Russian ruble-based stablecoins A7 and A5 now represent approximately 43% of the global non-USD stablecoin market, according to CertiK's "2026 Stablecoin Threat Report." Since their launch in 2025, these stablecoins have achieved over $110 billion in transaction volume, highlighting their significant role in cross-border settlements. The report also underscores the dual challenges of technological security and regulatory compliance facing the stablecoin ecosystem. Notably, cross-chain bridge-related security incidents have resulted in over $328 million in losses this year, with the Kelp DAO wallet breach accounting for $291 million. CertiK emphasizes that stablecoin risks have expanded beyond smart contract vulnerabilities to include financial infrastructure and geopolitical concerns, posing new challenges for global financial risk management.
