## Subject

The Subject is the individual or entity that holds a Verifiable Credential and controls the identity associated with it. In the context of decentralized finance, the subject is typically the user who manages their identity via a wallet to interact with various protocols.

The subject is responsible for the secure storage of their private keys and the presentation of credentials when requested by a verifier. By acting as the custodian of their own identity, the subject gains control over which information is disclosed and to whom.

This role is fundamental to the concept of self-sovereign identity, placing the user at the center of the identity lifecycle.
