Alexey Pertsev, a Tornado Cash developer arrested in August by Dutch authorities over allegations of facilitating money laundering has had his appeal rejected.
Pertsev will have to stay in jail for at least another two months after his appeal was rejected.
A judge in the Netherlands dismissed the appeal on Thursday, according to Pertsev’s wife, Ksenia Malik.
Pertsev has already been in custody for more than seven weeks, after being arrested in Amsterdam on Aug. 10.
His arrest came two days after the U.S. government addedTornado Cash and 44 associated Ethereum and USDC wallets to its Specially Designated Nationals list.
The U.S. Treasury said the crypto mixing service, which allows users to obscure transactions, had “repeatedly failed to impose effective controls designed to stop it from laundering funds for malicious cyber actors.”
Dutch prosecutors plan to seize and sell Pertsev’s property at auction, according to Malik. She said his car was seized on the day he was arrested and Pertsev’s lawyer told her that prosecutors will sell the vehicle.
