Ethereum scaling worked, transactions got cheaper, throughput went up & a L2s launched to meet demands. Each one became its own island, separate liquidity, separate deployments, separate bridges that take a cut every time you try to move between them. Gnosis & Zisk, with co-funding from the Ethereum Foundation, announced the Ethereum Economic Zone Rollup Framework at EthCC in Cannes on March 29, 2026. The pitch is to stop building more islands & start connecting the ones already there.

The Fragmentation Problem EEZ Is Built to Solve

If you have ever tried moving assets between two L2s, you already understand the problem better than any whitepaper can explain it. You find a bridge, you approve something, you wait, you wait again on the other side & you end up with slightly less than you started with & no clear sense of where the rest went. Itsn't really a great experience.

For protocols, it is more of a structural headache where Every L2 deployment is a fresh start: new liquidity pools, new bootstrap effort, same users spread thinner across more chains. The deep liquidity sitting on Ethereum mainnet might as well be on a different planet if your users are on a rollup & there is a bridge standing between the two.

Gnosis co-founder Friederike Ernst put it well at EthCC: Ethereum does not have a scaling problem, it has a fragmentation problem. EEZ is the attempt to fix it not by creating yet another isolated environment, but by connecting existing ones into something that actually behaves like a single DeFi economy.

How Synchronous Composability Actually Works

The core idea here is synchronous composability. A smart contract on an EEZ rollup can call a contract on Ethereum mainnet or on another EEZ rollup,inside one atomic transaction. Everything either goes through or everything reverts. No partial outcomes, no bridge exploits in the gap between chains, no wrapped assets carrying extra risk.

Today's bridges are asynchronous, meaning that a transaction on one chain kicks off a separate transaction on another, with a window in between where things can go sideways. Synchronous composability closes that entirely. Same block & same security model as deploying natively on L1.

The ZK proving layer that makes this possible comes from Zisk, founded by Jordi Baylina, who built Circom & was a core contributor to Polygon zkEVM. Zisk's real-time ZK proving stack handles the cross-chain verification without adding any new trust assumptions. ETH is the gas token throughout, so there is no new network token you need to hold to use any of this.

What this looks like in practice: a protocol on an EEZ rollup calls into Uniswap's mainnet liquidity pools in the same transaction as a local operation.
