- The payer's wallet signs one transaction. The payer is the only signer.
- That transaction sends the price in USDC straight to the merchant's wallet.
- In the same transaction, the service fee goes to fianto's treasury — only when the service fee is above zero.
- fianto broadcasts the signed transaction and watches the chain. The price goes straight to the merchant's wallet and any service fee to fianto, in the same transaction. Nothing is held in between.
- Subscriptions work differently: fianto's charging key co-signs the subscribe transaction and signs each renewal, within the limits the on-chain program enforces.
Only USDC on Solana is accepted.
