Stablecoins in Everyday Payments: From Digital Dollar Balances to Retail Checkout
Stablecoins are increasingly being connected to ordinary payment journeys: a shopper can authorize a wallet payment at online checkout, a cardholder can spend against a stablecoin balance, and a business can settle a cross-border invoice without making the recipient hold crypto. Yet the sensible thesis is narrower than the headlines: stablecoins are becoming a useful additional payment rail and settlement asset, not a replacement for cash, bank deposits, or card networks. Their clearest near-term role is to move value—often dollar-denominated value—across borders and between digital platforms while familiar providers handle conversion, compliance, and merchant acceptance.
The distinction matters because on-chain scale does not equal household spending. Visa’s live analytics materials reported more than $272 billion of fiat-backed stablecoin supply and $51 trillion in raw transfer volume over the preceding 12 months, falling to $10.2 trillion after its adjustments for duplicated and noisy activity.1 Those numbers show a sizeable infrastructure, but not a retail-sales figure. A study of Ethereum transfers found more than $4 trillion of raw monthly stablecoin transfers, whereas transactions below $250 were about $6 billion monthly; smart-contract activity represented 53.2% of volume in a July 2025 sample.2 Transfers between exchanges, automated contracts, treasury movements, bridges and market trading are economically important, but they are not someone buying lunch.
Payment-specific estimates point to genuine, still limited use. McKinsey and Artemis estimated approximately $390 billion in annualized stablecoin payments in 2025, or about 0.02% of global payments; their model attributed the largest component to business-to-business payments, followed by payroll and remittances.3 Stablecoin-linked card spending was estimated at $4.5 billion for 2025.3 These are modeled estimates rather than a complete census, and their assumptions—especially when classifying treasury-provider activity—should temper certainty. The practical story is therefore one of selective adoption: useful in particular corridors and workflows, but far from ordinary universal retail tender.
A payment asset with a qualification built into its name
A stablecoin is a cryptoasset designed to maintain a reference value, commonly one US dollar, through reserves and an issuer’s redemption promise. Most current supply is dollar denominated: the Bank for International Settlements (BIS) states that more than 99% of stablecoins are tied to the US dollar.4 This can be attractive where people or firms seek digital access to dollars, face costly foreign-exchange conversion, or want payments outside bank operating hours.
“Stable,” however, describes an objective, not an unconditional guarantee. A token’s market price, its redemption liquidity and the value it delivers in a shopper’s local currency can all depart from expectations. Confidence depends on the issuer, the composition and custody of reserves, legal redemption rights, operational continuity, and the liquidity of the markets through which users enter and exit. A payment product should explain that distinction as clearly as it states the exchange rate.
Stablecoins initially served crypto markets as a way to move between cryptoassets and a dollar-like unit.1 Retail use tends to be viable only when that origin is hidden behind a better experience: a checkout provider converts the merchant’s proceeds to bank money, a card program converts at the point of sale, or a remittance app lets the recipient cash out. In these arrangements, the token may travel in the background while the payer and payee use a recognizable application or card.
How a typical stablecoin checkout works
Consider an online merchant that offers a USDC option through a payment service provider. The customer sees the invoice in local currency or dollars, chooses the stablecoin option, and connects or opens a compatible wallet. The provider presents the amount, the accepted network and the destination; the customer authorizes the transaction in the wallet. The transaction is broadcast to the relevant blockchain, where the merchant or provider waits for the confirmation policy it has chosen. That policy is a commercial risk decision: more confirmations generally reduce reversal risk but can delay a final fulfilment signal.
The merchant need not receive tokens. In Stripe’s announced Shopify arrangement, merchants in 34 countries were to be able to accept USDC on Base while receiving their preferred local currency in a bank account by default; accepting USDC into an external wallet was an option.5 In that design, the processor manages the wallet and conversion complexity, while the merchant continues to reconcile a payout in its usual currency. Stripe later announced support for recurring stablecoin payments, showing how providers are attempting to extend the same model beyond one-off purchases, although an announcement alone does not demonstrate uptake or coverage in every market.6
The customer’s steps are more unfamiliar than a card tap. They must have the right wallet, sufficient token balance, the network’s native token or a sponsored-fee arrangement where applicable, and confidence that the address and amount are correct. Once a normal blockchain transfer has been confirmed, it is generally not reversible in the way a card authorization may be. A provider may offer customer support or a refund process, but that is a service rule, not a technical recall of the transfer.
Stage | Wallet checkout with conversion | Stablecoin-linked card |
Customer action | Selects a stablecoin method and approves in a wallet | Taps, inserts, or enters a card as usual |
Asset initially spent | A stablecoin, such as USDC | A stablecoin balance backing the card program |
Merchant receives | Local bank currency by default, or stablecoin if elected | Local fiat through the existing card acceptance flow |
Main complexity holder | Wallet user and payment processor | Card issuer/program manager and processor |

A card-linked route changes the user experience more radically than it changes the merchant’s. Visa describes programs in which the cardholder spends from a stablecoin balance, Bridge deducts stablecoin and converts it to fiat, and the merchant is paid through Visa’s established rails.7 The merchant’s card terminal is not necessarily processing an on-chain stablecoin payment. This is an important analytical distinction: network reach signals potential acceptance through conversion, not direct acceptance of a given token at every shop.
Where the payment case is strongest
For international businesses, stablecoins can reduce steps between a sender who holds digital dollars and a recipient who wants to receive or convert value in another jurisdiction. That can matter for supplier invoices, platform payouts, remote contractors, and remittances. Stripe announced stablecoin-powered accounts in 101 countries that could receive funds via crypto and conventional rails and send supported stablecoins, initially USDC and USDB.8 Deel describes an employer-funding route in USDC for global payroll, with contractor withdrawals in more than 150 currencies.9 These are provider accounts of their own products, not independent proof of lower costs in every route; local availability, foreign-exchange spreads, withdrawals and compliance checks determine the final result.
Money transfer illustrates both the opportunity and the constraint. MoneyGram’s wallet guidance says users can request, receive, hold, send and withdraw USDC; a cash withdrawal requires a selected location, identification and completion within 24 hours. It also says that blockchain transfers are instant and irreversible, while wallet-to-wallet availability and cash services vary by country.10 Stablecoins may make the middle of a transfer faster, but the beginning and end remain subject to onboarding, liquidity, identity checks and the local cash-out network.
For merchants, potential advantages are not simply lower fees. On-chain rails can operate continuously, provide a programmable record of transfer, and offer quicker access to funds for businesses accustomed to delayed cross-border settlement. A 2024 Fireblocks case study reported that Worldpay used its infrastructure for 24/7/365, T+0 merchant settlement; the performance claims are vendor-reported and should not be generalized beyond the cases described.11 The relevant comparison is not “blockchain versus nothing,” but a route-specific comparison of acceptance fee, conversion spread, settlement timing, refund needs, working-capital value and fraud cost.
For users in countries with constrained access to dollar accounts, a dollar-linked balance can have a different appeal from a faster checkout button. BIS notes growing cross-border use, particularly among emerging-market residents seeking dollar access.4 That access can also create policy concerns: widespread use of a foreign-currency stablecoin may weaken the role of local money and contribute to stealth dollarization.4 A payment convenience for an individual may have macroeconomic consequences when applied at scale.
Limits and risks that cannot be designed away
The first limit is acceptance. A stablecoin is not useful for routine purchases if the customer cannot spend it widely and the merchant sees no economic reason to accept it. Card-linked programs can solve this by retaining card rails, but in doing so they introduce issuer, processor and conversion dependencies. Direct wallet acceptance avoids some intermediaries yet makes the user manage networks, keys, addresses and transaction fees. Fragmented blockchains also present interoperability and operational-resilience questions; Federal Reserve Governor Christopher Waller has noted that it remains unclear how competing ecosystems and interoperability will shape viable business models.12
The second is money and redemption risk. The President’s Working Group warned that failure to honor redemption, or loss of confidence in redemption, could trigger a run and harm users and the broader system.13 A stablecoin user therefore bears risks unlike those of simply holding a bank deposit or currency note: issuer failure, reserve quality, custodian disruption, smart-contract flaws, wallet compromise and loss of access to an exchange or off-ramp. Product disclosures should state who owes redemption, in what currency, through which venue, at what fee and under what delay.
The third is consumer protection. Address errors, phishing, malware and social engineering can turn an irreversible transfer into a permanent loss. A merchant may choose to refund a customer, but it cannot compel an unknown recipient wallet to return funds. In the United States, the Consumer Financial Protection Bureau sought comment in 2025 on how the Electronic Fund Transfer Act and Regulation E could apply to emerging payment mechanisms, including stablecoins; that proceeding does not establish that every stablecoin transaction has the same error and fraud protections as a conventional account transfer.14 Rights depend on the provider, product, jurisdiction and final legal interpretation.
The fourth is privacy and compliance. Public blockchain activity can expose transaction patterns, while wallets and payment applications can collect identity, device and behavioral data. The CFPB has cautioned that modern digital-payment data practices may go beyond what is necessary to execute a payment and can create surveillance or personalized-pricing concerns.14 At the same time, financial institutions must meet anti-money-laundering, sanctions and travel-rule obligations. FATF calls for licensing or supervision of virtual-asset service providers, customer due diligence, record keeping, suspicious-transaction reporting and secure originator/beneficiary information transfer.15 Compliance may make a retail service safer and more lawful, but it also reduces the fiction that regulated stablecoin payments are anonymous, frictionless cash.
Finally, the economics are unsettled. A user may face spread and fees when buying, bridging, sending, swapping or withdrawing tokens; a merchant may face provider fees, treasury controls and accounting work. Network congestion and outages can add uncertainty. Savings must be demonstrated for a specified currency pair, transaction size and payout method—not inferred from the existence of a blockchain.
Regulation is becoming a prerequisite, not an afterthought
Policymakers broadly agree on the risk categories, even though rules differ across jurisdictions. BIS identifies licensing, reserve management, redemption rights, capital, governance, cybersecurity, consumer protection and anti-money-laundering controls as central to a credible framework.16 The Financial Stability Board has called for proportionate supervision, cross-border cooperation and a “same business, same risk, same rules” approach before global stablecoin arrangements operate.17 These principles matter because an everyday payment can involve an issuer, reserve custodian, wallet provider, exchange, blockchain validator set, payment processor and merchant—all of whom can introduce a point of failure.
Legal status should be reported precisely. In the supplied U.S. legislative material, S.394, the GENIUS Act of 2025, was introduced on 4 February 2025; its proposed provisions included permitted-issuer requirements and one-to-one reserves in specified assets.18 That source describes a bill, not proof of enactment. Businesses should verify the current law and licensing obligations in each jurisdiction before launching a product or making claims about consumer rights. Regulation can support adoption by clarifying reserves and redemption, but it will not eliminate operational failures, fraud, or foreign-exchange risk.
A measured conclusion
Stablecoins have moved beyond their original role as trading collateral. They can make a useful contribution where cross-border dollar access, continuous settlement or programmable disbursement solves a real problem. The most plausible route into day-to-day commerce is not a sudden replacement of cards and bank accounts. It is integration: wallets at selected checkouts, cards that convert balances behind the scenes, and payment providers that settle merchants in their chosen currency.
That route is also why claims of mass retail adoption deserve scrutiny. Large on-chain totals mostly describe a broader set of financial and technical activity than consumer purchases. The test for an ordinary payment method is practical: transparent all-in cost, reliable conversion and redemption, meaningful dispute handling, broad acceptance, compliant access, and a user experience no harder than the option it seeks to supplement. Stablecoins can meet parts of that test today in particular markets. Meeting all of it consistently will require resilient infrastructure and enforceable rules as much as faster token transfers.
