Coinbase Plays Key Role in Historic $225 Million Cryptocurrency Seizure by US Secret Service
On June 18, 2025, the United States Department of Justice filed papers to seize over $225 million in cryptocurrency, marking the largest crypto seizure in the history of the US Secret Service. This substantial recovery involves funds allegedly stolen by "pig butchering" scammers—fraudsters who trick victims into investing in fraudulent crypto schemes before disappearing with their money. Central to this landmark investigation was Coinbase, one of the leading cryptocurrency exchanges in the country, which played a pivotal role in supporting law enforcement efforts.
Collaborative Investigative Effort to Combat Crypto Scams
In a blog post published on June 24, 2025, Coinbase revealed it had joined a rapid “investigative sprint” with the US Secret Service and several other exchanges throughout 2024 to trace and analyze illicit crypto transactions. Between February 26 and 29 last year, Coinbase’s team traced millions in cryptocurrency linked to scam wallets and suspicious account activities. This blockchain analysis helped identify over 130 Coinbase customers who unknowingly suffered losses totaling approximately $2.3 million.
According to Coinbase, the detailed chain flow analysis and subpoena-backed data collection were critical in flagging scam victims and building a robust case against the perpetrators. The Secret Service further traced some of the seized funds to roughly 140 accounts on another exchange, OKX. Intriguingly, many of those accounts were held by individuals believed to be detained at scam compounds in Southeast Asia, a hotspot for this type of criminal operation.
Tether’s Crucial Role: Freezing and Burning $225 Million in USDT
In addition to Coinbase’s investigation, Tether, issuer of the popular USDT stablecoin, played an essential role in the operation. The Department of Justice acknowledged Tether for freezing 39 wallet addresses in 2023 that collectively held the $225 million primarily in USDT tokens. Subsequently, Tether permanently "burned" these tokens—a process that removes tokens from circulation by sending them to inaccessible wallet addresses.
Coinbase noted that immediately after burning the compromised USDT tokens, the equivalent amount of new USDT was reissued and transferred to a wallet controlled by the Secret Service. This sequence of actions was publicly visible on the blockchain, showcasing a transparent example of how cryptocurrency’s inherent features can aid law enforcement operations.
Broader Context: Global Crackdowns on Crypto-Related Crime
This seizure is part of a growing international crackdown on illicit crypto activities. For instance, in May 2025, the Australian Federal Police confiscated nearly 25 Bitcoin worth over $2.6 million, connected to a 2013 theft involving 950 BTC from a French exchange. Similarly, in February, German authorities seized approximately 34 million euros ($38 million) in crypto assets linked to laundering operations on eXch, a platform connected to a $1.4 billion hack of the Bybit exchange.
Enhancing Transparency and Building Trust in Crypto Law Enforcement
The Coinbase-supported seizure of $225 million in stolen cryptocurrency marks a significant victory against crypto-related fraud and highlights the evolving collaboration between private crypto entities and public law enforcement agencies. The transparent blockchain processes demonstrated during this operation may serve as a model for future investigations, reassuring investors and regulators that the crypto ecosystem can be navigated safely with effective oversight.
Coinbase’s statement underscores the importance of continued partnerships among exchanges, stablecoin issuers, and federal agencies to safeguard users and uphold the integrity of digital assets.
