## ⚠️ Verification Issue

**Error**: `Fail - Unable to verify. Compiled contract deployment bytecode does NOT match the transaction deployment bytecode.`

**Root Cause**: The contract was deployed with `via-ir` enabled, but Etherscan's verification may not support this compiler setting, or the bytecode doesn't match due to:
- Different compiler settings during deployment vs verification
- Source code changes since deployment
- Etherscan's verification system limitations with `via-ir`

## 🔧 Verification Command

Use this command to attempt verification:

```bash
cd /home/intlc/projects/smom-dbis-138
source .env

forge verify-contract \
  0x89dd12025bfCD38A168455A44B400e913ED33BE2 \
  contracts/ccip/CCIPWETH9Bridge.sol:CCIPWETH9Bridge \
  --chain-id 1 \
  --etherscan-api-key "$ETHERSCAN_API_KEY" \
  --constructor-args 0x00000000000000000000000080226fc0ee2b096224eeac085bb9a8cba1146f7d000000000000000000000000c02aaa39b223fe8d0a0e5c4f27ead9083c756cc2000000000000000000000000514910771af9ca656af840dff83e8264ecf986ca \
  --compiler-version 0.8.20 \
  --num-of-optimizations 200 \
  --watch
```

## 🎯 Next Steps

### Option 1: Manual Verification via Etherscan UI

1. Go to: https://etherscan.io/address/0x89dd12025bfcd38a168455a44b400e913ed33be2#code
2. Click "Contract" tab → "Verify and Publish"
3. Select:
   - **Compiler Type**: Solidity (Single file) or Standard JSON Input
   - **Compiler Version**: `0.8.20`
   - **Open Source License**: MIT
   - **Optimization**: Yes (200 runs)
   - **Via IR**: Try both with and without
4. Paste the contract source code
5. Enter constructor arguments (ABI-encoded)
6. Submit for verification

### Option 2: Standard JSON Input

If single-file verification fails, use Standard JSON Input:

```bash
cd /home/intlc/projects/smom-dbis-138
forge build --force
# Then use the standard JSON from out/CCIPWETH9Bridge.sol/CCIPWETH9Bridge.json
```

### Option 3: Check Deployment Settings

Verify the exact compiler settings used during deployment:
- Check if `via-ir` was actually used
- Verify optimizer runs (200)
- Confirm Solidity version (0.8.20)

## 📊 Deployment Information

From broadcast file (`broadcast/DeployCCIPWETH9Bridge.s.sol/1/run-latest.json`):

- **Deployment Transaction**: `0x424b51cac9bf78c59629af93b8bcdabe8fee6235458785da32bec933bac1051d`
- **Block Number**: `0x16afbd0` (23,844,816)
- **Deployer**: `0x4a666f96fc8764181194447a7dfdb7d471b301c8`
- **Gas Used**: `0x1a5c3a` (1,723,450)

**Note**: The broadcast file shows a different contract address (`0x3304b747e565a97ec8ac220b0b6a1f6ffdb837e6`), which suggests this may be a different deployment or the contract at `0x89dd12025bfCD38A168455A44B400e913ED33BE2` was deployed separately.

## 🔍 Troubleshooting

1. **Bytecode Mismatch**: 
   - Ensure source code matches exactly what was deployed
   - Check if any imports or dependencies have changed
   - Verify compiler settings match deployment

2. **Via-IR Issue**:
   - Try verification without `via-ir` flag
   - Etherscan may not support `via-ir` verification
   - Consider recompiling without `via-ir` for verification

3. **Constructor Arguments**:
   - Double-check all addresses are correct
   - Ensure proper ABI encoding

## ✅ Verification Script

A verification script has been created at:
`/home/intlc/projects/proxmox/scripts/verify-contract-etherscan.sh`

Run it with:
```bash
cd /home/intlc/projects/proxmox
./scripts/verify-contract-etherscan.sh
```
