Kraken temporarily restricted customer accounts after nearly 12,000 unsolicited cryptocurrency transfers were sent to addresses connected to the exchange between Aug. 17 and 24, according to an Aug. 25 report.

The exchange later restored access after reviewing the affected accounts. The disputed funds are still being held separately because they were reported as linked to sanctioned wallets. Arkham Intelligence tagged the sending wallet as connected to HTX, while HTX denied involvement and said it is examining whether the label was wrong or whether a third party was responsible.

Wave of microtransfers triggered reviews

The transfers appear to have been a large-scale dusting-style event, with small amounts of cryptocurrency sent to Kraken-linked addresses without being requested by recipients. Because the funds were reportedly tied to sanctioned wallets, Kraken responded by restricting impacted customer accounts while it carried out compliance checks.

After those reviews were completed, account access was restored. Kraken nonetheless kept the questioned funds segregated, reflecting the distinction between reviewing customer activity and deciding how to handle incoming assets that may have sanctions exposure.

HTX link remains disputed

Arkham Intelligence identified the wallet that sent the transfers as connected to HTX. That label, however, does not establish that HTX controlled the wallet or directed the activity behind the transfers.

HTX rejected claims of involvement. The exchange said it is investigating whether the address may have been mislabeled or whether another party could have used the wallet connection in a way that created a false appearance of HTX participation.

Compliance systems face a difficult edge case

The episode underscores a recurring problem for compliance programs that put heavy weight on direct wallet exposure. A recipient can receive crypto from a sanctioned address without asking for it, controlling the sender, or even being aware of the transfer until after it arrives.

That means exchanges cannot automatically treat every unsolicited transfer as proof of a sanctions breach by the customer receiving it. Reviews may need to consider the value of the transaction, who appears to own the assets, the timing of the transfer, and whether the customer’s broader behavior suggests any active involvement.

Sanctions backdrop raises sensitivity

The timing adds to the scrutiny. Sanctions on HTX’s Huobi Global entity took effect in the UK and EU around Aug. 2026, increasing the sensitivity around even very small transfers that appear to touch addresses associated with the platform.

For now, Kraken has restored the affected accounts, and the questioned funds remain isolated. Kraken and HTX have not announced a joint investigation or provided a timeline for any further action, leaving the wallet attribution and the source of the transfer campaign unresolved.
