U.S. Secret Service Nets Its Largest-Ever Cryptocurrency Seizure
In a milestone operation announced June 18, 2025, the U.S. Secret Service, backed by the FBI and the Department of Justice (DOJ), executed the agency’s largest-ever cryptocurrency seizure—$225.3 million in crypto assets—tying them to sophisticated investment fraud schemes, often termed “pig-butchering” scams. Central to the recovery was Coinbase, whose blockchain analysis capabilities helped law enforcement pinpoint stolen assets, identify affected customers, and build a compelling legal case for asset forfeiture.
Tracing the Trail: The Role of Coinbase
Coinbase was engaged in an “investigative sprint” alongside the Secret Service a few weeks ago, from February 26 to 29, 2024, to trace millions of dollars in unlawful transfers. By using forensic blockchain analysis and subpoenaed transactions, Coinbase flagged over 130 customers who collectively lost $2.3 million to the scams. The team traced money moving from illicit wallets that belonged to OKX accounts, many of which were controlled by individuals forced into scam farms across Southeast Asia.
Tether’s Critical Move: Freeze, Burn, Reissue
In November 2023, Tether froze 39 wallet addresses with the stolen USDT worth approximately $225 million, after alerts from Tether and OKX engaged law enforcement officials. Next, Tether conducted an on-chain “burn” of the tokens—permanently deleting them from circulation— and then minted the same amount of new USDT and sent it to a Secret Service wallet. This process was frank and clearly illustrated how blockchain-based tools can bring transparency and accountability to governmental efforts.
The Scam Mechanism: What Is Pig-Butchering?
Pig-butchering scams involve building false trust—often through romantic or business façades—then coaxing victims into sending funds under the guise of crypto investments. Once victims transfer their savings, scammers disappear, frequently running operations from enforced scam compounds in countries like Myanmar or Cambodia. In this case, over 400 victims were identified, many losing substantial amounts.
DOJ and Law Enforcement Response
On June 18, the DOJ initiated a civil forfeiture action in the U.S. District Court for D.C., seeking to forfeit the seized crypto as proceeds of fraud and money laundering. U.S. Attorney Jeanine Pirro, DOJ Criminal Division head Matthew Galeotti, Secret Service Agent-in-Charge Shawn Bradstreet, and FBI Special Agent Sanjay Virmani all stressed the importance of this record-setting seizure and increasing importance of crypto fraud prosecution.
Victim Restitution and Next Steps
With funds now secured by the Secret Service, victims can pursue restitution through the FBI’s Internet Crime Complaint Center (IC3), citing code “BT06182025”. The DOJ notes that any surplus over legitimate claims may help fund a U.S. cryptocurrency reserve. While the enforcement process continues, Coinbase has provided customer support and guidance on submitting transaction records to ease victim claims.
Why This Matters
This matter presents grows an increasing frequency of defense against crypto fraud by leveraging the public and private sector. Researchers find that operations in Australia and Germany demonstrate the rise of global enforcement that the blockchain’s transparency provides. With crypto-related fraud raking in billions every year—over $5.8 billion alone in 2024, according to the FBI—it stands to reason that this precedent shows how digital trails and NFT technologies can help recover lost or stolen funds.
The Road Ahead
With the evolution of crypto scams comes the evolution of investigative tools. The range of forensic blockchain tracing, the ability to rapidly freeze payment that is illicit by stablecoin issuers, and unified litigation has ushered in a new era of financial crime prevention. Coinbase’s example of transparency and Tether’s quick response showcase the ability of the private sector to support law enforcement, and a key takeaway on how the early years and future of crypto might develop in terms of governance and consumer protection.
