According to the Ondo Finance announcement, Mastercard has integrated Ondo Finance into its Multi-Token Network (MTN), becoming the first real-world asset (RWA) provider on the network. Ondo's Short-Term US Treasury Fund (OUSG) will be the first tokenized RWA solution on MTN, enabling businesses to access daily gains and flexible cash management services on-chain. The integration allows MTN enterprise users to access OUSG directly on the public blockchain and settle through traditional banking channels without the need for additional crypto infrastructure. OUSG is backed by BlackRock's BUIDL fund and institutions such as Franklin Templeton and WisdomTree, providing stability and liquidity.
