The financial world is witnessing a pivotal moment in the convergence of traditional payment systems and digital assets. Mastercard has joined forces with MoonPay to launch a groundbreaking initiative: stablecoin-powered Mastercard cards that can be used at over 150 million merchants worldwide. This collaboration marks a significant leap toward mainstream crypto adoption, enabling seamless spending of stablecoins through one of the most trusted global payment networks.
Backed by Iron’s robust API infrastructure—acquired by MoonPay in March 2024—the new solution allows enterprises, fintechs, and platforms to issue Mastercard-branded cards directly linked to users’ stablecoin wallets. Every transaction automatically converts stablecoins into local fiat currency at the point of sale, eliminating complexity for both consumers and merchants.
This isn’t just about convenience—it’s about redefining what digital wallets can do. With this integration, crypto wallets are no longer siloed tools for trading or holding digital assets. They’re evolving into full-fledged financial accounts capable of powering everyday purchases, global payouts, and real-time cross-border settlements.

Bridging the Gap Between Crypto and Traditional Finance
At the heart of this innovation is a shared vision: making stablecoins as easy to spend as traditional money. While cryptocurrencies have long promised financial inclusivity and faster transactions, usability has remained a barrier. That’s where Mastercard and MoonPay step in.
By combining Mastercard’s vast merchant network and regulatory expertise with MoonPay’s deep crypto integrations—spanning more than 500 wallets, exchanges, and platforms—the partnership creates a powerful bridge between blockchain and real-world commerce.
With over 100 million active crypto users in MoonPay’s ecosystem and an estimated 120 million people holding stablecoin balances, the demand for utility-driven crypto products is clear. Now, those users can turn their digital holdings into immediate purchasing power—without needing to manually convert funds or rely on third-party exchanges.
Scott Abrahams, Executive Vice President of Global Partnerships at Mastercard, emphasized the transformative potential: “This collaboration brings together the trust and scale of Mastercard with MoonPay’s innovative crypto infrastructure to unlock practical, everyday use cases for digital assets.”
How It Works: From Stablecoin to Seamless Spending
The process is simple but revolutionary:
- A user holds USDC, USDT, or another supported stablecoin in their digital wallet.
- That wallet is linked to a Mastercard issued through a participating platform (such as a neobank or fintech app).
- When the user makes a purchase—at a grocery store in Tokyo, an online retailer in Berlin, or a rideshare in São Paulo—the system instantly converts the required amount of stablecoins into local fiat.
- The transaction clears via Mastercard’s network, just like any standard card payment.
Behind the scenes, Iron’s API infrastructure enables this entire flow. It transforms basic crypto wallets into dynamic financial accounts, offering features like:
- Real-time disbursements
- Gig economy payouts
- Merchant settlements
- Automated compliance and reporting
For businesses, this means reduced friction in global payroll, faster vendor payments, and lower transaction fees compared to legacy banking rails.

Expanding Financial Inclusion Worldwide
One of the most impactful aspects of this initiative is its potential to serve underbanked populations. In regions where access to traditional banking is limited—such as parts of Southeast Asia, Africa, and Eastern Europe—stablecoin-backed cards offer a viable alternative.
Freelancers, content creators, and remote workers can now receive direct payouts in stablecoins and spend them instantly using their Mastercard. No need for slow international wire transfers or high conversion fees. No dependency on local banks that may lack infrastructure or impose strict requirements.
Consider a graphic designer in Vietnam receiving payment from a client in Canada. Instead of waiting days for a bank transfer or losing value to exchange fees, they get paid in USDC within minutes. Then, using their MoonPay-issued Mastercard, they can pay bills, buy groceries, or withdraw cash locally—all with near-instant settlement and minimal cost.
This level of accessibility aligns perfectly with the core promise of blockchain: democratizing finance.
Driving Adoption Through Utility
As Ivan Soto-Wright, CEO of MoonPay, noted, the focus is shifting from speculation to utility. “We’re moving beyond crypto as an investment asset,” he said. “This partnership is about building products people use every day—products that solve real problems.”
That shift is critical for long-term adoption. While price volatility once deterred mainstream users, stablecoins offer price stability by being pegged to fiat currencies like the U.S. dollar. When paired with a globally accepted payment network like Mastercard, they become powerful tools for daily financial activity.
Enterprises across industries—from remittance services to gig platforms—are already exploring how to leverage this technology. The ability to programmatically issue cards, manage balances, and automate conversions via APIs opens new doors for innovation in payroll, rewards programs, and embedded finance.
