Issue: No Error Icon or Immediate Visual Feedback for Invalid Private Key

• Description: The "Import wallet with private key" interface fails to provide immediate visual feedback or a specific error icon when a user enters an incorrectly formatted or invalid private key.

• Observed Behavior:

  • When a user inputs a string that does not meet the technical requirements of a private key (e.g., incorrect length or characters), the UI does not show a real-time error icon (such as a red "X" or exclamation mark) inside the text field.

  • The user may have to attempt to proceed before receiving any notification, leading to a "guessing game" regarding whether the pasted key was captured correctly.

• Expected Behavior:

  • The input field should perform real-time validation.

  • If the key is invalid, a red error icon should appear within the field along with a clear descriptive message: "Invalid Private Key format".
