“This is the type of traditional finance and decentralized finance convergence that Chainlink was built to make possible,” said Sergey Nazarov, co-founder of Chainlink. “I’m excited about Chainlink’s ability to enable this critical connection between the traditional payments world and more than 3.5 billion Mastercard cardholders, directly into the next generation trading environments of on-chain decentralized exchanges. It has been great collaborating closely with the Mastercard team on this innovative implementation, as well as the teams at Swapper Finance,, Shift4, zerohash. This was a complex and multilayered collaboration, which I was thrilled to see the Chainlink community help make possible.”
