#Overview

The Issuer2 Service provides several configuration options to customize its behavior and appearance. This section covers:

• Display Configuration – Configure how your issuer appears in wallets.
• Credential Types – Manage supported credential configurations.
• Status List Aggregation – Discover and cache status lists for offline verification.
• Rate Limiting – Configure request limits and Redis-backed failure backoff for OID4VCI endpoints
• Signed Credential Issuer Metadata – Request and verify OpenID4VCI metadata as a signed JWT.
• Client Authentication & Attestation – Configure clientAuthenticationConfig (anonymous pre-authorized access and/or attestation-based wallet authentication).

#Configuration Hierarchy

Configuration in the Issuer2 Service follows a hierarchy:

1. Service Configuration – Base settings defined when creating the issuer service.
2. Credential Profiles – Per-credential-type settings that override service defaults.
3. Offer Overrides – Per-offer settings that override profile defaults.

This lets you set sensible defaults at the service level while keeping flexibility for specific use cases.
