A $225 Million Seizure: The Largest In USSS History

This seizure marks the largest-ever crypto recovery in the history of the U.S. Secret Service.

Coinbase’s “Key Role” In Investigation

According to a detailed blog post published by Coinbase, the company worked hand-in-hand with the USSS and other crypto exchanges during a 2024 “investigative sprint” to identify fraudulent accounts, trace blockchain transactions, and flag scam victims.

How Coinbase Helped Identify Scam Victims

Between February 26th and February 29th, 2024, Coinbase analysts used blockchain forensics tools to trace illicit crypto flows across the network. These efforts enabled the Secret Service to pinpoint over 130 Coinbase users who had unknowingly fallen victim to the scam, resulting in reported losses of $2.3 million.

The insights provided by the crypto exchange were crucial in helping federal agents connect the dots between multiple wallet addresses and illicit activities across various platforms.

OKX & Southeast Asia Scam Compounds

Further blockchain tracking efforts revealed that a substantial portion of the seized funds had been funneled through OKX, a major international crypto exchange.

The investigation uncovered that 140 OKX accounts were tied to individuals operating out of so-called scam compounds in Southeast Asia, hubs believed to be central in executing pig butchering schemes.

This international dimension highlighted the global scale of crypto crime, and the urgent need for coordinated cross-border action.

Tether’s Role: Freezing & Burning $225 Million

Stablecoin issuer Tether also played a crucial role in the operation. In 2023, Tether complied with a DOJ request to freeze 39 wallet addresses holding USDT linked to the scam, amounting to $225 million.

These tokens were later burned, effectively removing them from circulation.

Reissuing and Transferring To The Secret Service

After burning the tokens, Tether reissued an equivalent amount of USDT, which was then transferred to a wallet under Secret Service control.

This on-chain process was transparent and verifiable in real-time, offering a compelling use case for how blockchain can enhance accountability in financial investigations.

The Bigger Picture

This isn’t an isolated incident. Around the world, law enforcement agencies are increasingly leveraging blockchain analytics to combat cybercrime and track stolen funds.

Recent Global Crypto Seizures

• Australia (May 2025): Federal police seized $2.6 million USD believed to be part of a 950 BTC theft from a French crypto exchange in 2013.

• Germany (February 2025): Authorities confiscated $38 million USD from eXch, a crypto platform tied to laundering funds after the Bybit $1.4 billion hack.

These cases demonstrate that, while cryptocurrency investment may offer new avenues for fraud, it also equips investigators with unprecedented visibility into fund flows, unlike traditional finance.
