When Zero Community announced it was shutting down last monththe response throughout crypto was weary: One other Ethereum layer-2 simply bit the mud.
The closure joined a rising listing of struggling rollups and got here amid renewed debate about whether or not Ethereum’s sprawling layer-2 ecosystem has grow to be too crowded. On the identical time, Ethereum creator Vitalik Buterin has urged developers to rethink the network’s long-term scaling roadmap, whereas a number of main initiatives have shifted away from marketing themselves as general-purpose blockchains and towards more focused applications in payments, stablecoins and tokenized belongings.
To many observers, the developments have revived a well-known query: Has Ethereum’s sprawling layer-2 ecosystem grow to be too crowded?
Business contributors, nonetheless, argue the other.
“The factor to acknowledge is that anyplace the place someone could be operating a wise contract on an current blockchain, somebody may equally run a layer two,” mentioned Ben Fisch, co-founder and CEO of Espresso Methods. “We’re in a consolidation part for general-purpose layer twos, not layer twos broadly.”
Ethereum layer-2s exploded over the previous a number of years as enhancements in rollup expertise dramatically diminished the associated fee and complexity of launching new chains. Rollups work by processing transactions off Ethereum’s predominant blockchain, bundling a whole lot of them collectively, after which periodically posting compressed transaction knowledge again to Ethereum for settlement and safety. The mannequin permits functions to supply quicker transactions and decrease charges whereas nonetheless counting on Ethereum as the last word supply of belief.
The outcome was a flood of networks constructed utilizing infrastructure stacks resembling Optimism’s OP Stack, Arbitrum Orbit and zkSync. However whereas launching a sequence grew to become simpler, attracting customers proved a lot more durable.
“There have been method too many general-purpose layer twos, which frankly do not make sense as a product, as a result of there is not any purpose to have many, many variations of the identical factor,” Fisch mentioned.
The numbers assist that view. In the present day, exercise throughout Ethereum’s layer-2 ecosystem stays closely concentrated amongst a handful of networks. Base and Arbitrum alone account for greater than 80% of layer-2 DeFi whole worth locked (TVL), in response to DefiLlama knowledge.
That focus has solely grow to be extra obvious as smaller chains battle to take care of liquidity. Over the previous six months, networks together with Linea, World Chain, Starknet and Mantle have all seen declining bridge deposits. Linea’s deposits, for instance, fell from $976 million in November 2025 to $367 million in Could 2026, a decline of greater than 60%.
“I believe just a few L2s with clear monetary demand will be capable to maintain themselves over time,” mentioned Alice Hou, a former analysis analyst at Messari, to CoinDesk.
For Hou, the important thing challenge is not whether or not layer-2 expertise works, it is whether or not a community can generate sufficient exercise to justify its existence.
“With out sufficient blockspace demand, consumer exercise or developer traction, there’s little purpose to proceed sustaining an L2,” she mentioned.
Satirically, the economics of launching a rollup have by no means appeared higher. Ethereum’s Dencun improve, launched in 2024, dramatically reduced the cost of posting rollup data to Ethereum via blobs. In response to Messari analysis, knowledge availability prices now characterize solely a small fraction of operator bills for a lot of OP Stack chains.
“From an operator perspective, it’s undoubtedly cheaper to run an L2 right this moment,” Hou mentioned. “The economics of launching an L2 have grow to be simpler, however the true problem remains to be producing sufficient sustained demand to make the community price working.”
That dynamic has created a paradox. The obstacles to making a blockchain proceed to fall, however the obstacles to attracting customers proceed to rise. In consequence, many groups are discovering that merely providing one other Ethereum-compatible chain is not sufficient.
“Folks have realized that every one the completely different general-purpose blockchains compete with one another,” Fisch mentioned. “If you wish to succeed, you must construct out a differentiated utility.”
From infrastructure to functions
The shift is already seen throughout the trade. A number of blockchain initiatives that after emphasised infrastructure are more and more specializing in funds, stablecoins, tokenized belongings and different application-specific markets. Conventional monetary establishments might grow to be a few of the greatest beneficiaries.
Fisch pointed to asset managers launching tokenized money-market fundsstablecoin issuers and tokenized deposit platforms as examples of companies which have clear causes to function on-chain. For these companies, a devoted layer-2 can supply decrease prices, better management and extra predictable efficiency than deploying instantly as a wise contract.
“The expertise determination to run as a layer two is just an possibility of operating an utility onchain,” Fisch mentioned.
Hou mentioned she agreed that distribution issues greater than expertise.
“Solely L2s with a strong current consumer base and a transparent purpose to learn from blockchain infrastructure ought to launch their very own networks,” she mentioned.
That helps clarify why exchanges stay among the many strongest candidates. Coinbase’s Base has grow to be the dominant instance, leveraging the trade’s current buyer base whereas integrating customers into Ethereum’s broader DeFi ecosystem.
“The query shouldn’t be, ‘Can this firm launch an L2?'” Hou mentioned. “It must be: ‘Does this enterprise have already got sufficient distribution, monetary exercise and ecosystem synergies to make an L2 meaningfully helpful?'”
A distinct imaginative and prescient for the layer-2 panorama
The talk additionally displays a deeper disagreement about what layer-2s are literally for. For years, Ethereum advocates framed rollups primarily as a scaling solution for Ethereum itself.
Fisch mentioned he sees them in another way.
“I do not view layer twos as scaling Ethereum,” he mentioned. “I view layer twos as leveraging the present safety properties of layer one.”
In that framework, Ethereum capabilities much less as a vacation spot and extra as a settlement layer that functions can use when it is smart.
“Ethereum is form of a commodity that layer twos can select to make use of,” Fisch mentioned.
That imaginative and prescient aligns with a broader development unfolding throughout crypto infrastructure. Relatively than competing to grow to be the subsequent dominant blockchain, extra initiatives are more and more treating blockchains as modular elements that may be assembled into bigger merchandise.
If that development continues, the longer term Ethereum ecosystem might look very completely different from the one imagined in the course of the rollup growth. Instead of hundreds of competing general-purpose chains fighting for liquiditythe winners might be a smaller variety of networks tied to particular companies, monetary merchandise and consumer communities.
