PANews reported on November 18th that the Ethereum Foundation's Account Abstraction team proposed the "Ethereum Interoperability Layer (EIL)" solution, aiming to make all Layer 2 networks function like a single Ethereum chain. Based on the ERC-4337 standard and the Trustless Declaration principle, this solution allows users to complete cross-chain transactions with a single signature, without requiring additional trust assumptions. Users can directly initiate and settle cross-Layer 2 operations from their wallets, without relying on relayers or solvers. EIL aims to solve the fragmentation problem of Layer 2 networks, simplify token management and cross-chain transfer processes. Users only need to select assets and addresses, and the wallet will automatically complete inter-chain routing and asset delivery.
