According to official disclosures from Coinbase, it has collaborated with Microsoft and several institutions to combat the AI-driven cybercrime platform EvilTokens. This platform offers "phishing as a service" through Telegram bots, utilizing AI to analyze trust relationships and payment permissions in compromised email accounts, and bypassing multi-factor authentication through Microsoft's device code login process.The Coinbase global intelligence team tracked that between October 2025 and June 2026, EvilTokens generated approximately $1.1 million in revenue through four Tron addresses, involving over 1,000 deposits from more than 700 different addresses. The related evidence supported Microsoft's civil lawsuit, ultimately leading to the seizure of 50 websites and the deactivation of over 175 associated domain names. The Metropolitan Police Service of the United Kingdom arrested the relevant operators and seized digital devices on September 11. Coinbase stated that this incident did not result in the leakage of Coinbase accounts or credentials, but some customers were manipulated into transferring cryptocurrency to the scammers' addresses through phishing emails.

According to CoinDesk, Taylor Lindman, the Chief Legal Counsel of the U.S. Securities and Exchange Commission (SEC) Crypto Working Group, stated at the CoinDesk Policy & Regulation event held in Washington that the SEC is advancing rules for the custody of crypto assets. The relevant proposal has been submitted to the Office of Management and Budget (OMB) for review, covering investment companies and broker-dealers. She indicated that the rule aims to inform the market about how to hold non-securities crypto assets within broker-dealers without special registration and clarifies that investment advisors can store client assets in institutions such as state-chartered trusts.Once the proposal passes the review by the Office of Management and Budget, the SEC will formally present it and seek feedback from the industry and the public. Lindman also mentioned that the SEC will issue an employee statement in December 2025 as a transitional arrangement, guiding broker-dealers on handling crypto custody matters before the rules are implemented, and will allow investment advisors to store client assets in state-chartered trusts as qualified crypto custodians starting in September 2025.Lindman described the SEC's recent work as "laying the groundwork," including previously proposed rules allowing crypto issuance and exemptions for tokenized securities. She stated that the SEC is working to ensure that existing securities intermediaries and market participants can confidently use blockchain to hold and trade crypto assets. Previously, the SEC's attempts at custody rules under Gary Gensler in 2023 were abandoned, and a leadership supportive of crypto was appointed after the Trump administration took office.

According to CoinDesk, the European Central Bank (ECB) and the central banks of EU member states wish to prohibit crypto platforms from providing indirect yields on stablecoins through lending, staking, and other products. The European System of Central Banks (ESCB) stated in response to the European Commission's consultation on the review of the Markets in Crypto-Assets Regulation (MiCA) that electronic money should be used for payments rather than savings, continuing to support the prohibition of crypto asset service providers (CASP) from paying rewards for stablecoins, and that the ban should not be limited to services already regulated by MiCA but should also cover unregulated activities such as crypto lending, borrowing, and staking.Central banks believe that allowing indirect yields could blur the lines between electronic money and bank deposits, distorting the fair competitive environment of the EU financial system. The ESCB stated that maintaining and, when necessary, strengthening this ban, while covering both direct and indirect forms of rewards, should be a clear legislative priority. This position also echoes the controversy in the U.S. surrounding the Clarity Act, where eight U.S. banking groups urged senators to tighten the bill's restrictions on stablecoin rewards, which ultimately failed in a procedural vote of 49 to 50.In addition, central banks also proposed to eliminate the MiCA requirement for stablecoin issuers to hold part of their reserves in the form of bank deposits, replacing it with liquidity rules based on the liquidity of reserve assets. Currently, stablecoin issuers must keep at least 30% of their reserves in credit institutions, and this percentage rises to 60% for those classified as significant stablecoins. The ESCB suggested that significant stablecoins must allocate at least 40% of their reserves to assets maturing within one day and 60% to assets maturing within five working days, while the corresponding thresholds for non-significant stablecoins are 20% and 30%.

The People's Bank of China today reiterated in its financial education campaign that virtual currencies such as Bitcoin, Ethereum, and Tether do not have legal tender status and cannot be used for currency circulation; conducting virtual currency-related businesses within the country is considered illegal financial activity and is strictly prohibited.The People's Bank of China stated that without the consent of relevant authorities, domestic entities and their controlled overseas entities are not allowed to issue virtual currencies abroad, and no units or individuals, whether domestic or foreign, are permitted to issue stablecoins pegged to the Renminbi abroad. The People's Bank reminds the public not to participate in virtual currency issuance, trading, investment, or mining activities, to be wary of high-yield investment scams, and to avoid renting out bank cards, payment accounts, or participating in virtual currencies.In addition, the People's Bank advises caution against virtual currency investment products and trading platforms that claim "guaranteed profits" or "high interest"; not to participate in virtual currency issuance, trading, investment, or "mining" activities; not to join communities promoting virtual currency activities, not to click on links containing overseas virtual currency trading platforms, or download related apps; not to lend or rent out bank cards or payment accounts, not to buy or sell virtual currencies "on behalf of others" as instructed, and not to act as "drivers," "currency dealers," or "U merchants"; and to report any clues related to virtual currency business activities to the relevant regulatory authorities in a timely manner.

According to CoinDesk, Daren Guo, founder of Reap, a Hong Kong fintech platform and Visa partner, stated that Reap plans to add a Mexican peso stablecoin to its card, cross-border payment, and fund management products, and is exploring stablecoins for the Hong Kong dollar, euro, Korean won, and Japanese yen to support around-the-clock on-chain foreign exchange settlements and reduce cross-border costs.Reap is a major issuing member of Visa in Hong Kong and Mexico (VPIM), owned by Kraken's parent company Payward, and can issue cards on its own BIN, claiming to support partners in over 100 markets. Guo noted that while public blockchains continue to operate, global foreign exchange still relies on bank operating hours, correspondent banks, and settlements that can take several days. Transfer fees for some currency corridors in emerging and cross-border markets can reach 5% to 7%, while nearly 99% of current stablecoin payments are denominated in US dollars.The company is integrating stablecoin settlements into a broader product system that includes cards, cross-border payments, fund management, and compliance risk control. Reap stated that in the first half of 2026, card and payment volumes grew by 33% year-on-year, with revenue and transaction volume expected to double in 2025. Stephen Karpin, President of Visa Asia Pacific, stated that blockchain settlement should not be viewed as a replacement for traditional payment systems, but rather as a complementary relationship, with opportunities to reduce friction and maintain interoperability with the broader financial system.

According to a Reuters report, the European Central Bank and the central banks of EU member states expressed opposition to the requirement that major stablecoin issuers hold at least 60% of their reserve assets in the form of bank deposits during the consultation on the regulatory framework for crypto assets, MiCA. The reason is that this could expose banks to fluctuations in the stablecoin market and undermine the stability of deposits.The central bank system suggested changing the regulation to require that a certain proportion of reserve assets must be short-term assets maturing within 1 to 5 working days. At the same time, the central bank pointed out that despite MiCA being in effect, non-compliant crypto companies can still reach EU customers, and regulatory enforcement faces "significant challenges," posing risks to investor protection.
