Cardstack, a blockchain-powered open-source protocol, today announced it will be integrating Chainlink into Card Pay — a consumer-facing crypto payment and reward platform. Cardstack will use Chainlink Price Feeds to establish accurate and tamper-proof exchange rates on the platform, beginning on the xDAI chain; but with a planned expansion to other blockchains and layer-2 solutions.
Most DeFi price feeds today are used for trading and financial product use-cases, focusing on the needs of investors, token holders, or market makers. Yet, as crypto gains more mainstream attention; especially due to the many scalability solutions being made possible by layer 2 and other blockchain innovations, payment use-cases are becoming increasingly important.
