The DeFi yield aggregation protocol ACryptoS announced that due to an attack on the treasury, the deposit function has been disabled, while the withdrawal function remains open. ACryptoS analysis indicates that due to a lack of input validation, attackers only need to deposit a minimal amount of tokens to mint a majority of the shares in the treasury.This attack affected 77 treasuries across 5 chains, resulting in a total loss of approximately $665,000. Currently, the stolen funds have been transferred through multiple cross-chain protocols, and the attackers have been offered a condition to return the funds while keeping a 10% bounty. Additionally, ACryptoS stated that due to the inability to continue maintenance, the project has ceased operations and is urging users to withdraw their assets as soon as possible.

The prediction market revenue protocol Robin Markets announced the shutdown of V1. The team stated that the initial version of the revenue product did not achieve the expected adoption and will be gradually phased out to allow for the re-launch of an improved version. The points program, revenue guarantees, and matching rewards will cease along with V1; these mechanisms were originally intended to incentivize liquidity but did not perform as expected. Existing products will continue to operate until the new version is launched by the end of this year.The team outlined two main issues. The first is position matching: V1 needs to match opposing YES and NO positions within each market's liquidity pool to combine funds into USDC for use, and the efficiency of funds depends on whether the distribution on both sides is relatively balanced. This creates a first-mover disadvantage, as tokens deposited early often remain idle before a counterparty appears, resulting in thin liquidity pools, and early users frequently cannot earn returns. The second issue is changes in the revenue environment: at the project's launch, the yield on USDC.e on Polygon was still considerable, and there was a partnership with Yearn; after October 10, more yield channels on Polygon shrank or lost competitiveness, weakening the original sources of revenue and placing greater pressure on subsidy guarantees. The team stated that insufficient matching and weakening revenue mutually influence each other, hindering the product's actual operation.Robin Markets positions itself as the capital efficiency layer of the prediction market, allowing users to stake Polymarket outcome tokens on Polygon while earning returns without losing their original market exposure. Public information shows that the project previously completed a $475,000 angel round of financing, with investors including Fabric VC, Animoca Brands, ATKA Incubator, John Lilic, Stefan D. George, and angel investors from Hilbert Capital, LayerZero, and others. The team stated that the next version will directly address the issues of matching mechanisms and revenue sources.

The decentralized liquidity staking protocol Diva Staking announced on social media that it will shut down the project and will not launch the mainnet. The official statement said that this decision was made after thorough discussion and apologized to the early stakers who had pre-deposited in the vault, stating that related deposits can be withdrawn through Enzyme without further waiting.The official statement mentioned that the team has been operating for about two and a half years without income or salary since the funds were exhausted in mid-2024, with three members pushing the project forward. Diva went live on the Hoodi testnet earlier this summer and has been running stably for about four months without any issues, but failed to gain support from large institutions for the mainnet launch. The three-member team also could not bear the costs of a new round of audits and mainnet operations, thus choosing to wind down rather than risk launching.The announcement also stated that the demand structure for LST has changed after the Shanghai upgrade. As of the end of June this year, BitMine, Coinbase, and Binance together accounted for about 30% of the total staked ETH, with approximately 11.5%, 10.9%, and 7.9% respectively, which is comparable to the concentration when the market was concerned about Lido's share being close to one-third. The official also congratulated Lido for advancing Simple DVT and opening up to independent stakers.

The Browser Company announced that it will completely cease the operation of the macOS and Windows versions of the Arc browser on December 22, 2026, and has closed new user registrations. Starting from November 23, the AI features on mobile, login, and tab synchronization will gradually be disabled, and the team will fully shift its focus to the AI browser Dia.Arc was launched in 2022, initially limited to Mac users through invitations, and was fully opened in 2023, with plans to gradually launch on Windows and mobile platforms in 2024. The product design includes a vertical tab bar, independent workspaces, automatic tab organization, split-screen browsing, and allows users to directly modify the appearance of web pages. The official disclosure indicated that Arc had over 1 million weekly active users.Founder Josh Miller stated in 2025 that Arc was too complex for ordinary users, with a high learning cost, and only 5.52% of daily active users frequently used multiple workspaces. The team stopped developing new features that year and shifted to Dia. In October of the same year, the parent company was acquired by Atlassian for approximately $610 million. The reason for the shutdown was that browser security in the AI era requires continuous investment, and engineering and security resources must be concentrated on Dia.

Regarding the announcement "Polygon is not dead" released by Polygon's official Twitter, which is suspected to mock the shutdown of Abstract, Polygon founder Sandeep responded that the dissemination effect of the related content "did not meet expectations," and some people attributed a completely different meaning to it. The Polygon marketing team was self-deprecating, as Polygon's fundamentals are still growing, and there was no intention to imply anything about Abstract's shutdown.Sandeep added that he was also confused when he first saw the content and emphasized that he has great respect for Abstract founder Luca Netz and his team. Since Polygon itself had also terminated the zkEVM project, he empathizes with the pain and would not mock the other party, wishing Luca and the Pudgy Penguins team all the best.

According to on-chain information, shortly after the shutdown announcement of Abstract, a newly created address withdrew 1 million USD from Kraken and then quickly bought 25 Pudgy Penguins NFTs on the market.

NFT and IP company Igloo, Inc. announced the shutdown of its consumer-grade blockchain Abstract, reallocating personnel and resources to Pudgy Penguins, Pudgy NFT, and the token PENGU.Igloo stated that the goal of Abstract was to create a public chain for consumer scenarios, and the company invested engineering and ecological talent and infrastructure for this purpose. Its growth was constrained by the high operational costs of independent blockchain, limited liquidity, a weak DeFi ecosystem, and declining market interest. Over the past two years, Igloo has lost tens of millions of dollars to maintain Abstract's operations, expand, and seek product-market fit and profitability.The company stated that after even well-funded enterprises struggled to find product-market fit for their own blockchain, shutting down Abstract became the right decision. Moving forward, they will refine the brand path from products and content to PENGU, and then to Pudgy Penguins NFT, refocusing on this role as an IP.

The team stated that over the past two years, Web3 liquidity has remained scarce, the market focus has shifted to AI, the enthusiasm for cross-chain interoperability has waned, and the revenue from bridging services has been insufficient to cover costs.

Router Protocol will permanently destroy 303,333,198 ROUTE tokens pending in the treasury and will coordinate with centralized exchanges to delist ROUTE. Holders need to withdraw their tokens according to the arrangements of each exchange before the deadline. In addition, the project will not launch any new plans related to ROUTE and plans to open-source some technical components for community use.
