Cryptocurrency exchange OKX has warned customers against sending digital assets directly from rival trading platform MEXC, with founder Star Xu stating that linked funds may be frozen and relevant accounts investigated [1]. The warning follows an order issued by the US Treasury's Financial Crimes Enforcement Network (FinCEN) targeting MEXC [1], which [severed MEXC Global from the US financial system](https://basisdesk.news/news/fincen-severs-mexc-global-access-us-financial-system) over an alleged $16.7 billion in likely illicit fund movements between May 2021 and May 2026 [1]. Although the FinCEN prohibition applies strictly to US financial institutions and begins 30 days after Federal Register publication, OKX moved early to tighten compliance screening [1]. Xu stated that OKX treats FinCEN special measures with a level of vigilance comparable to financial sanctions [1]. Customers reported on social media that inbound transfers arriving directly from MEXC were flagged as originating from a "potentially high-risk address" [1]. The broader market backdrop saw mild consolidation at the time of writing, with $BTC trading at $74,250 and $ETH at $2,089. ## Retrenchment and Regulatory Exposure The regulatory pressure coincides with capital flight and market retrenchments for MEXC [1]. According to DeFiLlama data cited in reports, MEXC recorded $126.03 million in net outflows over a 24-hour period spanning the announcement, out of roughly $4.35 billion in tracked assets [1]. FinCEN's order alleged nearly $1.5 billion in exposure to Russian sanctions evasion, including direct interactions with sanctioned venues Garantex and Grinex, alongside $1.87 billion tied to Iran [1]. Furthermore, MEXC had already prepared exits from European jurisdictions, scheduling Dutch user terminations for Nov. 16 and French account wind-downs beginning Nov. 18 [1]. MEXC has rejected claims of operational impairment [1]. Chief Executive Officer Vugar Usi emphasized that the US regulatory action does not freeze or seize user balances, maintaining that trading, deposits, and withdrawals remain fully functional [1]. MEXC said it has initiated an independent compliance audit and plans to engage directly with FinCEN [1]. ## FAQ **Why did OKX issue a warning regarding MEXC transfers?** OKX warned users that deposits routed directly from MEXC could be flagged or frozen following a US FinCEN enforcement order targeting MEXC for alleged illicit financial activity. **Is OKX included in the US FinCEN order?** No. OKX is an entirely separate entity and is not named in FinCEN's order; the exchange is voluntarily applying strict risk controls. **What did FinCEN allege against MEXC?** FinCEN alleged that MEXC facilitated at least $16.7 billion in likely illicit transactions between May 2021 and May 2026, including transfers involving sanctioned Russian and Iranian entities. ## Sources 1.
