Mastercard to Enable 150M Businesses to Accept Stablecoin with MoonPay

Mastercard has announced a partnership with MoonPay to facilitate global stablecoin payments. The collaboration enables the rapid integration of stablecoin payments through MoonPay’s Iron technology, using virtual Mastercard cards.

The Iron technology offers an API that allows merchants and fintech companies to efficiently add stablecoin payment options. Through this partnership, over 150 million businesses could accept stablecoin payments, strengthening Mastercard’s position in the digital asset space.

MoonPay, acquired by Mastercard in early 2025, aims to accelerate stablecoin adoption by making crypto payments as seamless as traditional card transactions. Currently, the stablecoin market is valued at $245 billion, with transfer volumes in 2024 exceeding $27.6 trillion—surpassing combined Visa and Mastercard transactions.

On the legislative front, the US Congress is reviewing two bills aimed at regulating the stablecoin market. Although legal clarity remains uncertain, the trend suggests growing institutional acceptance of stablecoins.
