## 🔐 Admin Configuration

### Admin Address
- **Type**: EOA (Externally Owned Account)
- **Default**: Deployer address (`0x4A666F96fC8764181194447A7dFdb7d471b301C8`)
- **Custom**: Set `TETHER_ADMIN`/`MIRROR_ADMIN` in `.env` for different admin

### Security Notes

⚠️ **Important**: EOA admin provides single-point-of-failure security model.

**Recommendations**:
- Use hardware wallet for admin private key
- Store private key securely (never commit to git)
- Consider upgrading to multisig (Gnosis Safe) for production
- Regularly review admin access
- Have recovery procedures documented

## ✅ Post-Deployment Checklist

- [x] Contracts deployed with EOA admin
- [ ] Addresses verified on Etherscan
- [ ] `.env` file updated with addresses
- [ ] Admin private key secured
- [ ] Off-chain services configured:
  - [ ] State proof anchoring service (for MainnetTether)
  - [ ] Transaction mirroring service (for TransactionMirror)

---

## 🔗 Next Steps

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

2. **Secure Admin Access**
   - Ensure admin private key is stored securely
   - Use hardware wallet if possible
   - Document recovery procedures

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

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

5. **Consider Upgrading to Multisig** (Optional for Production)
   - Deploy Gnosis Safe wallet
   - Transfer admin to Safe address
   - Configure Safe with multiple signers

## 📊 Contract Information

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

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

## ⚠️ Important Notes

1. **EOA Admin**: Single private key controls all admin functions
2. **Security**: Use hardware wallet and secure key storage
3. **Gas Costs**:
   - MainnetTether deployment: ~1,200,000 gas
   - TransactionMirror deployment: ~1,000,000 gas
4. **Verification**: Contracts should be automatically verified on Etherscan
5. **Off-Chain Services**: Required for full functionality
6. **Upgrade Path**: Can transfer admin to multisig later if needed

---

## 🔄 Upgrading to Multisig (Optional)

If you want to upgrade to multisig later:

1. **Deploy Gnosis Safe**
   - Go to https://safe.global/
   - Create Safe wallet
   - Add signers and set threshold

2. **Transfer Admin**
   ```bash
   # Transfer MainnetTether admin
   cast send <MAINNET_TETHER_ADDRESS> \
     "setAdmin(address)" \
     <SAFE_ADDRESS> \
     --rpc-url $ETHEREUM_MAINNET_RPC \
     --private-key $CURRENT_ADMIN_PRIVATE_KEY

   # Transfer TransactionMirror admin
   cast send <TRANSACTION_MIRROR_ADDRESS> \
     "setAdmin(address)" \
     <SAFE_ADDRESS> \
     --rpc-url $ETHEREUM_MAINNET_RPC \
     --private-key $CURRENT_ADMIN_PRIVATE_KEY
   ```
