Once you've claimed an NFT or participated in the marketplace, you can view your collection on your Nifty's profile.
You'll want to visit your personal profile page at niftys.com/yourusername then tap on “Collected” to see what NFTs are in your collection.
What if I own multiple of the same NFT? Where will those be displayed?
If you own multiples of the same NFT, the multiples won't all be displayed on your profile. In order to see how many you own, you'll want to click on the NFT itself and locate the top of the marketplace. An indicator will appear which will display how many you own.
