How payments, subscriptions and the on-chain program work.
These pages explain what happens underneath a fianto payment: the statuses a payment and a subscription move through, when fianto treats a payment as final, how the service fee works, and the Solana program behind subscriptions.
Payment lifecycle
How a checkout session, its order and each payment move between statuses, and which events each move sends.
Subscription lifecycle
How a subscription starts, renews, falls past due and ends.
Finality
Why the payer sees success at confirmed, but an order is paid only at finalized.
Fees
How fianto's service fee is set, computed, paid and shown.
The Subscriptions program
The Solana program behind fianto subscriptions, and what it checks on every charge.
