On Thursday, Tether, the company behind the world's largest stablecoin, announced that it has frozen approximately $344 million in USDT tokens across two Tron blockchain wallets. This action was taken in response to requests from US authorities, who flagged the addresses due to suspected connections to illicit activities.
As a result, further movement of these funds has been prevented. The nature of the alleged activities and the identities of those controlling the wallets were not disclosed by the company. However, according to AMLbot, a blockchain analytics firm, the addresses in question appeared in documents and posts related to scams.
This move highlights the ongoing debate surrounding the role of stablecoin issuers in preventing the transfer of funds tied to illegal activities. Recently, the Financial Action Task Force warned that stablecoins are increasingly being used for illicit transactions, including the evasion of sanctions and money laundering.
The transparency of public blockchains allows transactions to be traced, while issuers have the ability to freeze assets under specific conditions. This issue gained attention earlier this month after the $285 million exploit of Drift Protocol, in which attackers transferred hundreds of millions of USDC stablecoins and bridged funds across chains.
Critics argued that Circle, the issuer of USDC, could have acted more swiftly to freeze assets and minimize losses. In response, the company stated that it only takes such actions when legally required or at the request of law enforcement and authorities. Tether claims to collaborate with law enforcement when wallets are linked to sanctions evasion or criminal networks, having supported over 2,300 cases globally across 340 agencies in 65 countries.
The company is also expanding its presence in the US market with the launch of the USAT token, which complies with federal stablecoin regulations. Issued in partnership with Anchorage Digital, a federally regulated crypto bank, this effort is led by former White House crypto advisor Bo Hines.
Furthermore, Tether is preparing for a comprehensive audit of its reserves for the first time, a long-promised step aimed at enhancing transparency and aligning more closely with regulatory expectations for stablecoins.
