最新报道:The U.S. Treasury's OFAC sanctioned Russian-linked crypto entities including Garantex, its successor Grinex, and ruble-backed stablecoin A7A5 for facilitating sanctions evasion. Garantex processed over $100M in illicit transactions before being shut down in March, while Grinex continued operations using A7A5 tokens issued by Kyrgyz firm Old Vector. The stablecoin, backed by sanctioned Russian bank PSB, processed $1B daily by July according to Elliptic. OFAC blacklisted Old Vector, A7 LLC, Garantex executives, and associated crypto addresses, blocking them from dollar transactions. Treasury officials warned such crypto channels threaten national security by enabling ransomware and sanctions evasion. Chainalysis noted A7A5's $51B transaction volume demonstrates Russia's growing use of crypto payment alternatives.
