How US stablecoin cards are structured and regulated: sponsor bank, program manager, processor, the GENIUS Act, Visa USDC settlement, FDIC coverage, tax.
A US stablecoin card runs on the same structure as any prepaid or debit card: a sponsor bank issues it, a program manager runs it, and a processor approves each purchase. The GENIUS Act, signed July 18, 2025, adds federal rules for payment stablecoins. Visa now lets some US partners settle card activity in USDC.
That gives builders two separate rulebooks. Banking and card rules apply to the card. Stablecoin and money-transmission rules apply to the balance behind it. Users mostly feel the difference in two places: deposit insurance and taxes.

Key takeaways
For how stablecoin cards work in general, start with what stablecoin card issuing is.
Four parties run a US card program, and a fifth handles the stablecoin. The sponsor bank carries the most regulatory weight because every card runs on its BIN.
Quick definitions:
| Party | Main job | Who oversees it |
|---|---|---|
| Card network (Visa, Mastercard) | Routes transactions, sets program and dispute rules | Its own rules, enforced on members |
| Sponsor bank | Legal issuer, owns the compliance program | Federal or state bank regulator |
| Program manager | Onboarding, limits, support, reporting | The sponsor bank, by contract |
| Processor | Authorizations, card controls, audit logs | The sponsor bank and network |
| Stablecoin provider | Holds or converts the stablecoin | Money transmission and stablecoin rules |
In a self-custodial program, the stablecoin stays in the user's own smart account, so the last row changes. The card side does not. Stablecoin card issuing compliance lists each party's duties in more detail.
The GENIUS Act creates a federal framework for payment stablecoins and the companies that issue them. It does not create a new card license. Card programs keep running under banking and network rules.
President Trump signed the act on July 18, 2025, and it became Public Law 119-27. The White House fact sheet summarizes what the law covers.
For a card program, the practical effect is on which stablecoins the balance can hold. A sponsor bank will ask which stablecoin the program spends from and who issued it, and the federal framework gives both sides a common reference point for that question. The GENIUS Act explained for businesses covers issuer rules, and what the GENIUS Act means for USDT covers foreign-issued stablecoins.
Visa now lets some US issuers settle card activity with Visa in USDC instead of converting to dollars first. The cardholder and the merchant see no difference. The change is in how the issuer pays the network.
On December 16, 2025, Visa launched stablecoin settlement in the United States. Cross River Bank and Lead Bank were the initial banking participants, settling with Visa in USDC over Solana, and Visa said broader US availability was planned through 2026. At the time, Visa reported a $3.5 billion annualized stablecoin settlement run rate as of November 30, 2025.
By April 29, 2026, the settlement pilot supported nine blockchains and had reached a $7 billion annualized run rate, up 50% from the prior quarter. That is settlement volume, not card spend. Do not add it to card volume figures.
The step-by-step path of one purchase, from authorization to merchant payout, is in how stablecoin card transactions settle.
Generally no. The card may be issued by an FDIC-insured bank, but the stablecoin balance behind it is not a bank deposit.
The FDIC's crypto fact sheet says deposit insurance does not apply to crypto assets and does not protect against the default, insolvency, or bankruptcy of non-bank entities, including crypto custodians and exchanges. Read the program terms to see who holds your stablecoins and what happens if that company fails. Are stablecoin cards safe? walks through the risks.
The IRS treats digital assets as property, so spending them can be a reportable disposal. Dollar stablecoins usually produce tiny gains, but each purchase may still need a record.
The IRS digital assets page says digital assets are property, not currency, and lists exchanging them "for property, goods or services in any amount" among the transactions covered. Form 1040, 1040-SR, and 1040-NR each ask a yes or no question about digital assets. Some exchange-linked cards, such as the Coinbase Card, spend from a Coinbase balance and convert at the time of purchase, which is the disposal point. Are stablecoin card purchases taxable? has a record-keeping checklist.
Card rules require identifying every cardholder, and stablecoin transfers add sanctions and Travel Rule duties. Both apply at once.
For users, little changes at the checkout. For builders, the choices are about settlement, custody, and the bank partner.
| Topic | What it means for users | What it means for builders |
|---|---|---|
| GENIUS Act | Clearer rules for the stablecoins behind the card | Pick stablecoins that a sponsor bank will accept |
| Visa USDC settlement | Nothing visible at checkout | Less fiat buffer if your issuer supports it |
| FDIC coverage | Stablecoin balance is not insured | Disclose this clearly in terms and onboarding |
| Taxes | Purchases can be reportable disposals | Give users exportable transaction history |
| Compliance | ID checks before the card is issued | Agree who runs KYC, sanctions, and monitoring |
A card pays merchants. Rent, payroll, and transfers to a user's own bank need ACH, RTP, or wire. A US program that only offers a card leaves those payments unsolved.
BlindPay is the payout and funding layer for that gap. It converts USDC and USDT into dollars and pays out over ACH, RTP, and domestic wire, with RTP settling instantly and ACH in about 1 to 2 business days, per its payment methods reference. The same API pays out over Pix, SPEI, SEPA, and SWIFT (POBO/COBO) with UETR tracking and MT103 confirmations.
On the funding side, US virtual accounts give each customer a routing and account number. ACH, wire, and SWIFT deposits convert to USDC or USDT and land in the linked wallet. A live quote locks the rate and fees before stablecoins move, payouts need no pre-funding, and KYC, KYB, and sanctions screening run in the same API flow.
Lock in the bank partner and the money flows before you design the card. Most delays come from bank review, not engineering.
Map the payments your users make outside the card, then test them. Create a free BlindPay development instance to run ACH and RTP payouts and virtual account deposits with test stablecoins while your card program goes through bank review.
