EEZ’s first atomic L1-to-L2 call moves just 0.001 ETH

On October 5, the Ethereum Economic Zone (EEZ) transferred 0.001 ETH from Ethereum’s base chain to a layer-2 network in a single atomic transaction.

The run was a demo. EEZ has not shipped a product and nothing has changed in the protocol of Ethereum.

Two-way calls, nested calls across chains, and real-time proving are still on the roadmap as work running through 2027. The core software of EEZ is still in its infancy.

Etherscan logs the transfer in block 26,127,444 for an $0.80 fee

Etherscan shows the transaction was confirmed in block 26,127,444 at 16:44 UTC.

The 0.001 ETH, around $2.70, was sent to a contract called “EEZ: Cross Chain Proxy.” The fee was about $0.80. And in the same all-or-nothing move, a rollup’s state changed as well.

If any linked action fails, all actions are rolled back. So the L1 transfer and L2 update either both happen together or none happen at all.

The transaction was posted on X by Eduardo Antuña Díez, a core engineer on the EEZ project. “Atomic synchronous composability is no longer a promise,” he wrote.

He dubbed it “the first atomic cross-chain L1->L2 transaction ever,” adding: “And this is only the beginning for EEZ.”

Prior to the mainnet run, the team conducted an audit, tested live blob encoding and ran the system against CoW Swap and Uniswap v4.

Gnosis and Zisk aim to rejoin liquidity split across rollups

EEZ is run by Gnosis and Zisk and is bolstered by the Ethereum Foundation. The project started in early 2026 and in March sketched a design for rollups and mainnet to call each other in a single transaction, with no bridge in between.

Its target is liquidity split across Ethereum’s many L2s. According to Gnosis co-founder Friederike Ernst, protocols would have to keep separate deployments on each L2 without synchronous composability.

Cryptopolitan reported in November 2025 that the Ethereum Foundation is also working towards the same goal with its Ethereum Interop Layer, which it said would make Ethereum “feel like one chain again.” Built on ERC-4337 account abstraction, it lets users sign once for a cross-chain transaction.

In February, Vitalik Buterin said that the “original vision of L2s and their role in Ethereum no longer makes sense,” Cryptopolitan reported. He said L2 progress, “secondarily, on interop,” had been “far slower and more difficult than originally expected.”

The reaction on X was hot. DeFi protocol Hydration co-founder Jakub Gregus ranked the demo among the most important milestones of crypto and said it could directly benefit ETH. “I told you couple months ago I am becoming increasingly bullish on Ethereum as technology,” he wrote.

Another user said that EEZ “one-shotted Ethereum’s biggest problem.” But a single 0.001 ETH call in one direction leaves most of the work for the 2027 roadmap.
