Crypto payment cards—which let people spend stablecoins anywhere Visa is accepted—have grown 2.5x in a year to $759 million in monthly volume. The market has shifted decisively toward dollar-backed stablecoins like USDC and USDT, away from euro-backed alternatives, with spending spread across multiple blockchains led by Optimism and Solana. While still tiny compared to traditional card networks, the trend reflects growing mainstream adoption of stablecoins for everyday transactions.
