Mastercard and MoonPay Launch USDC-Powered Payment Cards for 150M Merchants Globally

Mastercard has announced a global rollout of stablecoin-enabled payment cards in partnership with MoonPay, marking a major step toward mainstream crypto adoption. The collaboration utilizes MoonPay’s Iron infrastructure to instantly convert digital assets like USDC to fiat during transactions, removing barriers for both merchants and consumers.

The initiative targets approximately 150 million merchants worldwide, expanding Mastercard’s existing crypto payment solutions. By integrating stablecoins into its card network, Mastercard is bridging traditional finance and digital assets—solving long-standing scalability and usability challenges in crypto commerce.

This strategic MOVE responds to growing institutional demand for blockchain-based settlements. MoonPay’s Iron technology enables real-time conversion, allowing merchants to receive fiat while customers spend crypto—a win-win system that could drive retail adoption. The global deployment highlights Mastercard’s ambition to lead the convergence of Web3 and traditional payment systems.
