Stablecoin payment cards recorded their strongest month in August, with spending reaching $1.076 billion for a second straight month above $1 billion. Transactions rose to about 10.67 million and addresses exceeded 283,000, up from 261,000 in July, producing an average purchase size of $100.80. RedotPay processed about $390.1 million, or 36% of sector volume, and accounted for more than 6.34 million transactions, or 54%, implying an average purchase of about $61.50. EtherFi and KAST ranked second and third by monthly volume. Growth was concentrated in emerging markets, while lower transaction costs and expanding stablecoin settlement infrastructure helped make smaller card purchases viable. Mastercard activated stablecoin settlement on June 3 for USDC, Paxos-issued tokens, RLUSD and SoFiUSD across eight chains, and Visa says more than 160 stablecoin card programs are live or in development. The data has significant limitations: three programs generated 55.6% of volume, RedotPay’s Paymentscan figures are self-reported, and the company faces a roughly $472.8 million Hong Kong claim from Binance affiliates over alleged user diversion. RedotPay’s planned $1 billion U.S. listing now appears unlikely before 2027. August’s volume annualizes to about $12.9 billion, only around 0.06% of the $20 trillion-plus traditional card market. At the same time, stablecoin supply fell 3.6% from its May peak, suggesting card users may increasingly be funding balances for spending rather than holding excess capital in the system.
