According to CoinDesk, European stablecoin issuer StablR has suspended the minting and redemption of USDR and EURR due to a hacker attack, and has requested exchanges to stop trading and deposits/withdrawals of the two currencies. The attacker exploited a vulnerability in its Ethereum 1-of-3 multi-signature wallet with a low threshold, compromised a single private key, added themselves as an administrator, and removed the original signers, resulting in the over-issuance of approximately 8.35 million USDR and 4.5 million EURR, valued at approximately $13.5 million at the pegged price, with actual cashing out around $2.8 million.The incident led to both stablecoins being under-collateralized, no longer meeting the MiCA requirement of a 1:1 full reserve. USDR briefly depegged but recovered to about $0.994, while EURR fell to about $0.548. StablR stated that it has initiated an investigation and will report to the Maltese regulators and relevant authorities.

The decentralized stablecoin USDD announced a deep strategic cooperation with the smart economic infrastructure platform B.AI. Both parties will integrate DeFi and AI to jointly build a value transmission system compatible with general AI. This cooperation marks a key breakthrough for USDD in the AI payment field and officially opens the curtain on the development of the AI autonomous economic ecosystem.After the cooperation is implemented, USDD will become the core payment network of the B.AI platform, leveraging advantages such as stability, on-chain transparency, and cross-chain efficiency to provide programmable on-chain settlement services for AI entities, addressing the shortcomings of traditional payment models. With the combined technical and ecological strengths of both parties, it will enable the entire process of identity verification, autonomous transactions, and value settlement for AI entities, effectively lowering the threshold for the commercialization of AI.

THORChain has released its fourth update regarding the attack incident on May 15, and the proposal ADR028 has been announced, with voting for node operators now open.According to the recovery plan, the protocol will first absorb losses through its own liquidity, with the remaining portion to be shared by synthetic asset holders; the specific distribution ratio of the two is still under evaluation. The protocol's own liquidity will be reduced to zero, and will be gradually replenished through system revenue. This plan will not issue or sell RUNE, nor will it dilute any holders.On the technical side, GG20 will be temporarily retained and has completed patch upgrades. Trading will resume after the vulnerabilities are fixed and node rotation is successfully conducted, with a future release pace that is slower and more security-conscious. Innocent nodes located in the same vault as the attacker will be protected, while the attacker nodes will be fully confiscated. The recovered RUNE will be paired with the recovered assets, and any excess will be destroyed.The protocol also offers a white hat bounty to the attacker to recover funds; if some are returned, the recovery plan will be adjusted proportionally. THORChain remains neutral and permissionless, and there will be no review of the attacker's Swap transactions after trading resumes. Node operators are currently voting on the proposal direction, and the numbers in the ADR are only indicative, with adjustments to be made through Mimir later.

The cross-chain network Everclear officially announced on social media that it has decided to end the operations of the Everclear Foundation and Labs, and to stop product development. Currently, the protocol has been shut down, and the Everclear UI and chain have ceased operation. The team stated that the remaining TVL in the protocol has been fully withdrawn, and to their knowledge, no user funds are trapped.Regarding the reasons for the shutdown, Everclear stated that although the monthly trading volume had previously reached $500 million, the team failed to establish sufficient commercial depth and convert it into effective revenue due to users' high price sensitivity in the cross-chain solver field. Additionally, the team exhausted its funds (runway) during the transition to a B2B2C model over the past six months, and several acquisition proposals explored were also unsuccessful.For future arrangements, Everclear is conducting an orderly liquidation to address outstanding debts. The team stated that if there are remaining funds after the debts are settled, they will explore repurchasing existing tokens, with a potential total repurchase amount estimated between $50,000 and $200,000, but this has not yet been finalized. Furthermore, the foundation is considering open-sourcing the protocol's intellectual property (IP) to give the DAO the option to continue advancing work under new management; currently, the DAO itself is still operational.

The DAO infrastructure service provider Syndicate announced that it will gradually cease operations. It stated that after five years of continuous development of on-chain developer infrastructure, the Rollup market has undergone fundamental changes. Currently, the Rollup market size has significantly shrunk, with some Rollup projects gradually shutting down, and the market has shifted from EVM Rollups to custom chain models built from scratch by consulting teams, resulting in a significant decline in reusable technology and network value.Syndicate stated that its system consists of two parts: Syndicate Labs, responsible for development, will shut down, while the independent entity Syndicate Network Collective (Wyoming DUNA), which holds SYND tokens and has governance rights, will continue to exist, and SYND governance will not be affected in the short term.In addition, Syndicate emphasized that this decision to cease operations is unrelated to recent cross-chain security incidents, and affected users and SYND holders have received full compensation through treasury reserves, while team and investor tokens are still locked.

SocialFi trading card game (TCG) fantasy.top announced that it will close at the end of June after two years of operation.

According to WSJ, Anthropic's revenue is expected to reach $10.9 billion in the second quarter, more than doubling from $4.8 billion in the first quarter, and it will achieve profitability at the operational level for the first time. Due to its enormous computing power requirements, the company may not be able to maintain profitability throughout the year; the operational profits have already accounted for the costs of training new models but do not include equity incentive expenses.As part of an ongoing financing round, Anthropic disclosed this data to investors, and this round of financing is likely to raise its valuation above that of OpenAI. Last summer, Anthropic shared financial data with investors, which indicated that the company might not achieve full-year profitability until at least 2028.

The TON Network expansion project TAC has disclosed that a security incident occurred with the TON-TAC asset bridge on May 11. Four days later, approximately 80% of the affected assets have been returned. TAC today released a post-incident analysis report detailing the events. The root cause of the vulnerability was a lack of a single verification in the sorter software: the attacker deployed a counterfeit Jetton wallet on TON, and the sorter accepted the counterfeit tokens because it did not verify the code hash of the sender's wallet. The total loss was approximately $2.86 million, involving USDT, BLUM, and tsTON. Following a public appeal, about 90% of the assets were returned to the multi-signature address controlled by TAC on May 14, with the remaining 10% retained by the attacker.The cross-chain bridge remains paused, awaiting independent review of the repaired sorter software by the auditing party and TON partners. Cross-chain operations will resume once the verification of the repaired software is completed and the gap is filled with recovered assets and TAC Foundation token reserves. Due to the need for multi-party coordination, a precise timeline cannot be provided. The remaining funding gap will be filled by the TAC Foundation treasury, ensuring that users and protocols incur no financial losses. TAC reminds users that official updates are only published through this account and Telegram, and any unsolicited "recovery" or "support" private messages are scams.

The open-source data visualization tool Grafana has released the latest progress on the investigation of the security incident on May 16. The investigation found that this incident was limited to the GitHub environment of Grafana Labs, including both public and private source code as well as internal GitHub repositories, and did not affect customer production systems, operations, or the Grafana Cloud platform. The downloaded content, in addition to the source code, also included some repositories used by the team for collaboration and storage of internal operational information and business details, involving business contact names and email addresses, rather than data from production systems or the cloud platform.Grafana Labs has made it clear that the codebase was downloaded but not tampered with, and currently, customers and open-source users do not need to take any action. The incident originated from a TanStack npm supply chain attack conducted through the Mini Shai-Hulud campaign. Grafana Labs detected malicious activity on May 11 and initiated an emergency response, but a credential was overlooked, allowing the attacker to gain access. After receiving a ransom demand on May 16, the company decided not to pay the ransom and has rotated automated credentials, implemented enhanced monitoring, audited all commits since May 11, and significantly strengthened GitHub security configurations. The company has notified federal law enforcement, and the investigation is ongoing.
