ERC1155 Convert uint to hexadecimal

[Andon_Mitev]

I'm having erc1155 smart contract which is using following base url: https://token-cdn-domain/{id}.json. When i try to get the uri for token with id 5 for example i receive this: https://token-cdn-domain/5.json but in ipfs they are stored with leading zero padded to 64 hex characters length and 5 looks like this 0000000000000000000000000000000000000000000000000000000000000005.json any idea how to provide the correct uri?

Hello @Andon_Mitev

I have not tested, and I cannot guarantee that this would work, but have you tried this kind of python formating?

https://token-cdn-domain/{id:064}.json

Here is an implementation in JavaScript as well:

ERC1155 uri function doesn't use the tokenID?

Here's an implementation in JavaScript: const makeUri = (uri, id) => uri.replace('{id}', id.toString(16).padStart(64, '0')); > makeUri('ipfs://uri/{id}.json', 250) 'ipfs://uri/00000000000000000000000000000000000000000000000000000000000000fa.json'
