Grocery spending rises 482% between May and July, but the emerging model relies on converting digital assets into fiat through existing card networks
Stablecoin-funded payments are moving beyond trading platforms and into everyday spending across Europe, as consumers increasingly use digital assets to pay for groceries, transport and fuel through conventional card networks.
OKX said on August 19 that purchase volume through its European card increased 280% year on year this summer, while the number of transactions rose 178%. The figures suggest that digital assets are beginning to function as a source of payment funding rather than solely as investments.
The change was particularly visible between May and July. The number of customers using the OKX Card for groceries increased 221%, while users paying for transport and fuel rose 263%, according to company data.
Spending grew even faster than user numbers. Grocery purchase volume increased 482% during the period, while transport and fuel spending climbed 530%. OKX did not disclose the absolute transaction value or number of cardholders behind those percentage increases, making the scale of the underlying customer base difficult to assess.
Everyday spending patterns diverge across Europe
The data also show marked differences among major European markets. Groceries, transport and utilities accounted for 31.7% of OKX Card spending in Poland, compared with 22.2% in the Netherlands, 20.4% in Germany and 14.1% in France.
Groceries were the most consistent everyday category across the four countries, representing between 9.5% and 19.3% of total spending. Earlier OKX data covering late January to late February found that food-related purchases, including supermarkets and restaurants, accounted for 44% of card transactions in the European Economic Area.
“The most interesting part of this growth isn’t simply that customers are spending more with their OKX Card. It’s what they’re spending on,” said Erald Ghoos, CEO of OKX Europe. “Groceries, transport and fuel are part of everyday life.”
The OKX Card allows eligible European customers to fund purchases with supported stablecoins held in an OKX Pay account. At the point of purchase, the assets are converted into euros and the merchant receives conventional fiat currency through the Mastercard network. The virtual card can also be used through Apple Pay and Google Pay where available.
This distinction is important. The increase does not necessarily mean that European retailers are directly accepting cryptocurrencies. Instead, it shows how digital assets can be connected to established payment infrastructure without requiring merchants or consumers to adopt an entirely new checkout system.
Stablecoins enter the existing payment system
The emerging model positions stablecoins as a funding layer behind familiar card transactions. For consumers, the payment experience remains similar to using a conventional debit card. For merchants, settlement continues through the existing fiat-based card network.
That structure could lower one of the main barriers to everyday digital-asset use: the need to persuade retailers to accept and manage cryptocurrencies directly. It also suggests that the next stage of adoption may be determined less by the number of crypto-native merchants than by how effectively digital-asset platforms connect with established payment rails.
However, the sharp percentage increases should be interpreted cautiously. OKX has not disclosed absolute purchase volumes, active-user totals or the extent to which cashback and other promotional incentives contributed to the growth. Longer-term data will be needed to determine whether the pattern represents sustained payment behaviour or an early-stage expansion from a relatively small base.
The broader signal is nevertheless significant. Digital assets are beginning to move into the background of the payment experience: consumers may fund a purchase with stablecoins, while merchants continue to receive euros through infrastructure they already use. That shift—from a separate payment system to an underlying source of funds—may prove more consequential than direct cryptocurrency acceptance itself.
