Bitcoin application layer project Citrea, supported by Founders Fund and Galaxy Ventures, has launched its native stablecoin, ctUSD. Issued by MoonPay and backed by M0, ctUSD is fully collateralized by short-term U.S. Treasuries and cash. The stablecoin aligns with the upcoming GENIUS Act regulatory framework for stablecoins. Citrea aims to provide a unified, compliant dollar settlement layer for Bitcoin-denominated markets, addressing the current passive storage of over $1 trillion in Bitcoin.
