The collaboration has been secured in close partnership with Zerohash, Swapper Finance, Shift4 Payments, and XSwap using the Uniswap protocol. Zerohash provides the on-chain service and liquidity required to convert fiat into crypto with seamless smart contract execution. Chainlink operates on a trusted interoperability infrastructure, while Mastercard is a trusted global payment network that blends to offer mainstream users access to the on-chain economy.

The partnership gears toward converging TradFi with the DeFi world

Sergey Nazarov, Co-Founder of Chainlink, said that the partnership was a type of traditional finance and decentralized finance convergence that Chainlink was built to make possible. He was excited about Chainlink’s ability to enable the critical connection between the conventional payment world and the over three billion cardholders in the Mastercard user base into environments of on-chain decentralized exchanges.

Nazarov acknowledged it was great connecting with the Mastercard team on the innovative implementation with Swapper Finance, XSwap, Shift4, and Zerohash. He added that it was a complex and multilayered collaboration, which he was excited to see Chainlink make happen.

Raj Dhamodharan, vice president of Blockchain and Digital Assets at Mastercard, noted that there was zero doubt that people wanted to connect to the digital assets ecosystem easily. He added that Mastercard is tapping into its proven expertise and global payment network to close the gap between on-chain commerce and off-chain transactions. He revealed that the partnership with Chainlink unlocks a secure and innovative way to revolutionize on-chain commerce and drive the broader adoption of crypto assets. 

Zerohash will provide the core compliance, custody, and transaction infrastructure to allow conversion of fiat to crypto in a regulated manner. Shift4 will enable card processing, while XSwap sources liquidity from decentralized exchanges such as the Uniswap protocol, supporting final execution of swaps on-chain. The collaboration of the technologies makes a unified, compliant, and seamless user experience while bringing crypto assets access to payment cardholders. 

During a fireside chat at Blokworks’ Digital Asset Summit in April, Chainlink co-founder Sergey Nazarov sat with Guy Young, Ethena Labs Founder, to discuss the convergence of TradFi and DeFi via stablecoins and real-world assets.

Nazarov agreed that DeFi and TradFi will eventually converge by combining DeFi’s superior distribution channel with TradFi’s risk management and custody guarantees. He added that the increasing adoption of blockchain will ultimately kill the distinction between private and public chains. Young revealed that bringing institutions on-chain is an inevitable yet long-term goal. He added that disappointment may present with the speed at which the shift will occur. 

The collaboration helps to drive user-centric solutions 

Edward Woodford, CEO and CO-Founder of Zerohash, revealed his excitement for Zerohash being the infrastructure partner alongside Chainlink and Mastercard on the Swapper Finance platform. He said Zerohash is a flexible crypto and stablecoin infrastructure that powers compliant crypto-to-crypto swaps. According to Woodfird, the company offers simple access to decentralized exchanges through seamless, compliant onboarding, removing the complexities of smart contracts and low-latency on-chain transactions.

Drew Turchin, Head of Business Development at Uniswap Labs, said that the Uniswap protocol has become the foundation for on-chain markets, enabling developers worldwide to build new tools for a wide range of users. He was excited to see Swapper Finance use the protocol and shared it as an example of how it continues to serve as critical infrastructure in the financial stack. 

According to Chainlink, collaboration helps drive a new wave of user-centric solutions that bridge the gap between crypto-native technology and real-world usability.  The Swapper Finance platform is now live and available for users to transact.
