Ah thankyou! In that course we did write a web frontend that interacts with the contract ABI to mint the NFTs, but we didn’t do the display side. I’m curious how opensea are doing it, because they can display NFTs from my contract without me ever giving them the ABI. Can you go from decompiled contract (like etherscan can generate) -> ABI maybe?
- miracle2k 5y agoWhen you are implementing an NFT, you are likely implementing either the ERC 721 or the ERC 1155 interfaces; as such, certain standard functions will be available using a standard ABI call. So OpenSea will just try to call `tokenURI`; if you have implemented the interface correctly, that will succeed, if not, OpenSea will not show a placeholder image.
