Not all Ethereum L2s are dying, but many general-purpose chains no longer have a reason to exist (12 words exactly...

Let me try: "Not all Ethereum L2s are dying, but many chains no longer have a reason" - 14 words "Many general-purpose Ethereum L2s no longer have a reason to exist" - 11 words "Not all Ethereum L2s are dying—just most of the general-purpose ones" - 12 words

The original is good but maybe too long. Let me check 12 words: "Many general-purpose Ethereum L2s no longer have a reason to exist" - that's 11 words. Good.

Or keep close to original: "Not All Ethereum L2s Are Dying, But Many Chains Should Be" - 11 words but uses "Should" which isn't quite right.

Let me go with something close to original but tighter: "Many general-purpose Ethereum L2s no longer have a reason to exist" - 11 words.

Actually the original is 14 words. Let me try: "Not all Ethereum L2s are dying—just the general-purpose ones" - 11 words.

I'll go with: "Not all Ethereum L2s are dying, but many general-purpose chains have no reason to exist" - 15 words. Too long.

Let me just use: "Many general-purpose Ethereum L2s no longer have a reason to exist" - 11 words. Clean.

Now for the polishing, I want to:

1. Keep all facts, numbers, quotes exact
2. Add light dry humor where natural
3. Fix any awkward phrasing
4. Maintain paragraph count

Let me check the first paragraph again: "When Zero Network announced it was shutting down last month, the reaction across crypto was weary: Another Ethereum layer-2 just bit the dust."

"Weary" is interesting word choice. It should be something like "weary" but that's used as an adjective... I think it should be "weary" meaning tired/resigned. The original has "weary" which seems correct in context.

Wait, looking at it again: "the reaction across crypto was weary" - this works. People are tired of L2s dying.

"Another Ethereum layer-2 just bit the dust" - dust is from old westerns, could be slightly humorous.

Now the cut-off ending: "People have realized that all the different general-purpose blockchains compete with e" - this is cut off. I should leave it as is since I can't add content.

Let me also check facts:

• Zero Network shutting down last month
• Vitalik Buterin urged developers to rethink scaling roadmap
• Base and Arbitrum account for more than 80% of L2 DeFi TVL
• DefiLlama data
• Linea deposits fell from $976M (Nov 2025) to $367M (May 2026), 60% decline
• Dencun upgrade in 2024
• Messari research
• Quote from Ben Fisch, Espresso Systems
• Quote from Alice Hou, former Messari research analyst

Networks mentioned: Linea, World Chain, Starknet, Mantle (declining bridge deposits) Infrastructure stacks: OP Stack, Arbitrum Orbit, zkSync

Now let me write the polished version:

Para 1: "When Zero Network announced it was shutting down last month, the reaction across crypto was weary: another Ethereum layer-2 just bit the dust. The closure joined a growing list of struggling rollups and arrived amid renewed debate over whether Ethereum's sprawling layer-2 ecosystem has become too crowded. Meanwhile, Vitalik Buterin has urged developers to rethink the network's long-term scaling roadmap, and several major projects have shifted away from pitching themselves as general-purpose blockchains, pivoting instead toward payments, stablecoins and tokenized assets."

(Changed "was weary" to was a bit more natural, used "arrived" instead of "came", "over" instead of "about whether", "Meanwhile" instead of "At the same time", "pitching" instead of "marketing", "pivoting instead" for flow. Lowercase "another" since it's mid-sentence.)

Para 2: "To many observers, the developments have revived a familiar question: has Ethereum's sprawling layer-2 ecosystem become too crowded?"

(This is the redundant question. I could maybe change it to: "To many observers, the developments have revived a familiar question: has the layer-2 ecosystem finally hit its limit?" - no, I should keep it close to original. Maybe: "To many observers, these developments have revived a familiar question: has Ethereum's layer-2 ecosystem become too crowded?" - slightly tighter.)

Para 3: "Industry participants, however, argue the opposite. 'The thing to recognize is that anywhere where somebody would be running a smart contract on an existing blockchain, someone could equally run a layer two,' said Ben Fisch, co-founder and CEO of Espresso Systems. 'We're in a consolidation phase for general-purpose layer twos, not layer twos broadly.'"

(Quote preserved exactly.)

Para 4: "Ethereum layer-2s exploded over the past several years as improvements in rollup technology dramatically reduced the cost and complexity of launching new chains. Rollups work by processing transactions off Ethereum's main blockchain, bundling hundreds of them together, and then periodically posting compressed transaction data back to Ethereum for settlement and security. The model allows applications to offer faster transactions and lower fees while still relying on Ethereum as the ultimate source of trust."

Para 5: "The result was a flood of networks built using infrastructure stacks such as Optimism's OP Stack, Arbitrum Orbit and zkSync. But while launching a chain became easier, attracting users proved much harder. 'There were way too many general-purpose layer twos, which frankly don't make sense as a product, because there's no reason to have many, many versions of the same thing,' Fisch said."

Para 6: "The numbers support that view. Today, activity across Ethereum's layer-2 ecosystem remains heavily concentrated among a handful of networks. Base and Arbitrum alone account for more than 80% of layer-2 DeFi total value locked (TVL), according to DefiLlama data. That concentration has only become more apparent as smaller chains struggle to maintain liquidity."

Para 7: "Over the past six months, networks including Linea, World Chain, Starknet and Mantle have all seen declining bridge deposits. Linea's deposits, for example, fell from $976 million in November 2025 to $367 million in May 2026, a decline of more than 60%. 'I think only a few L2s with clear financial demand will be able to sustain themselves over time,' said Alice Hou, a former research analyst at Messari, to CoinDesk."

Para 8: "For Hou, the key issue isn't whether layer-2 technology works—it's whether a network can generate enough activity to justify its existence. 'Without enough blockspace demand, user activity or developer traction, there is little reason to continue maintaining an L2,' she said."

Para 9: "Ironically, the economics of launching a rollup have never looked better. Ethereum's Dencun upgrade, introduced in 2024, dramatically reduced the cost of posting rollup data to Ethereum through blobs. According to Messari research, data availability costs now represent only a small fraction of operator expenses for many OP Stack chains."

Para 10: "'From an operator perspective, it is definitely cheaper to run an L2 today,' Hou said. 'The economics of launching an L2 have become easier, but the real challenge is still generating enough sustained demand to make the network worth operating.'"

Para 11: "That dynamic has created a paradox. The barriers to creating a blockchain continue to fall, but the barriers to attracting users continue to rise. As a result, many teams are discovering that simply offering another Ethereum-compatible chain is no longer enough. 'People have realized that all the different general-purpose blockchains compete with e"

(I need to preserve the cutoff)

Wait, the original has slightly different paragraph breaks. Let me recount:

Original: P1: "When Zero Network announced..." through "...tokenized assets." P2: "To many observers, the developments have revived a familiar question: Has Ethereum's sprawling layer-2 ecosystem become too crowded? Industry participants, however, argue the opposite. "The thing to recognize..." through "We're in a consolidation phase for general-purpose layer twos, not layer twos broadly."" P3: "Ethereum layer-2s exploded over the past several years..." through "...ultimate source of trust." P4: "The result was a flood of networks built using infrastructure stacks such as Optimism's OP Stack, Arbitrum Orbit and zkSync. But while launching a chain became easier, attracting users proved much harder. "There were way too many..." P5: "The numbers support that view. Today, activity across Ethereum's layer-2 ecosystem remains heavily concentrated among a handful of networks. Base and Arbitrum alone account for more than 80% of layer-2 DeFi total value locked (TVL), according to DefiLlama data. That concentration has only become more apparent as smaller chains struggle to maintain liquidity. Over the past six months, networks including Linea, World Chain, Starknet and Mantle have all seen declining bridge deposits. Linea's deposits, for example, fell from $976 million in November 2025 to $367 million in May 2026, a decline of more than 60%.

For Hou, the key issue isn't whether layer-2 technology works, it's whether a network can generate enough activity to justify its existence. "Without enough blockspace demand, user activity or developer traction, there is little reason to continue maintaining an L2," she said." P6: "Ironically, the economics of launching a rollup have never looked better.

P7: "That dynamic has created a paradox. The barriers to creating a blockchain continue to fall, but the barriers to attracting users continue to rise.

"People have realized that all the different general-purpose blockchains compete with e"

So there are 7 paragraphs. Let me make sure I preserve that count.

Actually, looking at the source more carefully, I see there are some line breaks but they might just be visual. Let me count again by looking for paragraph breaks (double newlines):

"When Zero Network announced it was shutting down last month, the reaction across crypto was weary: Another Ethereum layer-2 just bit the dust.
