The Starknet AMM protocol mySwap disclosed that its mySwap CL protocol suffered a vulnerability attack, resulting in approximately $300,000 being withdrawn from the liquidity pool. The official statement indicated that the mySwap interface has been closed for over 6 months and is no longer accepting new liquidity injections. The affected funds were mainly the remaining LP positions scattered across more than 100,000 positions. The attacker utilized the funds stolen through bridging and obscured the asset flow using Railgun. This attack nearly depleted all remaining liquidity in the protocol.

According to The Block, investment bank Benchmark pointed out in its latest research report that the U.S. Securities and Exchange Commission (SEC) proposed to repeal Rule 611 and Rule 610(e) of Regulation NMS, which could become the "most decisive regulatory change" affecting the market structure of cryptocurrencies and tokenized assets in 2026.The proposal was announced on June 11 and aims to eliminate trading protection and quote constraint rules that have been in place for nearly 20 years in the U.S. stock market. The SEC stated that this move is intended to reduce trading costs and provide greater space for market competition and technological innovation.Benchmark's analysis believes that the current Rule 611 (order protection rule) requires trades to adhere to the National Best Bid and Offer (NBBO), while Rule 610(e) restricts "locked/crossed quotes." These mechanisms are effective in traditional matching systems but create structural constraints for automated market maker (AMM) models in decentralized finance (DeFi).The report pointed out that if the relevant rules are repealed, it will significantly lower the compliance barriers for tokenized stocks and on-chain trading systems, making AMM-based trading models easier to access the U.S. capital market system.In terms of potential beneficiaries, Benchmark specifically mentioned Securitize, believing that it will benefit most directly as a provider of tokenized securities infrastructure, while Coinbase and Galaxy Digital will also benefit from the expansion of trading, market-making, and custody infrastructure. However, the report also emphasized that the rule adjustments do not address all core issues, such as the exchange registration system, custody and clearing framework, and the legal positioning of DeFi-native trading still needs further clarification.The industry generally expects that the subsequent "innovation exemption mechanism" will become a key supporting policy. The SEC has currently opened a 60-day public comment period on the proposal, and the market anticipates that the final vote may take place in early 2027.

According to local media in Hong Kong, on June 5, the Hong Kong police received a report from a man who claimed that he was scammed out of 1.6 million USDT by a counterfeit exchange while exchanging virtual currency, which is worth approximately 14 million Hong Kong dollars. After preliminary investigation, the police classified the case as "obtaining property by deception" and handed it over to the 10th team of the Mong Kok District Criminal Investigation Unit for follow-up, with no arrests made yet. The police remind citizens that obtaining property by deception is a serious crime, and upon conviction, the maximum penalty can be imprisonment for fourteen years.

Galaxy Research Director Alex Thorn posted that the U.S. Securities and Exchange Commission (SEC) plans to abolish Rule 611 "Order Protection Rule" and Rule 610(e) in the National Market System Regulation (Reg NMS), which could become an important turning point for the development of tokenized stocks.Thorn pointed out that Rule 611 requires trades to adhere to the best quotes across the entire market (NBBO), while AMMs cannot route orders in real-time, access low-latency market data, or pause trading due to better quotes existing on other exchanges. Therefore, it has long been difficult to meet regulatory requirements, becoming one of the main structural obstacles for tokenized U.S. stocks to land in the DeFi scenario. He stated that if the future replaces the regulatory requirements for trade-by-trade supervision with brokers' "best execution obligations," on-chain liquidity pools and AMM mechanisms will be more easily incorporated into the compliance framework.Although tokenized securities still face issues such as trading venue registration and clearing and settlement, the SEC's subsequent plan to introduce an "innovation exemption" mechanism is expected to further promote related developments. Thorn believes this is an important step for the SEC to implement the "Project Crypto" roadmap, paving the way for innovations in tokenized stocks, AMMs, and on-chain securities trading by removing key market structure barriers.

A female tycoon in the domestic cryptocurrency circle encountered an investment scam in the United States, resulting in a loss of over $9.4 million (approximately 60 million yuan). Reports indicate that this individual is a certain Lv, the CEO of a computing power technology company in Southwest China, whose mining pool reportedly accounted for about 9% of the global Bitcoin total computing power at its peak.The report pointed out that two brothers, claiming to have a "Middle Eastern royal family" background, carried out the scam by forging identities. One of them claimed to be a "Middle Eastern royal family son-in-law" and asserted that he controlled funds from Middle Eastern families, international business relations, and resources from local governments in the United States; the other mimicked a character from the American drama "Billions," presenting himself as a hedge fund manager. The two also successfully contacted and influenced Michael Smedley, the chief of staff to the mayor of East Cleveland, Ohio, ultimately inducing Lv to sign a cryptocurrency mining field development contract.

The Solana DeFi protocol Raydium officially confirmed that its legacy AMM V3 program pool, which was deprecated in 2021, suffered an unauthorized liquidity removal attack, involving five pools: Sollet USDT-RAY, Sollet ETH-RAY, SRM-RAY, USDC-RAY, and RAY-SOL. The loss amounts to approximately 150,000 RAY, 5,603 SOL, and 893,700 USDC, totaling about 1.34 million USD.Current users are not affected, the attacker's address has been flagged, and the Raydium treasury will cover all compensation.

The United Nations Development Programme (UNDP) recently announced the establishment of the Blockchain Advisory Group (BAG) during the Proof of Talk 2026 in Paris, focusing on optimizing public systems and governance through blockchain technology. The first meeting was chaired by UNDP Deputy Administrator Xu Haoliang, with the initial in-depth topic being inclusive finance and digital finance, discussing obstacles such as fragmented payment systems, limited digital identities, insufficient interoperability, and institutional readiness, while assessing how blockchain can complement existing digital public infrastructure to enhance financial accessibility, efficiency, and transparency.BAG plans to hold two meetings each year to promote cooperation with the blockchain ecosystem around themes such as digital governance and public trust, legal identity and inclusive societies, digital financial services, climate and traceable accountability, digital labor and the future of work. Current members include 26 institutions such as the Ethereum Foundation, Filecoin Foundation, Stellar Development Foundation, Algorand Foundation, Arbitrum Foundation, Celo Foundation, Web3 Foundation, and Kraken.

XRP Ledger developers submitted a draft amendment called "AMM Swappable Curves," which plans to introduce three types of swappable curves for the XRPL native automated market maker: constant product, concentrated liquidity, and StableSwap, with a programmable Smart AMM to be added later. This upgrade aims to allow liquidity providers to choose more suitable pricing curves based on asset types, thereby improving capital efficiency.Concentrated liquidity is suitable for trading pairs where most transactions are concentrated within a specific price range, while StableSwap is more appropriate for assets that are close to a 1:1 exchange, such as stablecoins or pegged assets. Existing AMM pools will continue to use the current constant product model and will not require migration. This proposal is seen as an important step in addressing the shortcomings of the DeFi infrastructure on XRPL.Currently, there are over $3 billion in tokenized real-world assets on the XRPL chain, including a recent pilot for tokenized U.S. Treasury redemptions completed by Ripple and JPMorgan. However, to enable these assets to trade, lend, or generate yield more efficiently, a more mature DeFi liquidity infrastructure is still needed. Nevertheless, this proposal is still in the draft stage and will need to go through the XRPL amendment voting process, which may take several months, and there is still uncertainty about whether it will ultimately pass.

According to the Hunan Daily, on February 9 at around 8 PM, the public security agency in Baojing, Hunan Province, China, received a report from a victim, Mr. Liu, from another province who had been scammed. He claimed that he was defrauded while purchasing virtual currency USDT online, with a total loss of 100,000 yuan. After receiving the report, the Baojing County Public Security Bureau dispatched a team of elite officers to form a special investigation group and began investigating the case overnight.The investigating officers used various investigative methods to ultimately identify the suspect as Shi. Upon investigation, it was found that the suspect Shi had no fixed income and did not possess qualifications for virtual currency trading. To defraud others, he collected screenshots of others trading coins online, forged false profit records, and impersonated a senior "coin dealer" to gain their trust. Victim Mr. Liu believed him and transferred 100,000 yuan to the account designated by Shi. After receiving the payment, Shi did not deliver the virtual currency; instead, he used part of the funds for gambling and squandered the rest, splitting and hiding the remaining funds.The investigating officers quickly identified Shi's identity and activities by accurately analyzing the flow of funds and comprehensively securing evidence related to the case. They decisively acted on the night of the report and successfully apprehended Shi. The next day, the case was officially filed for investigation. After solving the case, the police consistently adhered to the principle of "solving the case and recovering losses equally," patiently conducted legal policy education, and actively mobilized the suspect's family to cooperate in the restitution, ultimately recovering the full amount of 100,000 yuan involved in the case. On the morning of May 14, the 100,000 yuan of fraudulently obtained funds was fully returned to victim Mr. Liu. Currently, the suspect Shi has been subjected to criminal coercive measures for suspected fraud, and the case is under further investigation.

According to a report by Shangguan News, on May 17, 2026, an elderly man in his 70s, Mr. Gong, from Shuxin Town, Chongming, Shanghai, was deceived by a scammer posing as an "investment mentor" on a short video platform. He was lured into investing in Bitcoin with the bait of "low investment, high returns" and attempted to withdraw 100,000 yuan in cash for transfer at different bank branches twice.After noticing the unusual behavior, the bank teller activated the anti-fraud warning mechanism and coordinated with the police to intervene and dissuade him. The police explained to the elderly man, using real cases, that virtual currency trading and speculation are explicitly prohibited in the country, and that so-called "Bitcoin investments" are all scams. They helped him delete the fraudulent software and block the scammer on WeChat on the spot. After two rounds of patient persuasion from the police and the bank, the elderly man ultimately recognized the scam and gave up the transfer.

According to on-chain analyst Yu Jin's monitoring, the suspected investment fund Gamma Fund address transferred 5,480 ETH to Binance, worth 11.93 million USD.In just over 2 days, they transferred a total of 11,035 ETH (24.46 million USD) to Binance, essentially selling all 11,215 ETH that were bought at the bottom of 1,999 USD in March, making a profit of 2.4 million USD.

According to on-chain analyst Yu Jin (@EmberCN), the suspected investment fund address gammafund.eth redeemed 5,555 ETH from ether.fi about 6 hours ago, worth approximately $12.53 million, and transferred it to Binance.This address previously purchased 11,215 ETH at a price of about $1,999 each in March this year, totaling approximately $22.42 million; based on the cost corresponding to this transfer, it has an unrealized profit of about $2.87 million. Additionally, this address currently has about 5,500 ETH still in the redemption application, which may be completed next week.

According to 10x Research analysis, since mid-January, the total gamma exposure of Bitcoin has remained negative, currently reaching -3.2 billion dollars at the strike price of 82,000 dollars. In a negative gamma environment, market makers are forced to trade in the direction of the trend, accelerating buying during price increases and accelerating selling during price decreases, which exacerbates price volatility.As the options expiration on May 29 and June 26 approaches, the negative gamma suppression effect is expected to gradually dissipate, and the downward bias of Bitcoin will subsequently ease. Currently, the market demand for call options is significantly higher than for put options, and institutions expect that market sentiment will shift from bearish to bullish at that time.

BTC IV 39%, ETH IV 55%; ETH Skew is at a critical turning point------the mid to long term stabilizes at +2 to +5, while the short term has repeatedly dropped to -10 but quickly returned to zero. If ETH stabilizes above $2,400, the short term turning positive will resonate with the mid to long term, confirming a shift from event hedging to upward chasing. The BTC/ETH GEX Term Structure shows that the near-month Gamma has clearly turned positive, with ETF inflows and Call accumulation driving a positive Gamma slow bull structure------under a Long Gamma environment for market makers, the short term is inclined towards high-level fluctuations and slow increases, with IV retreating. Bull Call Spread and selling Put strategies are dominant, but the far month retains negative Gamma reflecting ongoing tail hedging demand. In terms of block trades, 1,001.8 BTC 5/8 expiration $88K Calls were traded, and 14,288 ETH 5/15 expiration $2,600 Calls were traded, indicating clear bullish signals from institutions.Gate has launched the "Rising Star Trader Support Program" for options, with a total prize pool of $25,000 USDT.
