A collaborative team of developers from Gnosis and Zisk, with support from the Ethereum Foundation, has introduced a ambitious new framework designed to address a critical challenge facing Ethereum: the fragmentation of its growing layer-2 ecosystem. Their proposal, called the “Ethereum Economic Zone” (EEZ), aims to enable seamless, synchronous interaction between smart contracts deployed on different rollup networks and the Ethereum mainnet—all within a single transaction and without relying on traditional cross-chain bridges.
Announced in a release shared with Cointelegraph, the EEZ framework would allow applications to leverage shared infrastructure across multiple rollups while ultimately settling finality on Ethereum. This approach could significantly reduce the duplication of effort and liquidity silos that have emerged as dozens of layer-2 (L2) networks have launched to scale the network.
Introducing the Ethereum Economic Zone
The core innovation of the EEZ is its model for “composable rollups.” In the current paradigm, a user or protocol wishing to move an asset or execute a sequence of actions across, for example, Arbitrum and Optimism must typically use a bridge—a process that introduces latency, security assumptions, and additional costs. The EEZ proposal instead envisions a system where a single transaction can atomically invoke contracts on multiple rollups. This would be achieved through a shared validation and sequencing layer that all participating rollups within the zone commit to, creating a unified execution environment.
“The goal is to make the experience of using a specific rollup irrelevant to the user and developer,” explained a contributor involved in the project, who requested anonymity. “Your assets and application logic can fluidly move between rollups in the EEZ, with Ethereum providing the ultimate security anchor.” The initiative is being developed in conjunction with Ethereum researchers and various industry participants, with early interest from infrastructure providers and DeFi protocols exploring a common standard for interoperability.
Technical specifications and performance benchmarks for the EEZ are slated for release in the coming weeks. The group is also establishing an “EEZ Alliance,” a consortium aimed at coordinating standards and driving adoption across the ecosystem as Ethereum’s multi-rollup future continues to take shape.
Ethereum’s rollup model sparks debate over fragmentation and scaling
The EEZ proposal arrives at a moment of intense introspection within the Ethereum community about the consequences of its “rollup-centric” scaling roadmap. While the proliferation of Optimistic and ZK-rollups like Arbitrum, Base, Optimism, and zkSync has dramatically increased transaction throughput and lowered fees, it has also led to a highly fragmented landscape.
According to data from L2BEAT, a trusted analytics platform, more than 20 active layer-2 networks are currently securing a combined total value locked (TVL) of nearly $40 billion. This capital, along with user activity and developer tools, is distributed across these parallel chains rather than consolidated. This fragmentation presents challenges for liquidity efficiency, user experience (requiring manual bridging), and the unified security narrative of Ethereum.
The Fragmentation Challenge
For decentralized finance (DeFi) protocols, fragmented liquidity can lead to reduced capital efficiency and slippage. For users, navigating multiple ecosystems involves complexity and the inherent risks of bridging. The EEZ framework directly targets this by proposing a standard that would allow a liquidity pool on one rollup to be seamlessly composable with a lending market on another, all within one transaction. This could unlock a new tier of hybrid applications that operate across rollups as if they were a single chain.
Vitalik Buterin’s Critique and Community Divide
Ethereum co-founder Vitalik Buterin has been a prominent voice in this debate, recently expressing concerns that some L2 designs deviate from core Ethereum values. In a February 3 post on X, he stated, “The original vision of L2s and their role in Ethereum no longer makes sense, and we need a new path.” He specifically highlighted issues like centralized sequencers and
