OKX Warns MEXC Users of Deposit Freezes Ahead of FinCEN Cutoff

Users holding balances on MEXC can no longer wire them straight into an OKX account without risking a hold; deposits traced to MEXC addresses are flagged for manual review rather than credited instantly. Traders who relied on a direct MEXC-to-OKX corridor for withdrawals or arbitrage now need a third exchange or a personal wallet as a buffer. OKX's compliance desk gains the power to freeze first and ask questions later, while MEXC loses a convenient off-ramp its customers counted on.

Usi's public defense of MEXC's solvency sits uneasily next to Xu's decision to treat transfers from the same exchange with sanctions-level caution; the two messages pull depositors in opposite directions. The episode also shows how a single FinCEN designation can ripple through transfers between exchanges with no formal relationship to each other, giving a U.S. regulatory tool outsized reach over an offshore platform's day-to-day liquidity and the counterparties willing to touch its funds.

The next marker is whether FinCEN formally finalizes or withdraws the special measure it has signaled against MEXC, and whether OKX's current manual-review stance hardens into an outright block once that cutoff arrives. A finalized designation would likely force other exchanges to follow OKX's lead on MEXC-linked deposits; a reversal or delay would let Usi's solvency defense stand unchallenged and ease the pressure on users still holding funds there.
