According to Cas Abbé, Ethena Labs’ USDe reached 10 billion in circulating supply in roughly 500 days, which he describes as the fastest stablecoin to hit that milestone, source: Cas Abbé on X, Aug 10, 2025. He attributes the acceleration to approval of the GENIUS Act, which he says prohibits issuers from paying yields on stablecoins, source: Cas Abbé on X, Aug 10, 2025.
