The A7A5 stablecoin, pegged to the Russian ruble, has maintained robust growth in onchain transactions even after Western sanctions sought to restrict its use. According to blockchain security firm CertiK, the stablecoin processed more than $110 billion in cumulative transaction volume and captured around 43% of the global non-US dollar stablecoin market. The number of wallets holding A7A5 nearly doubled over a 15-month period, rising from 13,000 to 29,000.
Issued in early 2025 by Old Vector LLC, a Kyrgyz company acting on behalf of Russian cross-border payment firm A7 LLC, A7A5 operates under a framework recognized by Russian authorities as a digital financial asset. The firm behind A7 LLC is co-owned by Moldovan-Russian oligarch Ilan Shor and Promsvyazbank, a Russian state-owned bank with ties to the defense sector. This connection places the stablecoin at the intersection of official Russian financial infrastructure and cryptoeconomics.
Despite the European Union’s 19th sanctions package explicitly banning transactions involving A7A5 from late 2025, CertiK noted the stablecoin’s reserve structure and issuance mechanisms shield it from direct Western enforcement. Key assets supporting A7A5 are held within Central Asian banking institutions, predominantly in Kyrgyzstan, outside the reach of Western authorities. The stablecoin also leverages decentralized finance (DeFi) liquidity pools on platforms like Curve and Uniswap, enhancing resilience against freezes linked to centralized exchanges.
The stablecoin’s design omits a centralized kill switch, ensuring that wallet and fund freeze controls remain solely with its Russian and Kyrgyz developers. This structural choice limits the ability of international regulators to disrupt its circulation or seize assets. Furthermore, trading volumes remain significant, with reported figures showing $11.2 billion in trades against the Russian ruble and $6.1 billion against the USDT stablecoin, predominantly facilitated through the exchange Grinex. Grinex was developed from Garantex, a platform previously linked to laundering funds connected to notable cybercriminal groups and North Korean hacking operations.
Security concerns surrounding the ecosystem have been highlighted by prior law enforcement actions, including the seizure of Garantex’s domain by the US Secret Service and freezes of tens of millions of USDT tokens. Despite these moves, A7A5’s onchain activity continues unimpeded, challenging the efficacy of sanctions targeting blockchain-based payment systems.
CertiK describes A7A5 as a leading example of a sanctions-evasion stablecoin, underpinned by a combination of strategic reserve placement and decentralized distribution. This model complicates Western attempts to enforce restrictions on illicit financial flows and underscores the limitations faced by regulatory interventions relying on jurisdictional reach over blockchain infrastructure.
