OKX has warned users that depositing cryptocurrency from addresses associated with high-risk sources may trigger extended anti-money laundering and risk reviews, potentially freezing access to funds for 15 days or longer. The warning came from OKX CEO Star Xu on September 2, 2026, after a user asked about betting platforms sending cryptocurrency directly to exchange wallets.
Xu identified Telegram guaranteed-transaction groups, Huiwang, and related variants as examples of high-risk funding channels. Huiwang is the pinyin name associated with Huione Guarantee, a Cambodia-based marketplace and payment network. According to reports cited by Flare.io, the Telegram marketplace processed more than $27 billion before regulators took action against it in 2025. Successor platforms including Tudou Guarantee later absorbed much of that activity.
During a risk review, OKX may restrict account functions and access to funds while compliance teams examine transaction histories. Xu said the review period can last 15 days or longer, but he did not describe 15 days as a fixed minimum or maximum. The length depends on the facts surrounding each account and transaction. Accounts confirmed to be linked to illegal activity could face permanent termination of services.
OKX had already flagged wallets linked to Huione Guarantee for compliance checks during the previous year. The exchange said it could freeze funds or deactivate accounts tied to confirmed network activity. FinCEN later cut the network off from the U.S. financial system in October 2025.
Xu did not disclose OKX's blockchain analytics providers or the specific risk score that triggers restrictions. He noted that blockchain screening tools attach risk labels to wallets connected with flagged services, but those labels do not prove ownership, criminal intent, or legal responsibility. Telegram escrow arrangements can also create additional source-of-funds questions because the sender may be an intermediary rather than the original buyer or seller.
The warning follows earlier criticism from legitimate users who reported account freezes caused by fraud screening. Xu apologized after one user reported that an account had remained frozen since June 21 despite extensive identity verification and proof-of-funds submissions. He acknowledged that false positives remain a continuing challenge for global compliance operations and said OKX has more than 600 employees working across its global compliance team.
