Ethereum processed its first Ethereum Economic Zone transaction between mainnet and an EEZ-connected layer-2 network on Monday, October 5.
The test transferred 0.001 ETH and coordinated a state update across both execution layers.
EEZ contributor Eduardo Antuña Díez announced the transaction and called it the framework’s first atomic L1-to-L2 execution on Ethereum mainnet.
Transaction logs showed a cross-chain call that transferred 0.001 ETH and triggered a state update on the connected rollup.
The transaction demonstrated how EEZ can coordinate actions across Ethereum and an L2 within one execution.
The system allows linked operations to complete together when the required conditions succeed.
The test also showed how EEZ handles state changes across separate execution layers.
A transaction can coordinate activity on Ethereum with activity on a connected rollup without treating each action as an isolated process.
The 0.001 ETH transfer therefore served as a technical test of the execution mechanism rather than a large financial transaction.
EEZ Seeks to Connect Ethereum Fragmented Rollup Economy
Ethereum’s rollups operate as separate execution environments with their own applications, transactions, and liquidity.
This separation can force applications to manage different integrations when they operate across multiple rollups.
Users may also need separate transactions, bridge operations, and waiting periods when they move between Ethereum and different networks.
EEZ allows a connected rollup to call an Ethereum mainnet contract during the same transaction.
A smart contract on an EEZ rollup can receive an Ethereum contract’s response before its transaction finishes.
The framework also plans to let participating EEZ rollups call contracts on other connected rollups.
The design lets applications use one framework for interactions with Ethereum and the participating EEZ rollups.
Applications can therefore access Ethereum contracts and liquidity without creating a separate bridge integration for each connected environment.
Gnosis and Zisk introduced EEZ to address fragmentation across Ethereum’s growing layer-2 ecosystem.
Both organizations serve as founding contributors to the project. The Ethereum Foundation funded the initiative, while a planned Swiss EEZ Association will support its open-source development.
The protocol coordinates an Ethereum transaction with an L2 block so linked operations can execute within one Ethereum block.
If the required conditions fail, the protocol can prevent the linked operations from completing together.
This structure forms the technical basis for EEZ’s planned synchronous interactions across connected networks.
Gnosis Rollout Will Test EEZ Beyond the Demo
EEZ’s core protocol repository describes the project as an early-stage implementation that remains under development.
The repository says developers have not audited the software and may still change its interfaces and storage layouts.
The current implementation computes state off-chain before verifying the resulting state on Ethereum.
The protocol currently limits some cross-rollup calls during specific execution phases. Some calls require participating rollups to complete verification together within the same batch.
Developers have also continued testing block commitments, gas limits, upgrade paths, and fixes for liveness problems.
GnosisDAO approved GIP-153 in August to convert Gnosis Chain from an independent layer-1 into an EEZ rollup on Ethereum.
GIP-153 is targeting genesis for the new Gnosis EEZ network in December 2026 or January 2027.
The proposal would let Gnosis users retain their existing addresses, balances, and application state after the transition.
The first deployment would support atomic L2-to-L1 calls through an interim proving system. Gnosis plans to add bidirectional composability and real-time zero-knowledge proving in later versions.
