UK sanctions on HTX are drawing fire from blockchain researchers over crypto risk signaling

Blockchain researchers say the United Kingdom’s sanctions against HTX may be doing more than targeting one exchange: they argue the move is muddying how the industry spots and scores crypto risk. For PSPs, compliance teams, and chain analysts, the uncomfortable part is that “sanctions exposure” can start to mean less if broad address tainting is treated as a blunt instrument.

1. Galaxy Digital’s head of research, Alex Thorn, said in an X post that the UK adding “all of HTX” to its sanctions was “problematic” because the exchange has many legitimate users. His point was not subtle: sanctions tools only work cleanly when the line between bad actors and ordinary flow is still visible.
2. Security researcher Taylor Monahan said the HTX sanctions undermine years of work pushing DeFi protocols to screen and block stolen funds. In her view, most HTX users are legitimate, so sweeping sanctions risk weakening the very compliance habits the sector has been trying to build.
3. Blockchain investigator ZachXBT took aim at the onchain consequences, calling the sanctions “a bit of an overreach.” He said HTX address tainting onchain has been “catastrophic” and added: “Basically now I’ve had to ignore the sanctions category when tracing cases by exposure since 'risk' itself has become meaningless,” which is exactly the kind of sentence compliance teams do not want to hear about their tooling.
4. The criticism follows the UK’s May 26 sanctions against Huobi Global S.A., the Panamanian company behind HTX, over alleged support for Russia-linked financial networks. UK authorities said there were reasonable grounds to suspect HTX had supported Russia’s government through financial services and funds facilitated by A7 Limited Liability Company and Garantex, both sanctioned entities.
5. HTX disputes the UK sanctions, saying the sanctioned entity is separate from the online exchange. But a Global Ledger report said HTX processed about $21.06 billion in high-risk crypto flows between 2021 and May 2026, with at least $7.64 billion linked to Russian high-risk entities and darknet markets, including Garantex, its successor Grinex, A7A5 and Hydra. That is the sort of number that tends to shape how banks, PSPs, and analysts treat counterparty exposure, whatever the legal argument is.

The downstream effect is already visible. Trump-linked DeFi project World Liberty Financial froze HTX-linked addresses after what it described as sanctions compliance reviews, and HTX responded by delisting the DeFi platform’s USD1 stablecoin and suspending several trading pairs. In practice, that is how a sanctions decision turns into a broader routing problem for crypto payments and compliance systems.
