Chainlink has announced a landmark partnership with Mastercard aimed at bridging traditional finance and DeFi. The collaboration allows Mastercard’s more than 3 billion cardholders to purchase cryptocurrencies directly onchain, marking a major milestone in the mainstream adoption of digital assets.
Enabled by Chainlink’s secure interoperability infrastructure and Mastercard’s global payments network, the new system simplifies fiat-to-crypto conversions. Key technical and liquidity support is provided by infrastructure partners, including Zerohash, Swapper Finance, Shift4 Payments, and XSwap, while Uniswap handles decentralized trade execution.

“This is exactly the kind of convergence Chainlink was built to support,” said Chainlink Co-founder Sergey Nazarov.
“Through this partnership, we’re connecting a massive user base with real-time, secure access to onchain trading.”
Raj Dhamodharan, Executive Vice President of Blockchain & Digital Assets at Mastercard, echoed that sentiment: “Consumers want seamless access to crypto, and this partnership delivers just that—bridging offchain transactions with the growing onchain economy.”
The end-to-end solution leverages Zerohash for custody, compliance, and instant fiat-to-crypto settlement. Shift4 handles card processing, while Swapper Finance uses XSwap and Uniswap to finalize crypto purchases onchain. The system aims to provide a secure, compliant, and intuitive experience for both novice and experienced users.
“By abstracting away the complexities of crypto transactions, we’re making DeFi accessible to all,”
said Edward Woodford, CEO of Zerohash.
Uniswap Labs’ Drew Turchin added, “This shows how protocols like Uniswap continue to serve as critical infrastructure for innovation in onchain markets.” The service is now live via Swapper Finance at swapper.finance, allowing Mastercard users worldwide to tap into decentralized finance with familiar payment tools.
Meanwhile, Mastercard is continuing to deepen its role in shaping the future of digital payments. In a separate initiative, the company is teaming up with PayPal to streamline both online and in-store checkouts. Central to this effort is Mastercard’s new “One Credential,” a unified digital identity that allows users to manage multiple payment methods from a single, secure platform.
