According to TechFlow, OKX founder Star Xu responded to the QuantMatter incident on social media, saying, "This account has nothing in common with other cases, and the time is completely different. We are still investigating. What is certain is that there are complete logs showing that the withdrawal was initiated by the web page, and the withdrawal request entered the complete GA and email verification code."

Earlier news said that QuantMatter, a Singaporean market maker, had its 11.6 million U.S. dollars stored in OKX stolen, and claimed to have offline Google verification.
