Best practices for OID4VP integration in React Native

I'm implementing OID4VP verification in a React Native app and wanted to share some best practices I've learned. ## The Challenge Mobile apps have unique constraints: - Deep linking for wallet interactions - Handling app backgrounding during verification - QR code scanning UX ## My Approach ### 1. Universal Links for Callbacks Instead of custom URL schemes, use universal links: ```typescript // Configure universal links in app.json { "expo": { "ios": { "associatedDomains": ["applinks:yourapp.com"] } } } ``` ### 2. State Management Use a verification context to track session state: ```typescript const VerificationContext = createContext<{ sessionId: string | null; status: 'idle' | 'pending' | 'success' | 'failed'; startVerification: () => Promise<void>; }>({...}); ``` ### 3. QR Code Display For desktop-to-mobile flows, generate the QR on the server: ```typescript const { qrCode, sessionId } = await credlyr.verifications.create({ policyId: 'pol_age_verification', format: 'qr', }); ``` ## Questions Has anyone implemented this differently? I'm particularly curious about handling the case where the wallet app isn't installed.
