HTX wallet rotation amid UK sanctions was reported after the UK’s Office of Financial Sanctions Implementation designated HTX as Huobi Global S.A. on May 26. The UK sanctions package targeted the A7 network, which the designation described as used to evade restrictions and to channel funds to Russia’s invasion of Ukraine. The UK government also flagged HTX as a major global cryptocurrency exchange suspected of having channeled more than $1.5 billion to the Kremlin.
TRM Labs reported that HTX rotated hot wallets across TRON, Ethereum, BNB Smart Chain and Solana, moving activity between chains as part of an on-chain wallet rotation strategy. The firm said HTX retired each hot wallet and associated funding address within hours and shifted incoming and outgoing activity to newly created wallets, repeatedly replacing addresses on short timelines.
TRM noted that a block list built on specific HTX addresses goes stale within hours, which creates difficulty for address-list screening unless the underlying behavior behind the wallets is tracked. TRM compared HTX’s approach to Garantex’s post-designation playbook, citing Garantex’s creation of Grinex after its takedown in March 2025 and migration of liquidity through the A7A5 stablecoin, and reported that HTX retained its public brand while rebuilding at the wallet level rather than changing brands.
The report documented these actions across the named chains.
OFAC and the EU have not designated HTX, so freeze obligations fall only on UK-regulated firms. TRM Labs urged other jurisdictions and private-sector firms to treat HTX as an elevated sanctions-evasion risk. TRM Labs presented that advisory within its analysis of HTX’s post-designation behavior.
An HTX spokesperson told Decrypt that the behavior flagged in TRM Labs’ report is benign, describing the activities as routine and security-driven platform operations. “The technical activities referenced in TRM’s report reflect routine, security-driven platform operations common across the industry.” The spokesperson said the company rejects any characterization otherwise.
This section records the limited legal reach of the UK designation, TRM Labs’ elevated-risk advisory, and HTX’s public denial. It does not describe operational or technical mechanisms.
The UK designated HTX as Huobi Global S.A. under its financial sanctions. TRM Labs reported that HTX rotated hot wallets across TRON, Ethereum, BNB Smart Chain and Solana, retiring individual hot wallets and associated funding addresses within hours and shifting incoming and outgoing activity to newly created wallets.
TRM reported that a block list built on specific HTX addresses goes stale within hours, complicating address-list screening unless the underlying wallet behavior is tracked. Other sanctioning authorities have not designated HTX, so freeze obligations fall only on UK-regulated firms; TRM urged others to treat HTX as an elevated sanctions-evasion risk and HTX described the flagged activity as routine, security-driven platform operations.
