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.

• Crypto card spending hit $759M/month in July, up 2.5x in a year, from near-zero in Oct 2023.
• The market flipped from 88% euro-stablecoin dominance (EURe/Gnosis) a year ago to dollar stablecoins now leading (USDC 58%, USDT 26%) spread across Optimism, Solana, and Base.
• Volume is still negligible next to traditional card networks' trillions, but Visa's rails are becoming the consolidation point, letting stablecoins piggyback on existing merchant infrastructure with no adoption friction.
