Features

Payment infrastructure built around direct settlement.

From invoice creation to on-chain confirmation, FlowNoc gives your application a structured payment lifecycle without taking custody of merchant funds.

Hosted checkout

Customers open a FlowNoc-hosted payment page. They choose an available network and token, then send funds to the merchant wallet shown on that page.

You can create the checkout from the dashboard or the API. Optional network lock skips the picker and opens the payment screen directly.

Payment verification

FlowNoc attributes an on-chain transfer only when destination, network, token and amount match the invoice, then waits for the required confirmations.

Paid

Underpaid

A valid payment arrived below the paid band. One transaction credit is consumed. The processing fee uses the verified received USD.

Overpaid

A valid payment arrived above the paid band. One transaction credit is consumed. Excess crypto still settles to your wallet.

Expired

The invoice window ended without a qualifying payment. No transaction credit is consumed.

Merchant wallets

You configure receiving addresses in FlowNoc. Customers pay those addresses. FlowNoc never holds the funds and never asks for a private key or seed phrase.
