On Thursday, Tether, the issuer of the world's largest stablecoin, announced that it had frozen $344 million worth of USDT tokens in two wallets on the Tron blockchain, following a request from US authorities. The freeze was implemented 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 individuals controlling the wallets were not disclosed by the company. However, blockchain analytics firm AMLbot reported that the addresses were mentioned in scam-related documents and posts.
This development comes as the debate surrounding the role of stablecoin issuers in preventing the transfer of funds linked to illegal activities is gaining momentum. The Financial Action Task Force has recently cautioned that stablecoins are increasingly being used for illicit transactions, including sanctions evasion and money laundering. While public blockchains allow transactions to be tracked, issuers have the ability to freeze assets under certain conditions. The issue has been highlighted 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, the issuer of USDC, could have acted faster to freeze assets and limit losses, while the company claimed that it only takes such actions when legally required or at the request of law enforcement and authorities. Tether has stated 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. This effort is being led by former White House crypto advisor Bo Hines. Furthermore, Tether is preparing for a full audit of its reserves for the first time, a long-promised step aimed at improving transparency and aligning with tighter regulatory expectations for stablecoins.
