The UK’s recent sanctions on crypto exchange HTX are making waves across the blockchain research and security community. Industry figures warn that the decision, which targets the entirety of HTX, could disrupt not just the exchange itself but also key systems for compliance and on-chain risk monitoring worldwide.
Experts question the scope of the sanctions
Alex Thorn, head of research at Galaxy Digital, publicly voiced concern on X (formerly Twitter) over what he described as a problematic move by the UK authorities to blacklist “all of HTX.” Thorn explained that the broad categorization puts a large number of legitimate users at risk and breeds practical uncertainty in the application of such sanctions. Galaxy Digital is a US-based financial group specializing in digital assets.
Sharing his view, Alex Thorn argued that sanctioning all of HTX was problematic due to a high volume of legitimate user activity on the exchange, further noting that differing interpretations had arisen among stablecoin issuers over which tokens to freeze.
Security analyst Taylor Monahan echoed these criticisms, stating that the UK’s sweeping measure has undermined years of progress by decentralized finance (DeFi) protocols in tracing and blocking stolen assets. Monahan argued that most HTX users engaged in lawful activity.
Blockchain investigator ZachXBT characterized the sanction as “a step too far.” He explained that tagging all HTX-linked addresses as risky on-chain seriously disrupted ongoing investigations and tracking protocols.
ZachXBT admitted that, when reviewing exposure, he could no longer rely on the UK’s sanction labels for categorization, as the definition of risk had become largely meaningless in practice.
The UK’s reasoning and HTX’s response
The controversy began with the UK’s May 26 ruling to impose sanctions on Panama-based Huobi Global S.A., the company behind HTX. British officials indicated there was reason to believe the company may have supported Russia-linked financial networks.
According to authorities, HTX may have facilitated financial flows and services for entities connected to the Russian government, including sanctioned companies like A7 Limited Liability Company and Garantex. HTX, for its part, has firmly denied all allegations, insisting that the sanctioned corporate entity is legally separate from the exchange platform itself.
On-chain data and market impact
A report from Global Ledger reveals that from 2021 until May 2026, around $21.06 billion in crypto transactions were classified as high risk as they passed through HTX. Of this, at least $7.64 billion was tied directly to high risk Russian entities like Garantex, its offshoot Grinex, A7A5, Hydra, and certain darknet markets.
| Metric | Data |
|---|---|
| Period analyzed | 2021 to May 2026 |
| Total high risk crypto flows | $21.06 billion |
| Russian-linked high risk flows | At least $7.64 billion |
The aftermath of the UK’s decision surfaced quickly. The decentralized finance platform World Liberty Financial, reportedly associated with Donald Trump, froze addresses tied to HTX during compliance checks. HTX then delisted the USD1 stablecoin from its platform and suspended select trading pairs.
Quick glossary: “Address contamination” refers to a blockchain wallet being deemed risky simply because it is connected to addresses tied to sanctions, thefts, or illicit funds. This labeling can create compliance hurdles, restricting related wallets even in the absence of direct violations.
