Tether freezes $514M in USDT in 30 days, mainly on Tron, tightening control over suspicious funds.

Tether has frozen over $514 million worth of USDT across about 370 addresses in the past 30 days, primarily on the Tron network, which is favored for its low fees and fast transfers. This move highlights Tether's role not just as a stablecoin issuer but also as a key player in combating fraud and illicit activities by blacklisting suspicious addresses. While this enhances security and regulatory compliance, it raises concerns about centralized control over funds on public blockchains. The trend continues a pattern from 2025, where Tether froze and sometimes destroyed billions in USDT linked to illicit activities, emphasizing that USDT is liquid but subject to issuer control.
