On March 29, 2026, at EthCC in Cannes, Gnosis co-founder Friederike Ernst and Zisk founder Jordi Baylina unveiled the Ethereum Economic Zone (EEZ) — a new rollup framework designed to solve Ethereum’s L2 fragmentation problem.
The core goal of EEZ is to enable synchronous composability: smart contracts on connected rollups can call contracts on Ethereum mainnet or other EEZ rollups in a single atomic transaction, with the same security and finality guarantees as if everything were on L1. It uses ETH as the default gas token and requires no additional bridges.
The initiative is co-funded by the Ethereum Foundation, a notable endorsement given the Foundation’s recent shift toward leaner spending and a focus on L2 interoperability.
Founding members of the EEZ Alliance include:
Ethereum has seen rapid L2 growth, but this has led to liquidity fragmentation and poor user experience. EEZ joins other efforts like Optimism’s Superchain, Polygon’s AggLayer, and the Ethereum Foundation’s own Interop Layer, but differentiates itself through real-time synchronous composability.
GnosisDAO had already been discussing a potential transition of Gnosis Chain into a natively integrated Ethereum L2 with synchronous composability since February 2026. The EEZ appears to be the concrete outcome of that exploration.
