With the continuous evolution of blockchain technology and the rapid development of the crypto assets market, market participants have been seeking to attract more capital inflows into the crypto assets market. At the same time, there are users who, in addition to using traditional centralized exchanges, also hope to directly complete the conversion from fiat to crypto assets through on-chain methods. However, existing coin purchase paths often involve off-chain payments, cumbersome identification verification, and complex cross-chain operations, which still have certain limitations in terms of user experience, transaction efficiency, and compliance risks. To address this pain point, Chainlink, MasterCard, ZeroHash, Swapper Finance, Shift4 Payments, XSwap, and Uniswap have collaborated to build a closed-loop solution from fiat payment to on-chain asset delivery, aiming to create a safer, more transparent, and convenient on-chain native coin purchase.
