Currently I'm writing an app to interact with NFTs in a game. Therefore I want to implement a function to buy and sell an NFT by using a QR code.
The seller should be able to create a QR code for his token including the price and obviously his address. The buyer just scans the code and sends the amount plus gas fees. He shall not be able to edit the amount. The NFT should then be transfered to the user.
Since the app/mod is inside a game there is no option to use a browser. Does anyone has some links or information for me that could help?
