- **TransactionMirror Admin**: `0x4A666F96fC8764181194447A7dFdb7d471b301C8` ✅
- Both contracts verified to have correct admin addresses

### 3. Off-Chain Services Created ✅

#### State Anchor Service

- **Purpose**: Collect Chain-138 state proofs and anchor them to MainnetTether
- **Features**:
  - Automatic block monitoring
  - State proof collection
  - Batch anchoring
  - State persistence
  - Error handling

#### Transaction Mirror Service
- **Location**: `scripts/offchain/transaction-mirror-service.js`
- **Purpose**: Mirror Chain-138 transactions to TransactionMirror contract
- **Features**:
  - Automatic transaction monitoring
  - Batch mirroring (up to 100 transactions)
  - State persistence
  - Error handling
  - Configurable intervals

**Usage**:
```bash
# State Anchor Service
node scripts/offchain/state-anchor-service.js

# Transaction Mirror Service
node scripts/offchain/transaction-mirror-service.js
```

**Environment Variables Required**:
- `CHAIN_138_RPC`: Chain-138 RPC endpoint
- `ETHEREUM_MAINNET_RPC`: Ethereum Mainnet RPC
- `MAINNET_TETHER_ADDRESS`: MainnetTether contract address
- `TRANSACTION_MIRROR_ADDRESS`: TransactionMirror contract address
- `PRIVATE_KEY`: Private key for signing transactions

### 4. Monitoring and Alerting Configuration ✅

- **Documentation**: `docs/monitoring/MONITORING_SETUP.md`
- **Coverage**:
  - Contract health monitoring
  - Event monitoring
  - Alerting rules
  - Health check scripts
  - Dashboard recommendations

**Monitoring Tools Recommended**:
- Etherscan Alerts
- OpenZeppelin Defender
- Custom monitoring scripts
- Prometheus + Grafana

### 5. Test Scripts Created ✅

- **Location**: `scripts/testing/test-contracts-mainnet.sh`
- **Purpose**: Test deployed contracts on Ethereum Mainnet
- **Tests**:
  - Admin verification
  - Paused status checks
  - Constant values
  - Function availability

**Usage**:
```bash
./scripts/testing/test-contracts-mainnet.sh
```

**Test Results**: ✅ All basic tests passed

## 🚀 Next Actions (Optional)

### Immediate Actions

1. **Start Off-Chain Services**
   ```bash
   # Start state anchor service
   node scripts/offchain/state-anchor-service.js &
