first_img Cross-chain trading platform Relay API exposes pending transactions, which will compensate approximately $312,000

Co-founder and Chief Operating Officer of the cross-chain trading platform Relay, Jason Maier, stated that the team discovered an issue with the Relay API over the weekend, which exposed pending transaction information before trade execution. MEV seekers exploited the pending routing status to infer on-chain paths and front-run trades before order execution, resulting in worse execution prices for users trading through Relay.This activity occurred from September 12 to September 26, primarily concentrated from September 23 to 26. Seekers profited approximately $136,000 from this, affecting around 5,600 users, with a median impact of $11.88. Relay will pay a $50,000 bounty to Outputlayer for reporting the issue and will automatically compensate affected users without the need for applications; funds will be directly sent to wallets, with a total compensation amount of approximately $312,000.Jason Maier stated that MEV can arise through public mempool exposure, order detail inference, malicious participation in auctions, or data gaps between service providers, and protecting a single link in the transaction path is not sufficient. He mentioned that the team will continue to enhance the execution quality and privacy of the entire transaction path and called on security researchers to report vulnerabilities when discovered.

first_img TSMC plans to build a second campus in Texas, with an estimated investment exceeding Arizona

According to the Economic Daily, citing sources from the semiconductor equipment industry, TSMC plans to expand its manufacturing presence in the United States. Following Arizona, it is set to initiate plans for a second park in the U.S., with a high likelihood of establishing six advanced wafer fabs in Dallas, Texas. Reports indicate that if the second park is launched, the total investment is expected to exceed the $265 billion in Arizona, linking Arizona's wafer manufacturing with Texas's advanced ecosystem. As of September 28, the reporter has not received a response from TSMC; supply chain operators stated that the owner has not yet notified preparations, and the board has not yet made a decision.The total investment in TSMC's wafer fab in Phoenix, Arizona, has now increased to $265 billion, with plans including six wafer fabs, two advanced packaging plants, and a research and development center. Reports suggest that TSMC's considerations for increasing its overseas presence include proximity to customers, diversification of geopolitical risks, and overcoming resource limitations such as land, water, and electricity in Taiwan. U.S. customers accounted for approximately 75.64% of TSMC's revenue in the first half of 2026.There are widespread rumors in the industry that TSMC is responding to demands from customers like NVIDIA, Intel, AMD, and Apple for local production in the U.S., while facing pressure from the U.S. government, which has threatened that chip manufacturers must relocate back to the U.S. or face tariffs of up to 200%. Dallas and North Texas are known as the "Silicon Prairie," with local factories established by Texas Instruments, Coherent, Samsung, and Tesla. Reports indicate that the Arizona facility still faces challenges such as water shortages, power shortages, and labor shortages, while Texas offers talent, lower tax burdens, and stable electricity, leading supply chain operators to believe that site evaluations are nearing completion.

first_img MEXC user: API not revoked after account was hacked, approximately 340,000 USD was transferred away

A MEXC user posted on X that their account was compromised after someone reset the security items. MEXC has confirmed the account was hacked, frozen the account, and assisted in recovery, but did not revoke the API left by the attacker. From 04:12 to 04:25 on September 27, 2026 (Beijing time), the account transferred out 322,110 USDT and 9,133,999 ONE, totaling approximately $340,000, about 27 minutes after the 24-hour transfer limit was lifted.The user stated that at 03:10 on September 25, they received a reset security item email that was not submitted by them, and about 10 minutes later, the request was approved. Subsequently, the account was logged in from an IP in Jakarta, Indonesia, bound to Google verification, and at 05:05, an API was created, approximately 83 seconds after logging in. At 10:55 that day, MEXC froze the account after a risk review and reverted to the original email. Customer service responded in writing that the review materials met the requirements, so the binding change was approved, and after the risk review, the account was urgently frozen and reverted to the initial email. The user changed their password and Google verification on September 26 but stated that the API was not revoked, and there were no related records in the security operation history.The user also claimed that there were no new login records in the login history when the assets were transferred out. They have submitted a formal claim to MEXC and attempted to report to the police, with the ticket number M2026092712031, requesting the platform to preserve logs, provide a written explanation of the review and API situation, and return the aforementioned assets. MEXC customer service stated that it is currently unable to confirm whether these transfers were initiated via APP, WEB, or API, and the issue has been forwarded to the relevant department.
