Cryptocurrency exchange OKX has announced a significant tightening of its compliance procedures, placing incoming transactions linked to gambling and the activities of shadow guarantee services under special scrutiny. This decision is not a targeted measure but part of a systemic strategy to reduce regulatory risks, which have recently become the industry's biggest headache.
New Rules of the Game: 15 Days for Review
Under the updated policy, transfers of funds from addresses classified as high-risk will automatically trigger an in-depth anti-money laundering (AML) review. Such a procedure may last 15 days or more. During the investigation, the exchange reserves the right to restrict account functionality and freeze access to funds. If the review confirms the illegal origin of the capital, the user risks losing complete control over their account.
OKX CEO Star Xu, in his statement on social network X (September 2), directly pointed to the sources of heightened danger. Transfers through so-called "guaranteed" escrow services in Telegram groups, as well as transactions passing through the Huione network (Huione Guarantee), came under special scrutiny. Notably, before regulators intervened in 2025, this Telegram marketplace, by my estimates, managed to process transactions exceeding $27 billion, effectively becoming the largest shadow settlement infrastructure.
The Domino Effect: From Huione to Tudou
The wave of blockades by U.S. authorities did not go unnoticed. After the U.S. Treasury's FinCEN division banned Huione Guarantee from accessing the U.S. financial system in October 2025, its volumes rapidly shifted to similar platforms, particularly Tudou Guarantee. OKX, which had already begun tracking wallets linked to Huione last year, is now forced to expand its monitoring perimeter to cover all such structures.
"Funds received through channels such as guarantee transactions in Telegram groups, Huione, and similar services may carry elevated risks," emphasized Star Xu.
The Cost of Error and the Cost of Compliance
This tightening is a direct response to unprecedented pressure from regulators. According to data from analysts at CertiK, AML-related risks have finally displaced securities disputes from the top spot as the main source of regulatory pressure on the crypto market. Over the past year alone, OKX has paid more than $500 million in fines for AML violations — a figure that forces a reassessment of risk-management approaches.
However, there is another side to the coin. Xu admitted that the system is not perfect and sometimes mistakenly flags transfers from legitimate users. A wave of criticism hit the exchange back in July 2025, when some accounts were blocked due to false positives from anti-fraud systems.
Whether the new rule with its 15-day review can effectively cut off illegal flows without harming legitimate depositors will become clear in the near future. In my understanding, the balance between speed and security is the key challenge for all centralized platforms, and OKX is currently operating on the principle of "better safe than sorry," which in the current climate looks like the only viable survival strategy.
