The petition, filed May 15 in the U.S. District Court for the Southern District of New York, targets $344,149,759 in USDT sitting in two Tron-based wallets that Tether froze in late April in coordination with U.S. law enforcement. The petitioners are survivors and relatives of victims from Iranian-backed terrorist attacks, including survivors of a 1997 Hamas suicide bombing in Jerusalem. They hold long-standing U.S. court judgments against the Islamic Republic of Iran totaling billions of dollars, awards that have gone largely unpaid.

The two wallet addresses at issue, TTiDLWE6fZK8okMJv6ijg42yrH6W2pjSr9 and TNiq9AXBp9EjUqhDhrwrfvAA8U3GUQZH81, were designated by the U.S. Treasury's Office of Foreign Assets Control (OFAC) on April 24, 2026 as belonging to Bank Markazi, Iran's central bank, with operational ties to the IRGC-Qods Force and Hezbollah. The April 24 action was an update to Bank Markazi's existing entry on OFAC's Specially Designated Nationals list, a designation that dates to 2019 and was originally issued for funding the IRGC and Hezbollah. That pre-existing legal framework gave the current designation immediate force. Tether had already frozen the funds one day earlier, on April 23, acting in pre-coordination with U.S. law enforcement ahead of the formal OFAC announcement rather than as a unilateral initiative. On-chain data from TRM Labs shows the two wallets accumulated roughly $370 million in USDT across approximately 1,000 inbound transactions between March 2021 and late 2023. Less than 7 percent of those inflows, about $25 million combined, ever left the wallets. The pattern is consistent with reserve storage rather than active operational use.

Lead attorney Charles Gerstein of Gerstein Harrow is arguing that Tether's technical architecture is legally indistinguishable from custodianship. In court filings, Gerstein wrote: "USDT is controlled by a centralized entity. Tether possesses the technical capacity to immobilize wallet addresses, blocklist accounts, and under certain circumstances, eliminate balances and redistribute tokens to alternative addresses." The specific mechanism Gerstein is requesting is a burn-and-reissue process: Tether would destroy the frozen tokens on-chain and reissue an equivalent amount to a new wallet under court supervision. That process is technically available to Tether as the USDT contract's sole administrator, but it has not been tested at this scale in U.S. federal court. No ruling has been issued; the case remains at petition stage.

Gerstein is running a parallel version of the same legal theory in a separate case targeting Arbitrum DAO over roughly $71 million in ETH connected to North Korea's Lazarus Group via the KelpDAO exploit, and previously raised similar arguments against Railgun, a privacy protocol. The core claim across all three cases is that crypto infrastructure capable of freezing sanctioned assets is not neutral technology. Gerstein argues that courts can compel these platforms to redirect frozen property to victims who hold enforceable judgments. Tether's statement from April read, in part: "Tether supports the freeze of more than $344 million in USD₮ in coordination with OFAC and U.S. law enforcement." The company has not publicly responded to the May 15 petition as of publication.

The implications extend well beyond the United States. USDT on the Tron network is foundational payment infrastructure across South Asia and sub-Saharan Africa, precisely because Tron transactions are fast and carry low fees. India ranks first globally in crypto adoption and Pakistan ranks third, according to the TRM Labs 2025 Report. Both countries rely heavily on Tron-based USDT for remittances and peer-to-peer commerce. In Africa, Nigeria alone receives over $59 billion in crypto annually, and a survey found 69 percent of Kenyan crypto users prefer USDT on Tron for everyday transactions. Standard Chartered has projected that dollar-backed stablecoins could draw $1 trillion from emerging-market banks over three years, with Egypt, Pakistan, Nigeria, South Africa, and India among the most exposed nations. If U.S. courts confirm that frozen USDT can be court-ordered for reissuance to third parties, Tether's exposure to legal process effectively becomes global. Wallets that have unknowingly transacted with sanctioned entities face heightened risk of collateral freezes, and developers building payment applications on Tron-based USDT rails face new compliance questions they have not previously had to answer.

Tether's enforcement record provides context for how seriously the company takes this coordination role. Since 2023, Tether has blacklisted more than 7,268 addresses and frozen over $4 billion in USDT. In the 30 days prior to this filing, the company blacklisted 370+ addresses and froze $514.64 million across Ethereum and Tron. By comparison, Circle, the issuer of USDC, has blacklisted 372 addresses on a cumulative basis. The gap reflects both Tether's larger market share and its increasingly active posture with U.S. authorities. Whether a federal judge will now extend that posture to include compelled asset redistribution is the question this case puts directly before the court.
