The Ethereum Economic Zone (EEZ), a rollup framework built by Gnosis and Zisk with co-funding from the Ethereum Foundation (EF), has executed what its contributors describe as the first atomic cross-chain transaction from Ethereum Layer 1 (L1) to a Layer 2 (L2) on mainnet.
The test arrived in the same news cycle as the Glamsterdam upgrade’s scheduled activation on the Sepolia testnet, while Ethereum’s native token, Ether (ETH), held near $2,700.
What Happened on Ethereum Mainnet
EEZ core contributor Eduardo Antuña announced the transaction in a post on X on October 5, 2026. He said atomic synchronous composability had moved beyond theory and was now live on Ethereum mainnet. The project’s official X account shared the milestone the same day, calling it the “first atomic cross-chain L1->L2 transaction ever.”
The on-chain record shows a successful call that moved 0.001 ETH alongside a rollup state update. It was a technical proof transaction, not a retail transfer or a live product launch.
How an Atomic L1-to-L2 Transaction Works
Layer 1 refers to the Ethereum mainnet, the base blockchain that settles transactions. Layer 2 networks, also called rollups, process transactions off the main chain and post the results back to Ethereum to lower fees and raise throughput.
In a standard bridge transfer between the two layers, funds can sit in a contract while one side waits for the other to confirm. That waiting period is where delays, exit risk, and stranded funds can appear.
An atomic transaction removes that gap. The Layer 1 call and the Layer 2 update either both execute or both revert, with no partial outcome. In the EEZ design, a cross-chain call is routed through a proxy, simulated, and packed into a special sync block tied to a single Ethereum block. The bundle is then submitted to an EEZ contract on Layer 1, so the full set of operations lands in the same block under Ethereum’s own block ordering.
This is what the project calls synchronous composability: smart contracts on a connected rollup and on Ethereum mainnet can call each other inside one coordinated transaction. The stated goal is to reduce liquidity fragmentation across the growing number of Ethereum Layer 2 networks.
Who Is Building the Ethereum Economic Zone
Gnosis co-founder Friederike Ernst and Zisk founder Jordi Baylina introduced the Ethereum Economic Zone on March 29, 2026, at the Ethereum Community Conference (EthCC) in Cannes, France. The framework relies on Zisk’s real-time zero-knowledge (ZK) proving technology, uses ETH as its default gas token, and introduces no new token.
The framework targets based rollups, which rely on Ethereum’s block builders for transaction ordering rather than a separate sequencer. Participating rollups must accept Ethereum’s final authority over execution order, a trade-off not every Layer 2 team may choose to make.
The October 5 transaction is a first mainnet demonstration, not the finished network. Earlier project timelines placed the first production EEZ rollup, tied to Gnosis Chain’s planned transition, around December 2026 or January 2027.
Glamsterdam Upgrade Is a Separate Milestone
Glamsterdam is Ethereum’s next network upgrade after Fusaka. It combines the Amsterdam execution layer changes with the Gloas consensus layer changes, and is tracked under Ethereum Improvement Proposal (EIP) 7773.
Its headline features are enshrined proposer-builder separation (ePBS) under EIP-7732, which moves block building arrangements into Ethereum’s core protocol, and block-level access lists under EIP-7928, which record which accounts and storage a block touches so clients can process transactions more efficiently. The upgrade also adjusts gas pricing to better reflect the cost of execution and state growth.
The Ethereum Foundation scheduled the Sepolia activation for epoch 353,024, slot 11,296,768, at 13:53:36 UTC on October 6, 2026. The same announcement said activation dates for the Hoodi testnet and mainnet have not been decided. Ahead of the fork, consensus client Prysm shipped a patch setting a 200 million gas default for Sepolia, part of a broader push toward a 200 million gas limit.
Glamsterdam did not execute the EEZ transaction. One is a protocol-level testnet fork. The other is an application-layer cross-chain test already recorded on mainnet.
Ethereum Price Today: Will ETH Reach $3,000?
ETH traded at $2,708.84 at the time of writing, down 0.6% over 24 hours, according to CoinGecko data. The token moved between $2,680.92 and $2,733.19 during the session, with 24-hour trading volume near $10.49 billion.
A move from current levels to $3,000 would require a gain of about 10.7%. That is achievable in a broad risk-on week, but it does not follow from a 0.001 ETH test transaction or a testnet fork.
Institutional flows remain the bigger near-term factor. ETH held the $2,700 level despite about $155 million in net outflows from U.S. spot Ethereum exchange-traded funds (ETFs) over four sessions. Glamsterdam’s capacity gains will only matter for the network after mainnet activation, stable client performance, and real usage, none of which are live today.
For now, $2,700 is the level in play. Traders are likely to watch $3,000 as a psychological level if ETF flows turn positive, broader crypto demand returns, and the Glamsterdam rollout proceeds without major issues.
What Comes Next
For the Ethereum Economic Zone, the next test is a production rollup handling real applications and liquidity, not another demonstration transaction. For Glamsterdam, the next milestones are Sepolia stability, a Hoodi testnet date, and a confirmed mainnet slot.
