To accept stablecoin payments you need a receiving method, an off-ramp to local currency, and a settlement account. The full flow, costs, and options.
To accept stablecoin payments, a merchant needs three things: a receiving method (a wallet address or a payments API that generates one), an off-ramp that converts USDC or USDT into local currency when you need fiat, and a settlement destination, usually your business bank account. The customer sends dollar-pegged tokens, the transfer settles on-chain in seconds, and the funds land in your account in minutes over a local rail. No card network in the middle, no chargebacks, and no two to three day wait.
That's the short answer. The rest of this guide covers each step, the three ways to set it up, what it costs, and what a real merchant flow looks like.
A stablecoin is a digital token pegged to a currency, almost always the US dollar. One USDC is designed to be worth one dollar, backed by cash and short-term Treasuries held by the issuer. The two that matter for merchants are USDC (issued by Circle) and USDT (issued by Tether).
A stablecoin payment is a transfer of those tokens from the customer's wallet to yours, recorded on a public blockchain like Polygon, Base, Tron, or Stellar. A few terms you'll see:
Nothing about this requires the merchant to hold crypto as an investment. Stablecoins here are a payment rail, the same way ACH or Pix is a payment rail.
Here is the full path, step by step:
Steps 1 through 5 are about receiving. Steps 6 and 7 are about getting paid in something you can spend on payroll and rent. Most of the complexity, and most of the compliance work, lives in 6 and 7.
| Payments API or orchestration provider (like BlindPay) | Self-custody wallet | Card network with crypto rails | |
|---|---|---|---|
| How it works | A provider handles receiving, conversion, and payout to your bank through one API | You publish your own wallet address and manage the keys | The customer pays in crypto, the network settles to you in fiat like a card sale |
| Speed to your bank | Minutes over local rails like Pix, SPEI, or RTP | Depends on the exchange you use to cash out, often one to three days | Card-style settlement, typically one to three business days |
| Cost | Network fee plus an itemized FX spread and payout fee | Gas fees plus exchange fees and withdrawal fees | Card-style processing fees, often similar to regular card pricing |
| Compliance burden | Provider runs KYC, KYB, and transaction screening | All on you: sanctions screening, record keeping, tax lots | Network and acquirer handle it |
| Technical lift | One integration, webhooks for status | Low to start, high to reconcile at volume | Low, usually a checkout plugin |
| Best for | Businesses that want fiat in local accounts, across many countries | Very low volume, crypto-native teams | Merchants who want no change to their card workflow |
What's interesting here is that the first column is the only one that gets you both the speed of stablecoins and money in a local bank account. The self-custody route is fast on-chain and slow off-chain. The card route keeps the card-era settlement timeline.
BlindPay sits in the first column, on the settlement side. It's not a card acquirer and not a checkout button. It's the layer that turns stablecoin balances into local currency and gets money into the right bank account, in 100+ countries and 80+ currencies, through one API.
In practice that looks like:
We wrote more about why the blockchain part should stay invisible to merchants in Stablecoin for the Ordinary.
Start with USDC and USDT. Between them they cover the vast majority of stablecoin payment volume.
The network matters as much as the token. Accept on low-fee chains (Polygon, Base, Arbitrum, Stellar, Tron) so customers aren't paying a few dollars in gas on a $30 order. Tell customers exactly which network to use. A USDC transfer sent on the wrong chain is the most common support ticket in stablecoin acceptance.
A card payment typically costs the merchant 1.5 to 3.5 percent, plus another 1 to 2 percent on international cards, plus a currency conversion spread if the customer pays in another currency. Then there's the chargeback exposure.
A stablecoin payment breaks down differently:
The honest comparison depends on your corridor and volume. A merchant receiving USDC and paying out BRL over Pix will see a very different number than one receiving USDT and paying out EUR over SEPA. Ask for an itemized quote on your real amount before comparing anything. BlindPay splits the spread and the payout fee into separate numbers so you can see which one moved. Plan pricing is on the pricing page.
Take a US marketplace with 2,000 sellers in Brazil and Mexico. Buyers pay by card. Sellers get paid out weekly.
Before: the marketplace sends international wires. Each one costs $25 to $50, takes two to five business days, and arrives short after intermediary bank deductions. Small sellers wait a week for $80 payouts that lose $30 on the way. Support spends Mondays answering "where is my money."
After: the marketplace holds its payout float in USDC. Every Friday it requests a quote per seller and executes. BlindPay converts USDC to BRL and MXN at locked rates and pays out over Pix and SPEI. Sellers see funds in minutes, at the amount they were quoted. The marketplace reconciles through webhooks instead of bank statements.
Same buyers, same checkout. The only change is the settlement rail, and it's the part sellers actually feel.
A short checklist:
For the leadership view on how stablecoins, local rails, and virtual accounts combine, read Orchestrating Local Payments and Stablecoins. For the API itself, start with the BlindPay docs.
The receiving part is easy. Getting paid in local currency, in minutes, compliantly, in every market you sell into is the part worth solving properly. If you want to see a live quote for your corridor, talk to the BlindPay team.
