#MastercardStablecoinCards Mastercard's acceleration towards stablecoin cards, announced in April 2025 and expanded with MoonPay in May, signals a bold step towards the mainstream adoption of crypto payments. With partnerships such as OKX and Nuvei, these cards enable users to spend stablecoins at over 150 million merchants worldwide, leveraging a stablecoin transaction volume of $35 trillion (February 2024 – February 2025). Regulatory clarity, such as US rulings excluding certain stablecoins from the securities category, is contributing to this growth. While competition with Visa intensifies, Mastercard's network of over one billion cards allows it to shape a future where stablecoins are organically integrated into everyday transactions, potentially redefining digital payments.
