Crypto Cards Drive $759M Stablecoin Spend, USDC Leads
Crypto payment cards are emerging as a significant driver for stablecoin adoption, with monthly transaction volumes soaring to $759 million in July 2026, according to Paymentscan data. That’s a 2.5x increase from $306 million a year earlier and a sharp rise from less than $1 million when tracking began in October 2023.
These cards allow users to spend stablecoins like USDC and USDT through existing Visa and Mastercard networks. While merchants receive payments in fiat currency, cardholders fund purchases using stablecoins held either on-chain in self-custodial wallets or with card issuers. Nearly 9 million purchases were made with crypto cards in July, averaging $86 per transaction.
USDC Takes the Lead
Dollar-backed stablecoins now dominate crypto card spending. USDC accounted for 58% of July’s volume, while USDT handled 26%. This marks a significant shift from early 2024, when euro-backed stablecoins like EURe controlled 88% of the market. Today, EURe’s share has dwindled to just 2%.
The rise of USDC aligns with broader trends in the stablecoin market. USDC’s stability—trading near its $1 peg—and its integration into payment card programs have made it a preferred choice for global transactions. USDT remains a strong player, backed by its massive market cap of $183.8 billion as of early August 2026.
Expanding Blockchain Footprint
Initially, crypto card spending was heavily concentrated on Gnosis Chain, which powered the first Visa card linked to a self-custodial wallet. Over time, the ecosystem has diversified. As of July, Ethereum Layer 2 Optimism handles 29% of crypto card volume, with Solana and Base each capturing 19%. Gnosis has dropped to a mere 2%, reflecting the proliferation of new card programs and blockchain networks.
Visa Leads the Charge
The majority of crypto card activity occurs through Visa, which operates over 130 stablecoin-linked card programs across 50+ countries. That number is expected to double by the end of 2026. Meanwhile, Mastercard is expanding its settlement capabilities to include regulated stablecoins, enabling faster and more efficient cross-border transactions.
These programs position stablecoins as a back-end infrastructure layer rather than a direct replacement for traditional payment processors. By integrating stablecoins into card issuance, treasury management, and cross-border liquidity, Visa and Mastercard are embedding blockchain technology into their global networks without disrupting the merchant experience.
Market Implications
While $759 million in monthly crypto card volume pales in comparison to the trillions processed by traditional networks, the growth trajectory is clear. Stablecoins, with a total market cap of approximately $316 billion, are becoming a cornerstone of the global financial system. The ability to spend stablecoins seamlessly through crypto cards lowers barriers to entry for unbanked populations and facilitates dollar access in regions with volatile local currencies.
For traders, the rise of stablecoin-powered cards underscores the importance of monitoring liquidity flows in tokens like USDC and USDT. These assets are increasingly viewed not just as trading tools but as functional currencies for real-world transactions. As adoption grows, stablecoin demand could influence market dynamics, particularly during periods of macroeconomic uncertainty or regulatory shifts.
