Why Cards Matter in an Onchain World
Blockchains have solved one of the hardest problems in money movement: trustless, global, programmable settlement. What they have not yet solved at scale is how that money gets spent in the everyday economy.
Today, crypto assets move with finality onchain, while the vast majority of economic activity remains resolutely offchain. Commerce happens at point‑of‑sale terminals, in checkout flows, and across payment gateways that were designed long before stablecoins existed.
Wallet‑to‑wallet stablecoin payments work well when both sides of the transaction are already onchain. But most of the real economy is not.
Stablecoins have crossed $300B1 in circulation. 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?
Stablecoin-linked cards are now processing ~$18B annualized after launching in 2025.2
The answer is a stablecoin-linked card program. And the window 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 buying things because the commerce infrastructure stack was built around cards. Every POS terminal, payment gateway, and checkout flow already supports them. There’s no new behavior required at the point of sale, and no new 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:
- Utility they've been waiting for. Stablecoin holders want to spend without converting back to fiat manually, dealing with exchange delays, or incurring withdrawal fees. A card solves this instantly.
- 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. And it shouldn’t require days of advance planning to prefund multiple accounts and wallets.
- Global spend. Stablecoins are dollar-denominated. Users can spend anywhere Visa/Mastercard is accepted.
- Flexibility until spend. Convert‑at‑spend preserves the always‑on liquidity of stablecoins until payment, delivering a level of flexibility that traditional bank accounts (bound to bank hours) can’t match.
For Your Business
- New, recurring revenue per user. Every swipe generates interchange, additional revenue to what your program is capturing today.
- 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, stickier relationship with your product.
- You become the primary financial relationship. one card, one balance across crypto and fiat spending, every day.
- Reserve efficiency at scale. Programs that access direct stablecoin settlement with the networks can right-size their fiat reserves no longer held up for weekend and holiday settlement gaps.
- Brand reach at every swipe. Every transaction is a branded moment. For crypto companies, the card is a visible signal of real-world utility.
For the Ecosystem
Stablecoin card programs are the on ramp to mainstream crypto adoption because they're genuinely useful, not just because they're leveraging flashy new technology. Every time a user swipes a stablecoin-linked card at a coffee shop, they've proven that onchain money works in the real world.
Why this moment matters
Wallet‑to‑wallet payments will continue to grow, and they should. 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 existing payment rails. That’s where the real tradeoffs begin.
