✅ Post-Deployment Checklist

• Contracts deployed with Defender admin
• Addresses verified on Etherscan
• .env file updated with addresses
• Defender admin address configured
• Defender relayer configured for automated operations
• 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 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

   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
