Key takeaways
- To the merchant, a stablecoin-funded card sale is a normal Visa or Mastercard sale. You get paid in dollars, normal chargeback rules apply, and no crypto lands on your books.
- What you pay depends on how the issuer registers the card (debit, prepaid or commercial) and which country issued it. The stablecoin behind it doesn't set the price.
- Don't put up "crypto accepted" signs because you take these cards, and don't block them on a hunch. Check whether your existing prepaid-card rules would catch them.
- Ask your processor now for a report of sales by card type and issuing country, so you have a baseline before these cards arrive in volume.
Stablecoin funded cards look like any other Visa or Mastercard at your terminal, and for merchants that's the point. Euronet announced a partnership expansion on Oct. 19, 2026. Under it, banks and fintechs that issue cards on Euronet's Ren and CoreCard platforms can use Fireblocks' embedded wallets to launch cards that spend a stablecoin balance. You accept the card the way you accept any card, and you get paid in dollars through your usual processor. No wallet, no tokens, no crypto on your books.
What can change is harder to see: which interchange category the card falls into, whether it was issued abroad, and how your processor reports it. Those are the questions worth asking now, before these cards show up in your batches.
What the Euronet-Fireblocks Stablecoin Deal Covers
Payments Dive reported the deal on Oct. 26, citing Euronet's Oct. 19 release. According to the Euronet press release, banks, fintechs and other financial institutions can launch their own stablecoin-funded card programs on Ren and CoreCard. Fireblocks supplies the wallet infrastructure that holds and moves the stablecoin balances. Euronet will sell it as a white-label product, so a bank can put the card inside its own banking or wallet app while the two companies run the infrastructure behind it. Coverage of Euronet's third-quarter earnings call adds that the program was introduced at Money20/20 and that the cards are meant to be accepted wherever Visa and Mastercard are accepted.
The two companies already work together. Euronet began using Fireblocks in October 2025 for partner settlement and pre-funding in its cross-border payments business. Fireblocks says it facilitates more than $300 billion in stablecoin volume a month on average. Euronet's release also cites Visa data: more than 160 stablecoin-linked card programs were live on the Visa network in Visa's fiscal second quarter of 2026, with payment volume on those programs up nearly 200% year over year.
The release describes something issuers can now build. It doesn't tell merchants which banks will issue these cards, in which countries, or when. Treat it as a trend to prepare for, not a change to make this week.
How a Stablecoin-Funded Card Works, From Wallet to Card Network
According to the release as published on Finextra, each cardholder gets an embedded wallet when they sign up. Money they deposit in regular currency is converted to stablecoin before it's credited. Cardholders log in with credentials they already use. There's no seed phrase and no separate crypto app.
When that cardholder taps, dips or types the card number at your checkout, the sale moves like this:
- Your terminal or gateway sends a normal authorization request through your processor to Visa or Mastercard.
- The network routes it to the card issuer, which runs its program on Ren or CoreCard.
- The issuer checks the cardholder's stablecoin balance in the Fireblocks wallet and approves or declines.
- The sale clears and settles through the network like any card sale, and your processor deposits dollars on your normal schedule.
Step 3 is the only part that touches crypto, and it happens on the issuer's side of the network. In Euronet's words, merchants "continue to receive local currency." If you want a refresher on who decides what in that chain, our explainer on how card networks and issuing banks split control of a transaction walks through it.
What Changes at Your Checkout and What Stays the Same
Almost everything stays the same. Your terminal, gateway, merchant category code, batch timing, deposit schedule and refund process don't change, and there's nothing to install. If your countertop terminal or retail payment setup takes Visa and Mastercard, it takes these cards. The same goes for an online payment gateway at an e-commerce checkout.
Three things deserve attention.
The card product type. The issuer decides how to set up the card with the network: as debit, as prepaid or, possibly, as a commercial card, since the release mentions businesses as well as consumers. That setup decides which rate category applies. The stablecoin behind the card doesn't.
The issuing country. The partners say they want to take stablecoin card programs into new markets. A card issued outside the U.S. is a foreign card at your terminal, no matter what funds it.
Your signage and staff script. Accepting stablecoin cards isn't the same as accepting crypto. Your customer paid with a Visa or Mastercard, and you received dollars. Don't add "crypto accepted" to your door or website just because you take these cards. Give staff the simple version: if it's a Visa or Mastercard, it works like one.
Refunds go back to the same card as a standard card refund. How the issuer credits the cardholder's wallet afterward is between the issuer and the cardholder.
Interchange, Settlement Currency and Chargebacks on Stablecoin Cards
Interchange. The networks set interchange by card product, how the card was accepted (tapped in store or keyed online), your merchant category and where the card was issued. Nothing in the announcement points to a separate "stablecoin" interchange category. Expect these cards to cost what the product the issuer registered them as costs. A business version could land in a commercial category, and commercial rates in the network tables generally run higher than consumer debit.
The mistake to avoid is blaming the stablecoin for a cost that comes from somewhere else. Here's an illustrative example for a hotel or tour operator. Assume a $400 booking on interchange-plus pricing. Assume the all-in cost is 2.2% for a domestic consumer card and 3.0% for a card issued abroad once cross-border fees are added. These rates are made up for the arithmetic, and your statement will differ.
| Illustrative scenario | Assumed all-in rate | Cost on a $400 sale |
|---|---|---|
| Domestic consumer card, stablecoin-funded | 2.2% | $8.80 |
| Domestic consumer card, bank-account-funded | 2.2% | $8.80 |
| Foreign-issued card, stablecoin-funded | 3.0% | $12.00 |
The $3.20 gap comes from the country that issued the card, not from what funds it. Our guide to cross-border fees vs. foreign transaction fees explains who pays which charge. Travel businesses take more foreign-issued cards than most, so they're the merchants most likely to notice.
Settlement currency. A U.S. merchant receives U.S. dollars, as with any card sale, so the stablecoin's price can't move your deposit. If you sell abroad and settle in other currencies through an international payments setup, that arrangement doesn't change either.
Chargebacks. These are Visa and Mastercard card transactions, and the release doesn't describe any separate dispute process. Plan on the networks' normal dispute rules applying. A cardholder who funded the card with stablecoins can still file a chargeback for fraud, an order that never arrived or a product that wasn't as described. The usual time limits for filing a chargeback apply. Keep the same evidence you keep for every sale.
Fraud and Cardholder-Verification Questions for Your Processor
Wallet security is the issuer's job. Login, account recovery and the stablecoin balance all sit with the bank or fintech and with Fireblocks. Your job is the same as for any card. In store, that means taking chip or contactless payments. Online, it means CVV and address checks, plus 3-D Secure authentication where the issuer supports it.
Because these programs are new, a few questions are worth sending to your processor now:
- How will these cards appear in my reporting: as debit, prepaid or commercial? Will the issuing country show?
- I have rules on prepaid cards for subscriptions or high-ticket orders. Would those rules catch these cards, and should they?
- Do the issuers on these programs support 3-D Secure and address verification for card-not-present sales?
- Will my statement break out interchange by card type so I can see what these sales actually cost?
Don't block these cards on a hunch. A blanket rule against crypto-linked cards would turn away paying customers whose cards work like any other. To them, it would show up as a false decline even though they did nothing wrong.
Stablecoin Cards vs. Direct Stablecoin Acceptance: Which Matters More
People often lump cards funded by stablecoins together with accepting stablecoins directly, but they're different decisions.
| Stablecoin-funded card | Direct stablecoin acceptance | |
|---|---|---|
| What you receive | Dollars from your processor | Stablecoins, or dollars from a conversion provider |
| Setup needed | None beyond normal card acceptance | Wallet or provider, accounting and tax treatment |
| Disputes | Card network chargeback rules | No card network dispute system; refunds are transfers you send |
| Who handles the crypto | The issuer and its wallet provider | You or your provider |
For most merchants, the card version matters more in the near term because it reaches your checkout through the card acceptance you already have. Direct acceptance is a separate project with its own legal questions and partner choices. If you're weighing it, start with our explainer on what the GENIUS Act means for merchants and our guide to vetting a crypto payment partner.

The law on stablecoins is still changing, so check the details with a qualified professional before you change how you take payment.
Ask for a Card-Type Report Before These Cards Arrive
The most useful thing you can do this week is ask your processor for a report of last month's sales by card type and issuing country. With that baseline, you'll be able to see when crypto-linked cards start showing up at checkout and whether they're changing your costs. The open question to watch is which issuers launch on Ren and CoreCard first, and in which markets. How those issuers register the cards with Visa and Mastercard will decide what these sales cost you.
