The financial world is witnessing a pivotal moment in the convergence of traditional payment systems and digital assets. Mastercard and MoonPay have joined forces 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 adoption of cryptocurrency, transforming how individuals and businesses manage and spend digital assets.
Backed by Iron’s robust API infrastructure—acquired by MoonPay in March 2024—the new solution enables enterprises and fintech platforms to issue Mastercard-branded cards directly linked to stablecoin wallets. These cards automatically convert stablecoins into local fiat currency at the point of sale, allowing seamless transactions across Mastercard’s vast global network.
This integration doesn’t just bridge crypto and fiat—it redefines what a digital wallet can do.
Bridging the Gap Between Crypto and Everyday Spending
For years, one of the biggest barriers to crypto adoption has been usability. While blockchain technology offers speed, transparency, and lower fees, spending digital assets in real-world scenarios has remained clunky. That’s where this new partnership steps in.
By leveraging MoonPay’s extensive ecosystem—spanning over 500 platform integrations, including major crypto exchanges and self-custody wallets—Mastercard gains access to a ready-made user base of more than 100 million active crypto users. Of those, 120 million already hold stablecoin balances, and 20 million transact with them monthly.

This massive reach allows the partnership to deliver immediate utility: users can now spend their USDC, DAI, or other stablecoins just like cash—without needing to manually convert funds or rely on third-party exchanges.
For freelancers, gig workers, and global entrepreneurs, this means faster payouts and lower transaction costs. A developer in Nigeria, a designer in Vietnam, or a content creator in Ukraine can receive payments in stablecoins and instantly use them for groceries, bills, or travel—anywhere Mastercard is accepted.
Turning Crypto Wallets Into Full-Service Financial Accounts
At the heart of this transformation is Iron’s API infrastructure, which functions as the engine powering real-time crypto-to-fiat conversions. Previously, crypto wallets were largely limited to storing and transferring digital assets. Now, thanks to Iron’s technology, they’re evolving into full-fledged financial accounts.
Through programmable APIs, neobanks, payroll platforms, and fintech apps can embed instant stablecoin settlement capabilities directly into their services. This enables:
- Instant cross-border salary payments in stablecoins
- Automated merchant settlements
- Real-time disbursements for gig economy platforms
- Seamless fiat off-ramps at point-of-sale
Imagine a ride-sharing app that pays drivers in USDC via a Mastercard-linked wallet. The driver can spend that balance immediately at gas stations, convenience stores, or online retailers—all without leaving the crypto ecosystem until the exact moment of purchase.
Scott Abrahams, Executive Vice President of Global Partnerships at Mastercard, emphasized the strategic importance of this move:
“Our network brings trust, scale, and global reach. Combined with MoonPay’s deep crypto integration, we’re creating a pathway for stablecoins to become part of everyday commerce.”
Driving Financial Inclusion Through Digital Currency
One of the most impactful aspects of this initiative is its potential to expand financial inclusion. In many emerging markets, traditional banking infrastructure is either inaccessible or inefficient. Stablecoins offer a compelling alternative—digital money that’s fast, cheap, and borderless.
With over 150 million acceptance points globally, Mastercard’s network provides unparalleled access. When paired with MoonPay’s user-friendly onboarding tools and Iron’s conversion layer, even unbanked or underbanked populations can participate in the global economy.
For example:
- A small business owner in Indonesia can accept payments in stablecoins and spend them locally using a physical card.
- An NGO can distribute aid in digital dollars that recipients can use immediately—without relying on volatile local currencies.
- Remote workers in Latin America can bypass high remittance fees and receive salaries directly in spendable digital form.
This isn’t just about convenience—it’s about economic empowerment.

Enterprise-Grade Solutions for Fintech Innovation
The partnership isn’t only consumer-focused. Enterprises and fintech developers now have the tools to build innovative financial products on top of this infrastructure.
Using MoonPay’s APIs and Mastercard’s issuing capabilities, companies can:
- Launch branded corporate cards tied to treasury stablecoin holdings
- Offer employees crypto-based expense accounts with automatic fiat conversion
- Integrate instant payout systems for marketplaces and DAOs
For startups building in Web3, this removes one of the biggest operational hurdles: bridging decentralized finance (DeFi) with real-world spending power.
Moreover, because the system operates within regulated frameworks—including KYC/AML compliance and anti-fraud safeguards—it meets enterprise security standards while maintaining crypto-native flexibility.

Which stablecoins are supported?
While specific details are still emerging, leading fiat-backed stablecoins like USDC and DAI are expected to be supported initially. More may be added as the network expands.
Do I need a bank account to use this card?
No. The card is linked directly to your crypto wallet via MoonPay’s infrastructure. As long as you have a supported wallet with stablecoin funds, you can apply and start spending.
