Ripple's regulated stablecoin, RLUSD, has been launched in tokenized US Treasury markets through a strategic partnership with Securitize. This integration involves BlackRock's BUIDL and VanEck's VBILL funds, offering 24/7 liquidity, atomic settlement, and instant transfers. RLUSD, issued under a New York DFS trust charter, is backed by USD deposits and short-term treasuries, with a current circulation of approximately $740 million. Securitize CEO Carlos Domingo emphasized this partnership as a significant move towards integrating real-world assets into decentralized finance (DeFi).
