Ethereum Foundation unveils Ethereum Interop Layer to unite L2 ecosystem
The Ethereum Foundation today introduced the Ethereum Interop Layer (EIL), a proposed framework intended to address growing fragmentation in the Layer 2 landscape as networks scale for higher throughput and lower fees. EIL is designed to standardize cross-rollup messaging, streamline asset transfers and tooling, and offer a common approach developers and operators can adopt to improve composability and user experience across disparate L2 designs.
If widely adopted, the proposal could reduce bridging risk, simplify developer stacks, and make DeFi and on-chain applications more seamless for end users — a practical step toward broader ETH scalability. The plan remains a proposal that will require specification work and community coordination, so timelines and adoption depend on buy-in from rollup teams, infrastructure providers, and ecosystem stakeholders.
