EEZ Tests First Atomic L1-to-L2 Transaction on Ethereum

EEZ contributor Eduardo Antuña Díez has demonstrated the first atomic cross-chain transaction between the Ethereum mainnet and a layer-2 network, carrying 0.001 Ether (ETH). The test marks a key step in the project's development of a framework designed to connect Ethereum and its rollups without relying on traditional bridges.

Atomic Cross-Chain Execution

In an atomic transaction, linked actions across different networks either all succeed or are completely reversed if any part of the process fails. According to Cointelegraph, the transaction logs recorded a cross-chain call carrying 0.001 ETH alongside a state update for a rollup.

Unifying Ethereum Liquidity

The Ethereum Economic Zone (EEZ) framework aims to reconnect liquidity and applications that are currently fragmented across separate layer-2 networks. In March, developers behind the project stated that the framework is designed to allow rollups to interact with each other and the Ethereum mainnet within a single transaction.

Gnosis co-founder Friederike Ernst previously noted that the lack of synchronous composability forces protocols to maintain separate deployments across layer-2 networks, which fragments liquidity. Jakub Gregus, co-founder of decentralized finance protocol Hydration, described the demonstration as a major milestone that could directly benefit the Ethereum ecosystem.
