- nathias 5y agoI think its doable. You implement minting contract to be triggered by scanning QR code, and each minting contract to self-destruct/stop working after minting one token. You also need to have a treasury where the 10 dollars would live, either another smart-contract prefilled with stable coins that are redeemable from sending the token to the contract.
