Crypto card spending reached $759 million in July, according to on-chain tracker Paymentscan. That is real money. It paid for groceries, ride-hailing, restaurant tabs and streaming subscriptions, settled in stablecoins at the register. It is also not the number that traveled. Several outlets rounded the month up to a billion dollars, and in the rounding they skipped the part worth reading.
The tracked figure is $759 million, not a billion
The $759 million comes from Paymentscan data cited by a16z, and it is up roughly 2.5 times from $306 million in July 2025. Purchases went from about 5.2 million to nearly 9 million over the year. The average card swipe now runs near $86, up from roughly $59. On August 23, CoinDesk headlined the same data set at "$1 billion," a $1.04 billion tally across more than 10 million transactions, and described the growth as more than tripling. The likely reason for the gap is a broader program count in the larger tally. Both reads agree on the shape: crypto card spending has jumped, and dollar stablecoins now fund about 70 percent of it.
USDC now outspends USDT more than two to one
Here is where the loud narrative and the quiet data part ways. Tether's USDT is still the largest stablecoin by a wide margin, worth $183.4 billion in early August against USDC's $71.9 billion, a supply lead of roughly 2.5 times. At the checkout the order flips.
| Metric | USDC | USDT |
|---|---|---|
| Share of card volume, July 2026 | 58% | 26% |
| Share a year earlier | ~48% | ~7% |
| Market cap, early August | $71.9B | $183.4B |
A year ago USDT carried about 7 percent of card volume. Now it holds 26, while USDC climbed to 58. CoinDesk's write-up put the splits lower, closer to 51 and 20 percent, but the direction is the same in every source: the coin that rules supply is losing the point of sale to the one it dwarfs. Even as stablecoin supply contracted for a third straight month, the money changed hands more often.
RedotPay alone did more than half
Strip the headline word "mainstream" and crypto card spending is not spread across a market. It sits in a handful of apps. RedotPay processed $395.1 million in July, up from $266.4 million a year earlier, which is over half of everything tracked. EtherFi added $100.3 million and KAST $89.6 million. Those three programs together ran 77 percent of the $759 million. By chain, Optimism carried about 29 percent of the flow, with Solana and Base near 19 percent each. This is not a hedge against fragility; card rails can break, and one stablecoin program locked users out for an hour in June.
The spending also lands where dollars are scarce. CoinDesk reported that groceries made up 35 percent of card activity in Brazil and 41 percent in Argentina, the same corridor where stablecoin remittances undercut the banks on cost. Gross transaction value in lower-GDP markets rose about 600 percent between March 2025 and February 2026.
For scale, Visa reported $5.2 billion in stablecoin-linked card volume across 2025, up 319 percent, spanning more than 130 programs in over 50 countries. The on-chain slice Paymentscan can see is a fraction of that, so $759 million reads as a floor rather than a ceiling. The number to watch next is whether the concentration loosens as those other programs report, or whether one app keeps writing most of the story.
