JWT Payload

When an end user connects their wallet, you, the developer, get a JSON Web Token (JWT) that can be used to verify some claims about the end user, notably a proof of ownership over a wallet public address. After authenticating the JWT token, see Server-side verification, you may want to leverage user and wallet information provided in the JWT. Below we have the content defined with the aim of following the JWT standards.

Standard JWT claims:

sub	Subject of the JWT token. userId in the deprecated info claim.
iat	Timestamp when the JWT token was issued.
exp	Timestamp when the JWT token will expire.

Dynamic-specific claims:
