Implement Authentication State Persistence with Secure Token Management

[grantfox-oss]

Implement persistent authentication state management with secure token storage, automatic refresh logic, and logout safeguards. Current wallet integration lacks session persistence and token lifecycle management, requiring users to reconnect on page refresh.

• Affected files:
  • src/components/providers.tsx
  • src/lib/wallet.ts
  • src/config/environment.ts
  • src/pages/_app.tsx
  • src/lib/stellar.ts
  • src/lib/api/logger.ts
• Acceptance criteria:
  • Implement secure token storage using localStorage with encryption for sensitive data
  • Add automatic token refresh logic before expiration
  • Persist wallet connection state across page reloads
  • Implement logout that clears all auth data and cookies
  • Prevent CSRF attacks with secure token validation
  • Tests verify token refresh, persistence, and cleanup on logout

Hello maintainer, I would love to work on this

[Preciousuche]

Hello Proof-Stell team,

I’d like to work on Issue #34: Implement Authentication State Persistence with Secure Token Management.

I have experience building backend and full-stack applications with TypeScript and JavaScript, and I’ve contributed to several open-source projects involving authentication, API integration, and application architecture. This issue aligns well with my interest in building secure and reliable user authentication flows.

For this task, I plan to:

Review the current authentication flow and identify where session persistence breaks down.
Implement secure authentication state persistence while following best practices for token handling.
Ensure authentication state is restored correctly across page refreshes and browser sessions where appropriate.
Handle edge cases such as expired or invalid tokens, logout, and token refresh.
Keep the implementation modular, maintainable, and consistent with the existing codebase.
Add or update tests to verify authentication persistence and prevent regressions.

My goal is to deliver a secure, well-tested implementation that improves both the user experience and the overall reliability of the authentication system.

Thank you for considering my application. I look forward to contributing to Proof-Stell and collaborating with the team.

Best regards,

[grantfox-oss]
