币界网报道：Russian regulators are investigating potential illegal activities involving ruble-backed stablecoins after blockchain analytics firm Crystal identified suspicious transactions linked to sanctioned entities. The stablecoins, issued by multiple Russian platforms, claim 1:1 ruble backing but show patterns of being used to circumvent financial restrictions. Crystal's report highlights transactions moving funds through these tokens to exchanges like Garantex, which faces U.S. and EU sanctions. While Russian officials previously supported stablecoins for cross-border settlements, the Central Bank now warns they may enable sanctions evasion. The probe comes as Russia develops its CBDC, with authorities scrutinizing whether these private stablecoins comply with existing currency controls and anti-money laundering laws.
