Links
Tokens may be linked to any resource, either tokens or off-chain resources. This has many uses such as creating a record of a token mint or even building a decentralized redirect service.
Links are created using the loc field which is used by wallets in a similar way to the HTTP location header.
To create a link the loc field is set to either a number, bytes or string:
location = number / bytes / string
number- Link to a token with given output index and transaction ID matching the link refbytes- Link to a token given as ref bytesstring- Link to any URI
