+# Project Analysis - 20 Critical Issues Identified
+
+## Critical Bugs (5)
+
+### 1. Critical Bug in usePiggyBank Hook - Contract Address/ABI Parameter Swap
+**Location:** `frontend/src/hooks/usePiggyBank.ts:92-103`
+**Severity:** Critical
+**Description:** The `useReadContract` calls have parameters in wrong order (address and abi swapped), causing contract calls to fail.
+**Expected Behavior:** Contract should read owner and calculate totals properly
+**Suggested Fix:** Swap parameters to correct order in all useReadContract calls
+
+### 2. ABI Mismatch - Missing Contract Functions
+**Location:** `frontend/src/config/contracts.ts`
+**Severity:** High
+**Description:** The ABI is missing several functions that exist in the actual Solidity contract (pause, unpause, transferOwnership, isUnlocked)
+**Expected Behavior:** Frontend should have complete ABI matching the deployed contract
+**Suggested Fix:** Update ABI to include all contract functions and events
+
+### 3. Network Hardcoding in WalletInfo
+**Location:** `frontend/src/components/WalletInfo.tsx:94`
+**Severity:** Medium
+**Description:** Explorer URL is hardcoded to Base Sepolia, won't work for other networks
+**Expected Behavior:** Should show correct explorer based on current network
+**Suggested Fix:** Dynamically determine explorer URL based on network ID
+
+### 4. Input Validation Vulnerability in PiggyBankDashboard
+**Location:** `frontend/src/components/PiggyBankDashboard.tsx:94-95`
+**Severity:** High
+**Description:** DOM manipulation using querySelector without proper validation, potential XSS risk
+**Expected Behavior:** Should use React state management instead of DOM manipulation
+**Suggested Fix:** Use controlled components with proper validation
+
+### 5. Missing Error Boundaries Implementation
+**Location:** App level component
+**Severity:** Medium
+**Description:** No error boundaries to handle component crashes gracefully
+**Expected Behavior:** Should catch and display errors gracefully instead of crashing
+**Suggested Fix:** Implement error boundaries around main components
+
+## Security Issues (4)
+
+### 6. Missing Input Sanitization
+**Location:** Multiple form components
+**Severity:** High
+**Description:** User inputs are not sanitized before processing
+**Expected Behavior:** All user inputs should be validated and sanitized
+**Suggested Fix:** Add input validation and sanitization utilities
+
+### 7. Local Storage Data Leak
+**Location:** `frontend/src/components/PiggyBankDashboard.tsx`
+**Severity:** Medium
+**Description:** Saved state data not encrypted, potential privacy concern
+**Expected Behavior:** Sensitive data should be encrypted or validated
+**Suggested Fix:** Add data encryption or validation for stored data
+
+### 8. Missing CSP Headers Configuration
+**Location:** Vite config
+**Severity:** Medium
+**Description:** No Content Security Policy headers configured
+**Expected Behavior:** Should have proper CSP headers for security
+**Suggested Fix:** Add CSP configuration in vite.config.ts
+
+### 9. Transaction State Not Persisted
+**Location:** Transaction handling throughout app
+**Severity:** Low
+**Description:** Transaction states not persisted, lost on page refresh
+**Expected Behavior:** Should maintain transaction history across sessions
+**Suggested Fix:** Add transaction persistence to localStorage or state
+
+## Performance Issues (3)
+
+### 10. Missing Environment Validation on Startup
+**Location:** App initialization
+**Severity:** Medium
+**Description:** Environment variables not validated until first use, causing silent failures
+**Expected Behavior:** Should validate all required environment variables on app startup
+**Suggested Fix:** Add startup validation function
+
+### 11. Inefficient Component Re-renders
+**Location:** Multiple components
+**Severity:** Medium
+**Description:** Components re-render unnecessarily due to missing memo and useCallback
+**Expected Behavior:** Components should only re-render when necessary
+**Suggested Fix:** Add React.memo, useMemo, and useCallback where appropriate
+
+### 12. No Caching Strategy for Contract Calls
+**Location:** `frontend/src/hooks/usePiggyBank.ts`
+**Severity:** Low
+**Description:** Contract calls are made frequently without caching
+**Expected Behavior:** Should cache contract data to reduce RPC calls
+**Suggested Fix:** Implement caching with React Query or similar
+
+## Code Quality Issues (4)
+
+### 13. Missing TypeScript Strict Mode
+**Location:** tsconfig.json
+**Severity:** Medium
+**Description:** TypeScript strict mode not enabled, missing type safety
+**Expected Behavior:** Should enable strict TypeScript checking
+**Suggested Fix:** Enable strict mode in tsconfig.json
+
+### 14. Console.log Statements in Production Code
+**Location:** Multiple files (PiggyBankDashboard, diagnostics)
+**Severity:** Low
+**Description:** Debug console statements not removed for production
+**Expected Behavior:** Should remove or conditionally include debug statements
+**Suggested Fix:** Add proper logging utility with environment checks
+
+### 15. Inconsistent Error Handling
+**Location:** Throughout application
+**Severity:** Medium
+**Description:** Error handling patterns are inconsistent across components
+**Expected Behavior:** Should have consistent error handling patterns
+**Suggested Fix:** Create centralized error handling utility
+
+### 16. Missing Loading States
+**Location:** Components making async calls
+**Severity:** Low
+**Description:** Some components don't show loading states during async operations
+**Expected Behavior:** Should show loading states for all async operations
+**Suggested Fix:** Add loading states to all async operations
+
+## Testing Gaps (3)
+
+### 17. Missing Unit Tests for Custom Hooks
+**Location:** `frontend/src/hooks/`
+**Severity:** High
+**Description:** Custom hooks have no unit tests
+**Expected Behavior:** All hooks should have comprehensive unit tests
+**Suggested Fix:** Add unit tests for usePiggyBank, useTimelock, useWalletHistory hooks
+
+### 18. Incomplete E2E Test Coverage
+**Location:** `frontend/e2e/`
+**Severity:** Medium
+**Description:** E2E tests only cover basic deposit flow, missing edge cases
+**Expected Behavior:** Should have comprehensive E2E test coverage
+**Suggested Fix:** Add E2E tests for withdraw, error handling, network switching
+
+### 19. No Integration Tests
+**Location:** Testing setup
+**Severity:** Medium
+**Description:** No integration tests for contract interactions
+**Expected Behavior:** Should have integration tests for contract interactions
+**Suggested Fix:** Add integration tests using mocked contract calls
+
+## Documentation & UX Issues (1)
+
+### 20. Missing Accessibility Features
+**Location:** UI components
+**Severity:** Medium
+**Description:** No ARIA labels, keyboard navigation, or screen reader support
+**Expected Behavior:** Should be accessible to users with disabilities
+**Suggested Fix:** Add ARIA labels, keyboard navigation, and accessibility features
+
