Swapper Finance has introduced a groundbreaking feature allowing users to deposit funds into decentralized finance (DeFi) applications using traditional bank cards, in partnership with Mastercard and Chainlink. This initiative marks the first instance of purchasing on-chain assets directly with bank cards, facilitated by XSwap and integrated with zerohash and Shift4 Payments. The service leverages Mastercard's extensive payment network and fraud protection, connecting 3.5 billion cardholders to the DeFi ecosystem. Users can now seamlessly buy on-chain assets on decentralized exchanges such as Uniswap through secure fiat-to-crypto transactions. Initial partners for this service include Pi Squared, Stakelink, KyberSwap, AITECH, and Radiant Capital. Swapper Finance's CTO, Arthur, emphasized that this feature will drive Web3's evolution from speculative activities to practical applications, integrating billions of cardholders into the on-chain economy.
