According to ChainCatcher, the Ethereum Account Abstraction team has released a proposal for the "Ethereum Interoperability Layer" (EIL), which aims to make all L2 blockchains as seamless as if they were on the same chain.
EIL, based on ERC-4337, allows users to complete cross-chain operations with a single signature within their wallet, without the need for cross-chain bridges or relays, while maintaining self-custody and censorship resistance, enabling a unified experience across the Ethereum multi-chain ecosystem.
