If the string `{id}` exists in any URI, clients MUST replace this with the actual token ID in hexadecimal form. This allows for large number of tokens to use the same on-chain string by defining a URI once, for a large collection of tokens. Example of such a URI: `https://token-cdn-domain/{id}.json` would be replaced with `https://token-cdn-domain/000000000000000000000000000000000000000000000000000000000004CCE0.json` if the client is referring to token ID 314592/0x4CCE0. +The URI value allows for ID substitution by clients.

The string format of the substituted hexadecimal ID MUST be leading zero padded to 64 hex characters length if necessary.
