From swiping cards to buying coins on the blockchain, in between are Shift4, Zero Hash, Swapper Finance, and Uniswap—these names alone make me hungry, but they indeed build the bridge from fiat to DeFi. Mastercard's infrastructure investments this time are quite solid.

CryptoWorld News reports, citing financefeeds, that Mastercard has partnered with Chainlink to build a fiat-to-crypto asset channel for cardholders, enabling users to directly buy digital assets in on-chain smart contracts via their bank cards. The scheme is handled for card transactions by Shift4 Payments, with Zero Hash responsible for compliance, clearing, and settlement, Chainlink providing data and interoperability infrastructure, and Swapper Finance obtaining liquidity and executing on-chain swaps via Xswap from decentralized exchanges such as Uniswap.
