What is the Ethereum Interoperability Layer (EIL)? EIL is a wallet-centric, trustless interop layer for cross-chain execution. The user executes their own transactions, preserving privacy & censorship resistance. To learn more about EIL, read here 👇

EIL is a new approach to L2 interop that removes the "mid-state" trust dependency. Using a relayer or solver for interop today is like buying a bus ticket: the driver knows where you're going, and if they stop mid-route, you're stranded. Using EIL is like buying gas. Liquidity providers sell you what you need to make your call, but they don't know where you're going, and they can't stop you after. Then your own account makes every call on every chain. Check it out! And "Fill 'er up"!

Diving into the rabbit hole of EIL @ethinteroplayer was really fun and I feel like there's many more interesting details to discover about this trust-minimized interop protocol. If you want to do some digging yourself, here's what's going on: 🧵👇

I support EIL. At its core, EIL is fundamentally _Cypherpunk_ because it restores user sovereignty at the interoperability layer. Users sign once & transact directly from their own wallets, _never_ delegate execution, custody, or intent to any intermediaries. It rejects _trusted_ relayers (guys, we need to cut out the centralised deps bloat that keeps getting reintroduced as "infra" every time UX is used as an excuse), opaque solvers & surveillance-heavy infra because trustlessness fucking matters. The execution is local, verifiable & enforced by Ethereum itself. EIL embodies the Cypherpunk ethos: minimise trust, maximise autonomy, and build infra that cannot be captured or censored. Make Ethereum Cypherpunk again!

Thanks @l2beat for the excellent research on EIL 👋 We are looking forward to the L2beat interop framework. EIL was designed with these principles in mind and will be all green 🟢

Great job to @nachfq @cobuildersxyz for building this local EIL playground so devs can experiment with the protocol. If you're interested in building on EIL, you can check this out as an easier quickstart 🚀

The claim that @ethinteroplayer is similar to other solutions that are already live for over a year is totally misleading and wrong. Is the source code open source? No! Then how can you claim it enjoys the same level of trust as EIL?

@ethinteroplayer is the only trustless and permissionless chain abstraction solution that is true to the ethos of @ethereum

EIL turns multichain execution into just transaction execution. If a dapp knows what function it wants to call, it doesn’t matter whether that call happens on Chain A, Chain B, or both because the pattern is identical. This is what account-based interop unlocks 🚀

Come build with the new EIL SDK! @drortirosh and Alex Forshtat from the @ethereumfndn account & chain abstraction team and co-authors of the @erc4337 and @ethinteroplayer protocols will deep dive into EIL and how to use its SDK 3:00 PM, next to the XL stage, Yellow Pavilion

For years we’ve said Ethereum should scale without giving up self-custody, censorship-resistance, or verifiability. Day 1 of trustless:// is the first unveiling of the Ethereum Interop Layer design and architecture. Sign up see the agenda: trustlessconference.com/

Let’s scale ethereum’s trustlessness, not erode it. Come gather with us at @trustlessconf in Buenos Aires on November 18th and 19th at @EFDevcon 🇦🇷🚀

HTTP connected the early internet. EIL connects ethereum’s rollups. One signature. Cross-rollup. Trustless interoperability is here 🚀
