Hey everyone, (or whoever should happen to find this thread) I'm Rhyot, an electronic music artist and I suppose now 'new solidity developer'. I'm essentially writing a smart contract to mint a collection of music NFTs to deploy a set collection amount of .mp4 ERC721 tokens to the blockchain, each …

Hey @rhyot , welcome! If I understand correctly, most of the problems you're having right now are related to concatenating strings. Every string in solidity is a list of bytes, so you can parse bytes into string and vice-versa relatively easily: function toBytes(string memory a) public pure retur…

Thanks so much @ernestognw ! I really appreciate you popping by to help. So I was running into a weird issue where abi.encodePacked was actually causing the safeMint to revert, but by dropping 'Packed' for abi.encode the transactions would work without a problem. The concatenations are all working …

No problem, happy to help. So I was running into a weird issue where abi.encodePacked was actually causing the safeMint to revert, but by dropping 'Packed' for abi.encode the transactions would work without a problem. :warning: Beware there are differences between encode and encodePacked that m…

Interesting, so it seems that there isn't actually an ERC721 function to name the NFTs, and that there isn't a way to say, mint 100 of the same NFT using a singular metadata.json and a singular MP4, and have the contract itself name and mint them separately? I wanted to kind of make an open edition…

Woo, okay got it all working! Thank you @ernestognw . Basic understanding of the process achieved. I was able to get everything to work the way I needed by writing a metadata python script that added padded 0's to the name (Rhyot - Genesis #013) but didn't append that to the .json file names, didn't …

mint 100 of the same NFT using a singular metadata.json and a singular MP4, and have the contract itself name and mint them separately? There is a way of having the same metadata for all the tokens of the same kind, but ERC721 is not suitable for that, take a look to ERC1155 the contract would …

Flattening and verifying, the new boss fight. Being as I deployed this on Remix, I found that I could simply flatten using the available flattener plugin by navigating to the contract in the explorer, right click > flatten, then go down to the flattener tab, and viola - right? WELL. Interestingly, …

Update: Moved over to my PC, ran the VS Code setup for truffle, got a flattened contract to output, and now running into the ominous " But we were unable to locate a matching bytecode (err_code_2)" I have a bad feeling that something about deploying via Remix but having to flatten via Truffle has c…

[image] rhyot: I have a bad feeling that something about deploying via Remix but having to flatten via Truffle has created some issues and I may not be able to get this to verify. This could be the case. Unfortunately deploying via Remix is not the best way to guarantee verifiability. If you…

Yeah things definitely got a little challenging there, and unfortunately it took a redeploy to fix, but thankfully I've got everything up and live, verified, minted, voila. Just trying to get rarible to hide the collection now. I didn't consider the value of a burn or self destruct function, but in …

This could be the case. Unfortunately deploying via Remix is not the best way to guarantee verifiability.
