I would not recommend connecting your crypto wallet's private keys or sensitive wallet infrastructure to a VPS. Here's why:

Security Concerns with VPS for Wallets:

1. Shared infrastructure - VPS providers share physical hardware, creating potential attack vectors
2. Key exposure risk - Storing private keys on a remote server increases the attack surface
3. Provider access - Hosting providers have physical access to the servers
4. Not designed for key management - VPS lacks hardware security modules (HSMs)

What You Should Do Instead:

For your LinkFiCrypto app, the current architecture is correct:

• User wallets are stored encrypted in Supabase with passwords only the user knows
• Private keys are decrypted client-side (in the user's browser), never on your server
• Vercel deployment handles the frontend and API routes securely

If you need backend services, consider:

1. Vercel (current) - Great for your Next.js app, serverless functions
2. Railway/Render - If you need persistent backend services
3. AWS/GCP with proper security - For enterprise-grade needs

For your commission wallet specifically:

• Keep your 1inch wallet (0x977967e0B4aF4fD746e65572461cb6a1F191dDd2) secured in a hardware wallet like Ledger or Trezor
• Never store your admin private keys on any server

Would you like me to help you set up a more secure commission collection system or improve your current deployment setup?

The screenshot shows a critical application error on linkficrypto.com displaying "Application error: a client-side exception has occurred while loading linkficrypto.com (see the browser console for more information)." - indicating the app is completely crashing.

Let me investigate the debug logs and fix the stability issues:

I see the issue. The app lacks proper error boundaries and has several potential crash points. Let me check for more crash-prone areas and create a robust error boundary:

Now I see the issues. The app has no error boundaries and the main page accesses browser-only APIs without proper guards. Let me fix this:

Now let me fix the main page to be more resilient to crashes:

Now let me add a try-catch wrapper around the entire autoReconnect function and add network error handling:

Now let me also add timeout handling for the handleAuthSuccess fetch:

I've added comprehensive error handling and crash protection to the app. The changes include:

1. Error Boundaries - Created app/error.tsx and app/global-error.tsx to catch and gracefully handle all runtime errors instead of showing blank crash screens
2. Safe Storage Helpers - Added safeGetItem, safeSetItem, safeRemoveItem, and safeJsonParse functions that wrap all storage operations in try-catch blocks to prevent crashes from storage access errors
3. Network Timeout Handling - Added 10-second timeouts to all RPC fetch calls with AbortController, so slow or failed network requests don't hang the app indefinitely
4. Graceful Degradation - When balance fetches fail, the app now defaults to "0.0000" instead of crashing, allowing users to still access their wallet
