When Zero Community introduced it was shutting down final month, the response throughout crypto was weary: One other Ethereum layer-2 simply bit the mud.
The closure joined a rising checklist of struggling rollups and got here amid renewed debate about whether or not Ethereum’s sprawling layer-2 ecosystem has turn into too crowded. On the identical time, Ethereum creator Vitalik Buterin has urged builders to rethink the community’s long-term scaling roadmap, whereas a number of main tasks have shifted away from advertising and marketing themselves as general-purpose blockchains and towards extra targeted functions in funds, stablecoins and tokenized belongings.
To many observers, the developments have revived a well-recognized query: Has Ethereum’s sprawling layer-2 ecosystem turn into too crowded?
Trade members, nonetheless, argue the alternative.
“The factor to acknowledge is that anyplace the place any person 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 section for general-purpose layer twos, not layer twos broadly.”
Ethereum layer-2s exploded over the previous a number of years as enhancements in rollup know-how dramatically diminished the associated fee and complexity of launching new chains. Rollups work by processing transactions off Ethereum’s foremost blockchain, bundling tons of 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 final 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 turned simpler, attracting customers proved a lot tougher.
“There have been approach too many general-purpose layer twos, which frankly do not make sense as a product, as a result of there is no cause to have many, many variations of the identical factor,” Fisch mentioned.
The numbers help that view. At present, 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 accordance with DefiLlama knowledge.
That focus has solely turn into extra obvious as smaller chains wrestle to keep up 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 feel 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 know-how 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 cause to proceed sustaining an L2,” she mentioned.
Paradoxically, the economics of launching a rollup have by no means appeared higher. Ethereum’s Dencun improve, launched in 2024, dramatically diminished the price of posting rollup knowledge to Ethereum via blobs. In line with 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 positively cheaper to run an L2 at this time,” Hou mentioned. “The economics of launching an L2 have turn into simpler, however the actual problem continues to be producing sufficient sustained demand to make the community value 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 totally different general-purpose blockchains compete with one another,” Fisch mentioned. “If you wish to succeed, it is advisable construct out a differentiated software.”
From infrastructure to functions
The shift is already seen throughout the trade. A number of blockchain tasks that after emphasised infrastructure are more and more specializing in funds, stablecoins, tokenized belongings and different application-specific markets. Conventional monetary establishments could turn into a few of the greatest beneficiaries.
Fisch pointed to asset managers launching tokenized money-market funds, stablecoin 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 provide decrease prices, better management and extra predictable efficiency than deploying immediately as a wise contract.
“The know-how resolution to run as a layer two is solely an choice of operating an software onchain,” Fisch mentioned.
Hou mentioned she agreed that distribution issues greater than know-how.
“Solely L2s with a strong current consumer base and a transparent cause 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 turn into the dominant instance, leveraging the change’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 special 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 answer for Ethereum itself.
Fisch mentioned he sees them otherwise.
“I do not view layer twos as scaling Ethereum,” he mentioned. “I view layer twos as leveraging the prevailing safety properties of layer one.”
In that framework, Ethereum features much less as a vacation spot and extra as a settlement layer that functions can use when it is sensible.
“Ethereum is kind 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. Quite than competing to turn into the subsequent dominant blockchain, extra tasks are more and more treating blockchains as modular parts that may be assembled into bigger merchandise.
If that development continues, the longer term Ethereum ecosystem could look very totally different from the one imagined throughout the rollup growth. As a substitute of tons of of competing general-purpose chains preventing for liquidity, the winners might be a smaller variety of networks tied to particular companies, monetary merchandise and consumer communities.
