Getting free MATIC (testnet)
In order to create collections or mint NFTs on Polygon running on testnet, you will need some "test MATIC" since this is what is spent to process transactions on the Polygon chain.
Watch the video for a walkthrough on how to get testnet MATIC or see below for step-by-step instructions.
Log into Enefits X and then click on the dropdown box in the upper right corner. Then click on Account. You'll see your address (it starts with 0x...). Copy this address to your clipboard using Ctrl-C or Option-C.
Visit http://mumbaifaucet.com or http://faucet.polygon.technology - both offer free testnet MATIC.
Paste the address you copied in Step 1 into the address field and submit the form. You should be able to go to http://mumbai.polygonscan.com and search by your address and view the current MATIC balance of the public ETH/MATIC address associated with your Enefits X account.
To verify that your MATIC is available to your Enefits X account, refresh the Account screen and you should see your testnet MATIC balance update with a value greater than zero.
Now mint some NFTs with Enefits X!
