The second layer validates form inputs before submission, checking for required fields and business rule violations. The third layer handles errors returned by the server API, while the fourth layer ensures users receive clear, actionable feedback about any issues that occur. ### Common Error Scenarios + - **Missing Identifier:** User hasn't selected an active DID - **Negative Amount:** Prevent negative gift values - **Empty Gift:** Require either description or amount @@ -499,6 +537,7 @@ Each error scenario is handled with specific validation logic and user-friendly ## Security Considerations ### Data Privacy + - **DID Protection:** User identifiers only shared with explicit consent - **Local Storage:** Sensitive data encrypted in local database - **Network Transport:** All API calls use HTTPS encryption @@ -506,6 +545,7 @@ Each error scenario is handled with specific validation logic and user-friendly The component maintains strict privacy controls over user data, particularly decentralized identifiers which serve as the core of user identity in the system.
