The Ethereum Layer 2 landscape is undergoing a painful but necessary correction. The recent closure of Zero Network highlighted the growing consensus among developers and investors that the days of one-size-fits-all rollups are numbered. In a market flooded with nearly identical scaling solutions, differentiation has become a matter of survival.
general problem
Ben Fisch, co-founder of Espresso Systems, a protocol focused on L2 interoperability, explained the issue clearly. The problem is not with Layer 2 technology itself, but with the overabundance of chains that offer the same thing. “There is no reason for there to be many networks with the same functionality,” Fish told CoinDesk. His argument is that without a clear value proposition, such as a specific use case, a bound user base, or a unique technical architecture, L2 has little reason to attract and retain liquidity.
Data confirms disparity
Data from DefiLlama reveals a grim picture. More than 80% of the total value locked in Ethereum L2 is concentrated in two networks: Base and Arbitrum. While these two giants continue to grow, others are hemorrhaging deposits. Linea, World Chain, Starknet, and Mantle have all seen declines in bridge deposits in recent months. This capital flight suggests that users and developers are voting with their wallets and integrating into the networks that offer the deepest liquidity, the best user experience, or the most attractive applications.
Why expertise matters
The emerging industry consensus is that only purpose-built L2s will survive. Coinbase’s Base is often cited as a prime example. It benefits from a large existing user base and a clear brand identity associated with Coinbase’s retail and institutional products. Other potential viable niches include L2 optimized for payments, stablecoin payments, or the tokenization of real-world assets (RWA). These specialized chains can offer lower fees, faster finality, or regulatory compliance features not easily achievable with general-purpose networks.
Ecosystem impact
This consolidation phase is healthy for the broader Ethereum ecosystem. A small number of high-quality, specialized L2s reduces fragmentation, improves security through a shared proof-of-concept infrastructure, and allows users to easily navigate the network. But it also means projects without clear differentiators or strong backers face an uphill battle. For investors and developers, the conclusion is clear. Building a general-purpose “Ethereum clone” is no longer a viable strategy.
conclusion
Layer 2 innovation is a natural maturation process for a technology that has experienced explosive growth. It shows that the market values quality and practicality over quantity. As the Zero Network closure shows, the window for undifferentiated L2 is closing. The future belongs to those who can answer one simple question. “What can I do that others can’t?”
FAQ
Q1: Why does generic layer 2 fail?
They lack differentiation. With numerous networks offering nearly identical functionality, users and liquidity naturally flow to the largest and most trusted networks like Base and Arbitrum, leaving smaller, more general-purpose L2s with little or no competitive advantage.
Q2: What kind of specialization is possible for L2 to survive?
Examples include L2 optimized for specific sectors such as payments, stablecoin issuance, tokenization of real-world assets, and gaming. Having your own user base, such as a large exchange or application, also provides a significant survival advantage.
Q3: Is this integration good for Ethereum?
Yes, in the long run. Fewer L2s and higher quality reduce network fragmentation, improve capital efficiency, and simplify the user experience. This is a sign that a mature ecosystem is moving towards sustainable growth.
