Tether froze $514M USDT in 30 days, blacklisting $1.26B in 2025, showing stablecoins as enforcement tools.

Tether froze over $514 million worth of USDT across 370 addresses in the past 30 days, mainly on the Tron network, contributing to a total of $1.26 billion frozen in 2025 across Ethereum and Tron. This large-scale freezing highlights how centralized stablecoins like USDT are used as enforcement tools by global regulators and law enforcement to block illicit activities such as fraud, darknet markets, and sanctioned entities. Tether’s blacklist actions are triggered by law enforcement requests, sanctions lists, and proactive investigations, with a significant portion of frozen funds permanently destroyed. This enforcement role is reshaping the crypto market, prompting protocols and exchanges to adjust their compliance and design to avoid losses from blacklisted funds.
