Instead of making 10 separate transfers, users make one batch transfer. + +**Benefits**: + +- Saves time (one transaction vs. many) +- Single fee vs. multiple fees +- Clear audit trail +- Atomic operation (all succeed or all fail) + +--- + +#### Key Limitations + +1. **Maximum recipients**: 10 per batch + - Why? Keeps transaction size reasonable + - Workaround: Make multiple batches if needed + +2. **One creator at a time**: Can't mix creators in one batch + - Why? Contract design simplification + - Workaround: Make separate batches per creator + +3. **Liquid balance only**: Can't transfer staked/locked keys + - Why? Only liquid balance is available + - Workaround: Unstake first if needed + +4. **Stellar addresses only**: Recipients must have Stellar wallets + - Why? System uses Stellar blockchain + - Workaround: Help user set up Stellar wallet + +--- + +#### Acceptance Criteria (Must Have) + +✅ **AC1**: Up to 10 recipient rows accepted + +- Implementation: `rows.length <= 10` +- Verified: Can add 1-10 rows + +✅ **AC2**: Add Recipient button disabled at 10 rows + +- Implementation: `canAddMore = rows.length < MAX_RECIPIENTS` +- Verified: Button disabled when 10 rows exist + +✅ **AC3**: Total keys displayed and updated in real-time + +- Implementation: `useMemo` calculates total, updates on row changes +- Verified: Total updates as quantities change + +✅ **AC4**: Invalid address shows row-level error + +- Implementation: Stellar regex validation per row +- Verified: Error appears under invalid address + +✅ **AC5**: Total exceeding balance shows error and disables submit + +- Implementation: Guard clause + disabled state +- Verified: Red alert + disabled button + +--- + +### Section 2: Architecture & Design + +#### Component Hierarchy + +``` +LandingPage +├── PortfolioHoldings (existing) +│ └── PortfolioHoldingRow (updated) +│ └── Transfer button (new) +└── BatchTransferModal (new) + ├── RecipientList + │ └── RecipientRow (multiple) + │ ├── Address input + │ ├── Quantity input + │ └── Remove button + ├── Summary section + │ ├── Available balance + │ ├── Total keys + │ └── Error display + └── Action buttons + ├── Cancel + └── Confirm Transfer +``` + +--- + +#### Data Flow + +``` +User clicks Transfer button + ↓ +Opens BatchTransferModal + ↓ +User adds recipients & quantities + ↓ +Real-time validation (useMemo) + ↓ +User clicks Confirm Transfer + ↓ +Build BatchTransferOrder array + ↓ +Call useBatchTransferMutation + ↓ +Optimistic update (balance reduction) + ↓ +Submit to contract (1200ms simulation) + ↓ +Show success/error toast + ↓ +Invalidate cache (refetch holdings) +``` + +--- + +#### State Management Pattern + +```typescript +// Component state +const [rows, setRows] = useState([]); +const [isSubmitting, setIsSubmitting] = useState(false); + +// Computed state (useMemo) +const validation = useMemo(() => ({ + rowErrors: new Map(...), + totalQuantity: rows.reduce(...), + isValid: checkAllRows(...) +}), [rows, availableBalance]); + +// Mutation state (React Query) +const mutation = useBatchTransferMutation(walletAddress); +// mutation.isPending, mutation.error, mutation.isSuccess +``` + +--- + +### Section 3: Common Tasks + +#### Task: Add Validation Rule + +**Scenario**: "We need to prevent transfers to the user's own address" + +**Steps**: + +1. Open `BatchTransferModal.tsx` +2. Find the `useMemo` validation block +3. Add check: `if (address === userAddress) return "Cannot transfer to own address"` +4. Test: Try transferring to own address +5. Verify: Error shows + +**Code Example**: + +```typescript +const validation = useMemo(() => { + const rowErrors = new Map(); + + rows.forEach(row => { + if (!row.recipientAddress) { + rowErrors.set(row.id, 'Address required'); + } else if (!STELLAR_ADDRESS_RE.test(row.recipientAddress)) { + rowErrors.set(row.id, 'Invalid Stellar address'); + } else if (row.recipientAddress === userAddress) { + rowErrors.set(row.id, 'Cannot transfer to own address'); // NEW + } + // ... more checks + }); + + return { rowErrors, totalQuantity, isValid }; +}, [rows, userAddress]); // Add userAddress to deps +``` + +--- + +#### Task: Change Maximum Recipients + +**Scenario**: "We want to allow 20 recipients instead of 10" + +**Steps**: + +1. Open `BatchTransferModal.tsx` +2. Find: `const MAX_RECIPIENTS = 10;` +3. Change to: `const MAX_RECIPIENTS = 20;` +4. Find: All references to `MAX_RECIPIENTS` +5. Update docs: Change "10 recipients" to "20 recipients" in all docs +6. Test: Verify can add up to 20 +7. Verify: Button disables at 20 +8. Run full test suite + +**Files to Update**: + +- `BatchTransferModal.tsx` (MAX_RECIPIENTS constant) +- `FEATURE_CHECKLIST.md` (acceptance criteria) +- `README_BATCH_TRANSFER.md` (limitations) +- `TROUBLESHOOTING.md` (FAQ) + +--- + +#### Task: Add Recipient Import (CSV) + +**Scenario**: "Users want to import recipient list from CSV file" + +**Steps**: + +1. Create: New component `RecipientImport.tsx` +2. Implement: CSV file parser +3. Integrate: Into `BatchTransferModal.tsx` +4. Validate: Each imported row +5. Test: With sample CSV files +6. Update: Documentation + +**Pseudo-code**: + +```typescript +function handleImportCSV(csvFile: File) { + const content = await csvFile.text(); + const rows = content.split('\n').map(line => { + const [address, quantity] = line.split(','); + return { + id: generateId(), + recipientAddress: address, + quantity: parseInt(quantity), + }; + }); + setRows(rows); +} +``` + +--- + +### Section 4: Debugging Guide + +#### Debug Scenario 1: Transfer button not showing + +**Symptoms**: No Transfer button on portfolio row + +**Diagnosis**: + +1. Check: Is portfolio row visible? (Yes/No) +2. Check: Does creator have balance > 0? (Yes/No) +3. Check: Is screen width > 768px? (Yes/No) +4. Check: Browser console for errors (Yes/No) + +**Solutions**: + +- If portfolio row not visible → check portfolio data +- If balance is 0 → user has no keys to transfer +- If mobile screen → Transfer is in dropdown menu (MoreHorizontal) +- If console errors → check error message + +**DevTools Steps**: + +1. Open DevTools (F12) +2. Check Network tab: Is API request successful? +3. Check Console: Any errors? +4. Check React tab: Is BatchTransferModal mounted? +5. Check Elements: Is button in DOM? + +--- + +#### Debug Scenario 2: Validation not working + +**Symptoms**: Invalid address accepted, or valid address rejected + +**Diagnosis**: + +1. Check: What's the address? (Record it) +2. Check: What's the error message? (Record it) +3. Check: Browser console logs +4. Check: Regex pattern correct? + +**Test Address**: + +```javascript +// In browser console: +const STELLAR_ADDRESS_RE = /^[G][A-Z2-7]{55}$/; +console.log( + STELLAR_ADDRESS_RE.test( + 'GBRPYHIL2CI3WHZDTOOQFC6EB4KJJGUJGU42ZPZNCCVKNLTLNOXBXUL' + ) +); // true +console.log(STELLAR_ADDRESS_RE.test('INVALID')); // false +``` + +**Solutions**: + +- If address is valid but shows error → Check regex +- If address is invalid but accepted → Check validation logic +- If console shows errors → Check error message details + +--- + +#### Debug Scenario 3: Transfer fails after submit + +**Symptoms**: Submit button clicked, then error/nothing happens + +**Diagnosis**: + +1. Check: Browser console for errors +2. Check: Network tab for API request +3. Check: Is mutation state correct? +4. Check: What error message shows? + +**Common Errors**: + +- "Address required" → Missing recipient address +- "Invalid Stellar address" → Wrong format +- "Quantity must be > 0" → Quantity is 0 or negative +- "Insufficient balance" → Total exceeds available +- "Network error" → Connection issue +- "Contract error" → Backend issue + +**Solutions**: + +- Fix validation errors first +- Check network connectivity +- Check contract status +- Check user balance +- Retry operation + +--- + +### Section 5: FAQ + +#### General Questions + +**Q1: How many recipients can I transfer to in one batch?** +A: Maximum 10 recipients per batch. If you need to transfer to more, create multiple batches. + +**Q2: Can I transfer to the same address twice in one batch?** +A: No, the system prevents duplicate recipients. Add quantities together instead. + +**Q3: What if I run out of balance mid-transfer?** +A: The system checks balance before allowing submit. If balance changes, re-validate by clicking Confirm again. + +**Q4: Can I transfer staked/locked keys?** +A: No, only liquid balance. Unstake keys first if needed. + +**Q5: Is there a fee for batch transfers?** +A: One fee per batch, not per recipient. This saves money compared to individual transfers. + +--- + +#### Technical Questions + +**Q6: Where's the code for batch transfer?** +A: Main files: + +- `src/components/common/BatchTransferModal.tsx` - Component (290 lines) +- `src/hooks/useWallet.ts` - Mutation hook +- `src/components/common/PortfolioHoldingRow.tsx` - Transfer button +- `src/pages/LandingPage.tsx` - Integration + +**Q7: How does validation work?** +A: Uses a `useMemo` hook that runs whenever rows change. Checks: + +- Address format (Stellar regex) +- Quantity > 0 +- Total doesn't exceed balance +- Returns error Map keyed by row ID + +**Q8: How is state managed?** +A: Component state for UI (rows, isSubmitting) + React Query mutation for server operations (isPending, error, etc.) + +**Q9: What's the contract integration point?** +A: In `useBatchTransferMutation.ts`, the `mutationFn`. Currently simulates 1200ms - replace with actual contract call. + +**Q10: How do I run tests?** +A: `pnpm test` or `pnpm test:watch`. See TESTING_GUIDE.md for details. + +--- + +#### Troubleshooting Questions + +**Q11: Transfer button won't open modal** +A: Check browser console for errors. Try refreshing page. Check if portfolio row loaded. + +**Q12: Modal opens but looks broken** +A: Clear browser cache (Ctrl+Shift+Delete). Try different browser. Check responsive design. + +**Q13: Can't add more recipients after adding one** +A: Check if error showing on first recipient. Fix validation errors first. Check if at max 10. + +**Q14: Submit button won't click** +A: Likely a validation error. Check all fields red. Fix errors. Ensure balance sufficient. + +**Q15: Transfer fails with network error** +A: Check internet connection. Check contract service status. Retry in a moment. + +--- + +### Section 6: Glossary + +| Term | Definition | +| --------------------- | --------------------------------------------------------- | +| **Batch Transfer** | Sending keys to multiple recipients in one transaction | +| **Recipient** | A wallet address receiving keys | +| **Quantity** | Number of keys to send to a recipient | +| **Liquid Balance** | Keys available to transfer (not staked/locked) | +| **Stellar Address** | Public wallet address starting with 'G', 56 chars total | +| **Validation** | Checking address format and quantity rules | +| **Mutation** | React Query operation (in this case, submitting transfer) | +| **Optimistic Update** | Updating UI before server confirms (for speed) | +| **Rollback** | Reversing optimistic update if server fails | +| **useMemo** | React hook that memoizes computed values | +| **Props** | Data passed from parent to child component | +| **State** | Data managed by component locally | +| **ref** | React reference to DOM element | +| **Modal** | Pop-up dialog window | +| **Toast** | Brief notification message | +| **TypeScript** | JavaScript with type checking | +| **React Query** | Library for managing server state | +| **Contract** | Smart contract on blockchain | +| **tx_hash** | Transaction hash/ID on blockchain | +| **Idempotent** | Operation that produces same result if repeated | + +--- + +### Section 7: Team Member Role Guides + +#### Frontend Developer Guide + +**Your Focus**: + +- Modify component UI/logic +- Add features and fix bugs +- Write unit tests +- Review code from peers + +**Key Skills**: + +- React hooks knowledge +- TypeScript proficiency +- Component design patterns +- Testing frameworks + +**Common Tasks**: + +1.
