Key Points

  • The 2025 GENIUS Act made stablecoin issuers safer, but card rails like Visa and Mastercard stay the primary way high-risk merchants get paid through 2028.
  • According to Venable LLP's March 2026 advisory, stablecoin transactions can settle within minutes, compared with one to three business days for card payments.
  • Spark reports US merchants paid a record $198.25 billion in card processing fees in 2025, a total that has tripled since 2009.
Three things high-risk merchants believe about stablecoins. Myth or fact?
Call each one, then see how other readers called it.
1 Accepting stablecoins makes a high-risk business look low-risk to underwriters.
2 Every stablecoin sale needs its own dollar valuation for tax purposes.
3 Card processing costs the same percentage for every merchant.

Card rails still take the order; stablecoins are arriving as a settlement layer behind them.

Quick Answer

No. Visa and Mastercard stay primary for high-risk merchants through 2028. After the GENIUS Act, stablecoin settlement, which refers to receiving dollar-pegged tokens, grows as a treasury layer, because underwriters price business shape.

Did this answer your question?

The stablecoin debate usually stops at fees. According to FinchTrade, credit card interchange ran 1.5% to 3.5% of each transaction plus a flat fee as of March 2025, and stablecoins promise to undercut that. Cheaper is not the same as safer.

Our underwriting team prices prepaid credit, delayed fulfillment, and stored balances, whatever rail the buyer uses. So below, I test what the GENIUS Act changed at your checkout, run the real cost math, and lay out the dual-rail plan I'd use: a dedicated card merchant account first, stablecoin settlement second. Then I put dates on it.

Here is my forecast, dated September 2026: through 2028, card rails stay the primary way high-risk merchants get paid, even after the 2025 GENIUS Act. Stablecoins win a narrower job. They become a settlement and treasury layer, not the front door.

According to Venable LLP's March 2026 advisory, stablecoins are now "an emerging consideration" for merchants. Emerging is the right word. Our underwriting team's view is that a processor prices the shape of a business, such as prepaid credit, delayed fulfillment, and stored balances, rather than its product label. A new payment rail does not change that shape.

What did the GENIUS Act actually change for high-risk merchants?

In our underwriting view, processors price a merchant's business shape, not its payment rail. The GENIUS Act made stablecoin issuers safer; it did not change that shape.

An analysis of 16 sources shows the same split. I use a simple issuer-versus-checkout test: ask what a new rule changes for the coin, then ask what it changes at your checkout.

  • For the issuer: once the law's requirements take effect, US merchants must accept only coins from a "permitted stablecoin issuer."
  • For settlement: according to Venable LLP's March 2026 merchant advisory, stablecoin transactions can settle within minutes, compared with one to three business days for card payments.
  • For your books: the Internal Revenue Service treats stablecoins as property, so each sale needs a dollar value and each conversion to fiat needs gain or loss accounting.

CNBC described the signing as the moment stablecoins "made it big in the U.S." A common misconception is that the law created checkout demand. The reality is different. Venable found consumer demand "remains low at this time and uneven across customer segments, industries, and geographies."

In practice, the law legitimized a settlement asset. It did not rewrite underwriting. In our experience, underwriters still price prepaid credit, delayed fulfillment, and stored balances, whichever rail the buyer uses. So the documentation high-risk underwriters need, what a high-risk merchant account costs, and how reserves on held funds work all still follow the business, not the coin.

What 12-24 months May Bring

Where stablecoin and card rails split high-risk volume

Dated forecasts on how US high-risk merchants will divide payments between card rails and GENIUS Act-era stablecoin settlement through 2028.

How high-risk payment rails shift by 2028

Read each forecast as a dated call on fees, settlement speed, disputes or regulation, and weigh it against the evidence that would overturn it.

87/100
High confidence 12-24 months

High-risk merchants that add stablecoins will still handle disputes. Over the next 12-24 months, they will build or buy refund workflows for irreversible stablecoin payments. Buyers of future deliverables and recurring billing will keep paying by card for its chargeback and consumer protection.

86/100
High confidence 12-24 months

With the GENIUS Act signed into law and requiring 1:1 reserve backing, US processors will treat regulated dollar stablecoins as an acceptable settlement asset. Most high-risk merchants, however, will receive them through conversion services that pay out in fiat, because holding stablecoins brings property-style tax accounting on every transaction.

The Contrarian Call
75/100
Medium confidence 12-24 months

Over the next 12-24 months, a growing share of consumer stablecoin spending will run over Visa and Mastercard, through stablecoin-funded cards and network-built blockchain products. As a result, stablecoin growth will reinforce card acceptance at merchants rather than bypass it.

74/100
Medium confidence 12-24 months

Over the next 12-24 months, more US high-risk merchants will offer stablecoin payment as a discounted option beside cards. They will price the stablecoin lane below card checkout to pass on part of the fee gap, as card processing costs build on 2025's record $198.25 billion.

73/100
Medium confidence 12-24 months

Through 2028, payment providers will converge on offering both rails from a single relationship. Stablecoin-first services will add card acceptance through bank partners, and processors serving high-risk merchants will add crypto partners. Neither rail will displace the other.

Weak Signals Worth Watching Merchants paid a record $198.25 billion in card processing fees in 2025, a figure that has tripled since 2009. Small merchants say card fees of 3 to 4% can consume about half of a 5% to 10% margin. Proposals already circulate to price stablecoin sales 1.4% to 2.8% below card sales. Venable notes that stablecoin transactions can settle within minutes, versus one to three business days for card payments. Practitioners working with high-risk merchants list rolling reserves and onboarding delays alongside chargebacks as core card-rail pain points. One stablecoin payments founder is weighing a bank partnership to add card acceptance. An operator working with high-risk merchants is integrating crypto partners. Crossmint already gives agents a choice between stablecoin wallets and Visa or Mastercard access. Venable warns that because stablecoin settlement is irreversible, merchants must design their own refund workflows. Card disputes cost $15 per dispute at a major gateway, and high-risk businesses are defined partly by being more chargeback-prone than traditional acquiring. The IRS treats stablecoins as property, so merchants must value each transaction in dollars and book gains or losses on conversion. Crypto-to-fiat platforms already pay merchants in fiat the next day and pass the conversion cost to customers. Crypto-funded card spend reached roughly $18 billion annualized in 2025, growing more than 100% while peer-to-peer crypto payments stayed flat. In June 2026, Mastercard announced a blockchain-based agent pay product for machines.

What would tilt high-risk volume off cards

Shifts in consumer behavior, card pricing and stablecoin regulation that would push high-risk merchants toward, or away from, full stablecoin settlement.

Our Margin for Error

We hold 87 with the most confidence, while 75 is the one we would flag as most likely to shift.

  • Stablecoin settlement becomes the high-risk liquidity lane. Expect that call to give way first should buyers or regulators reverse course.
  • Card networks absorb stablecoin spending. Stronger contrary evidence in the sources would make that the sturdier forecast.
Methodology Each forecast is scored 0-100 from the public sources shown for it: how many there are and how authoritative they are.

Are stablecoins really cheaper than a high-risk card merchant account?

On the headline fee, yes. Once refunds, conversion, and compliance are counted, the gap narrows, and the risk our underwriters price does not disappear with the rail.

The fee pressure is real. In a CNBC report, one voice put it bluntly: credit card fees "can be like 3 to 4%," which for a business running a "5%, 10% profit margin" is about "half of their earnings." Interchange also scales with risk. Its percentage portion usually runs between 1% and 3%, depending on the issuing bank, the network, and the merchant risk profile.

So why don't I tell high-risk merchants to switch? I run every option through a total-cost test:

  • Reversibility: according to Venable, stablecoin transactions are "generally irreversible once they are settled," so merchants must build their own refund workflows and decide refund currency, timing, and valuation.
  • Hidden offsets: Venable warns the savings "may be partially offset by custody arrangements, compliance tooling, and processor markups."
  • Conversion: stablecoin flows need on and off ramps plus separate compliance workflows.

Contrary to popular belief, a cheaper rail does not change what underwriters price. In our experience, that is prepaid credit, delayed fulfillment, and stored balances. A preorder or subscription buyer still expects a refund when something goes wrong.

The takeaway: stablecoins cut the fee, not the risk. In practice, dispute costs turn into refund staffing costs.

What is the best way for high-risk online businesses to take payments through 2028?

Keep a dedicated high-risk credit card merchant account as your primary checkout, then add stablecoin settlement as a layer. In our underwriting view, processor fit matters more than the rail.

Venable expects that for many merchants, stablecoin acceptance "may initially function as a niche or experimental offering rather than a primary payment method." Its authors add that adoption "will likely remain modest" until processors, gateways, and acquirers support stablecoins "alongside traditional payment methods."

Meanwhile, the card networks are moving in, not out. Venable reports networks are "upping their stablecoin integrations and offerings." In CNBC's coverage, the Visa side explained: "We have leaned in because we said, okay, it actually does help with some use cases."

A common misconception is that adding stablecoins means leaving your processor. I'd recommend a three-step dual-rail plan instead:

  1. Protect the card account. In our experience, an application should describe your real business shape and how each risk is controlled.
  2. Pick a processor that already boards your shape. Ask whether it has underwritten businesses like yours before.
  3. Pilot stablecoins where they pay off. Venable points to lower transaction costs, faster settlement, and enhanced global reach.

What this means: stablecoins arrive as an add-on to a card relationship. They are not an exit from one.

Keep cards primary. Add stablecoins when they earn it.

What will matter most for high-risk payments in the next 12-24 months?

In my view, three things matter most: card fee pressure, settlement speed, and who handles conversion. None of them pushes high-risk merchants off card rails.

What most buyers miss: the win is measured in days of cash, not basis points. I would revise this forecast if stablecoin wallets reach checkout at scale, or if providers add dispute protections that buyers actually trust.

Finance team member reconciling settlement reports and a cash-flow timeline at a desk
For high-risk merchants, the stablecoin payoff shows up in days of cash and cleaner conversion, not in the headline rate.

My bet for 2028: stablecoins will settle more high-risk money, but cards will still take the order. When card fees can eat about half of a thin margin, and interchange climbs with your risk profile, the pull toward a cheaper rail is real. It still does not reprice the business. According to Venable, settled stablecoin payments are generally irreversible, so refund risk simply moves in-house.

Our underwriting team frames the real question as fit. Has this processor boarded your shape before? Start there, then let stablecoin settlement prove itself on your slowest cash cycle.

Frequently Asked Questions

Will stablecoins replace credit cards for high-risk merchants by 2028?

I don't expect them to. Card rails should stay the primary way high-risk merchants get paid through 2028. Stablecoin settlement, receiving funds as a dollar-pegged digital token, will grow beside cards as a treasury layer.

Why are card processing fees so high for high-risk businesses?

US merchants paid a record $198.25 billion in card processing fees in 2025, a total that has tripled since 2009. Interchange, the fee the card-issuing bank collects on each sale, combines a flat per-transaction charge with a percentage tied partly to your risk profile. That is why processor fit matters as much as the headline rate.

Did the GENIUS Act make stablecoins safe to accept?

It made issuers safer. It did not change what drives your approval: refund exposure, fulfillment timing, and dispute history. A regulated coin does not make a risky model less risky.

Can customers dispute a stablecoin payment?

Not the way they dispute a card charge. According to Venable, settled stablecoin payments are generally irreversible, so merchants must decide whether refunds go out in stablecoin or fiat. The dispute work moves to your own support team.

Should my business add stablecoin payments now?

I'd pilot them only after your card merchant account is stable. SeamlessChex works with established, operating businesses, and I'd start any stablecoin test where faster settlement clearly improves cash flow.

To qualify for a SeamlessChex account, a business needs an established operating history and $25,000+ in monthly processing volume.
