- The USDT freeze delay exploited for laundering $78 million.
- AMLBot highlighted the multi-signature lag issue.
- Automation bots detected freeze alerts, aiding illicit activities.

AMLBot discovered a vulnerability in Tether’s USDT freeze mechanism leading to $78 million laundered since 2017. This flaw occurs due to transaction enforcement delays on both Tron and Ethereum platforms.
Slava Demchuk, CEO of AMLBot, explained that while bots were not directly observed, their patterns suggest automation. Tools monitor freeze alerts, giving criminals up to one hour to move funds using this delay.
The exploitation of Tether’s system has affected both Tron and Ethereum networks. This lag inherently exposes these ecosystems to unlawful activities, impacting the trust and integrity of stablecoin transactions.
Financial implications include the potential need for rapid compliance updates across Tether’s technology to deter these actions. Regulatory scrutiny may intensify, influencing compliance mechanisms for stablecoin issuers worldwide.
The reliance on multi-signature contracts caused the freeze delays. Faster, atomic processes are crucial wherein authorizations occur in a single transaction. This mechanism ensures immediate enforcement, closing the current exploit gap evident in Tether’s contract logic.
Tether must address these exploitable gaps, potentially incorporating instant freezing procedures. Regulatory expectations may demand swifter action from stablecoin issuers to prevent further violations. This emphasizes enhancing compliance frameworks consistent with technological advancements.
The timing and movement patterns strongly support automation and rapid exploitation of the delay. – Slava Demchuk, CEO, AMLBot
