Developers from Gnosis and Zisk, backed by the&nbsp;<a href="https://bsc.news/post/what-is-ethereum-eth-how-it-works-explained" rel="noopener noreferrer nofollow">Ethereum</a> Foundation, have&nbsp;<a href="https://x.com/gnosis_/status/2038271124232950223" rel="noopener noreferrer nofollow">proposed</a> a framework called the&nbsp;Ethereum Economic Zone (EEZ) that would allow Ethereum's layer-2 (L2) networks to interact with each other and the mainnet in a single transaction, without using bridges.<h2 id="span-span-strong-what-is-the-ethereum-economic-zone-strong-span-span">What Is The Ethereum Economic Zone?</h2>The EEZ is a proposed technical framework designed to let smart contracts deployed on different rollups execute synchronously across networks. In practical terms, this means a transaction could touch multiple L2s at once, settling back to Ethereum mainnet, without the user or developer needing to manually bridge assets between networks.The development team includes researchers and industry contributors from across the Ethereum ecosystem.At its core, the EEZ aims to replicate the experience of building directly on Ethereum, where all contracts share the same environment and guarantees. It would also retain ETH as the default gas token, avoiding the introduction of new tokens.<h3 id="span-span-strong-why-bridges-are-a-problem-strong-span-span">Why Bridges Are A Problem</h3>Bridges are the current solution for moving assets between Ethereum L2s like&nbsp;<a href="https://bsc.news/post/arbitrum-ethereum-layer-2-analysis" rel="noopener noreferrer nofollow">Arbitrum</a>, Base, and&nbsp;<a href="https://bsc.news/post/optimism-ethereum-layer-2-superchain" rel="noopener noreferrer nofollow">Optimism</a>. They work, but they come with trade-offs: they can be slow, expensive, and have historically been targets for exploits.&nbsp;According to data from&nbsp;<a href="https://l2beat.com/scaling/summary" rel="noopener noreferrer nofollow">L2BEAT</a>, more than 20 active L2 networks currently secure nearly $40 billion in total value, with that liquidity spread thinly across separate environments.The EEZ would remove the need for bridging entirely between participating networks.<h2 id="span-span-strong-why-does-ethereum-s-l2-fragmentation-matter-strong-span-span">Why Does Ethereum's L2 Fragmentation Matter?</h2>Ethereum's scaling strategy has relied on rollups for several years. Rollups are networks that process transactions off the main chain but post data back to it, inheriting Ethereum's security. The problem is that dozens of these networks now operate independently, splitting users, developers, and liquidity across separate ecosystems.As Gnosis co-founder Friederike Ernst said:&nbsp;<blockquote>"Ethereum doesn't have a scaling problem. It has a fragmentation problem. Every new L2 is a silo that makes it harder to seamlessly extend and drive value back to the Ethereum mainnet."</blockquote>The EEZ is designed to address that directly by enabling shared infrastructure and unified liquidity across rollups, reducing duplication and simplifying development.<h3 id="span-span-strong-vitalik-buterin-s-concerns-about-the-rollup-roadmap-strong-span-span">Vitalik Buterin's Concerns About The Rollup Roadmap</h3>The EEZ proposal arrives at a notable moment. In a&nbsp;<a href="https://x.com/VitalikButerin/status/2018711006394843585" rel="noopener noreferrer nofollow">February 3 post</a> on X, Ethereum co-founder Vitalik Buterin wrote that "the original vision of L2s and their role in Ethereum no longer makes sense, and we need a new path," signaling that the ecosystem may need to rethink how rollups fit into Ethereum's long-term scaling model.Buterin has also pointed to centralized sequencers and trusted bridging mechanisms as weak points in the current L2 architecture.His comments drew mixed reactions. Karl Floersch, co-founder of Optimism, acknowledged that L2s must evolve beyond simple scaling. Steven Goldfeder, co-founder of Offchain Labs (the team behind Arbitrum), argued that scaling remains a core function, noting that rollups continue to handle higher transaction throughput than Ethereum mainnet itself.<h2 id="span-span-strong-how-would-the-eez-actually-work-strong-span-span">How Would The EEZ Actually Work?</h2>The framework enables synchronous execution across rollups. That is a technical way of saying that instead of a transaction happening on one network and then triggering a separate process on another, all the steps happen at the same time within a single transaction context.Here is what that looks like in practice for different stakeholders:<ul><li>Users would move between L2 applications without manually bridging assets or switching networks.</li><li>Developers would be able to build once and deploy across multiple rollups without rebuilding the same infrastructure each time.</li><li>Protocols operating across multiple L2s, such as DeFi platforms, would share liquidity pools rather than fragmenting them.</li></ul>The framework leans on zero-knowledge (ZK) proving technology, which is the specialty of Zisk. ZK proofs allow one party to prove that a computation was done correctly without revealing underlying data, and are widely used in modern rollup designs. Zisk was founded by Jordi Baylina, the creator of Polygon zkEVM.<h3 id="span-span-strong-the-eez-alliance-strong-span-span">The EEZ Alliance</h3>The proposal also introduces the&nbsp;EEZ Alliance, a coordination body that would bring together infrastructure providers, DeFi protocols, and other ecosystem participants to standardize how the framework is adopted.The alliance is intended to function as an open group rather than a centralized authority. Technical specifications and performance benchmarks are expected to be published in the coming weeks.<h2 id="span-span-strong-who-is-building-the-eez-strong-span-span">Who Is Building The EEZ?</h2>The framework is being developed by three organizations:<ul><li>Gnosis is a veteran Ethereum infrastructure developer that has been building on the network since its early days. It is best known for the Gnosis Safe multisig wallet and the Gnosis Chain.</li><li>Zisk is a ZK proving project led by Jordi Baylina, who previously created Polygon zkEVM, one of the most widely used ZK rollups.</li><li>The Ethereum Foundation is providing backing and research support for the initiative.</li></ul>The project is being developed collaboratively, with broader community input expected as specifications are finalized.<h2 id="span-span-conclusion-span-span">Conclusion</h2>The Ethereum Economic Zone is a direct response to a problem that has grown alongside Ethereum's own success. More L2 networks have meant more capacity, but also more fragmentation, more bridges, and a worse experience for both users and developers.The EEZ does not add another network to that pile. Instead, it proposes a layer of coordination that makes existing rollups behave like parts of a single system, while keeping ETH as the fee currency and Ethereum as the settlement layer.Whether the EEZ Alliance can bring enough of the ecosystem on board remains to be seen. Technical specifications are still pending, and adoption will depend on buy-in from the same L2 teams whose independence the framework is designed to work around. But with the Ethereum Foundation involved and Vitalik Buterin publicly questioning the current rollup model, the conditions for a rethink are clearly in place.<h2 id="span-span-resources-span-span">Resources&nbsp;</h2><ol><li><a href="https://x.com/gnosis_/status/2038271124232950223" rel="noopener noreferrer nofollow">Gnosis on X</a>: Post on March 29</li><li><a href="https://x.com/VitalikButerin/status/2018711006394843585" rel="noopener noreferrer nofollow">Vitalik Buterin on X</a>: Post on Feb. 3</li><li><a href="https://cointelegraph.com/news/ethereum-builders-propose-economic-zone-to-tackle-l2-fragmentation" rel="noopener noreferrer nofollow">Report by CoinTelegraph</a>: Ethereum builders propose ‘economic zone’ to tackle L2 fragmentation</li><li><a href="https://www.coindesk.com/tech/2026/03/29/new-ethereum-project-aims-to-fix-network-fragmentation-and-improve-user-experience" rel="noopener noreferrer nofollow">Report by CoinDesk</a>: New Ethereum project aims to fix network fragmentation and improve user experience</li></ol>
