- A Fianto price is 0.01 to 1,000,000 USDC with up to 6 decimals, fixed once created. You receive exactly that price; the merchant pays no fee of any kind.
- Round your price, not the customer's total: the total carries the fees, and those change when the beta ends.
- Matching your card price is the simple default. A discount for paying in USDC loses money against cards once it is larger than the card fee you would have paid.
What can a USDC price be on Fianto?
A USDC price on Fianto is an amount from 0.01 to 1,000,000 USDC, with at most 6 decimals, charged once, every 30 days or every 365 days. USDC is a stablecoin issued by Circle, and Circle's USDC page says, as read on 15 October 2026: "USDC is a digital dollar backed 100% by highly liquid cash and cash-equivalent assets and is redeemable 1:1 for US dollars." That is why a USDC price reads like a dollar price, and why the dashboard shows your amounts as US dollars, counted at 1 USDC = 1 USD.
| Rule | Limit |
|---|---|
| Amount | 0.01 to 1,000,000 USDC |
| Precision | Up to 6 decimals, the smallest USDC unit |
| Billing | One time, monthly (every 30 days) or yearly (every 365 days) |
| Changing a price | Not possible: add a new price and end the old one |
| Prices per product | 20 active at once |
| Products | Up to 1,000 |
Six decimals are allowed, but use two. The dashboard shows amounts as dollars rounded to the cent, so a price of 9.995 would show there as $10.00 and make your own records harder to match. The fixed-price rule is the one that shapes everything else: a price is set once, so pick the number with care and treat a later change as a new price. Products and prices in the docs covers creating them.
Should your USDC price match your card price?
Match it, unless you have a reason not to and have done the sum below. Different prices for the same product by payment method confuse buyers and your own bookkeeping, and the saving you can pass on is smaller than it looks.
The sum: as of 15 October 2026, Stripe's pricing page lists 2.9% + 30 cents per successful domestic US card charge, with 1.5% more for international cards and 1% more if currency conversion is required. On Fianto the merchant pays nothing per payment. So on a 20.00 sale, the most a USDC discount can give away before you earn less than on a domestic card is the card fee itself:
| Price | Domestic card fee you avoid | USDC discount that breaks even | 5% off in USDC |
|---|---|---|---|
| 9.00 | 0.56 | 6.2% | 0.45, under the card fee |
| 20.00 | 0.88 | 4.4% | 1.00, over the card fee |
| 190.00 | 5.81 | 3.06% | 9.50, over the card fee |
The pattern: a percentage discount for USDC costs less than the card fee on small prices, where the card's fixed 30 cents weighs most, and more than it on large ones. If you want to reward USDC payers, a coupon with a limit is easier to stop than a second price list; coupon recipes for USDC plans has set-ups for that. The full card comparison lives in USDC vs card fees.
What does the customer pay on top of your price?
The customer pays your price plus every fee, and you receive the price untouched. The hosted checkout lists each part before anyone signs: a "Fianto fee" row (0.00 during the beta), a "Network fee" row on subscriptions, a "Solana network fee" row that reads "paid by you, under $0.01", and the "Total". The Solana network fee is paid in SOL from the customer's wallet, apart from the USDC total.
| Your price | Customer pays in USDC today | After the beta, if the rate were 0.5% | You receive |
|---|---|---|---|
| 9.00, one-off | 9.00 | 9.045 | 9.00 |
| 19.00, monthly | 19.01 per charge | 19.105 per charge | 19.00 per charge |
| 190.00, yearly | 190.01 per charge | 190.96 per charge | 190.00 per charge |
The subscription rows carry the flat network fee with every charge, 0.01 USDC today on plans created since 6 October 2026; one-off payments carry none. The post-beta column is an illustration at the top of the owner's stated range of about 0.1 to 0.5%, worked out on your price and rounded down to the smallest USDC unit, so any rounding favours the customer. A subscriber also pays account rent in SOL when subscribing, which the checkout shows at its live amount.
See the hosted checkout that shows your price and every fee before the customer signs.
See the checkoutShould you round the price or the total?
Round the price. You might be tempted to price a plan at 18.99 so that the subscription total is exactly 19.00 today, with the network fee added. It works until the beta ends: once a Fianto fee is added, that total turns odd again, and the price you chose to make it round no longer reads as a deliberate price point.
Round prices also survive every place the price is shown. A payment link card and a shop listing show your price in USDC, and the fees are added on the checkout page; the checkout also shows the most you can charge per period, "Most [merchant name] can charge", which for a subscription is the price plus its fees. Your price is the one number the customer sees everywhere, so make it the clean one, and say "plus network fees" next to it on your own pricing page.
How low or high can a USDC price usefully go?
Very small subscription prices are allowed, but the fixed costs weigh more on them. A 0.50 USDC monthly plan is legal on Fianto, and the 0.01 USDC network fee charged with it today adds 2% for the customer, before the SOL they spend to subscribe. For prices under a few dollars, one-off payments make more sense: they carry no USDC network fee and no account rent. Nothing can cost less than 0.01 USDC, so per-request API pricing below a cent needs another tool, compared in x402 vs subscriptions for APIs.
At the other end, a single price can reach 1,000,000 USDC. Large one-off amounts are where USDC compares best with cards, but they raise the stakes of a mistake: payments on Solana cannot be pulled back by the customer, and there is no refund button. A refund is USDC you send back from your own wallet.
If your customers think in euros or pounds, you still price in USDC, a dollar token. Convert once, round, and accept that your local-currency revenue moves with the exchange rate; international payments without card FX fees shows where the conversion goes instead. Fianto has no other currency and no fiat payout. Why USDC rather than SOL is the right unit at all is argued in why price subscriptions in USDC, not SOL.
How do you set a price ladder you can change later?
- Put the prices people compare under one product: up to 20 can be active, for example a monthly price, a yearly price and a one-off lifetime price.
- Set the yearly price from the 30-day maths, not from twelve months of the calendar: monthly or yearly USDC pricing works it through.
- Use coupons for temporary cuts, so the list price stays put and the discount ends on its own.
- For a permanent change, add a new price and end the old one. Existing subscribers stay on the old price until you end it, and ending it cancels them at the end of their paid period; how to change a stablecoin subscription price covers both paths.
The merchant pays nothing on any of these prices: no Fianto fee and no network fee, during the beta or after it. The pricing page lists what Fianto charges today.
