🚨 Critical Issues Found and Fixed

Issue 1: viaIR Setting ❌ → ✅

Problem: Standard JSON had viaIR: true
Reality: Contract was deployed WITHOUT via-ir
Fix: Changed to viaIR: false

Evidence:

• Deployed bytecode starts with 6080604052... (non-viaIR style)
• viaIR bytecode would start with 60c03462... (different pattern)

Issue 2: EVM Version ⚠️ → ✅

Problem: Forced evmVersion: "london"
Reality: Should let compiler default
Fix: Removed evmVersion field

Issue 3: Constructor Arguments ❌ → ✅

Problem: Using 3 addresses: (router, weth9, feeToken)
Reality: Deployment uses 1 address: (admin/deployer)
Fix: Updated to single address: 0x4A666F96fC8764181194447A7dFdb7d471b301C8

ABI-Encoded: 0x0000000000000000000000004a666f96fc8764181194447a7dfdb7d471b301c8

✅ Corrected Standard JSON

File: docs/CCIPWETH9Bridge_standard_json.json

Settings (corrected):

{
  "settings": {
    "optimizer": {
      "enabled": true,
      "runs": 200
    },
    "viaIR": false,
    "outputSelection": {
      "*": {
        "*": [
          "abi",
          "evm.bytecode",
          "evm.deployedBytecode",
          "evm.bytecode.sourceMap",
          "evm.deployedBytecode.sourceMap"
        ]
      }
    }
  }

🎯 Verification Instructions (Corrected)

Step-by-Step

1. Etherscan URL: https://etherscan.io/address/0x89dd12025bfcd38a168455a44b400e913ed33be2#code

2. Click: "Contract" tab → "Verify and Publish"

3. Select: "Standard JSON Input"

4. Upload: docs/CCIPWETH9Bridge_standard_json.json

5. Compiler Version: v0.8.20+commit.a1b79de6

6. Settings:

   • Optimization: Yes (200 runs)
   • Via IR: NO ← CRITICAL - MUST BE DISABLED
   • EVM Version: Leave default (don't force)

7. Constructor Arguments:

   0x0000000000000000000000004a666f96fc8764181194447a7dfdb7d471b301c8

📊 Before vs After

Setting	Before (Wrong)	After (Correct)
viaIR	true	false
evmVersion	"london"	(removed - default)
Constructor Args	3 addresses	1 address
Bytecode Pattern	60c03462...	6080604052...

---

⚠️ Source Code Note

Important: The source code in the Standard JSON shows a constructor with 3 arguments:

constructor(address _ccipRouter, address _weth9, address _feeToken)

But the actual deployment on Ethereum Mainnet uses only 1 address:

constructor(address _admin)

This suggests:

• The deployed contract might be a different version
• Or deployed through a factory/proxy
• Or the source code needs to match the actual deployment

If verification still fails, the source code itself may need to be updated to have a single-address constructor.
