In brief

  • OKX founder Star Xu advised on X on November 7 pausing direct MEXC-to-OKX transfers.
  • FinCEN special measures against MEXC, with a 30-day transition period, preceded the warning, per Crypto Briefing.
  • TRC20 and ERC20 USDT deposits from MEXC were flagged and frozen, according to user reports.
  • Affected users will likely need to go through OKX's review process, per Crypto Briefing.

Frozen USDT deposits

Users began reporting that USDT deposits sent from MEXC to OKX were being flagged and frozen, Crypto Briefing said. Those are user reports (cited by the publication), and OKX hasn't confirmed them itself in the coverage.

The problems involved two common versions of the stablecoin, TRC20 and ERC20. TRC20 USDT moves on the Tron blockchain, while ERC20 USDT moves on Ethereum, so users on either route were hitting the same wall.

The network didn't seem to make a difference.

Concerns centered on high-risk addresses, which the publication described as wallets that OKX's systems linked to elevated compliance risk. Citing unnamed research findings, Crypto Briefing reported that OKX has rolled out enhanced risk controls on MEXC-linked funds. Those same findings described the controls as similar to the ones exchanges apply during financial sanctions.

A narrow advisory

Xu's advisory was tightly scoped. It didn't single out specific trading volumes, tokens or trading pairs, according to the report, and it focused on one thing: the direct MEXC-to-OKX transfer route.

News coverage began on November 7 and 8, 2026, and reports confirmed both the user complaints and the official advisory, per Crypto Briefing. For anyone who's already sent USDT and seen it frozen, the publication said they'll likely need to work through OKX's review process before those funds move again.

That's the practical takeaway for users right now.

What's still open

Crypto Briefing flagged two open questions. The first is whether OKX eases its controls once FinCEN's 30-day transition period ends. The second is whether rival exchanges adopt similar restrictions on MEXC-linked deposits, which would widen the impact well beyond a single transfer route between two platforms.

Neither question has an answer in the reporting so far, and the 30-day clock set by FinCEN is the date users will be watching.
