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discussion and apologized to the early stakers who had pre-deposited in the vault, stating that related deposits can be withdrawn through Enzyme without further waiting.The official statement mentioned that the team has been operating for about two and a half years without income or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.

According to the announcement from Forma's official X account, the Forma mainnet will stop operating at block height 34,567,890, expected around November 5th, giving users about two weeks to withdraw on-chain funds.After the chain stops, the team will take a snapshot of the on-chain state and migrate the remaining TIA to Eden. Both chains are EVM chains, and users can use the same wallet address to withdraw funds from Eden after the migration is complete.Modularium will migrate to Ethereum, and the related NFTs will be migrated as well; holders will need to claim them themselves through the re-launched Modularium website, as NFTs will not be automatically airdropped. The official statement indicates that the migration may take several days after the chain stops, and further announcements will be made when the migration is complete, along with more details and operational instructions in the coming weeks.

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.

The messaging protocol XMTP founder Shane Mac stated that XMTP will evolve into a self-operating open-source messaging stack, providing private conversations between people and agents, with infrastructure controlled by users, without requiring tokens or wallets. The network hosted by XMTP Labs will shut down in early 2027.Shane Mac mentioned that he founded XMTP five years ago because he believed that private messaging should not be owned by a single company. He recalled that the team envisioned using wallets as cross-application identities, allowing messages to follow identities, and using tokens to pay infrastructure operators, but this path was not realized. XMTP has never issued tokens and will not issue them now. He admitted that it was a wrong decision to persist with a single shared network for a long time, as developers have consistently requested the ability to self-host XMTP. Therefore, it has shifted to self-hosting, allowing developers to use, inspect, modify, and maintain the entire software suite without relying on Labs. Former employees will assist in maintaining the protocol, and Shane Mac himself will continue to be involved.The article introduces that self-hosted XMTP offers quantum-resistant end-to-end encryption, private one-on-one and group chats, encrypted identities, and message authenticity, as well as SDKs for mobile, web, server, and agents. Chief Technology Officer Nick Molnar has simplified the backend to a single Rust binary and integrated attachments, push notifications, handles, and signed webhooks for new messages. Each self-hosted network does not automatically interconnect by default, and agents from different tools must connect to the same backend to share conversations.

The entertainment application chain Sophon officially announced that the team plans to finally shut down the Sophon mainnet on November 30, 2026. Key infrastructure and related websites will begin to shut down after November 25. Assets remaining on the Sophon Chain after the deadline face the risk of permanent inaccessibility.

The Bitcoin infrastructure protocol Echo Protocol announced on platform X that it will gradually terminate the operation of the protocol due to business adjustments. The official announcement expressed gratitude to the community, partners, and users for their long-term trust and support, and committed to completing the subsequent liquidation work transparently and responsibly.Currently, all core businesses of the Echo Protocol have fully stopped accepting incremental funds. The lending protocol has halted new deposits, new loans, and interest accrual, while the strategy and LSD businesses have also ceased new deposits and new pledges.The official has now opened repayment, withdrawal, and necessary asset liquidation channels, urging users to take action as soon as possible: lending users should repay debts, release collateral, and withdraw assets promptly; strategy and LSD users should initiate exits and claims as early as possible; users holding aBTC can continue to use the Aptos-to-B² cross-chain bridge for redemption.To ensure an orderly liquidation process, the announcement specified key timelines. All borrowers with outstanding debts must complete repayments by November 14, 2026, or face collateral liquidation, with the proceeds used to repay lenders. The final deadline for users to make repayments, withdrawals, and release pledges is November 19, 2026, at 23:59 (UTC).After this, the Echo Protocol will officially cease operations, and all remaining positions will enter the final liquidation and settlement process, with the platform only retaining the redemption service of the Aptos-to-B² cross-chain bridge. Since LSD and Strategy assets depend on the request time for underlying pledges/unpledges, the actual time users can claim will be affected by this factor.

Cobo Wallet announced that its App service will officially close on December 1, 2026. Users must complete the transfer of all assets by November 30 at 23:59 and update the Cobo Wallet receiving address set on other platforms.The announcement reminds users that those who do not transfer their assets within the deadline will incur account management fees. This adjustment will directly affect users who are still using the Cobo Wallet App for asset storage and receiving payments; relevant users should promptly confirm their on-chain assets, receiving addresses, and withdrawal whitelist settings on associated platforms.After the App service is closed, if there are remaining assets in the account, Cobo will charge a monthly account management fee. The management fee is calculated based on the asset type, amounting to 2% of the remaining assets in the account, with a minimum charge equivalent to 100 USD per month. Users who fail to complete the asset transfer before the App closes will be deemed to have agreed to this fee arrangement.The announcement does not specify the exact reasons for closing the service, nor does it disclose whether other products or institutional businesses under Cobo will be affected.

Mona El Isa, co-founder of Enzyme, announced that after ten years in the industry, she has decided to exit the sector and close the on-chain asset management company Avantgarde. She stated that Avantgarde was established during the bear market in 2019, served as the core development team for Enzyme, and helped Enzyme achieve self-sustainability after several version iterations. Enzyme has now grown to become one of the fastest-growing fund tokenization platforms.Mona El Isa also mentioned that Avantgarde subsequently provided curation and fund management services for Compound, Gitcoin, SuperRare, NEAR, Decentraland, The Graph, and others, handling transactions worth hundreds of millions and TVL, while ensuring the safety of client assets during a year of severe DeFi security challenges. She plans to take a break before deciding on her next steps and welcomes staying in touch, and she can provide recruitment referrals for team members.

According to Bloomberg, the Brooklyn District Attorney's Office successfully dismantled a multinational cryptocurrency fraud network centered in Eastern Europe, which had long targeted users in the United States, stealing tens of millions of dollars in total.This operation shut down 241 websites related to cryptocurrency fraud and seized 112 servers hosted by companies in Eastern Europe and the United States.

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. As of the time of writing, the wallet still holds ETH worth 766,000 USD.As of the time of writing, the floor price for Pudgy Penguins NFTs is reported at 3.3 ETH, with a 24-hour increase of 6.8%.Pudgy Penguins CEO Luca Netz stated that Abstract is gradually shutting down, and its parent company Igloo Inc. will now focus all its efforts on the development of Pudgy Penguins, Pudgy NFTs, and PENGU.

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 consumer-grade Ethereum Layer 2 network Abstract, supported by Pudgy Penguins' parent company Igloo Inc., announced that it will gradually cease operations and officially shut down its mainnet on December 15, 2026. The official reasons given are stagnation in growth, thin liquidity, limitations in the DeFi ecosystem, and insufficient institutional adoption. Abstract warns users that they must transfer their assets across chains before the shutdown date, or they may lose access to their funds.Abstract stated that the network has deployed over 144 applications and has attracted more than 400,000 users through consumer-grade collaborations with brands such as Red Bull Racing and Disney. However, significant changes have occurred in the industry since the project's conception, and the independent chain model focused on consumer-grade crypto has ultimately proven difficult to sustain. Igloo has continuously funded Abstract for the past 18 months, with CEO Luca Netz revealing that cumulative losses have reached tens of millions of dollars. Igloo is now redirecting resources towards Pudgy Penguins and PENGU.In July 2024, Igloo completed a financing round of over $11 million led by Founders Fund, aimed at developing Abstract and leveraging Pudgy Penguins' distribution capabilities to bring consumers on-chain. The network launched its mainnet in January 2025. Netz stated that Igloo ultimately decided not to issue Abstract tokens and would not continue funding the network at the expense of Pudgy Penguins' business.

In response to the community rumor that "Aptos will shut down its blockchain in the next 6 months," Aptos Labs co-founder and CEO Avery Ching publicly stated that this is "a stupid rumor."The X account that initially published the related news did not provide any official Aptos announcement, governance proposal, or other documents as evidence. When pressed for evidence, the account stated that the information was merely "heard" and reminded to be cautious in interpretation.Additionally, another community account claimed that Aptos had significantly laid off employees over the past year and was facing financial pressure, but that account also admitted that the source of the information was "unreliable," and there is currently no public information to confirm the above claims.Aptos's current public governance records still show network upgrade proposals and executed mainnet function updates, and no official plans to shut down the mainnet have been found.
