Mastercard is actively exploring the settlement of card payment flows using Ripple USD (RLUSD) on the XRP Ledger, a move that could directly link one of the world's largest payment networks with XRPL-based stablecoin infrastructure. In a significant development, Christian Rau, Mastercard's Senior Vice President for Digital Assets and Blockchain, confirmed the company is collaborating with Gemini on an RLUSD settlement use case, targeting a live implementation in the first half of 2026.

Mastercard Signals XRP Ledger Stablecoin Use Case

Speaking at an XRPL and Global Digital Finance stablecoin roundtable in Paris, Rau framed the initiative as part of Mastercard’s broader push to integrate stablecoins into existing payment rails rather than treat them as a parallel system. He said the company continues to approach the sector from a “payments first” perspective, arguing that stablecoins have now entered the mainstream of financial services and can improve how money moves across borders and between institutions.

“Over the last 50, 60 years we’ve been constantly innovating on how payments can be safe, simple, secure,” Rau said. “And if you then fast forward to five years back or two years back, you will realize that stablecoins arrived in the financial services mainstream. And we believe that the benefits that they bring in terms of settlement cycles, money moving globally freely, they can definitely add to further driving sustainable innovation in the financial services and payment ecosystem.”

Rather than pitching stablecoins as a replacement for the card model, Rau described them as an additional settlement layer inside Mastercard’s existing network. He pointed to the scale of that network as the core advantage: roughly 150 million acceptance locations and 3.8 billion cards. In Mastercard’s view, plugging stablecoins into that infrastructure offers a more immediate path to adoption than waiting for wallet-to-wallet systems to replace incumbent rails.

“We however believe that the power of the network that we bring in terms of 150 million acceptance location, 3.8 billion cards, plugging in stablecoins into this system is the best of both worlds in that sense,” Rau said. “So think about stablecoins just another settlement currency within our network. That again brings certain benefits that fiat currencies do not allow today.”

The most concrete example he gave was Gemini. Rau said Mastercard is working with the exchange to explore settling Gemini card flows in RLUSD, describing the exchange as one of the firm’s most prominent US crypto partners. “The XRP example is we work with Gemini,” he said. “We explore with them to settle their card flows in RLUSD. So we look at bringing this to life still in the first half of this year and we are very excited about that.”
