TechFlow, November 18 — According to a disclosure on the official Ethereum Foundation blog, the Ethereum Foundation's Account Abstraction team has formally proposed the "Ethereum Interop Layer (EIL)" solution, aiming to make all layer-2 networks feel like a single, unified Ethereum chain.
Built upon the ERC-4337 account abstraction standard and the principle of trustless declarations, this solution enables users to complete cross-chain transactions with a single signature without introducing new trust assumptions. Users can initiate and settle cross-layer-2 operations directly from their wallets, eliminating reliance on relayers or solvers.
EIL aims to address current fragmentation issues across layer-2 networks, including the need for users to manage token locations across multiple chains, complex cross-chain transfer processes, and dependence on third-party bridging services. With this solution, users simply select assets and an address in their wallet and click send; the wallet will then automatically handle inter-chain routing and asset delivery.
The team stated that EIL preserves Ethereum’s core values—self-custody, censorship resistance, privacy protection, and verifiability—by moving logic on-chain and into user wallets, thereby removing dependency on intermediaries.
