Every cycle, crypto convinces itself the world needs another chain. A new network arrives with faster blocks, a slick logo and a deck promising to fix everything its predecessors got wrong. Incentives flow in, TVL charts go vertical, and everyone calls it adoption.
October 2026 showed what happens when the money stops.
The shutdown notices
Blast went first. The Paradigm-backed Ethereum layer-2 said on October 2 that its operating costs exceeded its revenue and that it saw no credible path to sustainability. DefiLlama showed just over $32 million locked, down from more than $2 billion before its early-2024 mainnet launch. Users have until October 26 to withdraw through the normal interface, after which they must use Blast’s bridge contracts on Ethereum directly.
Days later came Abstract. The chain, backed by Pudgy Penguins’ parent company Igloo, will close on December 15. Igloo’s CEO said the company funded it for 18 months and lost tens of millions of dollars, with about $48 million in assets still on the chain at the time. The telling detail is that Abstract processed more than 300 million transactions and still failed to find product-market fit. Activity is not a business.
Lisk is the one L1 holders should study. It launched in 2016 as a layer-1 and moved to an Ethereum layer-2 in late 2023 and early 2024, citing chain economics and sustainability. Its chain will now shut down on October 31 as the company pivots to a finance-operations platform. The LSK token itself isn’t being discontinued. The chain, however, wasn’t enough.
A year earlier, Kadena offered a preview. The company behind the proof-of-work L1 announced in October 2025 that it was ending all business activity and active maintenance. The network keeps running on independent miners. The KDA token sat about 99.7% below its 2021 peak. A chain that runs but has no team and no momentum isn’t thriving. It’s a zombie.
Why small chains are getting squeezed
Cheap blockspace is a gift to users and a problem for small operators. Cheaper Ethereum data made transactions cheaper but narrowed the margin that smaller chains need to cover sequencer, bridge and security costs. At the same time, users flow to depth. 21Shares found that by late 2025, Base, Arbitrum and Optimism already processed nearly 90% of L2 transactions. L2BEAT’s early-October snapshot showed about $43.56 billion secured across tracked projects, with Base near $16.24 billion and Arbitrum One near $11.42 billion. By my math, those two alone hold well over half.
The L1 objection
Here’s the honest caveat. Most of the closures so far are layer-2s, and L1 defenders will say that proves nothing. They have a point. An L1 earns fees and issues tokens to pay validators, so it can limp along far longer than a rollup that must fund its own infrastructure.
But limping isn’t living. Lisk shows an L1 that couldn’t make its economics work and then couldn’t make the rebuild work either. Kadena shows how a chain can outlive its company and still be worthless. The question for any L1 isn’t whether it will stay online. It’s whether anyone pays for it to matter.

What survives
Three things protect a chain: a niche nobody else serves, liquidity that’s costly to move, or built-in distribution. Base has Coinbase. Arbitrum has deep DeFi. Most others have a roadmap and a token.
What to do about it
If you hold a layer-1 token, ask where organic usage comes from, who pays fees once incentives end, and what the chain does that nothing else can. If the answers are vague, treat the token like a bet on a business that hasn’t shown it can cover its costs.
The shutdown notices have started. The next ones won’t come with a warning.
