Ethereum’s Account Abstraction team published a blog post detailing the goals for the Ethereum Interop Layer, which is currently open for testing.
The Interop Layer is an onchain protocol designed to enable users and applications to seamlessly interact with the entire Ethereum ecosystem, adopting a wallet-centric approach to unify the EVM environment.
What if all the L2s felt like a single, unified Ethereum?
No bridges to think about, no chain names to recognize, no fragmented balances or assets, Yoav Weiss wrote.
That’s the vision of the Ethereum Interop Layer (EIL): making Ethereum feel like one chain again — while preserving the trust-minimized, decentralized foundations we all care about.
With the Interop Layer, Ethereum wallets and dapps will be multichain-native by default and new and existing rollups will be automatically compatible.
In practice, this would allow users to transfer assets across the Ethereum environment without knowing what specific chain they’re using, Weiss wrote.
The Interop Layer is powered by ERC-4337 account abstraction, the 2023 proposal that makes it possible for user accounts to behave like smart contracts, and is live for testing.
It could address fragmentation in Ethereum’s Layer 2 roadmap by reducing siloed user ecosystems and liquidity, as developers work toward a more integrated experience.
