A Badger is a unique type of NFT developed by XLabs on top of the Metaplex token standard.
Instead of pointing to assets hosted on the permaweb, a Badger's metadata URI is set to a dynamic endpoint which is connected to XLabs architecture.
What this means is...
Each wallet can mint only one Badger at a time.
You can use as many wallets as you like.
They cannot be transferred.
They cannot be sold.
If you no longer want your Badger, you can burn it using the Badger app, and reclaim some SOL.
You can always mint another in the future.
Badgers are a collection of infinite size.
