The Ethereum Foundation's account abstraction team has introduced the Ethereum Interop Layer (EIL) to streamline Layer 2 networks into a cohesive Ethereum chain. This initiative, based on ERC-4337 and trustless declaration principles, enables users to perform cross-chain transactions with a single signature, removing the need for additional trust assumptions or third-party bridges. EIL allows users to initiate and settle cross-L2 operations directly from their wallets, with the system automatically managing routing and asset delivery. The proposal maintains Ethereum's core values of self-custody, censorship resistance, privacy, and verifiability by integrating logic on-chain and into user wallets.
