proposes the Ethereum Interop Layer (EIL), which would make Ethereum's rollups feel like one chain by letting users sign once for a cross-chain transaction without adding new trust assumptions. The proposal builds on ERC-4337 account abstraction and the Trustless Manifesto, with users initiating and settling cross-L2 actions directly from their wallets rather than through relayers or solvers. Examples include a cross-chain USDC transfer from Arbitrum to Base, an NFT mint on Linea funded from Arbitrum and Scroll, and a swap on an Optimism DEX. The article states that the disclaimer applies: the post is a team proposal and may not reflect consensus views of the Foundation.
