There is no single deployment model of a Wallet: Verifiable Credentials and keys can both be stored and managed locally, or by using a remote self-hosted service, or a remote third-party service. In the context of this specification, during Credential Issuance the Wallet acts as an OAuth 2.0 Client (see [@!RFC6749]) towards the Credential Issuer which acts as the OAuth 2.0 Authorization Server / Resource Server.
