**Deployment Command**:
```bash
forge script script/DeployMainnetTether.s.sol \
  --rpc-url "$ETHEREUM_MAINNET_RPC" \
  --private-key $PRIVATE_KEY \
  --broadcast \
  --verify \
  --via-ir \
  -vvvv
```

### TransactionMirror

**Purpose**: Mirror Chain-138 transactions to Ethereum Mainnet for Etherscan visibility

**Status**: ✅ **DEPLOYED**

- **Address**: `0x4CF42c4F1dBa748601b8938be3E7ABD732E87cE9`
- **Admin**: `0x4A666F96fC8764181194447A7dFdb7d471b301C8` (EOA)
- **Explorer**: https://etherscan.io/address/0x4CF42c4F1dBa748601b8938be3E7ABD732E87cE9
- **Verification**: ⚠️ Auto-verification failed (contract is deployed, may need manual verification)

**Features**:
- Transaction mirroring with indexed events
- Batch mirroring support (up to 100 transactions)
- Admin-controlled pause functionality
- Gas usage tracking
- Success/failure status

**Deployment Command**:
```bash
forge script script/DeployTransactionMirror.s.sol \
  --rpc-url "$ETHEREUM_MAINNET_RPC" \
  --private-key $PRIVATE_KEY \
  --broadcast \
  --verify \
  --via-ir \
  -vvvv
```

## 📝 Environment Variables

Both addresses have been added to `.env`:

```bash
MAINNET_TETHER_ADDRESS=0x15DF1D5BFDD8Aa4b380445D4e3E9B38d34283619
TRANSACTION_MIRROR_ADDRESS=0x4CF42c4F1dBa748601b8938be3E7ABD732E87cE9
```

---

## 🔧 Technical Details

### Compilation
- Both contracts required `--via-ir` flag due to "Stack too deep" compiler limitations

- Optimizer: 200 runs

### Gas Costs
- **MainnetTether**: ~1,200,000 gas
- **TransactionMirror**: ~1,175,958 gas

### RPC Configuration
- **Format**: `https://PROJECT_ID:PROJECT_SECRET@mainnet.infura.io/v3/PROJECT_ID`
- **Authentication**: Basic auth with project secret
- **Status**: ✅ Working

## 🔗 Next Steps

1. **Verify TransactionMirror on Etherscan** (if auto-verification failed)
   ```bash
   forge verify-contract \
     --chain-id 1 \
     --num-of-optimizations 200 \
     --via-ir \
     0x4CF42c4F1dBa748601b8938be3E7ABD732E87cE9 \
     contracts/mirror/TransactionMirror.sol:TransactionMirror \
     $ETHERSCAN_API_KEY \
     --constructor-args $(cast abi-encode "constructor(address)" 0x4A666F96fC8764181194447A7dFdb7d471b301C8)
   ```

2. **Set Up Off-Chain Services**
   - State proof anchoring service for MainnetTether
   - Transaction mirroring service for TransactionMirror

3. **Configure Access Control**
   - Review admin addresses
   - Consider multi-sig upgrade path if needed
   - Set up monitoring for admin actions

4. **Testing**
   - Test state proof anchoring
   - Test transaction mirroring
   - Verify event indexing on Etherscan
