How can I mint my badges?
Ensure you are on the latest version of the app by checking the Apple Appstore or Google Playstore. Once you have updated to the latest version, tap your account icon on the top left and select the badge you would like to mint. You should see a Mint as NFT button there. Tap that and complete the purchase to get it minted.
Can I use an ERC-20 (Ethereum) Wallet to store my NFT?
The badge NFTs are minted on the Polygon Network rather than the Ethereum Network, so you will need to change which network you are pointing to with your Wallet to see it. You can easily see your minted NFTs by going to the account screen in COIN and tapping See All in the badges section, then tapping the View All Minted NFTs button.
Currently, badges minted as NFTs are simple collectibles that you can store in your crypto wallet, but we may introduce functionality for some or all of them in the future.
