Contract Name: CCIPWETH9Bridge
Network: Ethereum Mainnet

📋 Verification Form Fields

Compiler Type

Select: Solidity (Single file) or Standard JSON Input

Recommendation: Start with Solidity (Single file). If that fails due to imports, use Standard JSON Input.

---

Compiler Version

Select: 0.8.20

Note:

• The contract source specifies pragma solidity ^0.8.19;
• The foundry.toml specifies solc_version = "0.8.20"
• The contract was deployed with version 0.8.20
• Use 0.8.20 for verification

---

Open Source License Type

Select: MIT License (MIT)

Source: The contract file contains:

// SPDX-License-Identifier: MIT

---

🔧 Additional Settings

Optimization

• Enabled: ✅ Yes
• Runs: 200

Via IR

• Enabled: ⚠️ Try both Yes and No
  • The contract was deployed with --via-ir flag
  • Etherscan may not support via-ir verification
  • If verification fails with via-ir enabled, try without it

EVM Version

• Version: london (default for Solidity 0.8.20)

🎯 Step-by-Step Verification

Method 1: Solidity (Single file)

1. Go to: https://etherscan.io/address/0x89dd12025bfcd38a168455a44b400e913ed33be2#code
2. Click "Contract" tab → "Verify and Publish"
3. Fill in the form:
   • Compiler Type: Solidity (Single file)
   • Compiler Version: 0.8.20
   • License: MIT License (MIT)
   • Optimization: Yes (200 runs)
   • Via IR: Try No first, then Yes if it fails
4. Paste the contract source code from contracts/ccip/CCIPWETH9Bridge.sol
5. Important: You'll need to flatten the contract (include all imports)
6. Enter constructor arguments (ABI-encoded)
7. Click "Verify and Publish"

Method 2: Standard JSON Input

If single-file verification fails:

1. Use the same form but select "Standard JSON Input"
2. Generate Standard JSON:

   cd /home/intlc/projects/smom-dbis-138
   forge build --force
   # The Standard JSON will be in the build artifacts
   

3. Upload the Standard JSON file
4. Enter constructor arguments
5. Submit

⚠️ Common Issues

Issue: Bytecode Mismatch

Solution:

• Try verification without via-ir first
• Ensure all imports are included (flatten the contract)
• Verify compiler version matches exactly (0.8.20)

Issue: Missing Imports

Solution:

• Use "Flatten Source Code" feature in Etherscan
• Or use Standard JSON Input method

Issue: Constructor Arguments Error

Solution:

• Ensure addresses are in correct format (lowercase or checksummed)
• Verify ABI encoding is correct
