Vietnam plans to allow SMEs to use digital assets and virtual assets as collateral for bank loans
ChainCatcher news, according to Viet Nam News, Vietnam's Ministry of Finance proposes in the draft amended "Small and Medium-sized Enterprise Support Law" to allow SMEs to use digital assets, virtual assets, intellectual property, intangible assets, and future-forming assets as collateral for bank loans, aiming to improve financing accessibility for private enterprises and tech startups.

The Vietnamese Ministry of Finance stated this policy aims to unlock resources in the private economy and align with Resolution No. 68-NQ/TW.
Aave publishes Kelp rsETH bridge attack post-incident investigation
ChainCatcher news, regarding the April 18th attack on the Kelp rsETH LayerZero V2 bridge, Aave published a post-incident investigation on X, emphasizing that the exposure primarily stemmed from third-party bridge infrastructure, not the protocol itself. The attacker used an RPC poisoning attack, targeting a single validator of LayerZero, and forged a cross-chain message. This led to the release of 116,500 rsETH on the Ethereum side without actual burning on Unichain. The attacker subsequently deposited the stolen rsETH into Aave V3 (Ethereum Core and Arbitrum), borrowing approximately 82,650 WETH and 821 wstETH.
The Aave Protocol Guardian and Risk Steward immediately implemented protective measures for the rsETH and WETH reserves. Currently, in the affected V3 deployments, the WETH and rsETH markets are operating normally. The attacker's rsETH on Arbitrum has been burned, the LayerZero OFT adapter has been fully replenished in five batches, rsETH support has been fully restored, and Kelp has reopened withdrawal, bridging, and claim functions for rsETH. The WETH LTV in the affected markets has been reset to pre-attack values, and aside from rsETH, Aave V3 is fully operational across all markets.
Arbitrum DAO has voted to authorize the transfer of the frozen ETH to Aave LLC, currently awaiting on-chain execution. The court is still deliberating the merits of the restraining order, and Aave LLC will continue to comply with the order during the court's consideration. Ongoing projects include: Llama Risk's Aave risk framework, bridge assessment framework, release of evaluation reports for currently listed assets, on-chain execution of the Arbitrum DAO vote, and the court's deliberation on the restraining order.
Chinese Qingdao man who stole 107 BTC while "helping acquaintance register wallet" convicted of theft, sentenced to 10 years 9 months
ChainCatcher news, the People's Procuratorate of Licang District, Qingdao City, Shandong Province, China, recently handled a bitcoin theft case. Defendant Zhang Moumou obtained the mnemonic phrase while assisting an acquaintance in registering a virtual currency wallet, later transferring away 107 BTC in multiple transactions, equivalent to over RMB 50 million at current market prices. Zhang Moumou argued his actions constituted "protective takeover," but prosecutors found he transferred the stolen BTC through multiple trading platforms and converted it into over RMB 660,000. The Licang District Court sentenced Zhang Moumou to 10 years and 9 months in prison for theft in the first instance, with a fine of RMB 100,000; the second instance upheld the original judgment.
Reports indicate that the case prosecutor strictly followed laws and judicial policies, conducting in-depth analysis. They concluded that while China's regulatory policy denies the legal tender status of virtual currency, it does not deny its property attributes, nor does it prohibit citizens from legally holding and transferring it. Bitcoin requires investment in computing power, capital, and other costs to obtain, possessing economic value; rights holders can achieve exclusive control and management through private keys and mnemonic phrases, aligning with the core characteristics of "property" in criminal law and making it a viable target for theft crimes. In determining the amount, due to the lack of official pricing for virtual currency, the Licang District Procuratorate abandoned market price estimation, using the actual proceeds from selling the stolen goods, RMB 660,000, as the theft amount, achieving accurate conviction, appropriate sentencing, and unity of crime, responsibility, and punishment.
Santiment: Bitcoin long/short ratio surges to 2.23, hitting yearly high, may signal short-term pullback
ChainCatcher news, crypto sentiment platform Santiment published an analysis stating that the ratio of positive to negative comments on Ethereum has shifted from strong FOMO sentiment in late April to clear FUD sentiment now. Harvard University fully divested its $87 million Ethereum ETF holdings one quarter after purchase; an Ethereum Foundation researcher announced resignation; and David Hoffman publicly stated he is stepping away from the Ethereum project. The Santiment team interprets this trend as a moderately bullish signal, similar to the sharp rise following the market sentiment low in mid-2023.
Despite the panic, the number of non-empty Ethereum wallets remains high at 192.92 million, over three times more than Bitcoin's approximately 59 million. DeFi and staking transaction activity spiked at the beginning of the year, later normalizing, but new wallet creation continues at a healthy pace. Foundational data on holders and activity does not support the notion that "the Ethereum network is dying." Additionally, the Bitcoin long/short ratio is as high as 2.23, reaching the highest level since 2026. The previous two highest daily long/short ratios coincided with short-term price pullbacks, while extremely low long/short ratios marked local bottoms. The current optimism starkly contrasts with the short fund flows in ETFs, thus caution is advised.
US SEC files lawsuit against Privvy founder over alleged $12.3 million crypto scam
ChainCatcher news, according to The Block, the US SEC filed a lawsuit in Houston federal court, alleging that Cypress, Texas resident Nathan Fuller operated a cryptocurrency scam project involving up to $12.3 million, which used a fake artificial intelligence trading bot.
Nathan Fuller told investors that his proprietary AI-based bot could automatically scan cryptocurrency exchanges, capture tiny price gaps through high-frequency arbitrage, and promised returns of 40% to 50% within 30 to 45 days. Some investors were even told they could get guaranteed returns of over 100% in 21 days.
The SEC alleges that Privvy Investments LLC founder and sole member Nathan Fuller raised these funds from about 150 investors across nine states and two foreign countries between October 2022 and mid-2024. He also operated under the alias "Gateway Digital Investments."
Allegedly, only about 3% of the funds were actually used for cryptocurrency trading, while Fuller himself misappropriated at least $6.2 million and paid about $5.5 million to early investors in a Ponzi-like scheme.

Three Years Later: Revisiting My 2023 Predictions on ChatGPT
On March 6, 2023, soon after ChatGPT emerged and before GPT-4 was released, Sarah and I conducted an interview about ChatGPT—the third episode of the "Plain Talk" series of Traders' Talk (Plain Talk about ChatGPT podcast is released, welcome to listen).
At that time, ChatGPT had just come out, and very few people had actually used it. This three-hour interview later topped the ChatGPT category on Xiaoyuzhou. I made about twenty judgments and predictions in it, purely based on intuition and limited information, with little data. The full transcript of that interview remains on the public account.
It's now late May 2026, three years have passed, and AI has grown into something unimaginable back then.
