The crypto payment card market is undergoing a profound structural transformation. According to the latest report from a16z crypto, as of July 2026, US dollar stablecoins USDC and USDT together account for approximately 84% of crypto payment card spending, with USDC representing 58% and USDT 26%. This marks a reversal from the early 2024 landscape, when euro-backed stablecoin EURe dominated the market—at that time, EURe made up about 88% of card transaction volume, but its share has now plummeted to around 2%.

This shift is no accident. Crypto payment cards allow users to spend stablecoins or crypto assets at any merchant operating under major card networks. At checkout, stablecoins are automatically converted to local currency, so merchants see only a standard card transaction. With traditional payment networks like Visa and Mastercard deeply involved, crypto payments are moving from experimental use cases into mainstream daily spending.
Monthly Transaction Volume Surpasses $759 Million
On the data front, crypto payment cards are seeing clear and robust growth. In July 2026, monthly transaction volume reached $759 million, up roughly 2.5 times from $306 million a year earlier. Looking back to October 2023, when tracking began, monthly volume was less than $1 million. This exponential growth signals a commercial inflection point for the sector.

During the same period, cardholders completed nearly 9 million transactions, up from about 5.2 million a year earlier, with an average transaction value of roughly $86. This ticket size suggests crypto payment cards are no longer limited to niche testing by crypto-native users—they are steadily penetrating everyday payment scenarios for regular consumers.
From a settlement chain perspective, the underlying infrastructure of the payment card market has also been reshuffled. In early 2024, crypto payment card spending was highly concentrated on the Gnosis chain, which powered Gnosis Pay—the first Visa co-branded card directly connected to self-custody wallets. As new card projects launched, settlement chain distribution diversified: Optimism now accounts for about 29% of total card transaction volume, Solana and Base each hold roughly 19%, while Gnosis’s share has dropped to about 2%.
Why Dollar Stablecoins Lead
Dollar stablecoins have prevailed due to three structural factors.
First, the established advantage of the US dollar as a global settlement currency cannot be overlooked. The dollar remains the primary settlement currency for international trade, the main unit of account in global financial markets, and the dominant trading unit in crypto markets. Against this macro backdrop, stablecoin payments naturally gravitate toward dollar assets, and users face much lower psychological costs when holding and spending dollar stablecoins compared to other currencies.
Second, USDC and USDT benefit from a more mature payment infrastructure ecosystem. From wallet support and exchange liquidity to merchant settlement and cross-chain integration, the two major dollar stablecoins have achieved network effects. The most critical competitive dimension in payment scenarios isn’t issuance itself, but the usage network built around payments—merchants are willing to integrate, users are willing to hold, and card networks are willing to collaborate, forming a positive feedback loop.
Third, stablecoins are connecting traditional payment systems through the crypto card model. Users hold USDC or USDT for spending, which are automatically converted at payment, and settlement is completed via Visa or Mastercard merchant networks. Merchants ultimately receive fiat currency. In this process, stablecoins don’t replace traditional payment networks; instead, they function as the clearing layer and settlement channel behind them, leveraging blockchain’s efficiency and stability to optimize fund flows.
Why Euro Stablecoins Fell Behind
EURe’s dramatic drop from 88% to 2% cannot simply be attributed to the failure of euro stablecoins themselves. The EU’s Markets in Crypto-Assets Regulation (MiCA) played a pivotal role. MiCA established a clear compliance framework, giving certain stablecoins regulatory advantages. Circle’s USDC was early to position itself as a MiCA-compliant option, which granted USDC a structural competitive edge in the European market. Ironically, a regulation intended to standardize Europe’s crypto market ultimately accelerated dollar stablecoins’ dominance in the eurozone.
Additionally, the deep integration between Gnosis Pay and EURe meant that the decline of this stablecoin almost directly dragged down Gnosis chain’s share of card settlements. As new projects opted for broader dollar stablecoin solutions and more diversified settlement chains, EURe’s single-ecosystem disadvantage became increasingly apparent.
Payment Entry Points Are the Next Battleground
While monthly transaction volume of $759 million is still minuscule compared to the trillions processed by traditional card networks, the 2.5x annual growth rate indicates the market is moving beyond early adoption and into a commercial expansion phase.
Looking ahead, competition in stablecoin payments will shift from "who issues stablecoins" to "who controls payment entry points." Wallets are the user gateway, payment cards are the spending gateway, blockchains are the settlement infrastructure, and merchant networks are the real-world usage scenarios. Whoever can build a complete, closed-loop ecosystem across these layers will emerge as the next phase winner.
For the crypto market, expanding payment scenarios means greater stablecoin circulation, increased on-chain activity, and a reassessment of infrastructure value. Stablecoin-related projects, wallet providers, payment card issuers, and the RWA (real-world asset) sector are likely to be the main beneficiaries of this trend.
Stablecoins are evolving from settlement tools for crypto trading into payment infrastructure connecting digital assets with the real economy. The $759 million monthly transaction volume for crypto payment cards may be just the first milestone on a long upward trajectory.
FAQ
Q1: How do crypto payment cards convert stablecoins to fiat currency?
When users make purchases with a crypto payment card, their stablecoins (such as USDC or USDT) are automatically converted at the point of sale into local fiat currency. Merchants receive traditional fiat settlements. For both merchants and consumers, the process is indistinguishable from a standard card transaction, and users don’t need to pre-convert crypto assets to fiat.
Q2: Why did EURe’s market share plunge from 88% at the start of 2024 to just 2%?
EURe’s decline was driven by three main factors: first, the global liquidity advantage of dollar stablecoins; second, MiCA regulations gave USDC a compliance head start; third, the tightly coupled ecosystem between Gnosis Pay and EURe lost competitiveness as new projects launched.
Q3: Which blockchains are currently used for crypto payment card settlement?
As of July 2026, Optimism processes about 29% of crypto payment card transaction volume, Solana and Base each handle roughly 19%, and the once-dominant Gnosis chain has fallen to around 2%. Settlement chain diversification is a direct result of new payment projects coming online.
Q4: What is the current size of the crypto payment card market?
In July 2026, monthly transaction volume for crypto payment cards reached $759 million, up about 2.5 times year over year, with nearly 9 million transactions and an average value of $86 per transaction. Compared to the trillions processed monthly by traditional card networks, the market remains in its infancy.
Q5: What does the rise of crypto payment cards mean for the stablecoin market?
Crypto payment cards expand stablecoin usage from trading settlement and DeFi to everyday spending, boosting demand for stablecoin circulation and on-chain activity. This shift from "speculative asset" to "payment tool" may drive a reassessment of the value of payment-related wallets, card projects, and the RWA sector.
