## 🔗 Next Steps

1. **Verify Contracts on Etherscan**
   - Check contract verification status
   - Verify source code matches deployed bytecode
   - Verify admin address is Defender address

2. **Configure Defender**
   - Set up Defender relayer for automated operations
   - Configure Defender policies and rate limits
   - Set up Defender monitoring and alerts

3. **Set Up Off-Chain Services**
   - State proof anchoring service for MainnetTether
   - Transaction mirroring service for TransactionMirror
   - Configure services to use Defender for transactions

4. **Test Contracts**
   - Test state proof anchoring (via Defender)
   - Test transaction mirroring (via Defender)
   - Test batch operations
   - Test pause/unpause functionality (via Defender)

## 📊 Contract Information

### MainnetTether
- **Purpose**: Anchor Chain-138 state proofs to Ethereum Mainnet
- **Admin**: Defender address (from `DEFENDER_ADMIN`)
- **Functions**:
  - `anchorStateProof()` - Anchor a state proof (requires Defender admin)
  - `getStateProof()` - Retrieve a state proof
  - `isAnchored()` - Check if block is anchored
  - `pause()` / `unpause()` - Emergency controls (requires Defender admin)

### TransactionMirror
- **Purpose**: Mirror Chain-138 transactions to Ethereum Mainnet for Etherscan visibility
- **Admin**: Defender address (from `DEFENDER_ADMIN`)
- **Functions**:
  - `mirrorTransaction()` - Mirror a single transaction (requires Defender admin)
  - `mirrorBatchTransactions()` - Mirror multiple transactions (requires Defender admin)
  - `getTransaction()` - Retrieve mirrored transaction
  - `isMirrored()` - Check if transaction is mirrored
  - `pause()` / `unpause()` - Emergency controls (requires Defender admin)

## ⚠️ Important Notes

1. **Defender Admin**: All admin functions require Defender address
2. **Gas Costs**:
   - MainnetTether deployment: ~1,200,000 gas
   - TransactionMirror deployment: ~1,000,000 gas
3. **Verification**: Contracts should be automatically verified on Etherscan
4. **Off-Chain Services**: Required for full functionality
5. **Defender Setup**: Configure Defender relayer for automated operations

---

## 🔧 Defender Integration

### Setting Up Defender Relayer

1. **Create Defender Relayer**
   - Go to OpenZeppelin Defender
   - Create a new relayer
   - Copy the relayer address

2. **Configure Environment**
   ```bash
   DEFENDER_ADMIN=<defender_relayer_address>
   ```

3. **Deploy Contracts**
   - Contracts will use Defender address as admin
   - All admin functions can be executed via Defender

4. **Set Up Defender Actions**
   - Create Defender actions for `anchorStateProof()`
   - Create Defender actions for `mirrorTransaction()`
   - Configure Defender policies and rate limits
