How Russia's A7A5 Stablecoin Helped Evade Sanctions: Tracking a $100 Billion Phenomenon

Since Russia’s invasion of Ukraine triggered sweeping Western sanctions in 2022, Moscow has increasingly turned to cryptocurrency as a lifeline for cross-border transactions. While Tether’s USDT has garnered significant attention for its role in sanctions circumvention, a less-publicized but equally revealing story centers on A7A5—a ruble-pegged stablecoin that has quietly facilitated over $100 billion in transaction volume to evade traditional financial restrictions.

According to blockchain analysis firm Elliptic’s January 22 report, the scale of A7A5 activity has been substantial. In less than a year, the stablecoin processed roughly 250,000 transfers across more than 41,000 wallet addresses, demonstrating widespread adoption within Russia’s crypto infrastructure. The data painted a portrait of Russia’s determined efforts to maintain economic continuity despite international financial isolation.

The Bridge Architecture: How A7A5 Connects Rubles to USDT

Elliptic’s monitoring capabilities revealed the mechanics behind A7A5’s utility. Issued on public blockchains—Ethereum and Tron—the stablecoin operates primarily as a gateway connecting rubles to USDT, enabling Russian entities to convert local currency into dollars without accessing Western banking channels. The exchange volume data underscores this bridging function: A7A5/ruble pairings accounted for $11.2 billion in trading, while A7A5/USDT pairings generated $6.1 billion, totaling $17.3 billion in combined volume.

This architectural arrangement proved ingenious for sanctions evasion purposes. Rather than requiring direct ruble-to-dollar conversions through monitored banking corridors, Russian participants could route transactions through the decentralized stablecoin network. The holder base expanded significantly from 14,000 accounts in July 2025 to 35,500 by the time of Elliptic’s report, signaling accelerating adoption.

Daily Transaction Momentum Collapses Amid Sanctions Pressure

Despite impressive cumulative statistics, more recent trends tell a different story. Daily transaction volumes have plummeted from peak levels exceeding $1.5 billion per day in 2025 to approximately $500 million daily in 2026—a collapse of roughly two-thirds. This sharp deceleration coincides directly with intensified U.S., UK, and EU sanctions targeting Russian-linked crypto infrastructure.

The evidence of stalling demand is unmistakable. Elliptic noted that no significant new A7A5 issuances have occurred since late July 2025. The total circulating supply sits at just over 42.5 billion tokens, valued at roughly $547 million—a relatively modest figure given the historical transaction throughput. This supply stagnation contrasts sharply with the earlier period of vigorous growth, suggesting that Western enforcement measures have effectively dampened new participation.

Sanctions Architecture Effectively Constrains A7A5 Growth

The mechanics of why sanctions have proven effective deserve closer examination. While A7A5’s structure on decentralized blockchains theoretically permits greater censorship resistance than traditional finance, the stablecoin’s issuer retains centralized control through address-level blacklisting capabilities. This design flaw—or feature, depending on perspective—has become A7A5’s vulnerability.

Elliptic collaborated with Tether and the U.S. Secret Service in March 2025 to freeze USDT holdings associated with the sanctioned Russian exchange Garantex, establishing a precedent for enforcement coordination. More recently, Elliptic documented that numerous Russian entities have been sanctioned by U.S. and EU authorities specifically for facilitating sanctions evasion through cryptocurrency, including stablecoin infrastructure. These designations have created a chilling effect on participation.

Growing Isolation from the Broader Crypto Ecosystem

Perhaps most significantly, A7A5 faces progressive disconnection from the wider cryptocurrency infrastructure. Despite Russia’s broader crypto adoption—estimated at 20 million users with $376 billion in crypto received over the past 12 months—A7A5 has become increasingly insular. Its limited utility outside the ruble-USDT corridor reduces incentives for global market makers to maintain robust liquidity pools or integration points.

This isolation reflects a fundamental constraint on sanctions evasion strategies: even as Russian entities remain active cryptocurrency users, the targeted nature of Western enforcement has made certain assets (and the stablecoins pegged to Russian currency) strategic liabilities rather than assets. A7A5 remains a functional tool for domestic-to-offshore ruble conversion, yet it no longer represents a gateway into the broader decentralized finance ecosystem.

The A7A5 case study ultimately demonstrates both the ingenuity and the limits of cryptocurrency-based sanctions evasion. While blockchain technology enables new transaction pathways, centralized control mechanisms embedded within stablecoin architecture create regulatory chokepoints that authorities have proven capable of exploiting.
