🔍 Component Overview

SeedBackupView.vue is a critical security component that allows users to view and backup their seed phrases and derivation paths. This is essential for account recovery and security.

Core Functionality

1. Seed Phrase Display: Reveals user's mnemonic seed phrase with security warnings
2. Derivation Path Display: Shows the derivation path for key generation
3. Clipboard Integration: Copy seed phrase and derivation path to clipboard
4. Security Features: Requires explicit reveal action before showing sensitive data
5. Multi-Account Support: Shows warnings for users with multiple accounts

User Journey

• User navigates to seed backup from account settings
• Component loads active account data
• User sees security warnings about seed phrase exposure
• User clicks "Reveal my Seed Phrase" button
• System displays seed phrase and derivation path
• User can copy each value to clipboard
• Temporary "Copied" feedback is shown

Security Considerations

• Critical Security Component: Contains highly sensitive cryptographic material
• Recovery Essential: Required for account recovery and cross-device access
• Privacy Sensitive: Seed phrases must be protected from exposure
• Multi-Account Awareness: Warns users about multiple account scenarios

📋 Migration Requirements Analysis

✅ Phase 1: Database Migration (Estimated: 2-3 minutes)

Current Legacy Patterns:

// 🔴 Legacy pattern - databaseUtil import
import * as databaseUtil from "../db/databaseUtil";

// 🔴 Legacy pattern - settings retrieval
const settings = await databaseUtil.retrieveSettingsForActiveAccount();

Required Changes:

// ✅ Modern pattern - PlatformServiceMixin
import { PlatformServiceMixin } from "@/utils/PlatformServiceMixin";
mixins: [PlatformServiceMixin],

// ✅ Modern pattern - mixin methods
const settings = await this.$accountSettings();

✅ Phase 2: SQL Abstraction (Estimated: 1-2 minutes)

Assessment: No raw SQL queries detected in component

• Component uses utility functions for account retrieval
• No direct database operations requiring abstraction
• Action: Verify no hidden SQL patterns exist

✅ Phase 3: Notification Migration (Estimated: 3-4 minutes)

Current Notification Patterns:

// 🔴 Direct $notify usage - Error notification
this.$notify(
  {
    group: "alert",
    type: "danger",
    title: "Error Loading Profile",
    text: "Got an error loading your seed data.",
  },
  3000,
);

Required Changes:

// ✅ Helper system + constants
import { createNotifyHelpers, TIMEOUTS } from "@/utils/notify";
import { NOTIFY_PROFILE_LOAD_ERROR } from "@/constants/notifications";

// ✅ Usage with helpers
this.notify.danger(NOTIFY_PROFILE_LOAD_ERROR, TIMEOUTS.STANDARD);

✅ Phase 4: Template Streamlining (Estimated: 2-3 minutes)

Current Template Patterns:

<!-- 🔴 Inline conditional classes -->
<span v-show="!showCopiedSeed" class="text-sm text-green-500">
<span v-show="showCopiedDeri" class="text-sm text-green-500">

<!-- 🔴 Button styling repetition -->
<button class="block w-full text-center text-md uppercase bg-gradient-to-b from-slate-400 to-slate-700 shadow-[inset_0_-1px_0_0_rgba(0,0,0,0.5)] text-white px-1.5 py-2 rounded-md">

Required Changes:

// ✅ Computed properties for cleaner template
computed: {
  seedCopiedClass() { return "text-sm text-green-500"; },
  revealButtonClass() { return "block w-full text-center text-md uppercase bg-gradient-to-b from-slate-400 to-slate-700 shadow-[inset_0_-1px_0_0_rgba(0,0,0,0.5)] text-white px-1.5 py-2 rounded-md"; }
}

🧪 Testing Strategy

Critical Functionality to Verify:

1. Seed Phrase Display: Verify seed phrase reveals correctly
2. Derivation Path Display: Verify derivation path shows correctly
3. Clipboard Operations: Test copy functionality for both seed and derivation path
4. Security Warnings: Verify warning messages display appropriately
5. Multi-Account Detection: Test behavior with multiple accounts
6. Error Handling: Test error scenarios (missing account, loading failures)

Edge Cases to Test:

1. No Active Account: Component behavior when no active account exists
2. Missing Seed Data: Handling of accounts without mnemonic data
3. Multiple Accounts: Proper warning display for multi-account scenarios
4. Clipboard Failures: Graceful handling of clipboard API failures
5. Network Errors: Error handling for database/settings loading failures

Security Testing:

1. Seed Phrase Protection: Verify seed is hidden by default
2. Reveal Mechanism: Test that reveal button functions correctly
3. Copy Feedback: Verify clipboard operations work securely
4. Data Exposure: Ensure no accidental data exposure in logs or errors

📊 Migration Complexity Assessment

Complexity Factors:

• Database Operations: 1 database operation (Low complexity)
• Notification Patterns: 1 notification type (Low complexity)
• Template Logic: Minimal inline logic (Low complexity)
• Security Sensitivity: High (Critical security component)
• User Impact: High (Essential for account recovery)

Risk Assessment:

• Functionality Risk: Low (simple component functionality)
• Security Risk: High (critical security component)
• Data Risk: Low (no data transformation required)
• User Impact: High (essential for account backup)

Estimated Time Breakdown:

• Phase 1 (Database): 2-3 minutes
• Phase 2 (SQL): 1-2 minutes (minimal work)
• Phase 3 (Notifications): 3-4 minutes
• Phase 4 (Template): 2-3 minutes
• Total Estimated: 8-12 minutes
