HTX denied authorizing a series of disputed cryptocurrency microtransfers on August 20 after some users alleged that funds originating from HTX-linked addresses caused compliance restrictions at Kraken and other exchanges. According to reports from CoinDesk, the exchange stated on August 18 that its internal review found no official transfers or testing activity behind reported deposits. Users reported receiving small USDT deposits from addresses labeled as HTX wallets by blockchain services, with one user reportedly receiving 7.5 USDT in a Coinbase account before being asked to explain the source of the funds. The latest reports show pseudonymous trader 0xZiye posted the first complaint early Tuesday, with Coinbase demanding an explanation or closure threat after receiving the unrequested deposit. As per AMBCrypto, the activities showed recurring Tether [USDT] payments ranging between 3 and 10 USDT with similar amounts and closely grouped timing pointing toward a repeated transfer pattern rather than typical exchange withdrawals.
HTX is examining whether address labels or transaction attribution errors created a misleading origin trail. As reported by CoinDesk, the exchange said it had 'not conducted any related transfers or testing activities' and would not speculate before completing its investigation. The latest statement from Molly, an HTX executive, confirmed the exchange is still tracing the funds and did not rule out address-tagging errors or misread on-chain data. According to AMBCrypto, HTX says it is investigating possibilities including address tagging and on-chain source identification, leaving attribution unresolved. The investigation does not identify the blockchain involved, the sending addresses or the transaction hashes, nor disclose how many recipients had reported deposits or whether any customer assets were at risk.
Some users have described the transactions as 'address poisoning,' while others reportedly said their accounts faced restrictions after receiving the funds. According to CoinDesk, small unsolicited transfers alone do not establish address poisoning, as investigators would need to determine whether the sender resembles a trusted counterparty and whether the transaction was intended to manipulate a recipient's address history. The current reports contain no verified evidence that recipients later sent assets to lookalike addresses, with no losses confirmed. As per AMBCrypto, many recipients reported being frozen out of their accounts shortly after receipt of the deposits, with even small USDT transfers related to HTX may automatically initiate account review processes by receiving exchanges due to sanctions imposed on the platform. The reported HTX transfers present a different scenario from classic address poisoning, where the alleged objective would be to associate a recipient with a sanctioned or compliance-sensitive address, potentially triggering automated screening.
Kraken has confirmed a broader policy of restricting transfers associated with Huobi or HTX, with the exchange stating that U.K. government sanctions require it to restrict funds transferred from Huobi into Kraken customer accounts. The policy followed the U.K.'s May 26 designation of Huobi Global S.A. under its Russia sanctions regime, with the government having reasonable grounds to suspect that the company was involved in making funds or economic resources available to entities in Russia's financial sector. HTX disputed the designation's application to its exchange, arguing that Huobi Global S.A. was distinct from the online platform and saying its operations remained unaffected. However, the U.K. Office of Financial Sanctions Implementation rejected that distinction, with official guidance stating the designation applies to the HTX exchange because OFSI considers Huobi Global to own it under U.K. sanctions rules. Kraken has not said that every incoming transfer from an HTX-labeled address produces a full account freeze, and it has not confirmed that the recent microtransfers caused specific customer restrictions.
A Kraken user group has been created to unite affected users, gather data about frozen funds, and effectively pressure Kraken to address the problem. As per AMBCrypto, this initiative aims to differentiate users who are voluntarily relocating or safeguarding their funds from any official Huobi-led activity. The situation remains delicate as the EU's transaction ban was set for August 23, with UK sanctions already placing limitations on activities related to HTX. An HTX representative using the @HTX_Molly account said the exchange had researched Kraken restrictions during the previous two days and found that some users remained unable to access funds, citing $4.2 million as the highest known amount affected. However, no evidence accompanying the statement established whether that amount belonged to one account, several linked accounts or a transfer under a specific legal hold. The current evidence does not establish intent, and receiving an unsolicited transfer also does not, by itself, show that a recipient knowingly dealt with a sanctioned entity.
