SteadyEdge uses NOWPayments for crypto balance top-ups and for direct crypto subscription charges. The important part is understanding what gets credited, what stays pending, and what does not activate automatically.

What this is

This article explains how the NOWPayments flow works, what happens after you create a payment, and how invoice states relate to subscription activation.

When to use it

Use this article if:

you want to add funds to your internal balance
you want to pay for a plan through a crypto charge
you need to understand pending, paid, underpaid, or failed invoice states

Before you start

Keep these rules in mind:

you must send funds on the exact network shown in the payment flow
the product input accepts values from 0.01 to 10000 USD
the selected payment method can still have its own higher provider minimum
the UI shows the provider minimum for the chosen currency when available
some environments may not have NOWPayments configured at all

Step by step

Step 1: Open the top-up flow

Go to Dashboard -> Profile -> Billing and open Top Up.

If you try to subscribe from balance and funds are missing, the billing flow can also open the top-up modal with the required amount prefilled.

Step 2: Choose asset and network carefully

Inside the modal:

Search for the asset.
Select the correct network.
Enter the USD amount.
Create the payment.

The asset and network choice matters more than the coin brand alone. Wrong-network USDT is still the wrong payment.

Step 3: Use the generated payment details exactly

After the payment is created, the modal shows:

a QR code
the payment address
the exact crypto amount
the pay currency

Send the exact amount to the exact address on the exact network.

Step 4: Wait for confirmation

Creating a payment does not credit your balance immediately. Your balance changes only after NOWPayments confirms the payment and SteadyEdge processes the callback.

If NOWPayments is temporarily unavailable in your environment, the payment flow may fail before payment details are generated.

Step 5: Understand invoice behavior

Subscription charges create invoice records with statuses such as:

pending
paid
underpaid
failed

Important payment behavior:

paid top-ups credit available balance
paid subscription charges activate or renew the subscription
underpaid subscription invoices do not activate the subscription automatically

Step 6: Know the difference between top-up and direct plan charge

The current payment surfaces differ:

Top-up adds funds to available balance after confirmation
Direct subscription charge creates a subscription invoice
Subscribe from balance uses existing available balance and does not create a new crypto payment

What you should see

A healthy payment flow shows:

the correct selected asset and network
a generated address and QR code
a pending payment state first
a balance or invoice status change after confirmation

Common mistakes

sending funds on the wrong network
sending less than the exact requested amount
reusing an old payment instead of creating a fresh one when in doubt
expecting balance to update before confirmation is processed
confusing a balance top-up with a subscription invoice
