Erica: Local Verifier Testing Tool

Erica is a public, lightweight, locally-runnable tool designed to help Relying Parties (RPs) accelerate their verifier development and testing. Rather than waiting for integration with the full EUDI Wallet ecosystem, you can use Erica to simulate wallet behavior and test your presentation request handling in isolation.

Key Features

• HAIP Validation: Validates presentation requests against High Assurance Interoperability Profile (HAIP) rules to ensure compliance with EUDI ecosystem requirements
• Wallet Simulation Modes: Test different wallet behaviors and edge cases, including:
• Incorrect or malformed credentials
• Special characters in claims
• Various error scenarios and credential states
• Local Execution: Run entirely on your development machine without external dependencies
• Immediate Feedback: Test your OpenID4VP verifier implementation immediately
• Development Speed: Explore edge cases and validate your implementation quickly before moving to sandbox integration
