Tornado Cash is a decentralized, non-custodial cryptocurrency mixing protocol deployed on Ethereum in December 2019, co-founded by Roman Storm, Roman Semenov, and Alexey Pertsev. It was sanctioned by the U.S. Treasury's Office of Foreign Assets Control (OFAC) in August 2022 for allegedly laundering over $7 billion in virtual currency, including hundreds of millions stolen by North Korea's Lazarus Group; the sanctions were later lifted in March 2025 following a Fifth Circuit ruling that immutable smart contracts do not constitute sanctionable 'property' under IEEPA. All three co-founders face or have faced criminal proceedings: Pertsev was convicted in the Netherlands in May 2024 and sentenced to 64 months in prison, Storm was convicted on one of three counts in the U.S. in August 2025, and Semenov remains at large.

TradeOgre was an unregistered, no-KYC cryptocurrency exchange founded around 2018 and known for listing privacy coins including Monero (XMR) and Pirate Chain. On September 18, 2025, the RCMP executed Canada's largest-ever cryptocurrency seizure, dismantling the platform and seizing over CAD $56 million (approximately USD $40 million) in digital assets. Investigators determined that the majority of funds transacted on the platform came from criminal sources, including ransomware proceeds, darknet market activity, hacking exploits, and fraud schemes.
