Connecting bank cards to on-chain payments – the Mastercard and Chainlink partnership and $3.1T in Digital Transactions on the Horizon. Payment giants have introduced an infrastructure that promises users access to on-chain assets directly with credit and debit cards. The architecture is implemented on Swapper Finance: the XSwap front end, Shifd Payments for card processing, and Zerohash for compliance custody.

Architecture of the Mastercard and Chainlink Solution
I must note that the technical component is quite promising. The user initiates a token purchase in the Swapper Finance front end, entering Mastercard card data. The request goes through standard card processing, after which, through the platform’s back-end module, the transaction is routed to the decentralized exchange XSwap. At the settlement stage, Chainlink, using its secure interoperability layer (CCIP), transmits messages and price data between system components, which makes it possible to execute the swap without manual interaction with smart contracts. Compliance, custody, and fiat onboarding are provided by Zerohash, whereas Shifd Payments is responsible for the regulated processing of card transactions.
Overcoming Scaling Barriers and Market Potential
Chainlink refers to McKinsey, which forecasts that global digital-payments revenue will grow to $3.1 trillion by 2028. However, even with 560 million crypto-owners, most users interact with the blockchain only for trading. The main obstacles are quite classical: the absence of convenient Web3 interfaces and weak integration with familiar payment instruments. The Mastercard–Chainlink infrastructure solves both problems: the familiar bank-card UX reduces friction for retail users, and the oracle layer of Chainlink provides institutional settlement reliability. Such a direct bridge between TradFi and DeFi can potentially multiply on-chain liquidity and accelerate the adoption of blockchain payments in remittances, micropayments, and subscription segments.
Raj Dhamodharan, Executive Vice President, Blockchain & Digital Assets, Mastercard:
“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 on-chain and off-chain transactions. In coming together with Chainlink, we’re unlocking a secure and innovative way to revolutionize on-chain commerce and drive the broader adoption of crypto assets.”
Edward Woodford, CEO & Co-Founder, Zerohash:
“We are excited to be the infrastructure partner alongside Chainlink and Mastercard on the Swapper Finance platform. 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 on-chain transactions.”

Conclusion
Chainlink continues to carry out its mission of bridging the gap between fragmented DeFi and TradFi. And they are doing this more thoroughly and intensively than anyone else, entering into ever more promising partnerships. I would keep an eye on Chainlink, which is occupying an increasingly large place in the very infrastructure of future digital payments.
