Balances Displayed & Send Enabled When Wallet Disconnected

[williamluke4]

Currently, the application displays token balances and allows users to attempt sending transactions even when their wallet is disconnected. This seems to persist even after logging out.

Steps to Reproduce:

1. Connect a wallet and observe the displayed balances.
2. Disconnect or log out of the wallet.
3. Notice that balances are still shown.
4. Navigate to the vouchers/pools page and observe that the "Send" button is still active.

Expected Behavior:

• When a wallet is disconnected, balances should not be displayed.
• The application should prevent any actions that require a connected wallet (e.g., sending transactions) and instead prompt the user to connect/sign in.

Additional Notes:

This issue likely stems from the application maintaining an authenticated session even when the wallet connection is lost. This could potentially lead to user confusion and unexpected behavior.

Severity: Medium (potential for user confusion and unintended actions)

Proposed Solution (Optional):

• Implement a check to ensure the wallet is actively connected before displaying balances or enabling transaction-related actions.
• Clear any relevant session data upon wallet disconnection to prevent unintended access.
