In this workshop we'll build a Verifier, or VC-gated dapp, that authenticates users based on a Polygon ID Verifiable Credential. Verifiers can set up queries based on users’ existing Credentials collected from a broad set of Issuers. A Query encapsulates the criteria that a user must match to authenticate, such as “must be a member of Developer DAO” or “must be over 18 years old” to authenticate and use the dapp.
