On Thursday, Tether, the company behind the world's largest stablecoin, announced that it had frozen approximately $344 million worth of USDT tokens across two wallets on the Tron blockchain, in response to requests from US authorities. The freeze was enacted after the addresses were flagged for suspected links to illicit activity, effectively preventing any further movement of the funds. The nature of the activity and the identities of the wallet controllers were not disclosed by the company. However, according to blockchain analytics firm AMLbot, the addresses appeared in scam-related documents and posts.
This move comes as the debate surrounding stablecoin issuers' role in preventing illegal money transfers is reignited. The Financial Action Task Force (FATF) recently cautioned that stablecoins are increasingly being utilized for illicit transactions, including sanctions evasion and money laundering.
Public blockchains allow transactions to be traced, while issuers have the ability to freeze assets under specific conditions. This issue gained attention earlier this month following the $285 million exploit of Drift Protocol, where attackers transferred hundreds of millions of USDC stablecoin and bridged funds across chains.
Critics argued that Circle (CRCL), the issuer of USDC, could have acted more swiftly to freeze assets and limit losses, while the company stated that it only takes such actions when legally required or at the request of law enforcement and authorities. Tether claimed that it collaborates with law enforcement when wallets are linked to sanctions evasion or criminal networks and has supported over 2,300 cases globally across 340 agencies in 65 countries. The company is also expanding its presence in the US market, having launched the USAT token, which is compliant with federal stablecoin regulation, in partnership with federally regulated crypto bank Anchorage Digital, 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 towards enhancing transparency and aligning with stricter regulatory expectations for stablecoins.
