Russian Stablecoin Expansion Raises Security Concerns

The stablecoin security landscape is facing significant threats in 2026, according to a recent threat intelligence report from Skynet. The report highlights two key concerns: sophisticated attacks on cross-chain bridges and the rapid expansion of A7A5, a Russian-ruble-backed stablecoin.

Skynet's report notes that bridge-related incidents have resulted in over $328 million in losses so far this year, with wallet compromise being the dominant exploit vector. The report identifies five expanding attack categories: cross-chain bridge and interoperability protocols, custody and treasury infrastructure, composability risk within DeFi integrations, payment-focused and stablecoin-specific chains, and compliance and identity infrastructure.

A7A5 has emerged as a major player in the stablecoin market, with over $110 billion in cumulative on-chain transactions and 43% of the global non-USD stablecoin market share. Despite being built by sanctioned actors, A7A5's issuer, collateral bank, and transaction platform are all under overlapping US, UK, and EU sanctions designations.
