Partnerships Enhance Crypto Accessibility for Credit Card Users
A surge of collaborations is simplifying the process for everyday credit card users to engage in on-chain cryptocurrency purchases and utilize their crypto through bank cards. As the crypto landscape evolves, on-chain platforms are striving to connect conventional payment systems with decentralized finance (DeFi) solutions, while credit card firms continue to forge alliances within the crypto space.
On June 24, Mastercard announced a partnership with Chainlink, a decentralized blockchain oracle network, aimed at enabling Mastercard users to buy cryptocurrencies directly on-chain. This initiative is projected to benefit more than 3 billion Mastercard cardholders, according to an official announcement. The on-chain functionality will be facilitated by zerohash, an infrastructure provider formerly known as Seed CX, which successfully secured $105 million in its Series D funding round in 2022, as reported by Pitchbook. Other entities, including Swapper Finance, Shift4 Payments, XSwap, and the Uniswap protocol, are also involved in this integration.
Chainlink’s co-founder, Sergey Nazarov, elaborated on the integration’s significance, stating that it fosters interoperability between Mastercard, decentralized exchanges (DEXs) like Uniswap, and other participants, thereby establishing essential connectivity and coordination. He noted that this collaboration exemplifies how prominent payment and technology firms like Mastercard are increasingly introducing mainstream audiences to the world of cryptocurrency.
Nazarov emphasized that true mainstream adoption occurs when individuals can leverage existing tools, such as credit cards, to engage with DeFi and conduct on-chain transactions. He expressed enthusiasm about Chainlink’s role in bridging traditional payment systems with the expansive Mastercard user base, leading them into the innovative realm of decentralized exchanges.
Shifting Focus from Crypto Cards to Broader Integration
The collaboration between Mastercard and Chainlink highlights a significant movement towards merging fiat currency and traditional finance (TradFi) with DeFi, with a particular emphasis on simplifying access to web3 for a wider audience. Historically, such integrations have leaned towards enabling crypto holders to spend their digital currencies as fiat through crypto-backed debit or credit cards.
In a recent example of this trend, Mastercard partnered with prominent centralized crypto exchange Kraken to introduce crypto debit cards for users in the UK and Europe. As of March 2025, Mastercard reported total assets of $48.47 billion, reflecting a year-over-year increase of 13.77%, according to Macrotrends. Kraken’s co-CEO, David Ripley, remarked on the transformative potential of crypto in the payments sector, envisioning a future where global commerce and daily transactions are fueled by crypto assets.
Additionally, just two weeks ago, cryptocurrency exchange Coinbase unveiled plans to launch the Coinbase One Card in partnership with American Express later this year, offering up to 4% back in Bitcoin on purchases. Furthermore, the Gemini Credit Card, another Mastercard collaboration, was introduced as early as 2021.
The merging of cryptocurrency with traditional payment methods comes amid growing legislative support for digital assets, as lawmakers seek to establish clearer regulations for the crypto industry. Recently, the U.S. Senate passed the GENIUS Act, focused on stablecoins, with a vote of 68–30. This legislation permits both banks and non-bank entities to issue stablecoins, which currently have a market capitalization nearing $253 billion, according to DeFiLlama.
