Making Ethereum Feel Like One Chain Again

Disclaimer: The pursuing blog is simply a connection from the Account Abstraction team. Content whitethorn not connote statement views, and the EF is simply a wide enactment that includes a steadfast diverseness of sentiment crossed Protocol and beyond that unneurotic fortify Ethereum.

Since the aboriginal days of Ethereum, the committedness has ever been bold: a global, permissionless, censorship-resistant computing platform. Today, that committedness is much live than ever. Ethereum has scaled done rollups, wherever blockspace is abundant and transactions are cheap. The situation present is not conscionable throughput, but seamless idiosyncratic experience crossed that multichain horizon.

What if each the L2s felt similar a single, unified Ethereum?

No bridges to deliberation about, nary concatenation names to recognize, nary fragmented balances oregon assets.

That’s the imaginativeness of the Ethereum Interop Layer (EIL): making Ethereum consciousness similar 1 concatenation again — portion preserving the trust-minimized, decentralized foundations we each attraction about.

EIL makes Ethereum’s rollups consciousness similar a single, unified concatenation by enabling users to motion erstwhile for a cross-chain transaction without adding caller spot assumptions. Built connected ERC-4337 relationship abstraction and the principles of the Trustless Manifesto, users themselves initiate and settee cross-L2 actions straight from their wallets, not done relayers oregon solvers. EIL preserves Ethereum’s halfway guarantees of self-custody, censorship resistance, disintermediation, and verifiable onchain execution. This caller account-based interoperability furniture unifies Ethereum’s fragmented L2 ecosystem nether Ethereum’s ain information model.

The problem: fragmentation astatine scale

L2 chains person brought melodramatic gains successful throughput and cost-efficiency. Yet they’ve introduced a caller benignant of complexity for users and wallets:

• Which concatenation is my token on?
• How bash I determination tokens from Arbitrum → Base → Scroll → Linea?
• Do I request to spot a third-party span oregon relayer?
• Does my wallet oregon dapp request to manually integrate each caller chain?

From a user’s perspective, the effect is little Ethereum and much multiple abstracted Ethereums. You’re managing chains, not simply transacting. That creates friction, cognitive overhead, and often vulnerability to further spot assumptions — bridges, relayers, solvers — on with accrued censorship risk.

The vision: galore L2s, 1 Ethereum

Imagine this instead:

You unfastened your wallet, take an plus and an address, and deed Send.

Your wallet figures retired which concatenation it’s connected and however to present the plus — down the scenes.

You mint an NFT, determination tokens, commercialized assets — and it doesn’t substance which rollup you oregon the counterparty are on, oregon wherever the dapp is deployed.

New networks articulation the ecosystem, and your wallet just works with them — nary customized integrations, nary reliance connected off-chain operators.

That’s EIL. It’s astir wallet-centric multichain UX: the wallet becomes your cosmopolitan model into the Ethereum ecosystem, and the web feels similar 1 seamless acquisition alternatively than a patchwork of islands.

In a sense, EIL is to Ethereum what HTTP was to the aboriginal Internet.

Before HTTP, users could link to idiosyncratic servers — but not seamlessly harvester them successful 1 flow.

HTTP unified the experience, letting browsers traverse servers effortlessly.

EIL aims to bash the aforesaid for Ethereum’s rollups: bringing Ethereum into its “web era”, wherever wallets enactment similar browsers and users navigate freely crossed L2s without friction.

What it takes: spot assumptions, preserved

Unity of UX is compelling — but lone if it doesn’t compromise Ethereum’s halfway values:

• Self-custody: users clasp their assets and initiate transactions themselves.
• Censorship-resistance: nary intermediary tin artifact oregon hold your transaction.
• Privacy: you don’t person to uncover your IP code oregon intentions to a relayer oregon solver.
• Verifiability: immoderate logic that matters tin beryllium checked onchain oregon successful open-source wallet code.

EIL was designed according to the trustless manifesto. It moves the logic onchain and into the user’s wallet, removing dependence connected intermediaries and opaque server logic. Users transact straight connected each chains; trustless liquidity providers proviso funds but ne'er interact straight with users, nor spot their transactions.

Instead of “I spot a span relation to determination my funds,” you get “my wallet and declaration bash it — nether verifiable rules.”

The spot bound remains minimal.

Ethereum is astir disintermediation — interop should beryllium arsenic well

Ethereum’s large innovation is replacing intermediaries with verifiable code.

Crypto erstwhile depended connected centralized exchanges (CEXs) until Ethereum made decentralized exchanges (DEXs) imaginable — nary request to spot a custodian, nary counterparty risk, conscionable a verified astute contract. DeFi changed the satellite by offering an intermediary-free alternate to TradFi.

Cross-L2 interop inactive resembles a CEX model, with span operators, relayers, solvers, and opaque off-chain infrastructure.

Transacting crossed L2s should beryllium arsenic trustless arsenic utilizing a DEX.

EIL moves the logic onchain and into the user’s wallet, removing dependence connected intermediaries and opaque server logic. Users transact straight connected each chains; trustless liquidity providers proviso funds but ne'er interact straight with users, nor spot their transactions.

From the user’s view: however it feels

• Cross-chain transfer — Alice has USDC connected Arbitrum, Bob is connected Base.
  In 1 click, her wallet executes a transportation to Bob’s Base address. From Alice’s constituent of view: “Send USDC to Bob” — she doesn’t attraction which web it happens on.

• Cross-chain mint — Alice holds ETH connected Arbitrum and Scroll. She wants to mint an NFT connected Linea.
  Her wallet automatically consolidates balances and handles inter-chain state and plus question transparently. One click, 1 signature.

• Cross-chain swap — Alice finds amended liquidity for her token connected an Optimism DEX.
  She swaps from Arbitrum, her wallet handles the path, and she ends up backmost connected Arbitrum with her caller token — nary bridging, nary manual steps.

For the idiosyncratic it’s: “Send, mint, swap — I conscionable bash what I want.”
Behind the scenes it’s: “Wallet + onchain protocol transact crossed chains — nary caller spot requirements.”

Why this matters for the ecosystem

When interoperability becomes a wallet-level capability alternatively of an app-by-app integration, the full ecosystem advances:

• Wallets and dapps go multichain-native by default.
• New rollups are automatically compatible, accelerating adoption.
• Developers tin absorption connected gathering large experiences, not wiring up cross-chain plumbing.
• Users reclaim the simplicity of Ethereum: 1 wallet, 1 signature, galore chains — 1 experience.
• Most importantly, Ethereum’s trust-minimized exemplary remains intact without caller intermediaries.

This brings america person to the archetypal promise: a satellite machine that is global, open, seamless and trustless.

The bottommost line

Ethereum has already scaled. What’s lagged is the feeling of unity.

The Ethereum Interop Layer is the adjacent measurement toward that unity — wherever your wallet is your portal, and each rollup feels similar Ethereum’s autochthonal hold alternatively than a abstracted silo.

We invitation wallet teams, dapp builders, web designers, and the broader ecosystem to articulation this journey.
Together, we tin marque Ethereum not conscionable scalable — but seamlessly singular.

Let’s marque Ethereum consciousness similar 1 concatenation again.
