Cryptocurrency Laundering

What is Cryptocurrency Laundering?

Cryptocurrency LaunderingThe process of obscuring the origin of cryptocurrency obtained from crime by moving it through mixers, chain-hopping, and exchanges before cashing out into fiat.


Cryptocurrency laundering applies traditional placement-layering-integration money-laundering stages to on-chain assets. Attackers from ransomware, theft, scams, or sanctions-evading actors push stolen crypto through privacy-enhancing services. Common techniques include mixers and tumblers (Tornado Cash, Sinbad), chain-hopping across bridges to assets like Monero or stablecoins, peeling chains of small transfers, and laundering through nested exchanges or OTC desks. The US Treasury sanctioned Tornado Cash in 2022 for laundering more than USD 7 billion, including from the Lazarus Group's Ronin Bridge heist. Defences combine on-chain analytics (Chainalysis, TRM, Elliptic), exchange KYC and travel rule compliance, FATF guidance, and law-enforcement seizure of mixers and infrastructure.
