transactions`) +transactions.forEach((tx) => { + console.log(`${tx.description}: ${tx.currentSignatures}/${tx.requiredSignatures}`) +}) +``` + +### Emergency Functions + +#### emergencyPause() + +Creates an emergency pause transaction for a contract. + +```typescript +async emergencyPause( + contractAddress: string, + createdBy: string, + reason: string +): Promise +``` + +**Example:** + +```typescript +const pauseTransaction = await contractService.emergencyPause( + '0xPoolFactoryAddress', + 'security_admin', + 'Critical vulnerability detected in pool creation logic' +) + +console.log(`Emergency pause created: ${pauseTransaction.id}`) +``` + +## Cloud Function Integration + +The ContractService integrates with Firebase Cloud Functions through dedicated endpoints: + +### proposeTransaction + +```typescript +const proposeTransaction = onCall(async (request) => { + const contractService = createContractService(request.data.chainId) + return await contractService.proposeTransaction(request.data.proposal, request.auth.uid) +}) +``` + +### addSignature + +```typescript +const addSignature = onCall(async (request) => { + const contractService = createContractService(request.data.chainId) + return await contractService.addSignature(request.data.transactionId, request.data.signature) +}) +``` + +### executeTransaction + +```typescript +const executeTransaction = onCall(async (request) => { + const contractService = createContractService(request.data.chainId) + return await contractService.executeTransaction(request.data.transactionId) +}) +``` + +## Error Handling + +The service uses structured error handling with `AppError` instances: + +```typescript +try { + const transaction = await contractService.proposeTransaction(proposal, userId) +} catch (error) { + if (error instanceof AppError) { + console.log(`Service error: ${error.message} (${error.code})`) + } else { + console.log(`Unexpected error: ${error.message}`) + } +} +``` + +### Common Error Codes + +- `PROPOSAL_CREATION_FAILED`: Failed to create transaction proposal +- `TRANSACTION_NOT_FOUND`: Transaction ID not found +- `INVALID_STATUS`: Transaction in invalid state for operation +- `ALREADY_SIGNED`: Signer has already signed transaction +- `INVALID_SIGNATURE`: Signature verification failed +- `INSUFFICIENT_SIGNATURES`: Not enough signatures to execute +- `EXECUTION_FAILED`: Transaction execution failed on-chain +- `EMERGENCY_PAUSE_FAILED`: Emergency pause creation failed + +## Database Schema + +The service uses Firestore for transaction state management: + +### contract_transactions Collection + +```typescript +{ + // Document ID: transaction hash + id: string + status: TransactionStatusType + safeTransaction: SafeTransaction + signatures: SafeSignature[] + requiredSignatures: number + currentSignatures: number + createdBy: string + createdAt: Timestamp + updatedAt: Timestamp + executedAt?: Timestamp + executionResult?: ExecutionResult + description: string + metadata?: any + chainId: number + safeAddress: string + expiresAt: Timestamp // 7 days from creation +} +``` + +### Firestore Indexes + +Required composite indexes: + +```javascript +// List transactions by chain and safe +chainId ASC, safeAddress ASC, createdAt DESC + +// Filter by status +chainId ASC, safeAddress ASC, status ASC, createdAt DESC + +// Filter by creator +chainId ASC, safeAddress ASC, createdBy ASC, createdAt DESC +``` + +## Security Considerations + +### Signature Verification + +- All signatures are cryptographically verified +- Only Safe owners can sign transactions +- Duplicate signatures are prevented +- Signature replay attacks are mitigated + +### Access Control + +- Only authenticated users can create transactions +- Safe owner verification for signatures +- Admin-only functions for emergency operations +- Backend private key secured in environment + +### Transaction Expiry + +- Transactions expire after 7 days +- Expired transactions cannot be executed +- Automatic cleanup of expired transactions + +### Data Validation + +- All inputs are validated and sanitized +- Ethereum address format validation +- ABI and function call validation +- Batch transaction size limits (max 20) + +## Performance Optimization + +### Caching Strategy + +- Transaction status cached in Firestore +- Safe configuration cached during service lifetime +- ABI interfaces cached for repeated calls + +### Batch Operations + +- Multiple signatures can be collected simultaneously +- Batch transactions execute atomically +- Optimized Firestore queries with pagination + +### Gas Optimization + +- Gas estimation for all transactions +- Dynamic gas price adjustment +- Batch operations reduce individual transaction costs + +## Monitoring & Logging + +### Structured Logging + +All operations include structured logging: + +```typescript +{ + "level": "INFO", + "function": "ContractService.proposeTransaction", + "transactionId": "0x...", + "safeAddress": "0x...", + "chainId": 80002, + "createdBy": "user123", + "description": "Create lending pool", + "requiredSignatures": 3, + "timestamp": "2023-12-01T12:00:00Z" +} +``` + +### Key Metrics + +- Transaction creation rate +- Signature collection time +- Execution success rate +- Error frequencies +- Gas usage patterns + +### Alerting + +Recommended alerts: + +- Failed transaction executions +- High error rates +- Unusual signature patterns +- Expired transaction buildup +- Emergency pause activations + +## Testing + +### Unit Tests + +Comprehensive unit test coverage: + +```bash +cd packages/backend +pnpm test src/services/ContractService.test.ts +``` + +Test scenarios: + +- ✅ Transaction proposal creation +- ✅ Signature addition and validation +- ✅ Transaction execution +- ✅ Batch transaction handling +- ✅ Error handling and edge cases +- ✅ Emergency pause functionality + +### Integration Tests + +Full workflow testing with actual Safe: + +```bash +cd packages/backend +pnpm test:integration +``` + +Integration scenarios: + +- Complete signature collection workflow +- Multi-chain deployment testing +- Safe

+ +- **Static data**: Contract addresses, ABI definitions, chain configurations +- **No business logic**: Just data declarations and exports +- **Low risk**: Changes rarely break functionality +- **High maintenance cost**: Tests provide minimal value + +```typescript +// Example: Why not test this? +export const POOL_FACTORY_ADDRESS = '0x742d35Cc6634C0532925a3b8D238a5D2DD8dC5b8' +export const
