“New Stock God” Serenity posted on X, seemingly responding to the potential investigation into Sivers, stating that Sivers (SIVE) should fully transform into a U.S. company, with Nasdaq listing as the first step—given that the company already possesses a U.S. capital structure, a significant equity stake, and support under the CHIPS Act. Such a transformation would deliver higher valuation premiums and M&A opportunities. Meanwhile, negative reporting by Swedish local media—allegedly influenced by short sellers—is hindering the development of AI photonics, whereas the U.S. market offers greater financing opportunities and support from institutions, funds, and indices.
Hong Kong Securities and Futures Commission (SFC) Chairman Wong Tin-yau revealed in a recent speech that Hong Kong has systematically expanded the scope of products and services available from licensed institutions. This includes offering more diversified product options for professional investors, piloting secondary market trading of tokenized products, launching virtual asset-related financing services, and establishing a regulatory framework for virtual asset leveraged products. The 12 licensed virtual asset trading platforms in Hong Kong recorded a total trading volume exceeding HKD 640 billion in 2025, with the trading volume in the first quarter of this year surging nearly threefold year-on-year. Additionally, brokerage firms engaged in virtual asset-related businesses saw their corresponding commission income grow by over 80% year-on-year last year.On the institutional front, Hong Kong will optimize its comprehensive regulatory framework for virtual assets, covering key areas such as custody, trading, asset management, and investment advisory. The public consultation on the relevant licensing regime has been completed, and legislative proposals will be finalized with the Hong Kong Treasury Bureau. The target is to submit a bill to the Legislative Council in 2026, aiming to establish a regulatory system that is fully aligned with international standards and strictly adheres to the principle of "same business, same risks, same rules."
the Qingdao Licang District Procuratorate issued an announcement stating that the defendant, surnamed Zhang, took advantage of an opportunity to register a virtual currency wallet on behalf of the victim to obtain the seed phrase, and subsequently transferred 107 Bitcoins from the victim, surnamed Feng, in multiple batches during the early morning hours.

According to Viet Nam News, Vietnam’s Ministry of Finance has proposed in the draft amendment to the Law on Support for Small and Medium Enterprises (SMEs) that SMEs be permitted to use digital assets, virtual assets, intellectual property, intangible assets, and future-formed assets as collateral for bank loans—aiming to improve access to financing for private enterprises and tech startups. The draft also encourages credit institutions to base lending decisions more heavily on credit ratings, business plans, market expansion potential, and corporate cash flow, thereby reducing reliance on traditional forms of collateral such as real estate. The Ministry of Finance stated that this policy seeks to unlock resources within the private economy and align with Resolution No. 68-NQ/TW.
Aave has published a post-mortem of the April 18 rsETH incident, stating that the rsETH LayerZero V2 cross-chain bridge of liquid staking protocol Kelp accepted a forged message during a cross-chain transfer from Unichain to Ethereum. This caused the adapter on the Ethereum side to release 116,500 rsETH without a corresponding burn on the Unichain side. Aave stated that the attack occurred on a third-party cross-chain bridge infrastructure. However, the attacker deposited the stolen rsETH into 8 Aave V3 positions, borrowing 82,650 WETH and 821 wstETH, which impacted the Aave market.Aave stated that the attacker's rsETH on Arbitrum has now been burned. The LayerZero OFT adapter has replenished 116,131.72 rsETH in 5 batches, and the asset backing for rsETH has been fully restored. The affected WETH and rsETH markets have returned to normal.

According to Cambodian media outlet Kohsantepheap Daily, Yang Weixin, a 53-year-old Chinese national and real estate company owner, was kidnapped by a criminal gang in Phnom Penh. On the early morning of May 30, suspects used the victim’s mobile phone to demand $2 million worth of cryptocurrency from his wife. After failing to receive the ransom, they murdered the victim and dumped his body inside a car. Surveillance footage shows that three suspects forcibly abducted the victim from the parking lot of his residence on the evening of May 29. Local police have confirmed the case as a kidnapping-for-ransom resulting in death, and the investigation is ongoing.
According to Cointelegraph, U.S. Senator Cynthia Lummis stated that if Congress fails to pass the digital asset market structure bill—the Digital Asset Market Clarity Act (the “CLARITY Act”)—the United States risks falling behind other countries, including China, in leadership on crypto regulation. She noted that enacting a comprehensive crypto regulatory framework would help ensure that other nations do not write the rules for the next era of finance. Earlier, in May, the Senate Banking Committee voted to advance the bill; however, it still requires passage by both chambers of Congress and the President’s signature before becoming law.
a16z Crypto published an article analyzing the unique value and challenges faced by prediction markets. Prediction markets allow participants to trade on event outcomes, aggregating dispersed information through price signals to provide real-time probability estimates for future events. Unlike traditional polls, prediction markets offer real-time update capabilities and incentivize participants to stake capital on their information, thereby improving prediction accuracy.The article points out that prediction markets are not only used by enterprises for product launches and research experiment forecasts, but also serve as "wisdom of the crowd" information sources for media outlets, covering events ranging from geopolitics to AI model performance. Their core advantage lies in providing independent probability estimates for specific events, rather than relying on indirect signals from overall asset price movements.However, prediction markets still face infrastructure and market design challenges, including event verification, contract settlement, the sufficiency of participant information, and potential manipulation risks. a16z believes that if these issues are resolved, prediction markets could become important tools for decision-making and information aggregation, expanding the ability of finance and society to gain insights into future events.
: Jonas Myrdal, a prosecutor at the Swedish Economic Crime Authority, stated that regarding a post on social platform X about Sivers Semiconductors (SIVE) considering a dual listing in the US leaking out early and being officially confirmed by the company approximately 48 hours later, he believes this is not a coincidence but highly likely involves an information leak.Jonas Myrdal pointed out that the relevant information was published and continuously promoted on platform X by an anonymous account with approximately 200,000 followers before its official disclosure. This subsequently triggered a sharp, several-fold increase in the company's stock price within a short period. This behavior pattern is similar to a previous case involving "pump-and-dump" manipulation, in which three individuals were convicted of serious market manipulation offenses. He further recommended that Nasdaq should investigate this incident and assess whether it violates the EU Market Abuse Regulation (MAR). Currently, the source of the suspected information leak is still under investigation.Previously, "New Stock God" Serenity posted on platform X seemingly "touting" Sivers, and stated that after further reviewing Sivers Semiconductors' latest earnings conference call, they are optimistic about its prospects. The company's management indicated that "in a super-cycle where demand far exceeds supply, viewing ecosystem partners as competitors is not the correct approach," reflecting the current strong demand in the photonics industry. Additionally, the photonics business pipeline has grown rapidly over the past five months, driving an overall revenue pipeline increase of 77%. (Marketscreener)
digital asset management firm Grayscale stated in its latest report that the decentralized trading platform Hyperliquid is rapidly evolving from a crypto perpetual contract exchange into a blockchain-based financial infrastructure platform. In the future, it may even challenge the traditional derivatives trading and exchange systems, growing into a "financial services giant."The report shows that Hyperliquid generated approximately $800 million in revenue in 2025, with a full-year perpetual contract trading volume of about $2.9 trillion and open interest of roughly $7 billion, capturing a significant share of the crypto derivatives market. Grayscale believes the platform is no longer limited to crypto trading. Through the HIP-3 and HIP-4 systems, it is expanding into tokenized stocks, commodities, and prediction markets, gradually building a 24/7 on-chain trading infrastructure.In another report, FalconX also pointed out that Hyperliquid is competing with traditional derivatives exchanges like the CME Group, as well as prediction market platforms such as Kalshi and Polymarket, and is making progress in new markets like Pre-IPO.The report also emphasized that regulation remains a key variable. Although Hyperliquid currently restricts access for US users, as the regulatory framework gradually clarifies and institutions like Coinbase, Robinhood, and Kraken explore perpetual contract products, this sector may see broader growth potential in the future.

BofA believes that current global corporate earnings expectations have clearly outpaced macroeconomic fundamentals, and the market is betting that AI will reshape the global labor market and boost corporate profit margins—much like China’s accession to the WTO did in its time. However, this logic still faces multiple risks related to demand, costs, and policy.
Odaily Odaily founder Rand posted on platform X, stating that with the assistance of on-chain detective ZachXBT, the team has identified the root cause of the recent cUSDC freeze incident, which is unrelated to the Zama protocol itself or privacy technology. The incident originated when a wallet address associated with the Overnight Finance hack deposited over $12.5 million USDC into Zama's cUSDC wrapper contract. Since the address was not on any sanctions list at the time of deposit and was not flagged by KYT (Know Your Transaction) tools, the funds were able to enter the protocol.Rand stated that law enforcement agencies recently issued asset restriction orders against several wallets linked to the hacker. At that time, the cUSDC wrapper contract held relatively small funds, with over 99% coming from the aforementioned hacker address. Consequently, the court ordered the freezing of the entire wrapper contract to restrict the movement of the related funds. Rand emphasized that this measure is not a sanction against Zama or privacy protocols, but a common judicial freezing measure in the DeFi space.To cooperate with the investigation, Zama has suspended the operation of the cUSDC, cUSDT, and cWETH contracts until the investigation is complete, all involved addresses are identified, and corresponding measures are taken. Rand reiterated that Zama adheres to the principle of "compliant confidentiality" and will not tolerate any illegal activities. He also indicated that a more detailed post-mortem of the incident and a plan for handling similar requests in the future will be released subsequently.
privacy computing protocol Zama posted on the X platform stating that Circle's compliance system flagged an external deposit address. Because this address held funds in the cUSDC contract, the entire cUSDC contract was included in a routine freeze measure. Zama emphasized that this incident is "collateral damage" caused by the affected address and is not a sanction action targeting the Zama protocol. Currently, Zama's legal team has intervened and is working with relevant parties to isolate the flagged address and restore normal access to funds for other unaffected participants as soon as possible.
Odaily Planet Daily reports: Multicoin Capital co-founder Kyle Samani posted on X platform analyzing three possible scenarios for the development of Kalshi and the US crypto perpetual contract market:1. Kalshi's previous efforts are irrelevant: Because the US market itself can already offer unregulated perpetual contracts.2. Protocols must pass the eight decentralized tests of the CLARITY Act: If the CLARITY Act passes smoothly, protocols can offer perpetual contracts in the US without registering as a DCO (Designated Contract Organizer) and DCM (Designated Contract Market).3. Products can still attract users but cannot legally enter the US financial system: Even with user recognition, protocols may still be unable to distribute within a compliant framework.Analysis suggests that these potential outcomes highlight the complex relationship between current US derivatives regulation and decentralized protocols, as well as the uncertainty surrounding the compliant implementation of innovative financial products.
the U.S. Department of State announced the designation of two Brazilian organizations, Comando Vermelho (CV) and Primeiro Comando da Capital (PCC), as "Specially Designated Global Terrorists (SDGTs)." They plan to officially designate them as "Foreign Terrorist Organizations (FTOs)" starting June 5, 2026. These organizations have been accused of using digital currencies for money laundering, with PCC reportedly using Bitcoin mining as a cover for laundering funds.Previously, Brazil passed a new law in March of this year allowing confiscated crypto assets to be used for public safety expenditures. This move marks Brazil's shift in viewing crypto assets from a potential reserve tool to law enforcement resources, strengthening efforts to combat crimes by PCC, CV, and other organizations, while advancing the judicial system's capabilities in regulating and disposing of digital assets.
: John Wang, head of Kalshi's crypto business, posted on X platform, saying in a joking tone that "Kalshi is not a cryptocurrency company."John Wang stated that Kalshi is the first regulated platform in the United States to legally offer crypto perpetual contract trading; cryptocurrency-related prediction market trading volume accounts for approximately 70% of the platform's total trading volume, making it the second-largest business category. Meanwhile, Kalshi also serves as a liquidity layer for Coinbase and Phantom's frontend, and only accepts cryptocurrency for international deposits.He once again joked at the end: "That's right, Kalshi is not a cryptocurrency company."
South Korea’s Financial Intelligence Unit (FIU) plans to discontinue its push for mandatory Suspicious Transaction Reports (STRs) for large cross-border virtual asset transfers and peer-to-peer wallet transfers, while continuing to expand the scope of Travel Rule oversight to further strengthen digital asset transaction tracing.
