Mastercard and MoonPay have unveiled a strategic partnership aimed at bringing stablecoin payments into the global mainstream.

The collaboration will allow businesses and fintechs to issue Mastercard-branded cards linked directly to users’ stablecoin balances, offering seamless conversion into fiat currency for spending at over 150 million merchant locations worldwide.

At the heart of the initiative is Iron, an API-based stablecoin infrastructure acquired by MoonPay in March. This technology underpins the payment flow, enabling digital asset wallets to operate more like modern digital bank accounts.

By combining Mastercard’s expansive payment network and digital asset experience with MoonPay’s infrastructure, the partnership is designed to create a frictionless bridge between digital asset and traditional financial ecosystems.
