What is Fianto

A hosted checkout that lets an approved business take USDC on Solana, straight into its own wallet.

2 min read

Fianto is a hosted checkout for USDC on Solana. Your server creates a checkout session, the payer opens Fianto's checkout page, and signs a transaction that sends the money straight to your wallet.

What Fianto does

  • Hosted checkout. Fianto runs the payment page. Your server creates a session through the v1 API and sends the payer to it.
  • One-time payments and subscriptions. A session is either a single payment or a subscription that renews every 30 days or every 365 days.
  • Webhooks. Fianto tells your server when an order is paid, when a subscription renews and more.
  • A dashboard. You manage products and prices, see orders, payments and customers, and export them as CSV.
  • A payer portal. Payers sign in with their wallet to see and cancel their subscriptions.

What Fianto is not

  • Not a custodian. In a one-time payment the payer signs one transaction that sends the price in USDC to your wallet, and any service fee to Fianto, in the same transaction. Fianto broadcasts that transaction; nothing is held in between.
  • Not multi-currency. Fianto accepts only USDC.
  • Not usable before review. Every account is reviewed first. You create an account, fill in your business profile, turn on two-factor sign-in and prove your wallet. An admin then reviews it. Until your account is approved, dashboard data, applications and products are refused with merchant_not_approved, and your API keys answer 401 invalid_api_credentials, so no checkout can be created.
  • No test mode. There are no test keys and no sandbox. See Developers for how to test.
  • No refund API. To refund a payer, send the USDC back from your own wallet.

Money

The payer pays a service fee on top of your price, when the fee is above zero. It goes to Fianto's treasury in the same transaction. How money moves shows every transfer.
