Blockchain researchers have raised concerns about the United Kingdom’s sanctions against crypto exchange HTX, arguing that the move may have created broad collateral damage across the industry’s compliance system.
In an X post, Galaxy Digital’s head of research, Alex Thorn, said the UK adding “all of HTX” to its sanctions was “problematic” because the exchange has many legitimate users. Thorn pointed to differences in how stablecoin issuers decide when to freeze tokens, saying there’s a big divergence in enforcement practices.
Security researcher Taylor Monahan said in an X post that the HTX sanctions undermined years of work to encourage decentralized finance (DeFi) protocols to screen and block stolen funds. She argued that most HTX users are legitimate.

Blockchain investigator ZachXBT also criticized the sanctions, calling them “a bit of an overreach.” He said HTX address tainting onchain has been “catastrophic.”
“Basically now I’ve had to ignore the sanctions category when tracing cases by exposure since ‘risk’ itself has become meaningless,” he said.
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.

HTX has since denied the allegations, saying the sanctioned entity is separate from the online exchange.
Despite this, a Global Ledger report said that HTX processed about $21.06 billion in high-risk crypto flows between 2021 and May 2026. Of that total, at least $7.64 billion was linked to Russian high-risk entities and darknet markets, including Garantex, its successor Grinex, A7A5 and Hydra.
The sanctions appeared to have had effects downstream. Trump-linked DeFi project World Liberty Financial later froze HTX-linked addresses after what it described as sanctions compliance reviews. HTX responded by delisting the DeFi platform’s USD1 stablecoin and suspending several trading pairs.
