According to The Block, the T3 Financial Crime Unit (T3 FCU), jointly established by Tether, TRON, and TRM Labs, announced that since its establishment in 2024, it has frozen over $450 million in illegal crypto assets globally.The unit intercepted illegal proceeds in 2025, with a year-on-year increase of 43.9%, covering 23 jurisdictions including the United States, Spain, and Germany, and was recognized by the Financial Action Task Force (FATF) as "an important resource for global law enforcement agencies."T3 FCU has participated in various criminal investigations, including exchange hacks, North Korea-related activities, terrorist financing, and violent crime cases, and assisted the Brazilian Federal Police in freezing over $5.989 billion in assets, including 4.3 million USDT.

U.S. Judge Margaret M. Garnett in New York postponed the ruling on Aave's emergency application on Wednesday, which aims to unfreeze $71 million in ETH related to the Kelp DAO hacking incident, and requested both parties to submit supplemental briefs before the hearing on June 5. Aave is attempting to reclaim the $71 million in ETH frozen on Arbitrum to assist in the asset recovery efforts from this hacking incident—Kelp DAO suffered losses of up to $293 million from the hack, making it one of the most severe security incidents in the DeFi space this year.However, the U.S. law firm Gerstein Harrow LLP submitted a restraining order to the court in early May, claiming that its client has rights to the aforementioned funds. Aave then filed an emergency motion to lift the freeze, warning that if the funds are not released in a timely manner, it could lead to user liquidations and potentially impact the entire DeFi market. Judge Garnett noted in her ruling that Aave failed to adequately explain how user funds would incur "compound losses" if the restraining order remained in place. She also acknowledged the complexity of the case, the risks faced by the victims, and requested both parties to provide supplemental statements on six key issues, including: whether the hacking transaction is subject to New York state sanctuary principles, the legal distinctions between fraud and theft and what rights the hacker has over the stolen assets, which laws apply to determine the priority of claims for frozen assets, whether constructive trusts are an appropriate remedy, and whether Aave or Arbitrum can identify individual victims and proportionally return assets. Both parties must submit supplemental briefs by May 22.Meanwhile, the overall compensation work for Kelp DAO is progressing. Kelp and Aave announced on Tuesday that the rsETH held by the hacker has been destroyed on Arbitrum, and approximately $278 million in loss tokens will be restored within the next two weeks through the funds of the Aave Recovery Guardian multi-signature wallet. Once the relevant smart contracts are reactivated, all functions of rsETH will return to normal.

On May 5, the Hong Kong High Court approved the application of the Department of Justice to issue an injunction against 42 individuals and companies, including Chen Zhi, the founder of the Prince Group, who are suspected of operating a scam park in Cambodia, freezing a total of HKD 8.938 billion in assets. The frozen assets include deposits in bank and securities accounts, stocks, and properties. Among them, Chen Zhi's personal assets in Hong Kong exceed HKD 6.36 billion. Zhou Yun, who assists in managing his assets, has total assets exceeding HKD 2 billion, and her personal accounts hold the equivalent of HKD 15.92 million in Hong Kong dollars, euros, and Bitcoin. In addition, related personnel from the Prince Group, Hu Xiaowei and Li Tian, have approximately HKD 400 million and HKD 172 million in assets frozen, respectively. The court will reconvene on August 3 to decide whether to extend the injunction.

According to Cointelegraph, Tether has frozen over $514 million USDT in the past 30 days, involving 370 addresses. Among them, the Tron chain froze approximately $506 million, while the Ethereum chain froze about $8.73 million.An analysis of data from 2025 by BlockSec shows that Tether has blacklisted a total of 4,163 independent addresses on the Ethereum and Tron chains, freezing a total of $1.26 billion USDT.

According to official news, Aave LLC has submitted an emergency motion requesting the withdrawal of the asset freeze notice issued to Arbitrum DAO on May 1, 2026. This notice attempts to seize approximately $71 million worth of ETH, which belongs to the victims of the attack on April 18.Aave stated that attackers do not gain legal ownership of stolen property merely by stealing it, as the law clearly stipulates. The assets being recovered are intended to be returned to users affected by the attack on April 18, 2026. Freezing these assets harms the users that the recovery efforts are supposed to protect.Aave has requested the court to hold an emergency hearing and temporarily lift the freeze order, while continuing to work with the Arbitrum community and DeFi United to compensate the affected users.

MegaETH executive PaperImperium disclosed on platform X that documents from the U.S. District Court for the Southern District of New York show that the U.S. court has issued an injunction to Arbitrum DAO, prohibiting it from transferring approximately $71 million in ETH assets that were frozen during the KelpDAO hacking incident. The plaintiffs are attempting to use these funds to enforce unpaid judgment compensation related to North Korea's involvement in terrorism, kidnapping, and other cases over the years, and have applied to issue legal notice to Arbitrum DAO through alternative service, treating it as a "partnership organization" that can be held accountable.The court documents also indicate that Arbitrum DAO has a Security Council governed by ARB holders, which has the ability to take action in emergencies. Therefore, if relevant members refuse to cooperate, they may face legal liabilities such as contempt of court. The market believes that this case may become an important precedent for the U.S. judicial system directly constraining DAO governance structures and further highlights the compliance pressure on DeFi protocols within the real legal framework.

According to market news, the Arbitrum committee voted to unfreeze $71 million worth of Ethereum to mitigate the $290 million loss caused by the Kelp DAO vulnerability.

Tether announced that it has supported the U.S. government's freeze of over $344 million USDT, involving two wallet addresses. This freezing action was carried out in collaboration with the U.S. Department of the Treasury's Office of Foreign Assets Control (OFAC) and U.S. law enforcement agencies, aimed at preventing further movement of funds.The freeze was based on information provided by multiple U.S. law enforcement agencies, linking these addresses to illegal activities. Tether stated that when wallet addresses are associated with sanctions evasion, criminal networks, or other illegal activities, the company will take freezing measures. This has now become Tether's routine response to legitimate requests from U.S. and global law enforcement agencies.Tether CEO Paolo Ardoino stated, "USDT is by no means a safe haven for illegal activities. We take immediate action when there are credible links to sanctioned entities or criminal networks. Recent events have shown what can happen when platforms fail to act swiftly, law enforcement fails, users are exposed, and trust is lost. Our approach is different; we combine blockchain transparency, real-time monitoring, and direct coordination with law enforcement agencies to prevent the flow of funds. This is a responsibility we take very seriously as one of the largest issuers in the market."This action is part of Tether's cooperation with U.S. law enforcement agencies. The U.S. Department of Justice had previously confirmed Tether's support in law enforcement actions, successfully seizing nearly $61 million and approximately $225 million in "pork scam" funds.

According to MLM monitoring, Tether has just frozen two wallets on the Tron chain, involving funds of up to 344 million USDT.

The Spark strategy chief monetsupply.eth tweeted criticism of Aave's decision to unfreeze the core Ethereum WETH market, arguing that this decision is poorly considered under current conditions. After the unfreezing, it will allow LST/LRT holders to establish extremely high-yield looping positions, resulting in continuous liquidity shortages for aEthWETH, making it difficult for ordinary users to withdraw normally.Taking weETH looping as an example: weETH is currently trading at a 0.5% discount, and if it returns to par within a month, the implied yield is about 6%. Combined with the basic staking yield, the total yield can reach 8%. Meanwhile, the maximum borrowing rate for core ETH on Aave is 5.15%, allowing loopers to earn an additional 2.85% yield; weETH can be leveraged up to 14 times, resulting in a maximum annualized yield of about 45%.He believes that this essentially provides LST/LRT loopers with a "free lunch," while further deteriorating the user experience for aWETH holders and stablecoin borrowers.

The Arbitrum Security Committee announcement has taken emergency action to rescue 30,766 ETH stored at the Arbitrum One address, which is related to the KelpDAO vulnerability. With the assistance of law enforcement, the Security Committee identified the attacker and has always ensured that the safety and integrity of the Arbitrum community are maintained without affecting any Arbitrum users or applications.After extensive technical investigation and review, the Security Committee identified and executed a technical solution to transfer the funds to a secure location without impacting the state of any other chains or Arbitrum users. As of 11:26 PM Eastern Time on April 20, the funds have been successfully transferred to an intermediate frozen wallet. The address that originally held the funds can no longer access them, and only the Arbitrum governance body can take further action to transfer these funds, which will be coordinated with the relevant parties.

Charles Hoskinson, the founder of Cardano, stated that Bitcoin's quantum defense proposal BIP-361 has been mischaracterized as a soft fork, and is actually closer to a hard fork, and it cannot protect approximately 1.7 million early BTC generated before 2013, including about 1 million bitcoins attributed to Satoshi Nakamoto.He mentioned that the zero-knowledge proof recovery scheme in the proposal relies on BIP-39 mnemonic phrases, while early wallets used different key generation methods that cannot provide the required proof, thus the relevant assets may be permanently frozen under the current scheme. Reports also indicated that BIP-361 co-author Jameson Lopp described it as a rough concept for an emergency plan, rather than a final specification.

According to market news, Blockstream CEO Adam Back stated at the Paris Blockchain Week that he supports the optional advancement of Bitcoin's quantum resistance upgrade and opposes the proposal to forcibly freeze quantum-vulnerable addresses. He emphasized that "preparation is much safer than hasty responses in a crisis" and pointed out that the Bitcoin community has the coordination ability to respond quickly to urgent vulnerabilities.Previously, the BIP-361 proposal ("Post-Quantum Migration and Legacy Signature Sunset") put forward by developers Jameson Lopp and five others advocated for the gradual elimination of quantum-vulnerable addresses over five years, ultimately freezing coins that have not completed migration— including approximately 1.7 million Bitcoins held by Satoshi Nakamoto.

Bitcoin core developer Jameson Lopp stated that, compared to the potential quantum computing attacks that may arise in the future, he prefers to "freeze" about 5.6 million long-dormant BTC from the network rather than let them be acquired by attackers. These Bitcoins have not moved for over 10 years and may be permanently lost, valued at approximately $42 billion at current prices. If future breakthroughs in quantum computing lead to the decryption of old address private keys, this portion of assets could be re-transferred, triggering severe market fluctuations or even a crisis of confidence.Although the community recently proposed BIP-361, the proposal is still in its early stages and is not an officially promoted plan, but rather more like a contingency plan to address "extreme risks."

According to Jinshi reports, the White House stated that U.S. officials deny that the U.S. has agreed to unfreeze Iranian assets.

According to Cointelegraph, the joint law enforcement operation "Operation Atlantic" by the United States, the United Kingdom, and Canada was completed in March this year, led by the UK's National Crime Agency (NCA). Over $12 million in suspected fraud proceeds were frozen, and more than 20,000 victims were identified, with a total fraud amount exceeding $45 million.This operation focused on authorized phishing attacks—a scam technique that induces users to sign malicious authorizations, thereby allowing attackers to transfer tokens from the wallet. Binance participated by providing account screening and fraud intelligence support, but no funds were frozen from its platform.

On-chain detective ZachXBT stated on platform X that Circle has unfrozen two previously frozen hot wallets, marked as "500 Casino" and "Whale." Previously, due to the address being frozen, users were unable to withdraw from a certain centralized exchange to the affected business hot wallets.ZachXBT pointed out that, currently, the basic details of the case, such as the plaintiff, expert witnesses, and why Circle did not raise any objections, have not been disclosed. Earlier reports indicated that ZachXBT stated Circle, under public pressure, had unfrozen one of the 16 USDC wallets that were blacklisted.

The UK Foreign, Commonwealth & Development Office and the Home Office jointly announced sanctions against the illegal cryptocurrency market Xinbi and individuals related to Southeast Asian scam networks. According to data from blockchain analysis company Chainalysis, Xinbi processed over $19.9 billion in transactions from 2021 to 2025, involving illegal activities such as money laundering, unlicensed over-the-counter trading, and the sale of stolen personal data. The UK is the first country in the world to impose sanctions on Xinbi.The sanctions also involve the operator of the Cambodian "#8 Park" scam base, Legend Innovation Co., and its head Eang Soklim, who is believed to be holding up to 20,000 trafficked workers. Meanwhile, multiple properties in London have been frozen, with previously seized assets including an office building valued at £100 million, two luxury homes, and a helicopter. UK officials stated that this action aims to cut off the financial infrastructure of the scam networks and will promote broader international coordinated cooperation at the illegal finance summit in June this year.
