faq:
  - q: "Are stablecoin payments cheaper than credit card processing?"
    a: "Usually, yes, especially for international sales. Card processing typically costs 1.5 to 3.5 percent per transaction, plus about 1 percent in cross-border fees and 1 to 3 percent in currency conversion on foreign cards, plus chargeback fees. A stablecoin payment costs a network fee of cents on low-cost chains, usually paid by the sender, plus a flat payout fee and a sub-percent FX spread if the merchant converts to local currency."
  - q: "What fees does a merchant pay to accept stablecoins?"
    a: "Three possible costs: the network or gas fee, which the sender usually pays and which is cents or less on Polygon, Base, Arbitrum, and Stellar; the FX spread when converting USDC or USDT into local currency; and a payout fee to deliver funds to a bank account over a local rail. Some providers also charge a platform subscription. BlindPay itemizes the spread and payout fee separately on every quote."
  - q: "Do stablecoin payments have chargeback fees?"
    a: "No. A confirmed stablecoin transfer is final, so there are no chargebacks, no chargeback fees, and no rolling reserves held against future disputes. Merchants still issue refunds when they choose to, by sending a new transfer back to the customer."
  - q: "What hidden costs do card payments have for merchants?"
    a: "Beyond the headline rate: cross-border assessments on foreign cards, currency conversion markups, chargeback fees typically between $15 and $100 per dispute, rolling reserves that hold back a share of revenue for months, PCI compliance costs, and the working capital cost of waiting one to three business days for every payout."
  - q: "When are card payments still the better choice?"
    a: "When your customers don't hold stablecoins and won't get them, when you need consumer credit at checkout, or when your sales are small, domestic, and low-risk. Many merchants keep cards for checkout and use stablecoins for the expensive part: cross-border settlement and payouts."

Card processing typically costs merchants **1.5% to 3.5% per transaction**, and international sales add roughly **1% in cross-border fees and 1% to 3% in currency conversion**, before chargebacks. A stablecoin payment costs a **network fee of cents** on low-cost chains (usually paid by the sender), plus a **flat payout fee and a sub-percent FX spread** if you convert to local currency. For cross-border merchants, the gap is often several percentage points of revenue.

The headline rates only tell half the story, though. Both rails have costs that don't show up on the pricing page. This guide puts all of them on the table.

## What does a merchant actually pay for a card transaction?

A card fee is three fees wearing a trench coat:

- **Interchange:** paid to the cardholder's issuing bank. The biggest piece, and it varies by card type, rewards tier, and whether the card was present.
- **Network assessment:** paid to the card network.
- **Processor or acquirer markup:** paid to whoever gave you the merchant account.

Blended, that lands at roughly 1.5% to 3.5% for most merchants. Then the international extras:

- **Cross-border fee:** around 1% when the card was issued in another country.
- **Currency conversion:** 1% to 3% when the customer pays in a currency different from yours.

And the ones nobody puts in a sales deck:

- **Chargeback fees:** typically $15 to $100 per dispute, win or lose, on top of the lost sale.
- **Rolling reserves:** higher-risk merchants often have 5% to 10% of revenue held back for months.
- **Payout delay:** one to three business days of float on every sale. At scale, that's real working capital.
- **PCI compliance:** audits, tooling, and scope reduction work.

## What does a merchant pay for a stablecoin transaction?

Fewer layers, so fewer fees:

- **Network fee (gas):** cents or less on Polygon, Base, Arbitrum, and Stellar. The sender usually pays it. Ethereum mainnet costs more, which is why payment flows mostly avoid it.
- **FX spread:** only if you convert USDC or USDT into local currency. The difference between the mid-market rate and your conversion rate.
- **Payout fee:** a flat or small fee to deliver funds to your bank over a local rail like Pix, SPEI, RTP, or SEPA.
- **Platform fee:** some providers charge a subscription. BlindPay's plans are on the [pricing page](/pricing).

No interchange, because there's no issuing bank. No network assessment, because there's no card network. No chargebacks, because confirmed transfers are final.

## Stablecoin vs card fees, side by side

| Cost | Stablecoin (USDC/USDT) | Credit card |
| --- | --- | --- |
| **Base processing** | Network fee of cents, usually paid by the sender | Typically 1.5% to 3.5% |
| **Cross-border** | None; the same transfer works in any country | Around 1% extra on foreign cards |
| **Currency conversion** | Sub-percent FX spread, only if you convert | 1% to 3% markup |
| **Payout to your bank** | Flat payout fee; minutes over instant local rails | Included, but 1 to 3 business days |
| **Chargebacks** | None; transfers are final | $15 to $100 per dispute, plus the lost sale |
| **Reserves** | None | 5% to 10% held for months on higher-risk accounts |
| **Weekend settlement** | Yes, 24/7 | No |

## A worked example: $100,000 a month in international sales

Take an online merchant selling $100,000 a month, mostly to customers outside its home country. These numbers are illustrative; your real rates depend on your processor, risk profile, and corridor.

**Cards:**

- Processing at 2.9%: $2,900
- Cross-border at 1%: $1,000
- Currency conversion at 1.5%: $1,500
- 20 chargebacks at $25 each: $500, plus the value of the disputed goods
- **Total: around $5,900 a month, or 5.9% of revenue,** before reserves and float

**Stablecoins, for the share of customers who pay that way:**

- Network fees: paid by the customer, cents each
- Conversion to local currency at a sub-percent spread, plus a flat payout fee per settlement
- No chargebacks, no reserves
- **Total: typically a fraction of the card cost,** and settled the same day

That's why cross-border merchants are the ones moving first. A domestic merchant on a good card rate saves less. A merchant selling across borders, paying 5% to 6% all-in, saves most of it. BlindPay's own figure for replacing correspondent banking with stablecoin settlement and local rails is up to 90% lower transfer costs.

## What are the hidden costs of stablecoin payments?

Being honest about the stablecoin side:

- **Customer adoption.** Not every customer holds USDC or USDT. Stablecoins work best as an added option, or for B2B invoices and marketplace payouts where the counterparty already uses them.
- **Refunds are manual.** No chargeback also means no automatic reversal. You send refunds yourself, so write the policy down.
- **Wrong-network transfers.** A customer who sends USDC on a network you don't support creates a support ticket and a recovery process. Be explicit at checkout.
- **Conversion spreads vary.** A provider quoting a low headline rate can make it back on the FX leg. Always ask for itemized quotes.
- **Accounting setup.** Your finance team needs a clear process for recording stablecoin receipts and conversions. It's not hard, but it's new.

None of these is a dealbreaker. All of them are cheaper than a 2% cross-border markup on every sale, forever.

## How do you compare quotes fairly?

The trap is comparing a blended card rate to a stablecoin headline rate. Hold these constant instead:

1. **Same amount.** Fees compress with size differently on each rail.
2. **Same day.** FX and spreads move daily.
3. **Same corridor.** USDC to BRL over Pix prices differently from USDT to EUR over SEPA.
4. **Itemized fees.** Spread, payout fee, and network fee as separate numbers.

BlindPay quotes split the FX spread from the payout fee, so you can see what the conversion costs and what the delivery costs, and which one moved if a rate changes. You can check a public corridor like [USDC to BRL](/usdc-to-brl) for today's rate.

## When should merchants keep cards?

When the customer doesn't hold stablecoins and won't. When the purchase depends on consumer credit. When sales are small, domestic, and low-risk on a great rate.

The pattern we see work: keep cards at checkout, and use stablecoins for the expensive part, cross-border settlement and payouts. Our guide to [how merchants accept stablecoin payments](/resources/more/how-merchants-accept-stablecoin-payments) covers the receiving setup, and [stablecoin settlement explained](/resources/more/stablecoin-settlement-for-merchants) covers how funds get to your bank.
