What actually happened in March

The $607 million figure comes from PaymentScan, which tracks on-chain crypto card transactions across protocols whose data is publicly verifiable. The important caveat: this number only includes on-chain trackable cards from crypto-native issuers. It does not include cards from centralized exchanges like Binance, Bybit, or Coinbase — whose transaction data isn't publicly identifiable on-chain.

The real number is estimated to be well above $1.5 billion per month when exchange cards are included. The $607 million is the floor, not the ceiling.

Among the trackable issuers, RedotPay dominated with approximately $391 million in volume — more than half the total market. EtherFi Cash and KAST each processed around $60 million. By transaction count, EtherFi led with over 800,000 transactions, suggesting smaller average ticket sizes and more frequent, everyday spending.

Visa processed 97% of the total volume — $581.8 million. Mastercard accounted for just 3%. This isn't a commentary on Mastercard's strategy as much as it's a reflection of Visa's early and aggressive move into crypto card infrastructure, including stablecoin settlement pilots and principal member partnerships with crypto-native issuers.

The stablecoin engine underneath

The real story isn't the cards. It's what's loaded on them.

USDT accounted for 62% of total crypto card volume in March. USDC captured 27%. Together, stablecoins powered nearly 90% of all crypto card spending. The remaining volume came from native tokens like ETH and BTC, mostly through programs that let users spend without selling their holdings by using crypto as collateral for a credit line.

This is the critical insight: crypto cards are not really "crypto" cards. They're stablecoin cards. Users aren't spending Bitcoin at the grocery store. They're spending dollar-denominated stablecoins through a Visa card at a merchant that sees a perfectly normal card transaction. The crypto part is invisible. The experience is identical to a regular debit card. The settlement layer is entirely on-chain.

TRON captured 35% of March's blockchain-level transaction volume, followed by BNB Chain at 15%. This distribution reflects fee economics — TRON's near-zero transaction costs make it the cheapest rail for stablecoin settlement, which is why issuers and users gravitate toward it for high-frequency card spending.

Southeast Asia accounted for approximately 60% of global stablecoin payment volume during this period. Local card issuance in the region grew 83x between 2024 and 2025. These aren't early adopters anymore. These are populations using stablecoins as their primary interface with the global financial system — and doing it through cards that work at 100 million merchants worldwide.

What the growth curve looks like

To understand why March's number matters, you need to see the trajectory:

Early 2023: roughly $100 million per month. Late 2024: still around $100 million per month. Early 2025: $187 million in March. Late 2025: $1.5 billion per month at peak. January 2026: $550 million. February 2026: $523 million. March 2026: $607 million — all-time high.

The compound annual growth rate from early 2023 to late 2025 was 106%. On an annualized basis, the market hit an $18 billion run rate by the end of 2025 — nearly matching peer-to-peer stablecoin transfers, which were at $19 billion and growing at just 5% over the same period.

Cards are winning the spending race because they require zero merchant integration. A stablecoin settles on-chain, converts to fiat at the point of sale, and arrives at the merchant as a standard Visa or Mastercard payment. The merchant doesn't know. The merchant doesn't need to know. The existing payment acceptance infrastructure — 100 million locations, every country, every currency — is already built.

This is why direct stablecoin merchant payments, despite all the hype, still haven't overtaken cards. Cards run on rails that already exist. Stablecoin merchant acceptance requires new integrations, new checkout flows, and new settlement processes. Cards just work.

Three signals for anyone building payment products

Signal 1: The spending use case has decoupled from the trading use case.

JPMorgan reported that total crypto inflows fell to $11 billion in Q1 2026 — one-third of the prior year's figure. Yet the same quarter produced a record $607 million in monthly card spending. Institutional flows contracted. Retail spending expanded. These two tracks are now moving in opposite directions simultaneously.

This matters because it means crypto card adoption is no longer correlated to market euphoria. People aren't spending because crypto is booming. They're spending because the cards are genuinely useful — cheaper cross-border transactions, instant settlement, better rewards, and access to financial services that their traditional bank doesn't offer. The utility has become self-sustaining.

For anyone building payment products, this decoupling is the clearest possible signal: stablecoin-powered spending is not a bull market phenomenon. It's infrastructure.

Signal 2: Regulatory clarity is accelerating, not restricting, growth.

The GENIUS Act, signed into law in July 2025, gave stablecoins a federal legal framework in the United States. The SEC and CFTC issued landmark guidance in March 2026 classifying Bitcoin and Ethereum as non-securities. Mastercard acquired BVNK for $1.8 billion. Charles Schwab announced plans to offer spot crypto trading.

Every one of these moves reduced the compliance cost for card issuers and removed a barrier to scaling. The March volume record didn't arrive in a vacuum — it arrived on the other side of regulatory clarity that the industry had been waiting for since 2020.

For builders, the implication is simple: the regulatory window is open. The compliance cost of launching a crypto card product has never been lower. The legal risk has never been more manageable. The time to build is now, not after the next regulatory cycle.

Signal 3: The next wave of card users is already queuing up.

Charles Schwab's announcement that it will offer spot crypto trading opens the door to a retail investor base that has historically been excluded from crypto card products. These are people who will hold crypto through a trusted brokerage and eventually spend it through card infrastructure that already exists.

Meanwhile, 39% of U.S. merchants already accept crypto, and 88% report customer inquiries about paying with digital assets. The demand side is growing from both directions — more users holding crypto, and more merchants expecting to accept it.

The issuers and platforms that have card programs live today are the ones that will capture this incoming wave. Those still in development will be competing for second position in a market where the leader already has $391 million in monthly volume.

What this means for the next 12 months

The March record is almost certainly not the peak. Here's why.

The $607 million only counts on-chain trackable cards. Exchange cards likely add another $900 million or more. Total real-world crypto card spending is probably already above $1.5 billion per month.

Stablecoins are growing their share of card transactions — from negligible in 2023 to nearly 20% of all transactions by early 2026. If stablecoin share reaches 30% by year-end, and new retail entry points like Schwab add another cohort of card-eligible holders, monthly volume could approach $2 billion before 2027.

Visa's stablecoin-linked card spend hit a $3.5 billion annualized run rate in Q4 2025. That run rate is almost certainly higher now. Visa is not building stablecoin settlement infrastructure as an experiment. They're building it because the transaction revenue is real, the growth is compounding, and the merchants are already connected.

For anyone in the payment product space — fintechs, neobanks, platforms, or brands considering embedded finance — the signal is unambiguous. Crypto cards are no longer alternative payments. They're the fastest-growing segment in consumer card spending, growing 106% annually while traditional card spending grows in single digits.

The opportunity for new entrants

Here's the part that most coverage of the March record misses: the market is still early and fragmented.

RedotPay controls more than half of trackable volume. EtherFi and KAST each have about 10%. That leaves roughly 15-20% split among dozens of smaller issuers. There is no clear second-place player at scale.

The product differentiation between existing crypto cards is minimal. Most offer the same basic feature: load stablecoins, spend via Visa. The cards that will win the next phase of this market will differentiate on the wrapper — the brand, the user experience, the rewards structure, the DeFi integration, and the geographic focus.

This is where white-label card programs become decisive. A brand, platform, or fintech with a loyal user base doesn't need to build card infrastructure from scratch. They need a partner who handles Visa integration, stablecoin settlement, compliance, and card production — while the brand owns the customer relationship and the product experience.

This is exactly how the fastest-growing card programs in the Omni ecosystem are built. The card infrastructure is shared. The brands, markets, and user experiences are completely different. One platform builds everyday banking. Another builds cards for AI agents. A third serves privacy-focused clients. Same rails, different products, each capturing a slice of a market that just crossed $607 million in a single month.

The bottom line

$607 million in one month. $6.6 billion cumulative. 22 million transactions. 211% year-over-year growth. 106% compound annual growth rate. 97% on Visa. 90% powered by stablecoins.

These are not niche numbers from a fringe industry. These are the vital signs of a new payment rail being built inside the existing global acceptance infrastructure — using cards that merchants already accept, networks that consumers already trust, and stablecoins that settle in seconds for fractions of a cent.

The question isn't whether crypto cards are the future of spending. The data has already answered that. The question is who builds the next generation of card products on top of this rail — and how fast they get to market.

The infrastructure is ready. The regulatory framework is in place. The demand is proven. The market rewards speed.
