OID4VCI Pre-Authorized Code

Wallet resolves a credential offer URI, discovers issuer metadata, exchanges a pre-authorized code for an access token, obtains c_nonce from the Nonce Endpoint, and requests a Verifiable Credential bound to a proof JWT.

OID4VCI Pre-Authorized Code + tx_code

Pre-authorized credential issuance with mandatory transaction code enforcement at token exchange — the offer's grant block declares a tx_code object requiring wallet to include a user-entered code (OID4VCI §6.1).

OID4VCI Deferred Credential Issuance
