Test the end-to-end journey
Walk through sample credential issuance and presentation with the repository components.
What you can evaluate
Start with one high-friction credential check
Choose one credential journey, test how the issuer, holder wallet, verifier, and client fit together, and document the gaps before deciding whether to invest in deployment.
Map integration ownership
See how the holder wallet, verifier, and relying-party client connect through the TypeScript SDK.
Make a go/no-go decision
Agree success criteria and list the interoperability, security, privacy, and operational gaps before planning production.
What it includes
What the repository demonstrates
A modular demo architecture covering issuer, verifier, holder wallet, and client SDK. The repository is a technical reference; it does not claim certification, regulatory compliance, or production readiness.
Key capabilities
- A sample credential issuance flow using OID4VCI and holder proof.
- A sample presentation flow using OID4VP and verifier-side authorization.
- TypeScript SDK with PKCE, callback handling, and token lifecycle management.
- An Ionic/Angular sample wallet for QR-based issuance and presentation journeys.
- Shared Java foundation to reduce duplication and simplify maintenance.

Verification flow (OID4VP)
sequenceDiagram
participant U as User
participant C as Client App
participant W as Wallet
participant V as Verifier
C->>V: Start verification
V-->>C: Presentation request (QR/link)
U->>W: Scan and consent
W->>V: Verifiable Presentation
V-->>C: Verification result + token
Evaluation path
Scope a focused pilot in three steps
Keep the first evaluation to one credential and one relying-party journey.
Pick the workflow
Define the credential, who issues it, which wallet holds it, and which service needs to verify it.
Run the sample journey
Use the demo components to examine issuance, wallet presentation, and the verifier-facing client integration.
Decide what it takes
Record test results and the security, privacy, interoperability, operations, and compliance work still needed.
FAQ
Questions about the demo
What is an SSI platform?
An SSI (Self-Sovereign Identity) platform enables verifiable digital credentials, with user-controlled data and service-side cryptographic verification.
Which flows does the demo show?
OID4VCI handles issuance of digital credentials to the wallet. OID4VP handles credential presentation and verification during login, onboarding, or authorization.
Is this certified or production-ready?
It is presented as a demo and integration reference. The repository does not establish protocol conformance, EUDI Wallet or eIDAS compliance, security assurance, or production readiness. These require separate evidence and deployment-specific assessment.
Why use it in an enterprise context?
Potential benefits depend on the credential, wallet, verifier, and operating model selected. This demo does not establish fraud reduction or regulatory compliance for a deployed service.
Have one credential workflow to test?
Start with the README, agree on success criteria, and use the demo to scope a focused integration pilot.
