Tether locked more than $344 million in USDT on the Tron blockchain on Thursday. The company blacklisted two large wallets within minutes, and it restricted all token transfers from those addresses. The action followed requests from U.S. law enforcement, according to people familiar with the matter.
Tether Executes Dual USDT Freezes on Tron
On-chain tracker Whale Alert reported the first blacklist involving 212.92 million USDT, valued near $213 million. Minutes later, it flagged a second freeze covering 131.29 million USDT, worth about $131.3 million. Together, the actions immobilized more than $344 million in stablecoins on Tron.
Tether used administrative keys embedded in the USDT smart contract to enforce the freezes. Once blacklisted, the wallets could not send or receive USDT, and the tokens became unusable. However, the Tron blockchain ledger continued to display the balances without alteration.
Tether did not publish a detailed explanation for Thursday’s actions. However, the company has stated in prior cases that it acts after law enforcement requests. It has also cited suspected illicit activity when it blocks wallet addresses.
In January, Tether froze about $182 million across five Tron addresses in one coordinated sweep. The company linked that action to cooperation with U.S. authorities. Over the past three years, Tether reported blocking more than $4.2 billion in USDT tied to criminal activity.
Tron Network Faces Fresh Scrutiny After USDT Blacklisting
Tron has become a preferred network for large USDT transfers because it offers low fees and fast settlement. As a result, major holders often use Tron for high-value transactions. However, the network’s reliance on centralized stablecoin issuers has drawn attention.
On April 21, Tron founder Justin Sun posted on X that Tron is “the most decentralized blockchain in the world.” He made the statement after Arbitrum froze ETH linked to the Kelp DAO exploit. Sun said Tron operates through 27 rotating Super Representatives and lacks protocol-level backdoors.
Two days later, Tether blacklisted two Tron wallets in quick succession. The freezes occurred at the USDT smart contract layer, not at Tron’s core protocol. Still, the actions restricted more than $344 million in tokens on the network.
Tether maintains control over USDT issuance and redemption across supported blockchains. While users hold private wallet keys, Tether can restrict token transfers through contract controls. The latest freezes occurred on April 23, according to Whale Alert data.
