The Ethereum Economic Zone, or EEZ, has tested what a project contributor described as the first atomic cross-chain transaction from Ethereum layer 1 to layer 2. On Tuesday, contributor Eduardo Antuña Díez shared the transaction and said its logs showed a cross-chain call carrying 0.001 ETH along with a rollup state update. In this setup, all linked actions must complete together, or the entire transaction is reversed if one part fails.
EEZ said in March that its framework is meant to let rollups interact with each other and with Ethereum mainnet inside a single transaction, without using bridges. The stated goal is to reconnect liquidity and applications that are currently spread across separate L2 networks. The project is aimed at a long-running issue in Ethereum scaling: fragmented deployments and fragmented liquidity across multiple rollups.
Cointelegraph also cited comments from Gnosis co-founder Friederike Ernst, who said the lack of synchronous composability forces protocols to maintain separate deployments across L2s, splitting liquidity into multiple markets. Hydration co-founder Jakub Gregus called the demonstration one of crypto’s most important milestones and said the technology could directly benefit Ethereum.
The Ethereum Economic Zone (EEZ) has tested an atomic transaction between Ethereum mainnet and a layer-2 network, according to a project contributor, as the initiative works on a framework meant to connect Ethereum L1 with its rollups.
On Tuesday, EEZ contributor Eduardo Antuña Díez shared the transaction and described it as the first atomic cross-chain L1-to-L2 transaction. The transaction logs show a cross-chain call carrying 0.001 Ether (ETH) and a state update for a rollup.
What the test showed
In an atomic transaction, linked actions across networks either all go through or all get reversed if any part fails.
EEZ developers said in March that the framework was designed to let rollups interact with one another and with Ethereum mainnet within a single transaction, without relying on bridges. The project’s stated aim is to reconnect liquidity and applications that are spread across separate L2 networks.
The fragmentation problem EEZ is targeting
Cointelegraph cited earlier comments from Gnosis co-founder Friederike Ernst, who said the lack of synchronous composability forces protocols to maintain separate deployments across L2s, fragmenting liquidity into multiple markets.
Jakub Gregus, co-founder of decentralized finance protocol Hydration, called the demonstration “one of the most important milestones” in crypto and said the technology could directly benefit Ethereum.
