- [ ] Add gas limit validation
- [ ] Test: All invalid inputs rejected
### Race Conditions
- [ ] Add approval locking mechanism (`contexts/TransactionContext.tsx`)
- [ ] Make approval updates atomic
- [ ] Add duplicate approval prevention
- [ ] Test: Concurrent approvals handled correctly
### Storage Security
- [ ] Implement encrypted storage (`utils/encryption.ts`)
- [ ] Replace all localStorage with SecureStorage
- [ ] Generate secure encryption keys
- [ ] Test: Data encrypted and decryptable
### Transaction Security
- [ ] Add nonce management (`contexts/TransactionContext.tsx`)
- [ ] Add transaction deduplication
- [ ] Add transaction expiration
- [ ] Test: Duplicate transactions prevented
### Provider Security
- [ ] Add provider verification (`contexts/TransactionContext.tsx`)
- [ ] Verify account matches wallet
- [ ] Reject unverified providers
- [ ] Test: Fake providers rejected
---
## Phase 2: High Priority Fixes (Week 2)
### Integer Overflow
- [ ] Replace all parseInt with BigNumber (`components/Body/index.tsx`)
- [ ] Fix value parsing in transaction creation
- [ ] Fix value display formatting
- [ ] Test: Large values handled correctly
### Gas Management
- [ ] Add maximum gas limit (`contexts/TransactionContext.tsx`)
- [ ] Validate gas prices
- [ ] Add gas estimation limits
- [ ] Test: Excessive gas rejected
### Input Sanitization
- [ ] Sanitize all user inputs (`components/TransactionExecution/TransactionBuilder.tsx`)
- [ ] Validate transaction data length
- [ ] Prevent XSS in address fields
- [ ] Test: Malicious inputs sanitized
### API Security
- [ ] Move API keys to environment variables (`helpers/relayers/index.ts`)
- [ ] Add API key rotation mechanism
- [ ] Add request signing
- [ ] Test: API keys not exposed
### Transaction Limits
- [ ] Add maximum transaction value
- [ ] Add daily transaction limits
- [ ] Add rate limiting
- [ ] Test: Limits enforced
### Network Security

## Quick Fix Reference
### Replace These Patterns:
**❌ BAD:**
```typescript
parseInt(value, 16)
Math.random().toString(36).substr(2, 9)
postMessage(msg, "*")
localStorage.setItem(key, JSON.stringify(data))
```
**✅ GOOD:**
```typescript
ethers.BigNumber.from(value)
generateSecureId()
postMessage(msg, specificOrigin)
await secureStorage.setItem(key, JSON.stringify(data))
```
---
## Testing Commands
```bash
# Run security tests
npm test -- security.test.ts
# Run linting
npm run lint
# Check dependencies
npm audit
npm audit fix
# Build and check for errors
npm run build
```
