Stablecoin-Backed Card Programs [What It Changes]

TL;DR

• Stablecoin-backed card programs let a person or business spend a digital-dollar balance on a normal debit or expense card while the merchant still receives ordinary local currency.

• As of July 22, 2026, Marqeta and zerohash said they will integrate that spend path into existing Marqeta card programs rather than ask merchants to take crypto.

• The constraint that broke is spendability: zerohash cited $7.2 trillion of monthly stablecoin volume in February 2026 against $6.8 trillion on U.S. ACH, while shops still cannot tap those balances at a parts counter.

• Small operators should treat this as a funding-source swap on cards they already issue or already accept, not as a new checkout stack.

Key Takeaways

• The merchant does not change terminals, acquirers, or settlement currency; conversion happens before the card network settles.

• Marqeta keeps issuing, acceptance, and bank relationships; zerohash keeps custody, compliance, and on-chain liquidity, according to the July 22, 2026 release.

• U.S. rails still dominate everyday spend: the Federal Reserve Payments Study counted 187.7 billion card payments in 2024, which is why a card front-end matters more than a QR code at a two-truck shop.

• Balances on these programs are not bank deposits; zerohash discloses that its accounts are not subject to FDIC or SIPC protection.

• Expense, payroll, and receipt workflows already in place can ingest the card authorization as one more event; the finance-accounting agent path is a match, not a rebuild.

What stablecoin-backed card programs actually are

Stablecoin-backed card programs are card products that debit a digital-dollar token such as USDC at the moment of sale and still pay the merchant in ordinary dollars, euros, or other local fiat through the same card networks that already sit on the counter.

That sentence is the whole product. A two-truck HVAC shop that gets paid by a property manager in digital dollars should not have to open a second checking account, wait a two-day ACH, and then reload a Visa just to buy a condenser at the supply house. A ten-person marketing agency that invoices a foreign client in USDC should be able to put media spend, SaaS, and a client dinner on the same expense card the bookkeeper already reconciles. A solo clinic that holds a dollar token overnight should be able to tap it at the pharmacy wholesaler on Monday morning without teaching the cashier a new app.

The reason this is an operations story, not a crypto story, is that cards already dominate U.S. noncash payments by number. The Federal Reserve’s 2025 Payments Study, covering calendar 2024, put cards at 79 percent of noncash payments by count and only 8 percent by value. Small shops live on that count side: small-ticket taps, not million-dollar wires. If digital-dollar balances cannot ride those taps, they stay trapped in wallets while the parts counter still wants a plastic or phone wallet PAN.

Marqeta’s expense-management stack already sells real-time controls, virtual cards, and just-in-time funding to platforms that serve those shops. The July 2026 partnership is an attempt to point those same controls at a stablecoin balance instead of a prefunded fiat bin. For a shop that already codes receipts into a form-to-CRM flow, the change is the funding source, not the receipt.

What shipped on July 22, 2026

zerohash and Marqeta, Inc. (NASDAQ: MQ) announced on July 22, 2026, from Chicago, that they will collaborate to integrate zerohash’s stablecoin infrastructure into Marqeta’s card issuing. The release says the partnership will let Marqeta customers embed stablecoin payments into new and existing financial products without rebuilding core systems or taking on new regulatory burden.

FinTech Global reported the same deal on July 27, 2026, describing cardholders spending stablecoin balances at merchants worldwide while merchants continue to receive fiat through existing networks. That write-up matches the primary release on roles: zerohash on custody, compliance, liquidity, and on-chain settlement; Marqeta on issuing, banking relationships, and network connectivity.

The companies did not say the product was live on July 22. The language is “will collaborate,” “will enable,” and “will let users spend.” Forward-looking statements in the same release point readers to Marqeta’s Form 10-K risk factors via the investor site. Treat the announcement as a committed build on a live issuing platform, not as a claim that every Marqeta bin can debit USDC today.

Marqeta already processed crypto-linked debit in the U.S. and Europe, the July 22 release says, converting crypto holdings into fiat spend and paying crypto rewards. The partnership extends that pattern from crypto-native apps to non-crypto companies that want digital-dollar spendability. Marqeta processed nearly $400 billion in 2025. That figure sits on both the press release and Marqeta’s homepage, which also lists 99.99 percent platform uptime in 2025 and certification in 40-plus countries.

How the spend actually moves

Mastercard’s explainer on crypto cards, dated April 13, 2026, is the clearest public description of the conversion step. A crypto or stablecoin card looks like a normal debit or credit card. At the terminal, the issuer identifies the amount, sells or burns the matching digital-asset amount from the connected wallet, and sends fiat across the card network. The merchant prices in local currency and is paid in local currency. The cashier does not see a chain, a token, or a wallet address.

Mastercard’s Crypto Card Program page states that consumers can use crypto holdings across 150 million-plus acceptance locations, with real-time crypto-to-fiat conversion so merchants are always paid in fiat. It lists debit-style cards funded by crypto and stablecoins, crypto-backed credit, crypto rewards, and self-custody cards. Supported assets on that page include Bitcoin, Ethereum, USDC, and USDT, varying by partner and region. Settlement on the network is still fiat; optional stablecoin settlement is described as available in select markets.

Visa’s stablecoin hub describes the same shape from the other network: stablecoin-linked cards connect wallets to the Visa network so users spend digital assets at millions of merchants. Visa also describes Open USD (OUSD) as open infrastructure it is bringing to market. For a shop, the brand on the plastic matters less than the fact that both major networks already publish a “convert behind the scenes, merchant unchanged” path.

Marqeta’s contribution is the issuing control plane. Its card-issuing platform issues virtual or physical cards, tokenizes them into wallets, and applies spend controls. Expense-management pages describe just-in-time funding: the platform funds only approved transactions at the moment of purchase instead of prefunding a pool. Pair that with a stablecoin balance and the operational picture is: policy engine says yes, zerohash moves or liquidates the token, Marqeta authorizes the PAN, the network settles dollars to the merchant.

zerohash’s contribution is the regulated on-chain side. Its homepage lists $65 billion-plus volume settled, 7 million-plus end customers, 100-plus assets, 200 available jurisdictions, and 99.99 percent uptime. The July 22 release says zerohash already supports instant global payouts for platforms including Gusto and Worldpay, and real-time account funding for Interactive Brokers, Kalshi, and tastytrade. That is payroll, acquiring, and brokerage funding — the same money-movement jobs a small firm already runs — not a trading screen.

Why this showed up now

Three constraints loosened at once: volume, legal characterization, and issuing scale.

Stablecoin volume hit $7.2 trillion in February 2026. According to zerohash, that monthly figure surpassed the U.S. ACH network’s $6.8 trillion in the same month for the first time. The same paragraph says zerohash platform volume grew 690 percent year over year in 2025 and transaction frequency rose 208 percent. Those platform growth figures are repeated in the January 21, 2026 GlobeNewswire report release.

ACH did not shrink. According to Nacha, there were 35.2 billion ACH Network payments in 2025, valued at $93 trillion. According to Nacha’s July 30, 2026 second-quarter release, Q2 2026 volume was 9.3 billion payments valued at $25.9 trillion, up 6.2 percent and 11.1 percent from Q2 2025, with Same Day ACH at 435.7 million payments and $1.3 trillion. The Same Day per-payment cap will rise to $10 million on September 17, 2027, the April 27, 2026 Nacha announcement says, after earlier caps of $25,000, $100,000, and $1 million.

The Federal Reserve describes ACH as the nationwide network for batched credits and debits — payroll, tax refunds, mortgages, utility bills — operated by the Reserve Banks and the Electronic Payments Network. FedNow went live on July 20, 2023 as a 24x7x365 instant interbank service. Federal Reserve Bank Services publishes participant lists and 2026 fees for that rail. Instant bank payments exist. They still require a deposit account at a depository institution. Stablecoin-backed cards are an attempt to give token balances the same tap-to-pay surface without waiting for every supplier to join FedNow.

Legal characterization moved in parallel. On April 4, 2025, the SEC Division of Corporation Finance stated that the offer and sale of “Covered Stablecoins” — USD-referenced, 1:1 redeemable, backed by low-risk liquid reserves at or above redemption value — do not involve the offer and sale of securities under the Securities Act or Exchange Act as described in that statement. Circle, issuer of USDC, points at that statement on its USDC product page and says its view is that USDC is a Covered Stablecoin.

On the bank-charter side, according to the OCC’s August 19, 2026 release, Comptroller Jonathan V. Gould said 23 of 40 de novo charter applications received since President Trump took office involve some form of digital-asset activity, an eightfold increase from the prior four years, and that the OCC would have a final GENIUS Act rule out by November. The OCC homepage is the parent for that release. That is a supervisor talking about payment stablecoins as a new industry, not a sandbox experiment.

Money-transmitter rules were never absent. FinCEN’s March 18, 2013 guidance FIN-2013-G001 says a user who obtains convertible virtual currency to buy goods or services is not a money services business, while an administrator or exchanger that accepts and transmits convertible virtual currency is a money transmitter unless an exemption applies. That is why a shop spending USDC at Home Depot is not expected to register as an MSB, and why the platform that converts the token for the card is.

The dollars sitting behind the card

USDC is the digital dollar most often named in this design. Circle’s USDC page reports $73.3 billion of USDC in circulation as of 31 August 2026, with $73.6 billion of USD in reserves the same day, 100 percent backed by cash and cash equivalents, and native issuance on dozens of chains. The FAQ on that page lists 35 blockchain networks as of June 29, 2026. All-time volume is stated as $98.3 trillion. USDC is described as redeemable 1:1 for U.S. dollars.

Circle’s transparency page repeats the August 31, 2026 balances: $73.3 billion in circulation, $73.6 billion total reserves, and 30-day mint/burn of $34.2 billion issued and $32.8 billion redeemed. The majority of the reserve sits in the Circle Reserve Fund (USDXX), an SEC-registered 2a-7 government money market fund, with daily portfolio reporting via BlackRock. Deloitte & Touche LLP is named as Circle’s independent auditor since fiscal 2022. Circle’s license page identifies Circle Internet Financial, LLC as NMLS ID 1201441, a New York money transmitter and Virtual Currency Business Activity licensee, with a Bermuda Monetary Authority license for Circle International Bermuda Limited.

Circle’s 2025 State of the USDC Economy said USDC circulation grew more than 78 percent year over year into early 2025, monthly transaction volume reached $1 trillion in November 2024, all-time volume had surpassed $18 trillion by then, and USDC was accessible to more than 500 million end-user wallet products. Those 2024–2025 figures are older than the August 2026 circulation print; use the later transparency numbers for current stock, and the report for the earlier run-rate.

PayPal’s dollar token is a second stock of spendable digital dollars. PayPal USD (PYUSD) is described as redeemable 1:1 for U.S. dollars, issued with custody by Paxos Trust Company, with 4 percent rewards for PYUSD held in the PayPal app as of the page’s current rate, and a path to about 70 markets. U.S. merchants can accept PYUSD where PayPal checkout is available. PYUSD is not legal tender and is not a deposit. For a clinic already collecting PayPal, that is a parallel digital-dollar balance that a future card program could, in principle, point at — a product decision for PayPal and its issuer, not a claim that PYUSD already rides Marqeta.

Who holds the licenses

zerohash’s U.S. license schedule, updated June 3, 2026, lists money-transmitter and related licenses state by state, including New York money transmitter MT 104418 and New York Virtual Currency Business Activity Company License 0000017 under the New York State Department of Financial Services. The July 22 press release says zerohash llc, NMLS ID 1699379, is licensed as a money transmitter, that zerohash llc and zerohash liquidity services llc are licensed for Virtual Currency Business Activity by NYDFS, that the firm operates regulated entities in 51 U.S. jurisdictions, and that it is not registered with the SEC or FINRA. Services may not be available in all jurisdictions.

Marqeta is a public card-issuing platform, not a bank. Its homepage and investor relations site describe embedded finance and modern card issuing, with Q2 2026 earnings materials posted. Expense-management copy states Marqeta is not a bank or a lender and that it provides a technology platform so customers can build products using bank-partner services. A small shop does not become a card issuer by using a Marqeta-powered app; the fintech or bank program manager does.

Mastercard’s newsroom listed, as of the August 2026 page, a May 27, 2026 item that Mastercard was granted a New York DFS BitLicense and an August 3, 2026 item that Mastercard completed the acquisition of BVNK to advance global stablecoin capabilities. Those headlines sit on the newsroom index; they show networks buying and licensing the same conversion layer that Marqeta is renting through zerohash.

How U.S. noncash payments actually look

According to the Federal Reserve Payments Study top-line for 2015–2024, U.S. noncash payments reached 236.6 billion in 2024 with a value of $140.01 trillion. Cards were 187.7 billion payments and $11.50 trillion. Debit cards were 120.6 billion and $4.99 trillion. Credit cards were 67.1 billion and $6.51 trillion. ACH was 39.7 billion and $104.06 trillion. Checks were 9.2 billion and $24.45 trillion. Average values were $61 for cards, $41 for debit, $97 for credit, $2,622 for ACH, and $2,653 for checks.

Source: Federal Reserve Payments Study, CY 2015–24 top-line, released July 2026. Parent study page: FRPS.

That table is why a stablecoin that only moves on-chain cannot replace a shop’s card. ACH holds the value. Cards hold the count. Stablecoin-backed card programs are a bid to attach token value to card count. Federal Reserve payment-systems pages still list FedACH, FedNow, Fedwire, checks, and Regulation II debit interchange as the official U.S. map. Token cards sit beside that map, not on it, until an issuing bank and a network BIN say otherwise.

Timeline of the spendability build

Sources: linked in the Event column; FinTech Global corroborated the partnership on July 27, 2026.

According to zerohash’s January 21, 2026 report release, the firm estimated more than 1.4 billion Stablecoin-Ready Accounts globally, said active stablecoin customers on its platform rose 146 percent year over year, inbound RFIs rose 5 times from 2024 to 2025, average transaction size rose 157 percent, active users spanned 106 countries, non-U.S. customers grew 422 percent, and mentions of “stablecoin” in SEC EDGAR filings rose more than 290 percent. The report landing page repeats the 1.4 billion SRA estimate, 146 percent active-usage growth, 690 percent volume growth, 106 countries, and 2,000-plus public-company filing mentions (a 290 percent increase). It also states zerohash received MiCAR authorization in November 2025.

USTA analysis: one month of tokens versus a year of cards

USTA analysis uses only the figures already cited above. Inputs: February 2026 stablecoin monthly volume of $7.2 trillion and U.S. ACH monthly volume of $6.8 trillion from the zerohash–Marqeta release; Marqeta 2025 payments volume of nearly $400 billion from the same release and Marqeta.com; USDC circulation of $73.3 billion and reserves of $73.6 billion as of August 31, 2026 from Circle.

USTA analysis. Inputs: zerohash; Marqeta; Circle transparency. Marqeta’s $400 billion is the release’s “nearly $400 billion,” so the 5.6 percent share is approximate.

The 5.6 percent line is the operational punchline. A modern issuing platform that already runs at nearly $400 billion a year is still only about one-eighteenth of a single month of reported stablecoin turnover. Token volume is not the same as card spend — a large share of stablecoin prints is exchange hop, treasury rotation, and same-wallet noise — but the gap shows why issuers want a card front-end: the money is already moving on-chain, and it is not yet showing up as $41 average debit tickets at U.S. merchants.

The 100.4 percent coverage line is a snapshot, not a guarantee. It says that on August 31, 2026, Circle’s published reserve print exceeded published circulation by $0.3 billion. It does not say a card program is insured, and it does not say every token a program might support is USDC.

Honest limits

The partnership is an announcement. The July 22 release includes a Private Securities Litigation Reform Act safe-harbor paragraph. Availability will vary by jurisdiction. zerohash accounts are not FDIC or SIPC protected. zerohash is not registered with the SEC or FINRA. Enablement of an asset is not an endorsement.

Mastercard’s crypto-card explainer flags spread: even when an issuer advertises zero transaction fees, the difference between market price and the price at which the issuer sells the asset can act as a hidden cost. For a floating crypto that matters a lot. For a 1:1 dollar token it should be smaller, but FX, weekend liquidity, and chain-selection still sit in the program manager’s fee schedule, which this announcement does not publish.

Circle Mint, on the USDC page, is for institutions; it is not available to individuals or small businesses. Shops access USDC through exchanges, neobanks, wallets, and Circle Alliance on/off-ramps. A two-truck firm cannot mint $73 billion of USDC. It can hold a float and spend it if a card program points at that float.

Programmable spend controls still need a human policy. Marqeta documents granular MCC locks, velocity rules, and JIT funding. Those tools do not decide whether a technician’s Home Depot tap is a job cost or a personal TV. That decision is the same executive-assistant and receipt workflow a shop already needs on a fiat card.

Fleet and field businesses should not confuse a spendable token with an ELD, a TMS, or a dispatch system. A small-fleet ELD shortlist and an AscendTMS vs McLeod workflow still sit on the operations side. The card only pays the fuel desk. Logistics automation is a separate rail.

Where this plugs into a shop’s existing stack

If a 10-person agency already pushes approved spend into a ledger from card webhooks, a stablecoin-backed PAN is another webhook. The bookkeeper still wants merchant name, MCC, amount, tax, and job code. Shops that already route receipts through US Tech Automations can add that authorization feed as one more event source instead of standing up a new expense product.

A finance-accounting agent at US Tech Automations can match those events to invoices and job codes the same way it matches a conventional virtual card. The small-business automation survey is the right companion page for that wiring, because the bottleneck is coding and close, not the brand on the plastic.

Home stays the index for those workflow products. Do not rebuild the card program in-house. Do not become a money transmitter. Do not treat a token wallet as a payroll account without reading the program’s own disclosures.

Signal vs Speculation

Demonstrated fact (sourced): On July 22, 2026, Marqeta and zerohash announced a partnership to put stablecoin balances behind Marqeta-issued cards, with merchants paid in fiat. Marqeta processed nearly $400 billion in 2025 and is certified in 40-plus countries. zerohash reports 51 U.S. jurisdictions, NYDFS virtual-currency licensing, and NMLS 1699379. February 2026 stablecoin monthly volume was cited at $7.2 trillion versus $6.8 trillion ACH. Nacha printed 35.2 billion ACH payments and $93 trillion in 2025, and 9.3 billion / $25.9 trillion in Q2 2026. The Fed counted 236.6 billion U.S. noncash payments and $140.01 trillion in 2024, with cards at 79 percent by number. USDC circulation was $73.3 billion against $73.6 billion reserves on August 31, 2026. The SEC staff statement of April 4, 2025 describes Covered Stablecoins as outside the securities offer-and-sale construct it analyzed. The OCC said in August 2026 that 23 of 40 recent charter applications involve digital assets and that a GENIUS final rule was due by November. Visa and Mastercard both publish stablecoin- or crypto-linked card programs that convert to fiat before merchant settlement. FedNow has been live since July 20, 2023. FinCEN’s 2013 guidance still treats administrators and exchangers as money transmitters and ordinary users as not MSBs.

Our read (12–36 months, small and mid-size firms): If Marqeta actually ships the zerohash integration into the same expense-card APIs that platforms like Ramp already use, then a two-truck HVAC shop will not “adopt stablecoins.” Its parts card will simply debit a digital-dollar float the owner already received from a property-management client. The merchant of record at the supply house will not know. The change that matters is working-capital: overnight and weekend balances can sit in a 1:1 token and still tap on Saturday, which ACH batch windows and many bank apps still cannot match as cleanly as a card.

Our read on who feels it first: Cross-border agencies, clinics that already take PayPal or USDC from overseas patients, and fleets that get paid by brokers in dollars but buy fuel in the U.S. Those firms already hold two balances. A card that spends the token balance removes the Tuesday-morning wire. Domestic shops that only ever see ACH payroll have less reason to switch.

Our read on what will not happen: Merchants will not flip terminals to “accept USDC” as a mass movement in this window. The Mastercard explainer is explicit that conversion happens outside the network. FedNow and Same Day ACH, especially after the $10 million cap in 2027, will keep winning large B2B invoices. Token cards will compete for the $41 debit ticket, not the $2,622 ACH average.

Our read on risk the press release underplays: Spread, chain outages, issuer-processor outages, and the fact that token balances are not deposits. A clinic that parks payroll in USDC because Circle’s print shows 100.4 percent coverage still has no FDIC ticket if the program manager, custodian, or token issuer fails. GENIUS-rule timing at the OCC is a forecast inside Gould’s remarks, not a live rule as of this writing.

Our read on workflow: Teams that already run document and spend routing on US Tech Automations will plug a live stablecoin card in as a model swap on the same authorization topic, not as a new company. The unglamorous work — MCC locks, job-code mapping, receipt photos — stays the product.

FAQs

What are stablecoin-backed card programs?

Stablecoin-backed card programs are card products that spend a digital-dollar token at a normal merchant terminal while the merchant is paid in ordinary local currency. Marqeta and zerohash used that exact phrase in the July 22, 2026 announcement when they described multinational programs built on Marqeta issuing plus zerohash custody and liquidity.

Do merchants have to accept crypto?

No. Mastercard and the Marqeta–zerohash release both say the merchant is paid in fiat through existing networks. The conversion sits with the issuer and the crypto infrastructure partner, not with the terminal.

Are balances in these programs FDIC insured?

No. The zerohash disclosures in the partnership release state that zerohash accounts are not subject to FDIC or SIPC protections, or equivalent protections outside the U.S. Circle and PayPal also state that USDC and PYUSD are not deposit accounts.

When did Marqeta and zerohash announce this?

July 22, 2026, in a zerohash press release, with a FinTech Global write-up on July 27, 2026. The releases describe a collaboration that will enable spend, not a completed nationwide rollout.

How is this different from a crypto rewards credit card?

A rewards crypto card, as Mastercard describes, borrows fiat and pays the holder a crypto rebate. A stablecoin-backed debit-style program spends a token balance you already hold. One is credit with a crypto kicker. The other is a spendable digital-dollar wallet with a card on the front.

Why should a two-truck shop care if ACH already works?

ACH is the value rail: Nacha counted $93 trillion in 2025, and the Fed put ACH at $104.06 trillion in 2024. Cards are the count rail: 187.7 billion payments. If a client pays you in USDC at 9 p.m. Saturday, ACH cannot tap the supply house at 9:05. A card can, if the program is live and the balance is there.

What happens if the token is not USDC?

The Mastercard program page lists Bitcoin, Ethereum, USDC, and USDT among supported assets, varying by partner. Floating assets add spread and volatility at the moment of sale. A dollar token with a published 1:1 reserve print is the conservative case; it is still not a bank deposit.

Glossary

• Stablecoin-backed card programs: Card products that debit a digital-dollar (or other stable-value) token and still settle the merchant in fiat on existing card networks.

• USDC: A dollar-referenced stablecoin issued by Circle affiliates, described as 1:1 redeemable and fully reserved, with circulation of $73.3 billion as of 31 August 2026.

• Covered Stablecoin: The SEC Division of Corporation Finance term for a USD 1:1, fully reserved, payment-and-store-of-value token whose offer and sale, as described, are not treated as securities transactions.

• Card issuing: The bank-and-processor stack that creates PANs, sets spend controls, and connects to Visa or Mastercard; Marqeta’s product is one such platform.

• Just-in-time (JIT) funding: Authorizing and funding a card transaction only when the purchase is approved, instead of preloading a pool; described on Marqeta’s expense pages.

• ACH: The U.S. Automated Clearing House network governed by Nacha and operated in part by the Federal Reserve, used for payroll, bills, and B2B credits and debits.

• FedNow Service: The Federal Reserve’s 24x7x365 instant payment service, live since July 20, 2023, for depository institutions.

• Money transmitter: Under FinCEN FIN-2013-G001, an administrator or exchanger of convertible virtual currency that accepts and transmits value; a shop using a card to buy parts is a user, not an MSB, under that guidance.

What to do with the announcement

Read the primary release, not a recap, and ask any expense-card vendor two questions: which token, and which disclosure applies to the balance. If the answer is USDC, read Circle’s current circulation and reserve print. If the answer is a floating asset, read the spread language on Mastercard’s crypto-card page.

Keep merchant-facing checkout alone. The entire design is that the supply house does not change. Put the work on authorization webhooks, MCC locks, and job-code matching — the same close process a shop already owes its accountant.

When a program is live, map those card events into an agentic workflow instead of standing up a second ledger. US Tech Automations can sit on the webhook side of that spend once a program is live. That is a routing job, not a new bank.
