Tether Freezes Over $514 Million in USDT Across Tron and Ethereum in 30 Days

Tether immobilized over $514 million in USDT across the Tron and Ethereum networks during a 30-day span, according to BlockSec analytics cited by MoneyCheck.

MoneyCheck reported that 370 wallet addresses were added to the blacklist throughout the period, with the majority of restricted funds concentrated in Tron.

Within that same 30-day window, MoneyCheck said 328 Tron-based addresses appeared on the blacklist and that those wallets collectively contained approximately $505.9 million in USDT tokens.

MoneyCheck also said BlockSec’s USDT Freeze Tracker identified 42 Ethereum-based addresses that received blacklist designations, with those restricted wallets containing roughly $8.73 million in frozen USDT.

The Crypto Times framed the same enforcement window as Tether blacklisting 370 wallet addresses and freezing $514.64 million in USDT over the past 30 days, with Tron accounting for 328 blacklisted addresses and $505.91 million frozen while Ethereum accounted for 42 addresses and $8.73 million.

MoneyCheck said Tron represented the overwhelming majority of recent asset immobilization efforts, adding that Tron consistently features prominently in enforcement statistics related to frozen digital assets.

The Crypto Times described the enforcement mechanics as address-level controls invoked through the addBlackListfunction in the USDT smart contract, where attempts to send or receive USDT from a blacklisted wallet are automatically reverted at the block level.

MoneyCheck reported that the issuer implements wallet restrictions through smart contract-level controls embedded in the token’s code, and that blacklisted addresses lose all ability to transfer affected USDT until Tether explicitly reverses the restriction.

The Crypto Times said the frozen USDT remains visible on-chain but cannot be transferred or redeemed, and it described a “burn and reissue” mechanism in cases involving formal law enforcement seizures.

MoneyCheck added that BlockSec’s 2025 analysis found most enforcement actions remain permanent, with only 3.6% of blacklisted wallet addresses subsequently removed from restricted status.

MoneyCheck said the enforcement wave underscores Tether’s expanding role in combating suspected fraudulent cryptocurrency transactions, and it linked the blacklist mechanism to restricting access to funds associated with fraudulent schemes, regulatory violations, and ongoing legal proceedings.

The Crypto Times said CEO Paolo Ardoino has framed the freeze capability as a feature rather than a bug, arguing that USDT creates a safer financial environment than fiat because every transaction is traceable.

MoneyCheck also reported that the increasing deployment of blacklist capabilities has reignited conversations within cryptocurrency communities about centralization, because stablecoin issuers grant themselves unilateral authority over user account balances.

Cointelegraph added that Tether said it had frozen about $4.2 billion in tokens in three years over links to illicit activity, with some $3.5 billion locked since 2023 as authorities increased efforts to curb crypto-related crime.

Cointelegraph further said that in April Tether worked with the US Treasury’s Office of Foreign Assets Control and law enforcement agencies to freeze more than $344 million in USDT across two Tron addresses that US officials said were linked to suspected sanctions evasion involving Iran.
