A survey by the Democratic Party of the U.S. Senate claims that the stablecoin USDT issued by Tether has become a major payment method for Iran. The survey shows that among over 800 sanctioned cryptocurrency wallets, about 84% primarily or exclusively use USDT.The U.S. Senate Permanent Subcommittee on Investigations had previously stated that its review of blockchain records, sanctions lists, and asset seizure notices found that the sanctioned wallets are mainly distributed across the Tron and Ethereum networks and have conducted USDT transactions.

According to the Economic Daily, major companies such as Apple, NVIDIA, AMD, Qualcomm, and MediaTek are racing towards AI and high-performance computing, recently increasing their orders for TSMC's 2-nanometer family capacity by 10% to 20%. As a result, TSMC is accelerating the expansion of its 2-nanometer family, with progress exceeding expectations. TSMC has consistently refrained from commenting on customer information and market rumors.The market originally estimated that TSMC's monthly capacity for the 2-nanometer family would be around 90,000 to 100,000 wafers by the end of this year, with expectations for continued double-digit growth to reach 110,000 to 140,000 wafers by 2027. Industry sources indicate that due to strong customer demand, the monthly capacity is expected to surge to 120,000 wafers by the end of this year, achieving the originally set 2027 target ahead of schedule. Sources say that in response to the demands from Apple and non-Apple customers, the speed and scale of new capacity for the 2-nanometer family are setting new records, far exceeding the ramp-up speed of the 3-nanometer family in its first year.TSMC's Senior Vice President and Co-COO, Wei Chen-Hao, stated at this year's North America Technology Forum that in response to strong demand from AI and other sectors, there will be five 2-nanometer fabs ramping up simultaneously for the first time this year, including two in Hsinchu and three in Kaohsiung; the wafer output in the first year of 2-nanometer will increase by 45% compared to the first year of 3-nanometer in 2023; the compound annual growth rate of 2-nanometer capacity from 2026 to 2028 will reach 70%. TSMC's 3-nanometer capacity in the Southern Taiwan Science Park is expected to reach nearly 180,000 wafers per month in the fourth quarter of this year, and three new 3-nanometer fabs are being established in Taiwan, Arizona in the United States, and Japan. The second fab in the United States is planned to begin mass production in the second half of 2027.

The "Whale" has set 10 major goals and updated its Bitcoin strategy on the X platform, stating that it has firmly aimed for $100,000 since the initial rebound of BTC from the bottom of $58,000. However, due to a failed attempt to judge the top along the way, it missed out on a significant portion of profits, and the current average entry position for its long positions is approximately $78,000.Regarding future operations, JasonLeo stated that if BTC falls below $79,000 again, it will begin to gradually close long positions; if it quickly rises to $100,000 in the short term, it will consider establishing some defensive short positions in the range of $98,000 to $105,000 to hedge against weekly-level pullback risks. If BTC stabilizes above $108,000 on the daily chart, the aforementioned short position logic will become invalid. If BTC does not directly surge but instead engages in thorough trading within the range of $80,000 to $100,000, it will consider taking defensive actions in the range of $115,000 to $125,000.

The cryptocurrency trading platform Bitget announced on its official X account that on September 24, 2026, at 18:31 (UTC), its security system detected unauthorized transfers from a small number of hot wallets. The security team has immediately initiated an emergency response procedure and started a comprehensive investigation.Bitget stated that, based on current assessments, approximately $351.6 million in assets are affected. Cold wallets and the vast majority of assets on the platform remain secure and unaffected, and user funds are still protected. The incident falls within the coverage of the user protection fund, which currently holds over $464 million.Bitget mentioned that customer account balances remain accurate, and deposits and transactions continue to operate normally. As a precautionary measure, withdrawals have been temporarily suspended to allow the team to complete a thorough security review. The company has identified and flagged the relevant transfer addresses, formally contacted law enforcement agencies and on-chain security partners, and will restore withdrawals as soon as safety is confirmed, providing subsequent updates through official channels while refraining from speculating on the attack path during the investigation.

B.AI announced a major upgrade to its Responses API, which is now fully compatible with upstream standard protocols. Existing models on the platform can be uniformly called through the /v1/responses interface as long as they support the Responses API.At the same time, when B.AI adds new models from integrated vendors in the future, developers will not need additional configuration to automatically and seamlessly integrate them into the Codex client. In this upgrade, the official API full set group adds support for MiMo, Qwen, and Hunyuan series models, while the Mix and OL Station optional service provider group adds support for OpenAI, Gemini, and Grok series models.Developers only need to complete the minimal configuration of the API Key and Base URL to integrate the capabilities of various models into their daily workflows.

According to Cointelegraph, the European Banking Authority (EBA), the European Insurance and Occupational Pensions Authority (EIOPA), and the European Securities and Markets Authority (ESMA) stated in a joint risk update that advancements in quantum computing could undermine the cryptographic systems that secure blockchain transactions, communications, and databases.Google Quantum AI researchers estimated in March that the number of physical quantum bits required to break the cryptographic techniques used by many cryptocurrencies is about 20 times less than previously estimated. There currently exists no computer capable of executing such an attack.Bitcoin developer Jameson Lopp and others proposed in February to gradually phase out the current signature scheme and to restrict the usage of untransferred funds five years after the proposal is activated; this proposal has not yet been adopted. The Ethereum Foundation plans to enable Ethereum's execution, consensus, and data layers to be resistant to quantum attacks by December 2029.

The six major banks in Canada announced a joint exploration of a tokenized Canadian dollar deposit system, aimed at accelerating the transfer of funds between financial institutions and ultimately connecting with other digital asset programs. TD Bank announced on Tuesday that the Bank of Montreal, Canadian Imperial Bank of Commerce, National Bank of Canada, Royal Bank of Canada, Scotiabank, and Toronto-Dominion Bank Group have jointly formed this joint venture project, with the possibility of more banks joining in the future.The first phase of the project will focus on promoting the transfer of tokenized deposits among participating banks. The parties stated in a joint statement that the first phase aims to enable efficient circulation of tokenized deposits among Canadian financial institutions, with the long-term goal of connecting with other emerging digital asset programs. Tokenized deposits are digital representations of funds and assets already held by banks, differing from independent stablecoins issued by crypto companies; this system allows for 24/7 programmable payments within a regulated banking system.Canada's move comes as global banks compete to put deposits on the blockchain. In the United States, regional banks are building a shared tokenized deposit network, while JPMorgan, Citigroup, and Wells Fargo have also launched their own institutional products. Recently, Swift has begun testing cross-border payments for tokenized deposits. Additionally, the Bank of Canada, Royal Bank of Canada, and Toronto-Dominion Bank completed the Project Samara test in March this year, issuing, trading, and settling CAD 100 million (approximately USD 71 million) bonds on a distributed ledger; in May, Shopify and National Bank of Canada also supported the launch of a regulated digital Canadian dollar.
