OKX founder Star Xu advises users to avoid direct MEXC transfers

OKX founder Star Xu has a simple request for anyone holding funds on MEXC: please do not send them straight to OKX right now.

On November 7, 2026, Xu posted on X advising users to temporarily hold off on direct transfers from MEXC to OKX. The warning followed special measures taken by FinCEN, the US Treasury’s financial crimes unit, against MEXC.

What OKX is doing, and why it is moving early

According to the research findings, OKX has rolled out enhanced risk controls on MEXC-linked funds. They are described as similar to the controls exchanges apply during financial sanctions.

The timing is notable. FinCEN set a 30-day transition period for its measures against MEXC.

OKX chose not to use that runway. Instead, the exchange moved immediately, acting ahead of the window rather than waiting for it to close.

Users report frozen USDT deposits

The advisory did not arrive in a vacuum. Users began reporting that USDT deposits sent from MEXC to OKX were being flagged and frozen.

The reported problems involved two common versions of the stablecoin: TRC20 and ERC20. These labels refer to the networks the tokens travel on. TRC20 USDT moves on the Tron blockchain, while ERC20 USDT moves on Ethereum.

The network did not seem to make a difference. Concerns centered on high-risk addresses, meaning wallets that OKX’s systems linked to elevated compliance risk.

News coverage of the situation began on November 7 and 8, 2026. Reports confirmed both the user complaints and the official advisory.

The advisory did not single out specific trading volumes, tokens, or trading pairs. The guidance focused squarely on the transfer route itself: MEXC to OKX, directly.

The bigger picture on exchange compliance

The research findings frame this as part of a growing emphasis on compliance as regulatory pressure intensifies. Exchanges are increasingly reacting quickly to regulatory shifts instead of waiting for deadlines.

What this means for traders and the market

For users, the practical takeaway is straightforward. Anyone planning to move funds from MEXC to OKX faces a real chance of having those deposits flagged.

Xu’s advice suggests avoiding the direct route for now. Users who already sent USDT and saw it frozen will likely need to work through OKX’s review process.

The research findings point out that liquidity and fund movement may shift as users adjust to stricter practices across exchanges.

According to the research findings, continued enforcement from US regulators could bring heightened scrutiny on compliance issues across the broader crypto market.

For now, the things to watch are concrete. One is whether OKX eases its controls once FinCEN’s 30-day transition period ends. Another is whether rival exchanges adopt similar restrictions on MEXC-linked deposits.

The episode shows how quickly a regulatory action against one platform can reach users of another. A FinCEN measure aimed at MEXC ended up freezing deposits at OKX, and prompted its founder to ask customers to stay away.
