Welcome to USD1usecase.com

This page explains what people usually mean when they talk about a use case for USD1 stablecoins. Here, USD1 stablecoins means any digital token designed to stay redeemable at a one-to-one value with U.S. dollars. The phrase is descriptive, not a brand claim, and the goal is educational rather than promotional.

A real use case is not just a clever demo. It is a situation where USD1 stablecoins solve a practical problem better than the available alternatives after speed, cost, safety, legal clarity, and user effort are all considered. That standard matters because stablecoins can look impressive in screenshots while falling apart in day-to-day use. Recent work from the International Monetary Fund, the Bank for International Settlements, the Federal Reserve, the Financial Stability Board, the Financial Action Task Force, the European Central Bank, and the World Bank all point to the same broad conclusion: stablecoins may improve some payments and settlement flows, but the benefits depend heavily on redemption design (how and on what terms a holder can exchange back for U.S. dollars), reserve quality (the safety and liquidity of the assets held to support redemption), governance (who makes decisions and who is accountable), and compliance (following legal and regulatory rules). They also come with meaningful risks that do not disappear just because the price is intended to stay at one U.S. dollar.^[1]^[2]^[3]^[4]^[5]^[6]^[8]

What a use case really means

When people say that USD1 stablecoins are useful, they can mean very different things. One person may mean "I can move value on a weekend." Another may mean "I can settle a trade without waiting for a bank wire." Someone living in a high-inflation economy may mean "I can hold a digital claim that tracks the U.S. dollar instead of my local currency." A merchant may mean "I can receive money from another country without the old chain of correspondent banks (banks that help move money across borders for other banks)." Those are not the same need, and they should not be judged by the same yardstick.

The cleanest way to think about a use case is to ask six questions. First, what job is the payment or asset supposed to do? Second, what is the realistic alternative: cash, a domestic instant-payment rail, a card network, bank wires, or a money transfer company? Third, who bears the operational burden, meaning the daily work and failure risk of running the system? Fourth, what legal claim does the holder actually have when redeeming for U.S. dollars? Fifth, what happens if the user loses access credentials, meaning the secret information needed to authorize transfers? Sixth, which costs are visible and which only appear at the edges, such as conversion fees, wallet fees, or delays at the off-ramp, meaning the service that converts digital assets back into bank money? Here, wallet means software or hardware that stores access credentials and helps a user send or receive digital assets.

Those questions are important because the public story around stablecoins often starts with speed and ends there. Yet payment systems succeed or fail on a larger bundle of features. The Federal Reserve discussion of digital money highlights that any modern payment option must be evaluated against safety, efficiency, privacy, and the ability to combat illicit finance. The BIS and FSB add that the same economic activity should face the same level of regulation when it creates the same risks. In other words, a transfer that looks new on a blockchain, meaning a shared digital ledger that records transactions, is not magically free from the old questions about finality, liquidity, governance, dispute handling, consumer protection, and financial crime controls. Finality means the point at which a payment is effectively irreversible. Liquidity means ready access to spendable funds without major delay or discount.^[2]^[4]^[5]^[9]

For USD1 stablecoins, that means the strongest use cases are usually the ones where the advantages of digital transfer are obvious and the weak points have already been addressed. If a use case depends on ignoring reserve transparency, brushing aside local law, or assuming every user can safely manage secret keys, meaning the private access codes that authorize spending, it is not a strong use case. It is a fragile one.

The most established use case today

The most established use case for stablecoins in general is still inside the broader digital-asset market, meaning markets built around blockchain-based assets. The BIS annual report says stablecoins were designed as a gateway to the crypto ecosystem, meaning services and markets built around digital assets, and notes that they have served as on- and off-ramps, meaning a way to move into or out of digital-asset activity while keeping a value linked to government money. The IMF likewise states that recent issuance growth has been driven largely by use in crypto trades, even though future demand could come from other applications if legal and regulatory frameworks mature. The ECB has made a similar point by describing stablecoins as digital units of value that can support trading and other crypto-market functions while also bringing risks that resemble those of payment instruments and financial assets at the same time.^[1]^[2]^[8]

That matters for USD1 stablecoins because it sets a baseline. If someone asks, "What are USD1 stablecoins for right now?" the most accurate answer is still "often for moving between cash-like digital value and other digital assets." This includes collateral, meaning assets posted to secure an obligation, trading balances, and settlement inside digital-asset venues. That may sound narrower than the marketing language around global payments, but it is honest. An educational guide should start with the use case that is most evidenced before moving to the use cases that are promising but still uneven.

There is nothing inherently wrong with this first use case. In fact, it solves a real problem for market participants who want less price volatility than more volatile digital assets that are not supported by redeemable reserves. A trader, fund, or market-making firm, meaning a trading firm that continuously quotes buy and sell prices, can keep working capital, meaning money needed for day-to-day operations, in USD1 stablecoins without constantly exiting to the banking system. Transfers can happen at all hours, and balances can move between venues faster than many traditional bank payment channels allow. But even here, the value of USD1 stablecoins depends on trust in redemption, reserve assets, governance, and the relevant network. Reserve assets means the cash and short-term instruments held to support redemptions. A unit that is easy to transfer but hard to redeem is not doing the full job. A unit that trades at face value most days but loses the peg under stress has only partial usefulness. The BIS, ECB, and IMF all stress that the quality of the reserve pool and the ability to meet redemptions in full are central to whether a stablecoin is credible.^[1]^[2]^[8]

This first use case also explains why the debate can sound confused. Some people discuss USD1 stablecoins as if they are already a mainstream replacement for bank deposits. Others discuss them as if they are only casino chips for speculative markets. Both views are incomplete. Stablecoins clearly have real utility in digital-asset settlement today, but that does not prove they are always the best tool for household payments or everyday commerce. A balanced page about USD1 stablecoins should keep that distinction clear.

Cross-border payments and remittances

Cross-border payments are where many people see the most intuitive real-world potential for USD1 stablecoins. The appeal is straightforward. Public blockchains do not close on weekends, they can move balances between jurisdictions without waiting for bank cut-off times, and they may reduce the number of intermediaries in the chain. The BIS Committee on Payments and Market Infrastructures has examined this possibility in detail and acknowledges that stablecoin arrangements could help address some cross-border frictions. At the same time, the same report warns that the drawbacks may outweigh the benefits unless the arrangement is properly designed, properly regulated, and fully compliant with relevant requirements. It also emphasizes that no arrangement had yet met that full standard when the report was published.^[3]

Why is this use case attractive in the first place? Because the existing system is often expensive and slow for small transfers. The World Bank's Remittance Prices Worldwide database reported that the global average cost of sending remittances was 6.49 percent in the latest March 2025 update. For a worker sending money home every month, that level of friction is not abstract. It directly lowers the value received by the family at the other end. If USD1 stablecoins can reduce some of that cost, especially on specific country pairs, often called corridors, where the legacy system is weak, the use case is economically meaningful.^[7]

Still, the phrase "can reduce" matters. It does not mean "always reduces." In a real remittance flow, the sender may need to buy USD1 stablecoins, pay a network fee, send them, and then the recipient may need to convert them into local currency or spend them directly. If either edge of that flow is expensive, inconvenient, or legally restricted, the headline advantage disappears. A cheap blockchain transfer in the middle does not guarantee a cheap end-to-end remittance. In some countries, the recipient may prefer a domestic instant-payment rail once the money is inside the banking system. In others, local rules around foreign currency, reporting, or crypto services can introduce delays or risks that traditional money-transfer providers already know how to handle. The BIS, IMF, and FSB all stress that use cases should be assessed on the full chain, not just on the transfer layer.^[1]^[3]^[5]

There is also a policy dimension. The BIS annual report and the IMF both note that wider use of U.S. dollar stablecoins in economies with inflation or limited dollar access can lead to currency substitution, meaning residents start relying on the U.S. dollar rather than the local currency for payments and savings. From the user's perspective, that may feel rational. From the state's perspective, it can weaken monetary sovereignty, meaning the ability of local authorities to influence domestic financial conditions through their own currency and institutions. So, a remittance use case can be socially helpful for one family while still raising system-level concerns for policymakers.^[1]^[2]

The practical lesson is that cross-border payments are one of the strongest candidate use cases for USD1 stablecoins, but only when viewed as a complete end-to-end country-pair problem. The strongest examples usually combine reasonably priced entry and exit services, clear redemption rights, enough compliance to keep the flow legitimate, and a recipient who actually benefits from receiving digital dollars rather than local bank money. Without those pieces, "cross-border" becomes a slogan instead of a working model.

Online commerce and merchant settlement

Another credible use case for USD1 stablecoins is merchant settlement, especially for online businesses that sell internationally, operate around the clock, or serve customers who have limited card access. The value proposition is easy to understand. A merchant can receive a dollar-linked digital instrument without waiting for multi-day settlement windows, without depending on card authorizations, and without taking direct exposure to the volatility of a more volatile digital asset. For some merchants, especially digital-first businesses, that can improve cash visibility and reduce the uncertainty that comes from long settlement chains.^[1]^[2]

But this use case has caveats that are often omitted in optimistic sales copy. Merchant payments are not just about receiving money. They are also about refunds, disputes, chargebacks, meaning forced payment reversals initiated through card networks, recordkeeping, tax reporting, and customer support. Traditional card systems are costly, but they bundle dispute processes and consumer protections that many customers have come to expect. A transfer of USD1 stablecoins may be fast, yet finality can be more complicated than it first appears. Network confirmation rules differ. Mistaken payments can be hard to reverse. Fraud losses may land on the user or merchant rather than on an intermediary with a well-known dispute program. CPMI and IOSCO specifically highlight governance, comprehensive risk management, settlement finality, and money settlements as core issues when stablecoin arrangements become important for payments.^[4]^[9]

For that reason, the best merchant use cases for USD1 stablecoins tend to be business-to-business or repeat-customer settings where both sides understand the payment flow and where refunds can be handled operationally even if the underlying transfer is difficult to reverse. A software vendor settling invoices with overseas distributors is different from a consumer-facing shop trying to replace card payments for first-time retail buyers. The first case may benefit from speed and 24-hour settlement. The second may discover that customer support, compliance, and refund logistics matter more than the blockchain rail.

Another factor is total transaction economics. A merchant use case only remains attractive if the cost to accept, move, and redeem USD1 stablecoins stays lower than the realistic alternatives. On some networks, fees are small enough to make this feasible for modest-value payments. On others, the network fee alone can destroy the economics of low-value transactions. This is why serious payment analysis looks at total cost of acceptance, not just the base asset. The Federal Reserve paper on payment evolution, along with BIS and FSB work, supports this broader approach by focusing on safe and efficient payments rather than on technological novelty for its own sake.^[2]^[4]^[5]

So, can USD1 stablecoins work for commerce? Yes, especially where merchants value 24-hour settlement, cross-border reach, and reduced exposure to ordinary crypto volatility. Are USD1 stablecoins a universal replacement for cards, domestic faster payments, or invoicing through banks? No. That claim is too broad. The use case becomes stronger as the transaction becomes more international, more time-sensitive, more digital, and more tolerant of self-service payment mechanics.

Business treasury movement and liquidity

Large businesses care less about slogans and more about treasury movement, meaning how cash and near-cash balances are positioned, mobilized, and settled across entities, partners, and time zones. This is one of the more serious use cases for USD1 stablecoins because the users are often capable of managing operational complexity if the economic gain is clear.^[1]^[2]

Imagine a company with suppliers, contractors, or subsidiaries in several countries. The finance team may need to move U.S. dollar value outside normal banking hours, post collateral to a trading venue, fund a digital-asset operation, or settle a transaction before the next business day in New York, London, or Singapore. In that setting, USD1 stablecoins can function as a 24-hour transfer tool and as a liquidity bridge, meaning a temporary form of dollar-linked value that keeps operations moving while traditional bank channels are closed or slow. The IMF notes that tokenization, meaning the representation of an asset or claim in digital token form, can improve efficiency in payments through increased competition, and the BIS notes that stablecoins can be attractive in cross-border settings because they can move directly between wallets rather than through long chains of intermediaries.^[1]^[2]

This does not mean treasury teams should treat USD1 stablecoins as identical to insured bank balances. The risk profile is different. Treasury use depends on the reserve assets, the legal terms of redemption, the governance of the issuer, the reliability of custodians, and the controls around transfers. Custodian means a professional safekeeper of assets. The FSB framework is useful here because it insists on a "same activity, same risk, same regulation" approach. That principle pushes analysts to ask whether the arrangement is doing bank-like, payment-like, or settlement-like work, and therefore which risk controls should apply. The more systemically important, meaning large enough to matter for the wider financial system, the use case becomes, the less acceptable it is to rely on informal assurances or vague transparency claims.^[5]^[9]

A thoughtful treasury user also asks about concentration risk, meaning dependence on a single issuer, single chain, or single custodian. A payment flow that looks diversified at the surface may still fail if redemption depends on one entity, if the reserve disclosure is too weak, or if the chosen network suffers congestion. The BIS annual report points out that broader stablecoin growth can create interactions with traditional safe-asset markets and can transmit stress through redemption dynamics. That is a reminder that "cash management" with USD1 stablecoins is not only an operational question. It is also a question about how the relevant markets are organized.^[2]

Still, among real-world possibilities, business treasury movement remains one of the more plausible growth areas for USD1 stablecoins. Businesses can absorb some complexity if the gains are clear, especially in markets where time-zone mismatch, bank cut-off times, or weak correspondent banking make ordinary U.S. dollar movement inefficient. In those cases, USD1 stablecoins are not trying to replace every bank function. They are filling a narrow but meaningful gap between the demand for always-on settlement and the reality of legacy infrastructure.

Dollar access and value storage

A different use case appears when USD1 stablecoins are held not mainly for movement, but for access to U.S. dollar value. This is especially relevant in countries where the local currency is unstable, where dollar bank accounts are hard to obtain, or where households and firms want a digital way to keep part of their liquidity in a dollar-linked instrument. The BIS annual report explicitly notes that stablecoins can be appealing in places with high inflation, capital controls, meaning official restrictions on cross-border money movement, or limited access to dollar accounts. The IMF reaches a related conclusion, warning that benefits may coexist with risks of currency substitution and capital-flow volatility, meaning sudden swings in money moving in or out of a country. The ECB has also highlighted the broader macro-financial implications of growing U.S. dollar stablecoin use.^[1]^[2]^[8]

From a household or small-business perspective, this use case is easy to understand. If local money loses value quickly, then holding USD1 stablecoins can feel less like speculation and more like defensive cash management. A street-level importer, freelancer, or saver may prefer a digital dollar claim that can be received quickly, stored in a wallet, and sent onward if needed. In that context, the use case is not abstract finance. It is a response to weak local monetary conditions.^[1]^[2]

Yet this is also where balanced writing matters most. A tool that feels protective at the user level can be destabilizing at the system level. Widespread migration into U.S. dollar stablecoins can shrink the role of local-currency deposits, complicate monetary policy, and weaken the transmission of domestic financial measures. That is why the conversation around USD1 stablecoins often sounds different depending on who is speaking. Users may focus on access and preservation. Authorities may focus on sovereignty, oversight, and spillovers. Both are reacting to real incentives.^[1]^[2]^[5]

There is another practical caution. "Store of value" is not the same as "risk-free cash." If the reserves are weak, the governance poor, or redemption channels narrow, the holder is taking issuer risk, liquidity risk, operational risk, and legal risk. Issuer risk means the possibility that the entity standing behind the asset cannot or will not perform as expected. Operational risk means something goes wrong in systems, custody, or human process. Legal risk means the holder's rights may be uncertain in insolvency, meaning failure to meet obligations, sanctions, or cross-border disputes. The whole point of a stablecoin is stable redeemability. If that is not robust, then the value-storage use case becomes weaker than it first appears.^[1]^[2]^[5]

So, as a value-storage use case, USD1 stablecoins are understandable and in some environments genuinely useful. But they are not equivalent to cash in a bank account, not equivalent to sovereign money, and not equally suitable across all jurisdictions. The strongest statement is not "USD1 stablecoins are the future of savings." It is "USD1 stablecoins may provide practical dollar access where traditional channels are weak, but the holder is accepting a different bundle of risks."

Platform payouts and programmable flows

Some of the most interesting future-facing use cases for USD1 stablecoins involve payouts and automated payment logic. Programmability, meaning payment rules that can be triggered or enforced by software, is one reason digital tokens attract so much attention. A platform might want to split revenue among creators, route affiliate payouts instantly, hold funds in escrow, meaning temporary holding until conditions are met, or release payments when a service milestone is completed. These ideas are appealing because they combine a dollar-linked unit with software-driven settlement.^[1]^[2]

This use case is real, but it is less mature than the earlier ones. The IMF says future demand could arise from new use cases supported by enabling legal and regulatory frameworks. The BIS also notes novel programmability functions as one reason stablecoins continue to attract demand despite important limitations. That is a careful way of saying the technical possibilities are clear even if the institutional foundations are still uneven.^[1]^[2]

Where might this work best? Usually in closed or partly closed digital environments where participants already accept digital payout methods and where the platform can manage compliance, customer identification, and operational recovery. A global freelance platform, gaming marketplace, or creator network may find USD1 stablecoins attractive because payouts can be frequent, small, and international. The platform can automate part of the process, reduce banking friction in some countries, and give recipients access to dollar-linked balances.

But automated money is not automatically better money. Once the flow reaches the edge of the system, the same old issues return. Can the recipient actually use the funds? Is there a lawful and affordable way to redeem or spend them? Who handles mistakes, scams, or disputes? Does the platform create tax records? Does it comply with anti-money laundering and countering the financing of terrorism rules, often shortened to AML and CFT, meaning rules meant to stop criminal abuse of the financial system? FATF's work is directly relevant here because it shows that implementation of virtual-asset standards is still uneven across jurisdictions and that financial-integrity risks remain significant.^[6]

For that reason, programmable payouts are better understood as an emerging use case than a finished one. The value is highest when software coordination is hard for older payment systems to match, but the risk is highest when legal obligations, consumer expectations, and cross-border compliance have been treated as an afterthought.

Where USD1 stablecoins may not fit well

A useful guide should spend time on non-use cases, because that is where hype usually goes unchecked. USD1 stablecoins may not be the best fit for ordinary domestic payments where a local faster-payment system is already cheap, fast, and well understood. They may also be a poor fit for low-value retail purchases on networks with variable fees, for users who are likely to lose access credentials, or for businesses that rely heavily on card-style dispute handling. In such contexts, the old system may simply be better.^[2]^[4]^[9]

USD1 stablecoins can also be a weak fit where regulatory treatment is unclear or unstable. A payment method can be technically elegant and still be operationally unusable if reporting, tax, accounting, consumer disclosures, or licensing questions remain unresolved. The FSB, FATF, BIS, and Federal Reserve sources all point in the same direction here: regulation is not a side issue. It is part of the product. If the law is uncertain, the use case is uncertain too.^[2]^[4]^[5]^[6]

Another weak fit is any situation that assumes perfect self-custody from ordinary users. Self-custody means the user, rather than a bank or platform, controls the secret credential that authorizes transfers. Some users can handle that. Many cannot, especially at scale. Lost credentials, phishing, meaning fraudulent messages or websites that trick users into revealing access data, device compromise, and irreversible mistakes remain serious barriers to mainstream use. A system may work beautifully for a technically confident operator and very poorly for a stressed first-time user. That gap matters. Good payment design is not only about what is possible. It is about what is survivable for normal people.^[2]^[6]

Finally, USD1 stablecoins may be a poor fit if the whole proposition depends on saying "trust us" while offering limited reserve disclosure, ambiguous redemption language, or thin governance. In that case, the project is not really selling a payment innovation. It is selling opacity. The stronger the use case, the less it needs that kind of faith.

What separates a strong design from a weak one

Two stablecoin setups can appear identical from the wallet screen and be radically different once you look underneath. That is why a serious discussion of USD1 stablecoins should focus on design quality as much as on use-case narratives.^[5]^[9]

The first separator is redeemability, meaning whether the holder can exchange the asset for U.S. dollars at face value in a timely and legally clear way. The BIS and ECB both stress that reserve-backed stablecoins derive credibility from reserve assets and the capacity to meet redemptions. A stablecoin that is easy to buy but hard to redeem is functionally weaker than one that supports both directions with clear terms.^[2]^[8]

The second separator is reserve quality and transparency. Reserve assets should be understandable, liquid, and visible enough that the market can judge whether the arrangement can withstand stress. If the reserve pool reaches for yield, meaning it takes extra risk in search of higher returns, the holder needs to ask who is really earning that return and who bears the downside if redemptions surge. The BIS annual report points to the tension between a profitable stablecoin business model and the promise of always maintaining stability under stress. That tension is not academic. It goes to the heart of whether the use case remains reliable when conditions worsen.^[2]

The third separator is governance, meaning who makes decisions, who can freeze or block transfers, who manages incidents, and who is accountable when something fails. The FSB and CPMI-IOSCO work both emphasize governance and risk management because payment arrangements become socially important once enough people rely on them. Informal governance can work during calm periods and then look dangerously thin during a crisis.^[5]^[9]

The fourth separator is compliance coverage. FATF's 2024 targeted update found that 75 percent of reviewed jurisdictions were still only partially compliant or non-compliant with the relevant standards for virtual assets and virtual-asset service providers. That does not mean every use of USD1 stablecoins is suspicious. It means the global compliance landscape is incomplete. Any use case that depends on clean cross-border operation has to be judged against that reality.^[6]

The fifth separator is user protection and recoverability. Recoverability means the ability to fix errors, restore access, or compensate losses when something goes wrong. Payment systems earn trust not only by moving money when things go right, but by containing damage when things go wrong. This is one reason why comparisons with cards, banks, and regulated payment institutions are still relevant. Legacy systems are often criticized for being slow or expensive, but they also include a thicker layer of recourse, meaning practical ways to seek correction or compensation.

A strong USD1 stablecoins design, then, is not just fast. It is redeemable, transparent, well governed, legally supportable, operationally resilient, and usable by the intended audience. If one of those pillars is missing, the use case may still exist, but it is weaker than it looks.^[2]^[5]^[9]

Frequently asked questions

Are USD1 stablecoins mainly for crypto trading or for everyday payments?

Today, the strongest evidence still points to use within digital-asset markets as the most established function, especially as a bridge, settlement unit, and collateral asset. That does not rule out broader payment use, but the broader use cases are more sensitive to regulation, redemption quality, and local payment alternatives.^[1]^[2]^[8]

Can USD1 stablecoins lower remittance costs?

Sometimes yes, but not automatically. The middle leg of the transfer can be very efficient, yet the total cost still depends on buying, sending, redeeming, and possibly converting into local currency. The World Bank's remittance data show why alternatives are worth exploring, but the BIS warns that end-to-end design and regulation still determine whether the benefit is real.^[3]^[7]

Are USD1 stablecoins the same as a bank deposit?

No. Even when USD1 stablecoins are designed to track one U.S. dollar closely, the holder's rights, protections, and risk exposures can differ materially from those of a bank depositor. The reserve structure, issuer obligations, custody model, and legal regime all matter.^[2]^[4]^[5]

Why do policymakers worry about a dollar-linked stablecoin if users find it helpful?

Because a tool can help individual users and still create system-level side effects. The IMF, BIS, and ECB all note the possibility of currency substitution, capital-flow volatility, and broader spillovers if U.S. dollar stablecoins become deeply embedded in economies that rely on other currencies.^[1]^[2]^[8]

What is the clearest sign that a USD1 stablecoins use case is real?

The clearest sign is not hype, trading volume, or social media buzz. It is repeatable economic value after full costs and risks are counted. If users keep choosing USD1 stablecoins because transfers settle when banks are closed, because remittance costs fall on a specific corridor, or because treasury movement becomes materially simpler, that is a real use case. If interest fades once promotional subsidies disappear, the use case was probably weak.

Do rules and compliance reduce the usefulness of USD1 stablecoins?

They can add friction, but they also determine whether a use case can scale safely. The most durable payment systems are not the ones that avoid rules; they are the ones that can operate efficiently while meeting them. FATF, FSB, BIS, and Federal Reserve work all support that view.^[2]^[4]^[5]^[6]

Closing perspective

The most balanced way to understand USD1 stablecoins is to see them as a tool, not a destiny. They are neither a magical replacement for the financial system nor a meaningless sideshow. The strongest current use case remains settlement and liquidity inside digital-asset markets. The strongest broader real-economy candidates are cross-border transfers, selected merchant settlement flows, business treasury movement, and dollar access where traditional channels are weak. Future applications in automated payouts and software-driven commerce are plausible, but they depend on stronger legal, operational, and compliance foundations than many public narratives admit.^[1]^[2]^[3]^[5]^[6]

For readers arriving at USD1usecase.com, that is probably the most useful takeaway. A good use case for USD1 stablecoins is specific, measurable, and honest about trade-offs. It saves time or money for a defined user, under a clear legal and operational setup, without pretending that speed alone solves trust. When those conditions are met, USD1 stablecoins can be genuinely useful. When they are not, older payment tools may remain the better answer.
