The ruble-backed stablecoin A7A5 has seen its supply surge past $90 billion, outpacing the growth of major stablecoins USDT and USDC last year. Launched by A7 LLC, linked to Russia's Promsvyazbank and businessman Ilan Shor, A7A5 facilitates cross-border payments for Russian users amid banking restrictions. Despite Western sanctions, the ruble has strengthened over 40% against the U.S. dollar this year, driven by capital controls and central bank actions.
