sanctions

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.

Wallex (legal name: Khalgh Sarvat Sarzamin Parseh / Khalq Tharwat Sarzamin Parseh Company) is Iran's second-largest cryptocurrency exchange by transaction volume, founded in 2018 in Tehran. On June 2, 2026, the U.S. Treasury's Office of Foreign Assets Control (OFAC) added Wallex to its Specially Designated Nationals (SDN) list under Executive Order 13902, citing its operation in the Iranian financial sector and its facilitation of transactions linked to the Islamic Revolutionary Guard Corps (IRGC). The designation was part of Operation Economic Fury, the largest-ever U.S. enforcement action targeting Iran's digital asset sector.

Token 2049 is one of the world's largest crypto conferences, held annually in Singapore and Dubai by Hong Kong-based BOB Group. The event has faced repeated criticism for insufficient sponsor vetting, most notably when OFAC- and UK-sanctioned Russia-linked stablecoin A7A5 was listed as a platinum sponsor and given a speaking slot at the October 2025 Singapore edition. Separately, in March 2025, on-chain investigator ZachXBT publicly flagged multiple Token 2049 sponsors — including DWF Labs, Bitunix, JuCoin, WEEX, and Spacecoin — for fraud, wash trading, and regulatory non-compliance, warning that conference sponsorship carries no implied credibility.
