Ksenia Malik, the wife of Tornado Cash creator Alexey Pertsev Wife has lashed out at Dutch authorities for treating her husband like a "dangerous criminal" following his arrest last week.

The Dutch Fiscal Information and Investigation Service (FIOD) arrested Pertsev on Aug. 12 over an alleged use of the Ethereum-based privacy tool to launder money and conceal criminal financial flows.

Speaking to Cointelegraph, Malik confirmed that Pertsev remains in the hands of Dutch authorities and has not had the chance to contact him since he was put behind bars.

“He’s kept in prison as if he were a dangerous criminal,” Malik said, as she expressed her concern that Pertsev was arrested without warning over what she sees as a harmless activity:

Malik said that she can “only guess how he is doing and how difficult it is for him right now,” as the Dutch authorities have completely barred her [or anyone] from any contact with him, not even “one short call.”

Despite Malik feeling helpless in this regard, she isn’t without support. Decentralized finance (DeFi) aggregator 1inch has organized a rally in Amsterdam Aug. 20, to show support for Pertsev and to stand for developers’ rights to create open-source software.

1inch has been particularly vocal about the matter, having said that the arrest of Pertsev threatens to “create a dangerous precedent,” as it could “kill the entire open-source software segment” if developers are held responsible for any software they create that is misused by others.
