Igloo Inc., the parent company of Pudgy Penguins, said on Oct. 6 that its Ethereum layer-2 network Abstract will be wound down in phases, with the mainnet set to shut on Dec. 15. After that date, any assets still left on the chain will no longer be accessible.
The announcement came less than a week after Blast said it would shut down as well. The report draws a clear distinction between the two cases. Blast, it said, collapsed after activity and revenue dried up, with total value locked falling 98% from $2.27 billion and daily revenue at $110 on the day before the shutdown. Abstract, by contrast, had users, applications and brand partnerships, yet still could not support itself.
Users and partnerships were not enough
The report said Abstract had more than 400,000 users, 4 million wallets, 144 applications, 325 million transactions, and partnerships with brands including Red Bull Racing and Disney. Those are the kinds of metrics many L2 projects would want to show. They still did not produce a viable business.
Igloo CEO Luca Netz wrote on X that the company had been funding Abstract for 18 months and had lost "tens of millions" of dollars in the process. In July 2024, Igloo raised more than $11 million in a funding round led by Founders Fund, with the stated goal of using Pudgy Penguins' brand distribution to bring consumers on-chain. Abstract mainnet went live in January 2025.
What followed, according to the report, was a failure to build a DeFi ecosystem. Liquidity on the chain remained thin. Institutional participation stayed very limited. The operating budget was also much smaller than that of competing networks.
Netz said Igloo could have issued an Abstract token and even run an ICO to keep the project alive longer, but decided against it. He wrote, "A token needs real demand to drive its value. Launching a token that we ourselves do not have confidence in would be a disservice to the community."
The gap between 4 million wallets and 400,000 users
On paper, Abstract's metrics did not look weak. The report said more than 4 million Abstract Global Wallets had been created, more than 400,000 users had used the network, more than 325 million transactions had been processed, and 144 applications had been deployed.
CryptoBriefing highlighted what it called a revealing gap: "The disparity between 4 million wallets and roughly 400,000 users is itself telling."
Using those figures, the report said the average real user had created about 10 wallets. Many of those wallets may have been empty, inactive, or created in batches in anticipation of a possible airdrop. In traditional internet terms, that is the difference between registered users and active users. In crypto, where wallet creation is effectively free, that gap can widen much more quickly.
The more important question is how many of those users were generating fee-paying on-chain activity. Abstract was positioned as a consumer-friendly chain, which meant its user base leaned more toward NFT collectors, brand campaign participants and casual users than high-frequency DeFi traders.
That brings the discussion back to the same structural issue seen in the Blast case. A chain earns revenue from transaction fees, not from user counts alone. A network can have a million users, but if they only make one transaction a month, the gas generated may still fall short of covering sequencer and operating costs.
Two L2 shutdowns in one week
The report said Blast and Abstract shutting down in the same week was not a coincidence. Together with Botanix, a Bitcoin layer-2 project that shut down in June, three venture-backed L2 networks have now come to an end in 2026.
That points to a harsher market test now playing out across the Ethereum L2 sector: many L2s may not be able to survive as standalone businesses.
There are currently dozens of L2s operating on Ethereum. The report said most of them are highly similar at the technical level, using the same rollup architecture, supporting the same EVM compatibility, and bridging back to the same Ethereum mainnet. That leaves little room for durable differentiation.
In the article's framing, the chains that have managed to survive tend to fit one of two models. One relies on distribution. Base benefits from Coinbase's tens of millions of users, which keeps customer acquisition costs low. The other relies on early ecosystem formation. Arbitrum had already accumulated a large number of DeFi protocols in 2022, and user capital and habits had already settled on the chain.
Abstract had neither, the report argued. It had a brand, and Pudgy Penguins is well known in the NFT market, but brand awareness is not the same as on-chain transaction behavior. A consumer who bought a Pudgy Penguins toy is not the same as a DeFi user willing to borrow and lend on-chain.
What the shutdown means for PENGU
After announcing the shutdown, Igloo said it would refocus all resources on Pudgy Penguins and the PENGU token. PENGU fell about 5.6% on the day of the announcement to around $0.009.
The report laid out two sharply different readings of what Abstract's closure means for PENGU.
One is a loss-cutting argument. Under that view, Abstract had been consuming millions of dollars in operating resources each month, money that could have gone into Pudgy Penguins brand expansion and PENGU ecosystem development. Closing an L2 that could not generate positive cash flow and redirecting capital and staff toward businesses with real revenue models would be a rational allocation decision.
The other is a contraction argument. The report said Abstract had been the core vehicle for Igloo's broader growth story, moving from an NFT brand into on-chain infrastructure. Without its own chain, PENGU becomes a community token living on someone else's network again, losing the valuation narrative attached to owning a chain. Over the longer term, that could lower Igloo's strategic ceiling.
Which reading proves correct, the article said, will depend on what happens over the next few months: whether Igloo puts the resources saved from Abstract into real utility for PENGU, whether Pudgy Penguins' brand licensing revenue can cover company operations, and whether PENGU holders receive any form of revenue sharing or buyback mechanism.
For now, those questions remain unanswered. The shutdown notice stops the bleeding, but it does not explain what growth engine comes next.
Users have until Dec. 15 to move funds
For users still holding assets on Abstract, the immediate issue is migration.
According to Unchained, there is still about $47 million in assets on the chain. Users can move funds to Ethereum mainnet through the Migration Hub or the Abstract native bridge. The native bridge currently has a delay of about three hours.
After Dec. 15, once the chain is shut down, any funds that have not been migrated will become inaccessible. Abstract also warned users to watch for phishing sites impersonating migration portals and to use only official channels.
In his farewell statement, Netz wrote, "Some people will be happy with this outcome. That reaction is fair. Building a chain is extremely hard to succeed at, and I am proud that we tried. My only regret is that we did not get to celebrate a win with the Abstract community."
The report's closing argument is that Blast showed that money without users does not work, while Abstract showed that users without a sustainable revenue base do not work either. The next question, it said, is whether the countdown has already started for L2s that have both capital and users but still depend on subsidies to keep their ecosystems running.
