- A Fianto payment link is one https address per price: checkout.fianto.xyz/l/ followed by a 16-character code you cannot choose.
- Paste it as a button or text link. Do not put it in an embed or iframe block: the checkout sends X-Frame-Options: DENY, so browsers refuse to show it inside another page.
- The merchant pays nothing. The customer pays the price plus, on a subscription, a flat 0.01 USDC network fee with each charge today, and no Fianto fee during the beta.
What exactly is a Fianto payment link?
A Fianto payment link is a reusable https address for one price of one product, made in the dashboard under Payments, then Payment links. It looks like https://checkout. followed by 16 random letters and digits. The code is fixed for the life of the link, you cannot pick it, and there is no custom domain or QR code. How to create one, with its email and limit options, is covered in USDC payment links: how to create and share one.
Four facts decide how you place it on a site builder:
- It is a link, nothing more. Fianto has no WordPress plugin, no Webflow or Framer component and no embeddable widget for payment links. Any element that can hold a URL can hold it.
- It cannot be framed. Fianto's checkout answers every request with
X-Frame-Options: DENY(checked on 15 October 2026), so an Embed, HTML or iframe block shows an empty box. Use a button. - It sells exactly one price. A pricing table with three plans needs three links, one under each plan. A one-time price opens a payment checkout, a monthly or yearly price opens a subscription checkout.
- It is reusable. Many people can click the same button; each click opens a new checkout session that stays open for 30 minutes.
When someone shares the address in a chat app or a Notion bookmark, the preview reads "<product>, <merchant>" with the line "Pay from any Solana wallet." The page asks search engines not to index it, so the link will not compete with your own pages in search.
How do you add a USDC payment link to WordPress?
In WordPress you add a Fianto payment link with the core Buttons block, and no plugin is needed. For a WooCommerce store, see WooCommerce and USDC. The steps below follow WordPress's own Buttons block documentation, last modified on 1 September 2026:
- Open the page in the block editor, click the + Block Inserter and choose Buttons, or type /buttons in an empty paragraph and press Enter.
- Type the button text, for example "Pay 49 USDC" or "Subscribe with USDC".
- Select the button, click Link in its toolbar and paste the payment link. WordPress's documentation says the link can also be set to open in a new tab.
- Publish, then click the button on the live page to check it opens your product card.
The same works in the classic editor or a widget: any text link to the address is enough. A WooCommerce store is a different case, since a payment link cannot read a cart total. It sells one fixed price.
How do you add a payment link button in Webflow or Framer?
Both Webflow and Framer take a Fianto payment link in an element's link setting, as an external URL. Neither needs custom code.
Webflow
Select the Button or Link Block, open its link settings, choose the URL option and paste the payment link. Webflow's Designer API reference for link settings lists url among the link modes, next to page, page section, email, phone and attachment, plus an option to open the link in a new tab. Publish, then click the button on the live site, not in the Designer.
Framer
Select the button or text, click the + next to Link in the right-hand properties panel and paste the address into the Link To field. Framer's help article on email and phone links describes that same Link field, and warns that those links may not work in preview mode. Test your payment button on the published site too.
How do you add a USDC payment link to a Carrd site?
In Carrd you paste the payment link into the URL field of a Buttons element, or of any other element Carrd lets you link. Carrd's URL types documentation says an external site can be opened "optionally with one or more flags". To open the checkout in a separate tab, add the blank flag after two vertical bars:
https://checkout.
Carrd fits a one-page offer well: one section, one button, one link. If you sell two plans, give each its own button and its own link, and say in the button text which one it is, because the link page shows only that one price.
How do you sell from a Notion page with a payment link?
In Notion you sell with a payment link by turning text into a link or by pasting the link as a bookmark. Notion has no payment block, and Fianto adds none.
- Text link: select words such as "Buy the guide for 25 USDC" and press Cmd or Ctrl + K, then paste the address. Notion's keyboard shortcuts page lists that shortcut for adding a link.
- Bookmark: paste the address on an empty line and pick "Paste as bookmark". Notion's embeds and bookmarks help says a bookmark shows the page title, description and URL. For an open link those come from the page's own tags: "<product>, <merchant>" and "Pay from any Solana wallet."
Which payment link goes on which button?
One button needs one link, and the link decides the price, the charge and what happens after payment. The table shows what each kind does once the customer clicks.
| One-time price link | Monthly or yearly price link | |
|---|---|---|
| Button on the card | Pay with a wallet | Approve with a wallet |
| What the customer signs | One payment | One approval, then renewals every 30 or 365 days without a new signature |
| Fees on top of your price | None but the Solana transaction fee, under $0.01 | 0.01 USDC with each charge today, plus SOL account rent the checkout shows |
| After payment | A Continue button to your https after-payment address, if you set one | No redirect; the receipt points to the customer portal |
| Your cost | Nothing | Nothing |
The link page shows your price only; the checkout adds the customer's fees and shows the total before anything is signed. There is no Fianto fee during the beta, and after it the customer pays about 0.1 to 0.5% on top while you still pay nothing. A monthly link is the subject of selling a monthly USDC plan from one URL, and a one-client project link in getting paid in USDC as a freelancer.
Create a payment link in the dashboard and paste it into your site builder. No Fianto fee during the beta.
How accepting USDC worksHow do you check the button works and see the sales?
Test a payment link button by opening the published page in a private window and clicking it: you should land on a card with your name, the product, the price in USDC and the wallet button. There is no test mode, so a real test payment moves real USDC; a 0.01 USDC price is the smallest you can make.
- A link only takes payments while it is Open. A closed, ended or full link, or one whose price was ended, shows a closed screen instead, so check the link's status in the dashboard before you blame the builder.
- Your account must be approved before a link can be paid.
- Sales appear under Payments and on the link's own page in the dashboard. If you have code, each link payment also reaches the webhook endpoint of your hidden "Shop" application, tagged with
metadata.; the payment link sales docs show the fields.source = "payment_ link" - Link payers get no email from Fianto. If you need to deliver something, put it behind your after-payment address, or ask for an email on the link and send it yourself.
If you would rather have a button that creates a checkout for each order from your own server, with your order id attached, that is the coded route in adding a "Pay with USDC" button to your website.
