Chainlink and Mastercard Partner to Enable Over 3 Billion Cardholders to Purchase Crypto Directly Onchain

Chainlink and Mastercard are connecting the offchain payments world directly to the onchain DeFi world in close partnership with zerohash, Swapper Finance, Shift4 Payments, and XSwap, while leveraging the Uniswap protocol.

SAN FRANCISCO, June 24, 2025 /PRNewswire/ -- Chainlink today announced a new partnership with Mastercard to securely enable payment cardholders worldwide to easily purchase crypto assets directly onchain through a secure fiat-to-crypto conversion. This breakthrough is powered by Chainlink's secure interoperability infrastructure and Mastercard's trusted global payments network, removing long-standing barriers that have kept mainstream users from accessing the onchain economy. zerohash provides the onchain service and liquidity needed to convert fiat into crypto with seamless smart contract execution. Additional integration support comes from Shift4 Payments, Swapper Finance, and XSwap to deliver a next generation app experience, which utilizes the Uniswap protocol.

"This is the type of traditional finance and decentralized finance convergence that Chainlink was built to make possible. I'm excited about Chainlink's ability to enable this critical connection between the traditional payments world and the over three billion cardholders in the Mastercard user base, directly into the next generation trading environments of onchain decentralized exchanges," said Sergey Nazarov, Co-Founder of Chainlink. "It has been great collaborating closely with the Mastercard team on this innovative implementation, as well as the teams at Swapper Finance, XSwap, Shift4, and zerohash, this was a complex and multilayered collaboration, which I was thrilled to see the Chainlink community help make possible."

"There's no doubt about it – people want to be able to easily connect to the digital assets ecosystem, and vice versa. That's why we continue to leverage our proven expertise and global payments network to bridge the gap between onchain commerce and offchain transactions," said Raj Dhamodharan, executive vice president, Blockchain & Digital Assets at Mastercard. "In coming together with Chainlink, we're unlocking a secure and innovative way to revolutionize onchain commerce and drive the broader adoption of crypto assets."

Swapper Finance leverages XSwap, the leading DEX built out of the Chainlink ecosystem that uses the Chainlink standard for data and interoperability, via an integration between zerohash and Shift4 Payments. zerohash provides the core compliance, custody, and transaction infrastructure, making it possible to convert fiat into crypto for smart contract consumption in a regulated manner. Shift4 enables seamless card processing, while XSwap sources liquidity from decentralized exchanges like the Uniswap protocol, enabling the final execution of swaps onchain. Together, these technologies create a unified, compliant, and intuitive user experience that brings crypto access directly to mainstream payment cardholders.

Bringing zerohash, Shift4 Payments, Swapper Finance, and XSwap technologies together with the Chainlink standard and the power of the Mastercard network allows large amounts of previously hard to access value to now be leveraged for executing transactions onchain.

"We are excited to be the infrastructure partner alongside Chainlink and Mastercard on the Swapper Finance platform," said Edward Woodford, CEO & Co-Founder, zerohash. "zerohash's flexible crypto and stablecoin infrastructure powers seamless, compliant crypto-to-crypto swaps. zerohash provides the infrastructure to make access to decentralized exchanges simple through seamless compliant onboarding, abstracting away the complexities of smart contracts and low-latency onchain transactions."

"The Uniswap protocol has become foundational for onchain markets, enabling developers around the world to build new tools for a wide range of users," said Drew Turchin, Head of Business Development at Uniswap Labs. "It's exciting to see this Swapper leverage the protocol and is another great example of how the protocol continues to serve as critical infrastructure in the financial stack."

As adoption of crypto assets continues to grow, collaborations like the one between Mastercard and Chainlink are helping drive a new wave of user-centric solutions that bridge the gap between crypto-native technology and real-world usability.
