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.
