AI company Anthropic announced that starting from April 4 at 15:00 Eastern Time, it will prohibit access to third-party tools through the Claude subscription service, including the open-source project OpenClaw. The new regulations require that related features can only be used through additional packages or billed on a pay-as-you-go basis via API.This adjustment means that many developers and teams relying on OpenClaw to build automated workflows will shift from a fixed subscription cost model to an unlimited pay-as-you-go system, significantly increasing overall usage costs. Some developers have indicated that the original usage cost of about $20/month could soar to hundreds or even thousands of dollars.The market generally believes that this move is related to OpenClaw founder Peter Steinberger's recent joining of OpenAI. Meanwhile, Anthropic is accelerating the promotion of its own tool ecosystem, including native integration solutions for Claude, to replace third-party toolchains.It is worth noting that Anthropic has previously tightened third-party access through technical restrictions, updates to service terms, and feature replacements. This policy is seen as a "final blockade" and will be extended to more tools.Industry analysis points out that this event reflects an intensifying trend of "ecosystem tightening" in AI platforms, with leading companies strengthening control through vertical integration. At the same time, the developer ecosystem faces rising cost uncertainties and platform dependency risks, which may further drive some users toward more open alternatives.

According to Decrypt, the U.S. Attorney's Office for the District of Connecticut announced that it has recovered and seized over $600,000 in cryptocurrency after a Ledger hardware wallet user fell victim to a phishing scam, being lured into performing a so-called security check by a letter impersonating "Ledger Security and Compliance," resulting in approximately $234,000 in crypto assets being stolen.The FBI and state police tracked the flow of funds, successfully seizing about $600,000 in USDT and filing a civil forfeiture lawsuit, alleging that the source of the funds involved wire fraud and money laundering. It is reported that this is one of a series of phishing incidents targeting hardware wallet users, where scammers used physical mail letters featuring company logos, holograms, and QR codes to enhance the credibility of the fraud. Similar incidents have affected companies like Ledger and Trezor, accompanied by data breaches and vulnerabilities in third-party services, leading to ongoing phishing attacks.

According to The Block, investment firm Benchmark has initiated coverage on Securitize for the first time, giving it a buy rating with a target price of $16.

Currently, the company holds about 70% of the U.S. tokenization market and has partnered with leading asset management firms such as BlackRock. Securitize plans to go public on Nasdaq through a merger with Cantor Equity Partners II, with the stock ticker SECZ.

Resolv Labs co-founder Ivan released an update on the protocol security incident and subsequent recovery progress. It is reported that whitelisted USR users can redeem first, mainly because their wallets have been verified, and the Resolv team can manually process within 24 hours to control risks. Currently, 98% of related redemptions have been completed.For non-whitelisted USR holders before the vulnerability occurred, Resolv promises to redeem at a 1:1 ratio as well, but the relevant redemption technical plan is still being finalized.Regarding whether there are internal personnel involved, Ivan stated that no evidence of internal participation has been found so far. For USR holders, LPs, and RLP holders after the vulnerability occurred, the subsequent processing involves legal, technical, and ecological coordination among multiple parties, and there is no single solution at this time. A complete recovery plan does not yet have a clear timetable, and the follow-up will be completed as soon as possible while ensuring prudent progress.Previously, the Resolve attacker used 200,000 USDC to mint 80 million USR.

It also emphasizes a "platform-agnostic" architecture to maintain system openness and interoperability. Furthermore, the report highlights the importance of governance and risk control, stating that the application of blockchain in public systems requires accompanying privacy protection, regulatory frameworks, and audit mechanisms to prevent data misuse and smart contract risks. Overall, blockchain is extending from financial scenarios to public governance infrastructure, becoming one of the important technological options for digital transformation in various countries.

Resolv Labs issued an update regarding a security incident, stating that a malicious attacker illegally accessed Resolv's infrastructure through a stolen private key and minted approximately $80 million worth of uncollateralized USR. The relevant smart contracts have been quickly paused, and approximately 9 million USR held by the attacker have been destroyed to mitigate potential impact.Currently, the protocol holds about $141 million in assets, with the confirmed actual impact being only about $500,000 in redemptions processed before the pause. The current USR supply consists of approximately 102 million tokens before the incident and about 71 million newly minted illegal tokens. As the first step towards recovery, Resolv plans to allow redemptions of pre-incident USR starting from March 23, 2026, for whitelisted users. Affected users should coordinate directly with RDAL through official channels.The announcement stated that the incident stemmed from unauthorized actions by a third party, including targeted infrastructure attacks. Resolv's underlying collateral has not been directly compromised. The team is tracking and attempting to control the illegally minted USR and other affected assets, coordinating with partners and counterparties, and working with law enforcement and on-chain analysis companies to trace the responsible parties. Resolv strongly advises against trading USR or related Resolv tokens during the implementation of recovery measures, as user trading behavior after the incident may affect the recovery process.

Recently, a first-instance verdict was announced in a case of concealing and hiding criminal proceeds, which was prosecuted by the People's Procuratorate of Yuetang District, Xiangtan City, Hunan Province, China. A new type of money laundering chain, disguised as a Maotai liquor transaction and using virtual currency as a channel, was completely dismantled, involving an amount of over 6.84 million yuan, with all 8 defendants sentenced. The gang had clear divisions of labor and strong concealment.Chen connected with upstream sources through overseas encrypted communication software, received telecom fraud proceeds, and contacted "U merchants" to complete the exchange and circulation of virtual currency; Xie was responsible for providing tools for the crime and keeping track of financial details; Huang used Maotai liquor trading as a cover to disguise the trajectory of the transfer of criminal proceeds with real transaction shells; the remaining members assisted with fund settlement and information transmission. The gang used fake Maotai liquor transactions as the "cleaning" stage, disguising overseas fraud proceeds as legitimate business income, converting them into virtual currency to return to upstream, and taking an illegal commission of 8% for each "cleaning."In December 2023, with a report from a victim, this black and gray industrial chain hidden under the guise of liquor trading surfaced. After the incident, the People's Procuratorate of Yuetang District intervened in the investigation early, guiding the public security organs to sort through nearly 20 million yuan in fund flows and massive electronic data, achieving a full-chain crackdown and comprehensive evidence collection. The court ultimately sentenced Xie and 7 other principal and accomplice offenders to fixed-term imprisonment ranging from 2 to 6 years for the crime of concealing and hiding criminal proceeds; the relatively minor offender Liang was sentenced to 1 year in prison with 1 year of probation.
