Crypto Payment Card Monthly Spending Reaches $759M, Stablecoins Drive Offline Adoption

According to Mars Finance, citing a16z crypto, monthly spending on crypto payment cards has grown from a niche scale to $759 million. These cards allow users to pay with cryptocurrency anywhere traditional card networks are accepted, with stablecoins converted to local currency at the point of sale—making the transaction experience identical to merchants as a regular card swipe. As of July 31, RedotPay has consistently held the majority share of spending across card programs, while EtherFi, KAST, and Karta have gradually increased their market share since late 2025. a16z crypto notes that crypto cardholders do not require traditional bank accounts; they can hold stablecoins with the card issuer or directly via self-custody. These cards expand global access to USD accounts and provide stablecoin holders with a convenient way to spend.
