Mastercard is experimenting with payments using Ripple and RLUSD.

Ripple, Mastercard, WebBank, and Gemini are collaborating to test stablecoin-based credit card transactions through RLUSD. This test could be one of the first examples of a regulated U.S. bank using a public blockchain and stablecoin to process fiat card payments.

RLUSD has surpassed $1 billion in circulation and is regulated under New York's Trust Act. This development highlights innovation in financial technologies and the potential of stablecoins.
