In a groundbreaking move that signals the accelerating convergence of traditional finance and digital assets, Mastercard has unveiled a comprehensive end-to-end stablecoin payments system. This new infrastructure enables consumers to spend stablecoins directly from their crypto wallets while allowing merchants to receive payments in stablecoins—seamlessly integrating blockchain-based transactions into the global payments ecosystem.
The announcement, made on April 28, marks a pivotal moment in the evolution of digital finance. With increasing regulatory clarity around stablecoins worldwide, Mastercard is positioning itself at the forefront of a new era where cryptocurrencies are not just speculative assets but practical tools for everyday transactions.
A 360-Degree Approach to Stablecoin Integration
Mastercard describes its initiative as an "integrated, 360-degree approach" to stablecoin adoption. The system leverages strategic partnerships with leading players across the Web3 and fintech landscapes, including OKX, MetaMask, Kraken, Gemini, Bybit, Crypto.com, and Binance. These collaborations are designed to bridge the gap between decentralized finance (DeFi) and mainstream commerce.
Through this network, users can now use stablecoins held in their self-custody wallets to make purchases at over 150 million merchant locations worldwide that accept Mastercard. No longer is it necessary to convert digital assets into fiat currency before spending—transactions occur in real time, with instant settlement enabled by blockchain technology.
Merchants, too, benefit from enhanced flexibility. Working with payment processor Nuvei and stablecoin issuer Circle, businesses can accept USDC (USD Coin) directly, reducing reliance on traditional banking rails and minimizing transaction costs.
“To realize its potential, we need to make it as easy for merchants to receive stablecoin payments and for consumers to use them,” said Jorn Lambert, Chief Product Officer at Mastercard. “Unlocking the potential of stablecoins to streamline payments is core to how we navigate the rapidly changing world.”

Powering Real-Time Transactions: The Multi-Token Network
At the heart of Mastercard’s stablecoin strategy lies the Mastercard Multi-Token Network (MTN)—a secure, scalable infrastructure that supports real-time issuance, transfer, and redemption of tokenized assets. MTN enables partners like Ondo Finance to utilize on-chain financial instruments while maintaining compliance and interoperability.
Notably, major financial institutions including JPMorgan and Standard Chartered are already connected to MTN, underscoring growing institutional confidence in blockchain-based payment systems. By combining the reliability of traditional finance with the speed and transparency of decentralized networks, MTN sets a new standard for cross-border and domestic transactions.
This hybrid model ensures that digital asset transactions meet the same security and fraud prevention standards as conventional card payments—making them viable for mass adoption.
The OKX Partnership: Bridging Digital Finance and Daily Life
One of the most significant collaborations within this ecosystem is between Mastercard and OKX, one of the world’s leading cryptocurrency exchanges. Together, they have launched the OKX Card, a physical and virtual payment card that allows users to spend their crypto holdings directly.
Haider Rafique, Chief Marketing Officer at OKX, emphasized the transformative potential of the partnership:
“Our strategic partnership with Mastercard to launch the OKX Card reflects our commitment to making digital finance more accessible, practical, and relevant to everyday life.”
The card supports direct spending from users’ crypto wallets without requiring prior conversion to fiat. It integrates seamlessly with existing point-of-sale systems, offering a frictionless experience for both consumers and retailers.

MetaMask Launches Self-Custody Metal Payment Card
Also announced on April 28, MetaMask—the popular decentralized wallet—revealed its own innovation: the MetaMask Metal Payment Card, developed in partnership with fintech firms CompoSecure and Baanx. Backed by Mastercard’s global network, this card allows users to spend directly from their self-custody wallets.
Unlike earlier crypto cards that required pre-loading funds or converting assets into fiat, the MetaMask card executes transactions via smart contracts in under five seconds. All activity occurs on the Linea network, a zkEVM Layer 2 blockchain secured by Ethereum, ensuring high throughput and low fees.
Ale Machado, Product Manager at MetaMask, highlighted the significance:
“For too long, crypto users have been locked out of everyday finance. The MetaMask Card changes that. It allows millions of users worldwide to finally bridge the gap between the blockchain and the real world without sacrificing control or security.”
While currently available only in select countries and via a waiting list, the rollout represents a major step toward mainstream adoption of self-custodied digital assets.
