HTX Wallet Changes Complicate UK Sanctions Tracking, TRM Labs Finds

• TRM Labs found HTX rotates wallets across four blockchains, complicating UK sanctions tracking through static address-based screening methods significantly reduced.
• Behavior-based attribution analyzes transaction patterns to identify newly created wallets linked with sanctioned entities despite constant address changes efficiently.
• HTX rejected TRM Labs’ findings, calling wallet rotations routine security operations while UK regulators pursue separate legal proceedings concurrently ongoing.

 

HTX’s frequent wallet changes are complicating UK sanctions tracking by reducing the effectiveness of traditional blockchain screening methods, according to blockchain intelligence firm TRM Labs. The firm found that the exchange regularly rotates wallet addresses across four major blockchain networks, making static address-based monitoring significantly less reliable.

According to the report, HTX cycles its hot wallets and funding addresses every few hours across TRON, Ethereum, BNB Smart Chain, and Solana. Consequently, investigators relying on known wallet addresses may struggle to follow the exchange’s onchain activity because previously identified wallets quickly become inactive.

TRM Labs linked the findings to sanctions imposed by the UK Foreign, Commonwealth and Development Office in May 2026. The sanctions targeted Huobi Global S.A., now operating as HTX, over allegations that it facilitated Russian sanctions evasion. Despite those restrictions, the report noted that the exchange has remained operational while repeatedly changing its wallet infrastructure.

According to Ari Redbord, Global Head of Policy at TRM Labs, HTX replaces wallet addresses every few hours, making static screening tools increasingly ineffective. He explained that investigators cannot rely solely on fixed address lists because the exchange constantly introduces new wallets.

Behavior-based monitoring gains importance

TRM Labs argued that behavior-based attribution offers a stronger alternative to conventional wallet screening. Instead of tracking individual addresses, the approach analyzes transaction patterns and onchain behavior to identify links between newly created wallets and known entities. Moreover, the firm explained that behavior-based systems can recognize fresh wallets as they become active. Consequently, investigators can associate those addresses with sanctioned entities almost as quickly as they appear on the blockchain.

TRM Labs described HTX‘s strategy as creating a constantly changing onchain footprint that challenges traditional compliance methods. Therefore, organizations depending only on static wallet databases could overlook transactions connected to the sanctioned exchange. HTX rejected TRM Labs’ characterization of its wallet activity, stating that the wallet changes reflect routine security measures commonly used across the cryptocurrency industry.

Additionally, the exchange disGmissed suggestions that the practice was intended to avoid regulatory screening and declined to provide further comment on the report. HTX also reiterated that regulatory compliance remains one of its highest priorities. The exchange added that it actively follows applicable regulatory requirements across every jurisdiction where it operates,

UK scrutiny extends beyond sanctions

Besides the sanctions imposed in May, HTX also faces separate regulatory action in the United Kingdom. In February, the Financial Conduct Authority began legal proceedings against the exchange over allegations that it published unlawful financial promotions.

The latest findings from TRM Labs add another dimension to the ongoing scrutiny by highlighting how rapidly changing wallet infrastructure can complicate blockchain-based sanctions enforcement. At the same time, the report suggests that behavior-based attribution offers investigators a more effective method for identifying sanctioned entities despite constant wallet rotation.

TRM Labs’ report highlights how frequent wallet rotation can complicate UK sanctions tracking by weakening static blockchain screening methods. The findings also suggest that behavior-based attribution provides investigators with a more adaptable way to identify sanctioned entities despite constant wallet changes.
