Understanding the different payment streams on Render Network
If you have insufficient funds to process a job, you will have to add tokens to your account in order to submit the job. Additionally, if you run out of RNDR in your account while your job is in progress, your job will be paused until you add more tokens to your account.
RNDR Credits and RNDR Tokens can be added in the Render Network Portal by following the following steps:
In the left hand menu, click "Add RNDR"
A window will appear prompting you to deposit funds (see below).
Select the "Add RNDR Credits" tab or "Add RNDR Tokens" tab
Enter how many Credits or Tokens you would like to purchase or load, then continue.
This portal can also be reached by clicking on your balance directly
Hitting "Continue to Checkout" will redirect to the selected payment provider
Hitting "Deposit RNDR" will open Metamask
You can add RNDR tokens to your account using Metamask - please see a guide for this here.
