Dutch authorities arrest suspected Tornado Cash developer

Authorities in the Netherlands have arrested a developer suspected to be involved in money laundering through the crypto mixing service Tornado Cash.

The Fiscal Information and Investigation Service (FIOD), an agency in the Netherlands responsible for investigating financial crimes, officially announced the arrest of a 29-year-old man in Amsterdam on Friday.

The man has allegedly been involved in facilitating criminal financial flows and money laundering through Tornado Cash, the authority said.

The FIOD pointed out that it hasn’t ruled out multiple arrests in the case, noting that its Financial Advanced Cyber Team (FACT) launched a criminal investigation against Tornado Cash in June 2022.

According to the FACT, Tornado Cash has allegedly been used to conceal large-scale criminal money flows, including crypto hacks and scams.

“These included funds stolen through hacks by a group believed to be associated with North Korea. Tornado Cash started in 2019 and according to FACT it has since achieved a turnover of at least seven billion dollars,” the announcement notes.

The news comes shortly after the United States Treasury Department placed dozens of Tornado Cash addresses on the sanctions list of the Office of Foreign Asset Control (OFAC) on Aug. 8. Circle, a major cryptocurrency firm and the issuer of USD Coin (USDC), subsequently froze 75,000 USDC linked to OFAC-sanctioned addresses.

Due to the sanctions, it’s now illegal for any U.S. person or entity to interact with Tornado Cash’s smart contract addresses. Penalties for willful noncompliance can range from fines of $50,000 to $10,000,000 and 10 to 30 years imprisonment.

The Treasury’s move has triggered the rapid developments of events around Tornado Cash. According to some sources, a few more people supposedly involved in the mixer were also reportedly arrested in the United States and Estonia. The arrested individuals allegedly included Roman Panchenko in Seattle and Nikita Dementyev in Tallinn.

Many in the crypto community have expressed outrage over authorities arresting developers and other people involved in the development of Tornado Cash. Industry observers pointed out that charging code writers for creating privacy tools contradicts the principles of a free society.

Amid the reports, Tornado Cash’s Discord channel was reportedly deleted on Friday. Its official Telegram group is still intact at the time of writing.

Based on Ethereum, Tornado Cash is a tool allowing users to obfuscate their crypto transactions to protect their anonymity by scrambling information trails on the blockchain. Ethereum co-founder Vitalik Buterin claimed that he used Tornado Cash to donate funds to Ukraine to protect the financial privacy of the recipients.
