I've created some NFTs on the Solana Blockchain and now have them in my Phantom Wallet.
How would I create a website that checks the users' wallet to see which NFTs they have in it, eg to make them available in a web based game I might create?
I can't see any info on this in the Phantom docs but it must be possible since sites like Solsea do this.
Any pointers appreciated!
If you haven't got the user to connect their wallet at this point, I would recommend the anchor wallet library.
Some relevent resources can be found here for actually retrieving solana nft metadata:
