Chainlink Partners With Mastercard to Bring Crypto Access to Cardholders
Chainlink has announced a major partnership with Mastercard, enabling global payment cardholders to purchase crypto assets directly onchain.
The integration bridges traditional finance with decentralized finance through secure fiat-to-crypto conversions using Chainlink’s interoperability infrastructure and Mastercard’s trusted payments network.
The collaboration includes support from zerohash, which supplies the liquidity and compliance infrastructure for converting fiat into crypto. Swapper Finance, XSwap, and Shift4 Payments are also part of the ecosystem powering this next-generation app experience, which taps into the Uniswap protocol for decentralized liquidity.
“This is the type of TradFi-DeFi convergence Chainlink was built for,” said Sergey Nazarov, Co-Founder of Chainlink. He emphasized the ability to connect Mastercard’s over three billion cardholders to decentralized exchanges and onchain trading environments. Nazarov praised the complexity and coordination of the integration, crediting the Chainlink community and partner teams.
Mastercard also highlighted the increasing demand for seamless digital asset access. “People want to connect to the digital assets ecosystem,” said Raj Dhamodharan, Executive Vice President of Blockchain & Digital Assets at Mastercard. “By joining forces with Chainlink, we’re unlocking secure and innovative ways to drive mainstream adoption of crypto assets.”
The integrated solution features zerohash as the backbone for compliance, custody, and conversion. Shift4 handles card processing, while XSwap sources liquidity across decentralized exchanges using Chainlink’s standards. Swapper Finance provides the user interface that ties these elements together into an intuitive, regulated product.
By combining the capabilities of Chainlink, Mastercard, zerohash, and supporting platforms, the partnership removes long-standing barriers to crypto adoption. It allows cardholders to interact with decentralized finance apps securely and directly, marking a milestone in onchain commerce.
