Why Cards Matter in an Onchain World
Blockchains can move billions in seconds. Stablecoins have crossed $300B in circulation. But most of it still can't be spent at checkout.
While crypto solves how money moves, cards solve how it gets spent.
Crypto-native users want to spend their onchain assets in the real world. Fintechs and brands are either sitting on growing stablecoin user balances or watching the trend and asking: How do we get ahead of this?
Some businesses advocate for wallet‑to‑wallet stablecoin payments as the solution. Wallet‑to‑wallet stablecoin payments are direct transfers between onchain addresses and work seamlessly inside crypto‑native ecosystems. But most of the economy remains offchain, where everyday commerce still runs on point‑of‑sale terminals, payment gateways, and legacy card networks.
The stronger solution is stablecoin-linked card programs. These cards connect stablecoin balances to existing card networks, converting to fiat at the point of purchase, so they work where cards are already accepted, allowing users to hold funds onchain and spend without pre-funding or off-ramping. Stablecoin-linked cards are now processing ~$18B annualized, showing clear early traction.1 The category is still wide open, and the moment to be a first mover is now.
The spending layer is the opportunity
Wallet-to-wallet payments are great for sending money. Stablecoin-linked cards are better for purchases as the commerce infrastructure stack was built around cards. They’re supported by every POS terminal, payment gateway, and checkout flow. No new behavior required at the point of sale, and no additional merchant integration to manage. The blockchain fades into the background, serving as infrastructure, not a user interface.
A stablecoin-linked card program is how you put stablecoins into your users' hands in a way they can use every day, whether you're deepening an existing crypto product or building the entry point into a new one.
Key benefits
For your users:
1. Utility they've been waiting for. Stablecoin holders want to spend without thinking about conversion. This means no manual steps, exchange delays, or withdrawal fees. A card abstracts this entirely, so money moves from balance to purchase, just like any other card payment.
2. No need to split funds between crypto and fiat. Whether they pay with fiat or stablecoins shouldn’t depend on who’s on the other side of the transaction or require days of advance planning to prefund multiple accounts and wallets.
3. Global spend. Stablecoins are dollar-pegged. Users can spend most places where Visa/Mastercard is accepted.
4. Flexibility until spend. Funds stay in stablecoins until the moment of purchase, converting only when needed. This eliminates the need to move money in advance to accommodate traditional bank hours and allows for potential savings by reducing unnecessary conversions, delays, and fees.
For your business:
1. New, recurring revenue per user. Every transaction generates a share of the merchant fee from the card network, incremental revenue on top of what your program captures today.
2. The card becomes a retention mechanism. A card in someone's wallet, physical or digital, is the highest-engagement touchpoint in consumer finance. Daily spend habits compound into a deeper, more durable relationship with your product.
3. You become the primary financial relationship. One card that supports both crypto and fiat spending, without requiring users to manage multiple accounts, while enabling faster settlement and lower fees for merchants.
4. Reserve efficiency at scale. Programs that access direct stablecoin settlement with the networks can optimize liquidity because fiat reserves are no longer needed for weekend and holiday settlement gaps.
5. Brand reach at every swipe. Every transaction is a branded moment. For crypto companies, the card signals real-world utility combined with brand recognition.
For the ecosystem:
Stablecoin card programs are the on ramp to mainstream crypto adoption because they're genuinely useful, not just leveraging flashy new technology. Every time a user swipes a stablecoin-linked card at a coffee shop, it shows that onchain money works in the real world.
Why this moment matters
Wallet-to-wallet payments will continue to grow given their speed and efficiency2. But for real-world spend at scale, cards remain essential.
Deciding to use cards solves for distribution. What comes next is architecture: when and how stablecoins convert, settle, and reconcile inside traditional payment rails.
