# OpenPassportVerifier

The `OpenPassportVerifier` class is designed to facilitate the verification of user credentials and disclosures in applications using the OpenPassport system. It supports various modes of operation, allowing for both on-chain and off-chain proof verification. The class provides methods to configure verification parameters such as minimum age, nationality, and OFAC checks, and to generate intents for user interactions.
