Crypto card payment volumes hit a cumulative $7.8 billion as of May 28, 2026, according to on-chain analytics firm Paymonscan. Monthly transaction volumes reached $656 million in May, up 142% from $271 million in May 2025. A single provider — Hong Kong-based RedotPay — processes 80.7% of all volume, while Visa handles approximately 90-97% of card-network settlement.
The acceleration is structural, not speculative. Stablecoins now fund roughly 90% of crypto card transactions, with USDT and USDC splitting the bulk of spend. The passage of the GENIUS Act in July 2025, which created the first U.S. federal framework for payment stablecoins, preceded a measurable inflection in adoption curves. Visa and Stripe subsidiary Bridge announced plans to expand stablecoin-linked cards from 18 markets to more than 100 countries by year-end 2026. Mastercard launched a 100-partner Crypto Partner Program in March 2026. The infrastructure layer is converging: legacy card rails now settle on-chain transactions at scale.
This report examines who is spending, where the volume concentrates, which networks carry the load, and what the competitive dynamics mean for value capture in the payments stack.
Cumulative on-chain crypto card payment volumes crossed $7.8 billion as of late May 2026, according to Paymonscan data cited by Benzinga. Monthly volumes have followed a consistent upward trajectory:
| Period | Monthly Volume | YoY Change | |--------|---------------|------------| | May 2025 | $271M | — | | September 2025 | ~$100M* | Baseline (pre-GENIUS Act acceleration) | | March 2026 | $607M | +211% vs. March 2025 | | April 2026 | ~$600M | Sustained | | May 2026 | $656M | +142% vs. May 2025 |
*Note: The September 2025 baseline reflects pre-acceleration figures; volume grew 500% from September 2024 to April 2026 per CoinDesk data.
The cumulative figure crossed $6.5 billion across 21.4 million transactions by March 2026. The run-rate as of May 2026 implies annualized card spend approaching $7.9 billion, though seasonality and market conditions affect extrapolation. CoinDesk reported annualized crypto card spending at $18 billion in January 2026 using a broader methodology that includes off-chain settlement.
RedotPay, a Hong Kong-headquartered issuer operating in more than 100 countries, controls 80.7% of tracked on-chain card volume — $5.1 billion in cumulative spend. The company reports 6 million registered users and annualized payment volume exceeding $10 billion.
RedotPay's dominance represents a slight decline from approximately 88% at the start of 2025, indicating competitors are gaining share at the margin. Still, the gap is enormous: RedotPay processes more than 12 times the volume of its nearest rival.
The remaining 19.3% is split among at least 11 tracked platforms. Gnosis Pay, the only card natively linked to a non-custodial Safe wallet, holds 2.6% share with $167 million in volume. Its zero foreign-exchange fee model and up to 5% GNO cashback target European users specifically.
RedotPay's user base skews heavily toward emerging markets. Bangladesh, India, Egypt, and Nigeria represent the largest user concentrations. The United States contributes a small fraction of overall traffic — a geographic distribution that reflects where crypto cards solve the most acute financial infrastructure gaps.
USDT and USDC account for approximately 90% of crypto card funding. The split varies by geography:
The stablecoin market underpinning this spend reached $323 billion in total market capitalization in May 2026. USDT holds $190 billion (58.3% share); USDC holds $77.6 billion. Together, Tether and Circle control more than 80% of stablecoin supply.
Blockchain network distribution for card settlements tells its own story. According to The Block, TRON captured 35% of March 2026 payment volume by blockchain, with BNB Chain at 15%. This distribution reflects fee economics — TRON's sub-cent transaction costs make it the rational choice for high-volume, low-value card settlements — rather than ideological network preference.
Visa processes between 90% and 97% of crypto card volume (the range reflects different measurement periods in 2026). In March 2026, Visa settled $581.8 million of the $607 million monthly total. The company's partnership with Stripe subsidiary Bridge, announced in March 2026, aims to bring stablecoin-linked card issuance to more than 100 countries by year-end, up from 18 markets currently live. The cards allow spending directly from self-custody wallets including MetaMask and Phantom, with transactions processed across Visa's 175 million merchant locations.
Bridge's settlement architecture routes transactions on-chain via Lead Bank, a notable shift from earlier models that converted stablecoins to fiat at the point of sale.
Mastercard launched its Crypto Partner Program on March 10, 2026, enrolling more than 100 companies including Binance, Circle, Coinbase, PayPal, Ripple, JPMorgan Chase, and Stripe. The program connects participants to Mastercard Move Cross-Border Services, which reaches more than 95% of the world's population. OKX launched a Mastercard-powered stablecoin card in Europe in January 2026, processing transactions at more than 150 million merchant locations with a 0.4% market spread and no additional fees.
The competitive dynamic is clear: both networks are building dedicated crypto infrastructure rather than treating digital asset cards as a niche product line. The difference is scale — Visa's head start in partnership volume gives it a structural advantage in settlement data and issuer relationships.
Two regulatory frameworks have materially accelerated crypto card adoption:
GENIUS Act (U.S.): Signed into law on July 18, 2025, the Guiding and Establishing National Innovation for US Stablecoins Act passed the Senate 68-30 and the House 308-122 with bipartisan support. The law requires 1:1 reserve backing with cash or short-term Treasurys, monthly reserve disclosure, legal protections for holders in issuer insolvency, and — critically — excludes compliant payment stablecoins from SEC and CFTC jurisdiction. Stablecoin adjusted volume reached approximately $4.5 trillion in Q1 2026, with growth accelerating after the Act's passage.
MiCA (EU): The Markets in Crypto-Assets regulation provided a compliance path for card issuers operating in Europe. OKX obtained a Payments Institution license in Malta ahead of the March 2026 enforcement date, enabling its European card operations under both MiCA and PSD2 frameworks.
These frameworks removed the primary regulatory uncertainty that had constrained institutional participation in stablecoin payment infrastructure.
Crypto card adoption concentrates in two distinct market types:
Emerging markets (majority of volume): Users in Bangladesh, India, Egypt, Nigeria, Argentina, Colombia, and other developing economies use crypto cards primarily for:
The Visa-Bridge expansion into Latin America — starting with Argentina, Colombia, Ecuador, Mexico, Peru, and Chile — targets precisely this demand. Dollar-denominated stablecoins have demonstrated organic adoption in countries with currency instability.
European markets (growing share): OKX Card data from Europe shows food-related spending at 44% of transactions, with grocery stores and supermarkets at 26%. This suggests crypto cards in developed markets are transitioning from novelty to utility — users spend on daily necessities, not just discretionary purchases.
The crypto card market in 2026 features distinct competitive tiers:
| Tier | Players | Strategy | |------|---------|----------| | Dominant | RedotPay (80.7%) | Emerging-market scale, Visa-linked, USDT-centric | | Infrastructure | Visa + Bridge, Mastercard CPP | Network-level settlement, 100+ country expansion | | Exchange-linked | OKX, Bybit, Crypto.com, Binance | Cross-sell from trading to spending | | DeFi-native | Gnosis Pay (2.6%), KAST, Pengu Card | Non-custodial wallet integration, on-chain settlement |
The exchange-linked tier is notable for its distribution advantage. OKX, Bybit, and Binance can convert existing trading users to card users at near-zero acquisition cost. However, their card products compete on rewards and fees rather than structural differentiation.
DeFi-native cards represent the smallest volume share but the most architecturally distinct model. Gnosis Pay's direct integration with Safe wallets eliminates custodial intermediaries. Pengu Card, built on Solana, enables USDC and USDT spending at an estimated 150 million merchants globally.
Baanx, a previously independent card infrastructure provider, was acquired by a U.S.-based crypto wallet company for approximately $175 million in November 2025 — signaling consolidation in the middleware layer.
The economics of crypto card payments distribute value across a layered stack:
The critical observation: traditional card networks capture the largest share of per-transaction value, while crypto-native infrastructure handles settlement. This is integration, not disruption — stablecoins slot into existing payment rails rather than replacing them.
The $7.8 billion crypto card market represents a functional proof point for stablecoin utility beyond trading and DeFi. Growth is concentrated where the use case is most acute — emerging markets with weak local currencies and limited banking access — rather than in developed economies where existing payment infrastructure works adequately.
The market structure is lopsided. RedotPay's 80.7% share indicates the sector remains early-stage, dominated by a single issuer with first-mover advantage in underserved geographies. Whether that concentration persists depends on execution by Visa-Bridge (100+ country expansion), exchange-linked cards (OKX, Bybit, Binance converting trading users), and DeFi-native issuers (Gnosis Pay, Pengu Card) offering non-custodial alternatives.
The value-capture question matters most. At present, Visa and Mastercard extract the largest per-transaction fee share by providing the merchant acceptance network that makes crypto cards usable. Stablecoin issuers benefit from increased float. Blockchain networks collect gas fees on settlement. Card issuers retain thin spreads. This is an additive model — stablecoins extending the existing payments stack — rather than a replacement model. The economic structure mirrors traditional payment flows with a different settlement layer, which is precisely why adoption has accelerated: merchants see Visa, consumers see their wallet balance, and the stablecoin settlement happens invisibly between them.
