what's Eth Interop Layer?
Eth Interop Layer is a protocol designed to solve Ethereum's interoperability challenges at the user experience layer. It enables seamless cross-chain interactions across Ethereum ecosystems, making multi-chain operations feel as intuitive and simple as single-chain usage. By focusing on UX improvements, it addresses fragmentation in the Ethereum stack, allowing users to interact with L2s and other chains without complex bridging or switching. The protocol achieves near-instantaneous interoperability, targeting 1-block latency for trustless cross-chain messaging and actions. It leverages Ethereum's security model to provide fast, secure communication between rollups and chains, reducing reliance on centralized sequencers or slow finality gadgets. This positions it as a key primitive for unified Ethereum liquidity and composability.
L2BEAT outlined the Ethereum Interop Layer (EIL) as a framework to unify Ethereum's L2 ecosystem for a seamless user experience between December 18th and 24th, 2025.
