Crypto Card Payments Surge to $759M Monthly, a16z Survey Shows

Monthly payment volume on crypto payment cards has climbed to more than $759 million, with RedotPay holding the largest share among major crypto cards as of July 31, according to a recent a16z crypto survey. The survey also found that since late last year, Ether.fi (ETHFI), KAST and Karta have steadily expanded their market share.

How Crypto Cards Work

a16z crypto said crypto card users can make offline payments by depositing stablecoins with an issuer or using self-custodied stablecoins without a bank account. The firm said such services are expanding global users’ access to U.S. dollars while improving spending convenience for stablecoin holders.

These cards bridge the gap between digital assets and everyday commerce, allowing holders to spend their crypto at millions of merchants that accept traditional card networks. The growth in monthly volume reflects increasing adoption of stablecoins as a medium of exchange, not just a store of value.

Market Dynamics and Key Players

RedotPay’s leading position underscores the demand for crypto cards that offer seamless conversion of stablecoins to fiat at the point of sale. Meanwhile, the rising share of Ether.fi, KAST, and Karta indicates a more competitive landscape, with providers differentiating through rewards, lower fees, and multi-chain support.

The survey’s findings align with broader industry trends: stablecoin transaction volumes have surged over the past year, and payment infrastructure is evolving to support real-time settlements. For consumers in regions with limited banking access, crypto cards offer an alternative to traditional financial services.

Implications for Stablecoin Adoption

The expansion of crypto card services is significant for stablecoin adoption because it directly links digital dollars to physical-world spending. This utility is critical for moving stablecoins beyond trading and into everyday use, which could drive further regulatory attention and institutional participation.

However, challenges remain, including regulatory uncertainty in some jurisdictions, volatility in crypto markets, and the need for robust compliance measures. The a16z survey highlights the growing maturity of the crypto payments ecosystem, but also signals that scalability and user trust will be key to sustaining growth.

Conclusion

The rise in monthly crypto card payments to $759 million, with RedotPay leading, marks a notable milestone in the integration of digital assets into mainstream finance. As more players like Ether.fi, KAST, and Karta gain ground, the market is poised for further innovation and expansion. For stablecoin holders, these cards offer a practical bridge to everyday spending, underscoring the transformative potential of blockchain-based payments.
