I’m unsure honestly, is that what proof uses?

Can you link the Proof you're looking at? There are so many on OS...

They're using ERC721. So each token is unique, even if they currently have the same metadata. It looks like they set a baseURI in the contract, which returns some JSON with the image source: https://collective.proof.xyz/token-metadata/proof-pass/metadata.json

@0xwaw You can see the baseURI on Etherscan along with the rest of the contract https://etherscan.io/address/0x08d7c0242953446436f34b4c78fe9da38c73668d#readContract#F2

@0xwaw they could change the JSON they are referencing to update the image, either for all users, or for individual tokens if they wanted to down the line. Contract is here: https://etherscan.io/address/0x08d7c0242953446436f34b4c78fe9da38c73668d#code#F1#L1
