Weeks after the UK imposed sanctions on the exchange, HTX is still open for business — and according to blockchain intelligence firm TRM Labs, it has been cycling through hot wallets across multiple blockchains at a pace that leaves traditional compliance screening tools struggling to keep up. The firm’s findings have thrust the HTX UK sanctions case back into the spotlight, raising serious questions about whether static address-based blacklists are fit for purpose when dealing with well-resourced crypto exchanges.
Summary
Key takeaways
- The UK sanctioned Huobi Global S.A., the parent entity of HTX, on May 26, 2026, over suspected ties to Russian sanctions evasion.
- HTX is suspected by the UK government of channeling over $1.5 billion to the Kremlin via the A7 network.
- TRM Labs reports HTX has been rotating hot wallets across TRON, Ethereum, BNB Smart Chain, and Solana, retiring addresses every few hours.
- HTX says the wallet activity reflects routine, security-driven operations and rejects any other characterization.
- Neither OFAC nor the EU has sanctioned HTX, limiting current freeze obligations to UK-regulated firms only.
UK sanctions target Huobi Global S.A. — and by extension, HTX
The UK Foreign, Commonwealth and Development Office designated Huobi Global S.A. on May 26, 2026, marking the first time Britain applied sanctions of that scale to a crypto exchange. The designation came as part of a broader package targeting financial and crypto networks accused of helping Russia circumvent international restrictions.
At the center of the UK’s rationale: suspicions that HTX, described in the official listing as a “major global cryptocurrency exchange,” had channeled more than $1.5 billion to the Kremlin through the so-called A7 network. British authorities said the exchange provided financial services connected to Russia-linked entities, triggering an asset freeze and restrictions covering payment processing, correspondent banking, trust services, and internet services.
HTX pushed back immediately. The exchange argued that Huobi Global S.A. was legally distinct from the operating platform itself, and that user funds were safe with global operations unaffected. The UK’s Office of Financial Sanctions Implementation, known as OFSI, quickly clarified its position: it considers HTX subject to UK financial sanctions because of its ownership by Huobi Global S.A. The branding separation argument, in OFSI’s view, did not hold.
The sanctions also compounded earlier regulatory pressure. In February 2026, the UK’s Financial Conduct Authority launched legal proceedings against HTX over alleged unlawful financial promotions to UK consumers, with the High Court issuing further orders connected to that case as recently as June.
HTX’s wallet rotation complicates sanctions compliance
Despite the designation, HTX has continued operating under the same brand — and TRM Labs says it has simultaneously been rebuilding its on-chain infrastructure in ways that make sanctions enforcement significantly harder.
Scope and frequency of wallet rotations
In a report published on July 22, TRM Labs documented that HTX has been rapidly rotating hot wallets and funding addresses across TRON, Ethereum, BNB Smart Chain, and Solana. The pattern is consistent and fast: individual addresses can remain active for only a few hours before HTX moves activity to fresh wallets, effectively retiring each address before it makes it onto any static compliance list.
“HTX is changing its wallets every few hours to stay a step ahead of screening built on static lists,” said Ari Redbord, global head of policy at TRM Labs.
The result, as TRM describes it, is that a block list built from known HTX addresses becomes stale almost immediately. Much of the exchange’s activity since the May designation has flowed through addresses that no existing list has ever flagged.
Impact on address-list screening
This is where the story gets strategically important for the compliance industry. Traditional sanctions screening depends on maintaining accurate lists of wallet addresses tied to designated entities. When an exchange rotates those addresses every few hours across four major blockchains, the static model breaks down completely.
TRM Labs argues that the only effective counter is behavior-based attribution — a method that tracks how wallets interact on-chain and links newly created addresses to known entities based on transaction patterns, rather than waiting for compliance teams to manually add each new address. According to TRM, such systems can identify a fresh HTX wallet as it comes online, updating attribution nearly as fast as the exchange rotates.
The implication for compliance professionals is significant: address-list screening alone is no longer sufficient when dealing with a sanctioned entity that actively cycles its infrastructure. The tools industry uses today were largely built for a slower-moving threat environment.
Comparison to other sanctioned entities’ tactics
TRM Labs frames HTX’s approach within a broader pattern it has tracked across sanctioned, well-resourced entities. The firm drew a direct comparison to Russian exchange Garantex, which was taken down in March 2025. After that action, Garantex’s operators reportedly spun up a successor exchange called Grinex and migrated liquidity through the ruble-pegged A7A5 stablecoin. HTX, by contrast, kept its brand intact and adapted at the wallet infrastructure level rather than relaunching under a new name — a different but equally evasive playbook, according to TRM.
Regulatory and compliance perspectives on HTX’s wallet activities
HTX’s statement on wallet rotations
HTX has been consistent and blunt in its response. A spokesperson told both Decrypt and The Block: “The technical activities referenced in TRM’s report reflect routine, security-driven platform operations common across the industry. We categorically reject any characterization implying otherwise and have no further comment.”
The exchange had separately stated in May that regulatory compliance remains a “top priority” and that it proactively monitors and adheres to regulatory frameworks in all jurisdictions where it operates, including the UK.
Status of HTX under international sanctions regimes
One of the most consequential facts in TRM Labs’ report is also one of the least discussed: OFAC, the U.S. Treasury’s sanctions enforcement arm, and the EU have not designated HTX. That gap matters enormously. Freeze obligations and compliance requirements currently apply only to UK-regulated firms in relation to HTX activity. Exchanges, banks, and financial institutions operating outside UK jurisdiction face no mandatory obligation to treat HTX as a sanctioned counterparty — even as TRM urged them to consider the exchange an “elevated sanctions-evasion risk.”
That jurisdictional patchwork is arguably the most important structural weakness in the current enforcement picture. Wallet rotation by a sanctioned entity is a technical problem, but the absence of coordinated international designation means the problem operates inside a much larger regulatory gap. Until OFAC or European authorities move, the practical reach of the UK action remains limited — and HTX’s global operations continue under conditions where most of the world’s compliance infrastructure has no formal obligation to act.
