The Ethereum Foundation proposes the Ethereum Interop Layer to reduce L2 fragmentation via ERC-4337 account abstraction


TL;DR: Ethereum’s Account Abstraction team proposes the Ethereum Interop Layer (EIL) — a trustless, wallet-centric system that makes all L2s feel like one unified chain. Users can sign once and perform cross-chain transfers, swaps, or mints directly from their wallet with no bridges, relayers, or chain-specific steps. EIL keeps core Ethereum values (self-custody, censorship resistance, verifiability) while moving all logic onchain. The goal: one signature, one wallet, many L2s — a seamless Ethereum experience without fragmentation.
