OKX Warns on MEXC Transfers as Whale Withdraws $13.4M
OKX has tightened checks on MEXC-linked funds as users report deposit holds. A whale moved about 13.4 million USDT into a multisignature wallet.
Key Notes
- OKX founder Star Xu warned users to avoid direct transfers from MEXC while enhanced checks are in place.
- Seven transfers from a wallet labeled MEXC 16 sent about 13.42 million USDT to a Safe smart account on November 7.
- Reports involving other exchanges remain user accounts rather than evidence of a coordinated industry-wide ban.
OKX is warning users against direct transfers from MEXC as heightened compliance checks leave some customers’ deposits on hold. The scrutiny comes as Onchain Lens reported a large holder moving about 13.4 million USDT from MEXC into a multisignature wallet.
The developments show how the US Treasury’s action against MEXC is affecting customers’ ability to move assets between platforms, even before the federal transfer prohibition takes effect.
OKX Tightens Checks Ahead of the Deadline
OKX founder and CEO Star Xu warned on X on November 7 that customers should temporarily avoid sending funds directly from MEXC to OKX. He said the exchange was applying cautious risk-management standards similar to those used for financial sanctions.
Under those controls, funds associated with affected platforms may be frozen for review, while linked accounts may face further investigation, Xu said. He apologized to affected users and acknowledged that innocent customers could be caught up in the restrictions.
Xu said OKX had significantly strengthened its controls ahead of the transition period rather than waiting until the deadline. His statement did not give a release timetable for held deposits or establish that every MEXC-linked transfer would be rejected.
A Whale Moves USDT to a Multisignature Wallet
In a November 8 post, Onchain Lens linked the whale’s withdrawal to concerns about account freezes at centralized exchanges.
CoinScreamer’s review of the linked wallet record found seven incoming USDT transfers on November 7 from an Ethereum address labeled “MEXC 16.” Together, they totaled approximately 13.42 million USDT. Etherscan identifies the receiving contract as a Safe smart account.
The transfers support the reported amount and destination. They do not independently establish the holder’s motive or make the funds’ previous exchange connection disappear. A multisignature wallet describes how transactions are authorized, not whether a receiving exchange will accept its funds.
Reports Extend Beyond OKX
RootData’s summary of community reports also described delayed crediting, risk reviews and refund-review processes involving MEXC transfers to Binance and Gate.
Those accounts do not establish a coordinated, exchange-wide ban. The number of affected users, the full scope of restrictions and the eventual handling of individual deposits remain unclear.
The US Order Has a Separate Start Date
The November 6 FinCEN order prohibits covered US financial institutions from sending funds to or receiving funds from MEXC Global, including cryptocurrency. It takes effect 30 days after Federal Register publication, rather than immediately upon the announcement.
As CoinScreamer’s earlier coverage explained, Treasury cited at least $16 billion in illicit transactions connected to sanctions evasion and cybercrime. The order’s transfer prohibition is distinct from an immediate, worldwide freeze of all customer balances.
MEXC, meanwhile, says it is operating normally and user assets remain secure. Its statement announced an independent review of anti-money-laundering and sanctions controls, as detailed in our report on the MEXC response.
That assurance addresses operations at MEXC. Whether another platform credits an incoming deposit remains a separate decision under that platform’s compliance controls.
