The purpose of this project was to try to put a Mario-Style game inside of an NFT.
While I was successfully able to put an interactive web game inside of an NFT, one aspect of the game does not work at the moment. Upon winning the game, one's Crypto Wallet (e.g. MetaMask) should activate sending a congratulations message. Due to the configuration of OpenSea's (& Rarible's) sandboxed environment used for displaying dynamic NFTs it runs into an issue with CORS same-origin-policy. If this issue were solved, it could allow for some really incredible functional NFTs. Typically, Metadata used for dynamic NFTs are stored under the metadata tag: "animation_url", however this is not standardized. For truly incredible dynamic NFTs there must be some level of standardization so dynamic NFTs can operate consistently regardless of platform it is hosted on.
If there are any workarounds to this issue allowing the user to successfully connect to their wallet from within these sandboxed environments, please share 😀
