Tether Moves To Freeze $344 Million In Crypto Amid US Probe

A wave of crypto hacks hitting decentralized finance platforms in April has renewed an old argument: should stablecoin companies step in when stolen money passes through their systems? That question is now front and center again after Tether, the world’s largest stablecoin issuer, revealed it froze over $340 million in dollar-pegged tokens at the direct request of US law enforcement officials.

The freeze targeted two separate wallet addresses. Tether said the funds were linked to unlawful conduct but gave no further detail about what the accounts were suspected of doing or who controlled them.

The company coordinates freezes when it finds credible ties to sanctioned entities, criminal networks, or other illegal activity, according to its published policy.

Tether CEO Paolo Ardoino defended the action in a statement released alongside the announcement. “When credible links to sanctioned entities or criminal networks are identified, we act immediately and decisively,” he said. The company did not respond to further requests for comment.

The freeze was carried out in coordination with the Office of Foreign Assets Control, a US Treasury agency responsible for enforcing economic sanctions. That makes this more than a routine compliance move — it signals active cooperation between a major crypto firm and federal authorities at a time when regulatory pressure on the industry continues to mount.

Not everyone welcomed the news. Crypto media outlet Truth for The Commoner pushed back sharply. “Your stablecoins are not your stablecoins. They never were,” the outlet posted on social media.

The reaction reflects a tension that has existed since centralized stablecoins became widely used — the tokens may sit on a blockchain, but the company behind them holds a master switch.

The announcement comes weeks after one of the month’s most damaging incidents — the Drift Protocol exploit, which drained $280 million from the platform. That attack put Circle, the issuer of the USDC stablecoin, under a different kind of scrutiny.

Onchain analyst ZachXBT publicly criticized Circle for failing to freeze USDC funds after the attacker routed stolen money through Circle’s own native bridge over six consecutive hours.

“No USDC was frozen,” ZachXBT noted, arguing that centralized issuers have a responsibility to act quickly when hacks are in progress.

The criticism drew wide attention across the crypto community and intensified calls for clearer standards around when and how stablecoin issuers should intervene.
