Chainalysis's 2025 report reveals a dramatic 700% increase in crypto transactions linked to sanctioned entities, totaling $104 billion. This surge has driven the annual value of illicit on-chain transactions to $154 billion. Countries like Russia, Iran, and North Korea are increasingly using cryptocurrency to bypass traditional banking restrictions. The report highlights the ruble-pegged stablecoin A7A5 as a key tool for Russian entities, facilitating $93.3 billion in transactions and enabling cross-border trade. A7A5, linked to exchanges Grinex and Meer, offers an "instant exchange" service to convert into major USD stablecoins with minimal KYC, processing over $2.2 billion. Iran's Islamic Revolutionary Guard Corps accounts for over 50% of the value received by Iranian services, while North Korea leads in cyber theft, stealing over $2 billion in 2025. Stablecoins represent 84% of illicit transaction volumes.
