What this diagram shows

This diagram details a robust error handling process. It starts with a user action attempting an operation. If the operation fails, an error is caught and then categorized into types like Wallet, Network, Contract, or Input Validation. Based on the error type, specific user instructions or information are displayed (e.g., wallet instructions, network info, contract status, or highlighting invalid fields). Finally, the user is given an option to retry the operation.

When to use it

Use this diagram when designing user-facing applications that require resilient error handling, especially for operations that might fail due to external factors (network, API, blockchain interactions) or user input issues. It's ideal for ensuring a clear and helpful user experience during failures.

How to adapt it for your project

This flow can be adapted by adding more specific error categories relevant to your application's domain, integrating with logging or monitoring systems, implementing different retry strategies (e.g., limited retries, exponential backoff), or incorporating fallback mechanisms instead of just retrying.
