In 2023, Mastercard, in collaboration with MoonPay, launched payment cards linked to stablecoins like USDC, allowing users to spend their digital balances in over 150 million stores worldwide. These cards automatically convert stablecoins to local currencies at the time of purchase, facilitating everyday transactions. This service is built on a stable infrastructure from Iron, which was acquired by MoonPay in March 2025, converting digital wallets into digital bank accounts. This initiative aims to facilitate financial transfers, cross-border payments, and compensation for freelancers and creators, enhancing the integration of digital currencies into the traditional financial system.
