The Ethereum Layer 2 landscape is undergoing a painful but necessary correction. The recent closure of Zero Network has underscored a growing consensus among developers and investors: the era of generic, general-purpose rollups is coming to an end. In a market flooded with virtually identical scaling solutions, differentiation has become a matter of survival.
The general problem
Ben Fisch, co-founder of Espresso Systems, a protocol focused on L2 interoperability, has clearly stated the problem: the problem is not with the Layer 2 technology itself, but with the plethora of chains offering the same thing. “There is no reason for the existence of numerous networks with identical functions,” Fisch told CoinDesk. His argument is that without a clear value proposition – be it a specific use case, an established user base or a unique technical architecture – an L2 has little incentive to attract and retain liquidity.
Data confirms the gap
Data from DefiLlama paints a grim picture. More than 80% of all value captured in Ethereum L2s is now concentrated in just two networks: Base and Arbitrum. While these two giants continue to grow, other giants are bleeding. Linea, World Chain, Starknet and Mantle have all seen their bridging deposits decline in recent months. This capital flight suggests that users and developers are voting with their wallets and consolidating in the networks that offer the greatest liquidity, the best user experience, or the most attractive applications.
Why specialization is important
The consensus within the emerging industry is that only L2s built for a specific purpose will survive. Coinbase’s Base is often cited as the best example. It benefits from a huge, existing user base and a clear brand identity tied to Coinbase’s retail and institutional products. Other potential survival niches include L2s optimized for payments, stablecoin settlements, or real-world asset (RWA) tokenization. These specialized chains can offer lower costs, faster finality, or regulatory compliance features that general-purpose networks cannot easily match.
Implications for the ecosystem
This consolidation phase is healthy for the broader Ethereum ecosystem. A smaller number of high-performance, specialized L2s reduces fragmentation, improves security through shared test infrastructure, and makes it easier for users to navigate the network. However, it also means that projects without a clear distinctive character or strong support face an uphill battle. For investors and developers, the message is clear: building a generic ‘Ethereum clone’ is no longer a viable strategy.
Conclusion
The Layer 2 shakeout is a natural maturation process for a technology that has experienced explosive growth. The market indicates that it considers quality and usefulness more important than quantity. As the closure of Zero Network shows, the window for undifferentiated L2s is closing. The future belongs to those who can answer one simple question: What can you do that no one else can?
Frequently asked questions
Question 1: Why do general-purpose Layer 2s fail?
They lack differentiation. With dozens of networks offering nearly identical functionality, users and liquidity naturally flow to the largest and most trusted networks like Base and Arbitrum, leaving smaller, generic L2s with little to no competitive advantage.
Question 2: What kind of specialization can help an L2 survive?
Examples include L2s optimized for specific industries such as payments, stablecoin issuance, real-world asset tokenization, or gaming. Having an established user base, such as a major exchange or application, also provides a significant survival advantage.
Question 3: Is this consolidation good for Ethereum?
Yes, in the long run. Fewer, higher-quality L2s reduce network fragmentation, improve capital efficiency, and simplify the user experience. It is a sign of a maturing ecosystem that is moving towards sustainable growth.
