Actually I do have another question ( Deployment failed on Rinkeby: “ERC721PresetMinterPauserAutoId” hit an invalid opcode ). How do I provide the metadata you mentioned. The uri is pointing to a diretory but I cant see a file name. So Im not sure how to proceed. https//:Mydomain.com/tokens/0 for ex…

Hi @madeindreams , I have moved this question to a new topic. I recommend creating a new topic per question as it makes it easier for community members to answer, (and for future readers to find answers). With the EIP-721 optional metadata extension, each tokenID can have a tokenURI which points t…

Or would it be more effective to use IPFS?

Hi @madeindreams , Did you need more information or did the above reply answer your question? (You can mark it as the solution if it did). Feel free to ask all the questions that you need.

Great explanation! There's a typo in the last paragraph: to store the IPFS has should be: to store the IPFS hash

Hi @Cryptokkie , Thanks, fixed. :pray:

[SOLVED] Hey @abcoathup , I have to hijack this post (sorry :innocent:). How did you managed to make your contract appearing as "My NFT" in OpenSea? We have an issue with ERC1155, that these contracts will be displayed as "Unidentified Contract". Is there anything that you did additionally in order t…

[image] abcoathup: There would be increased minting costs as you would need to store the IPFS hash for each tokenID but it would be more decentralized. What would the order of events be for storing the IPFS hash for each tokenId? Something like: Make hash for every token mint(tokenId, hash…

You will not use baseURI for dynamically minted token sets, which utilize ipfs. If each metadata you're pointing to has nonidentical content, each token will have a unique ipfs hash, i.e., the full URI is ipfs://<content hash> with no tokenId path parameter appended at the end (there's a way to make…
