|
|
|
|
**Date**: $(date)
|
|
**Contract**: CCIPWETH9Bridge (`0x89dd12025bfCD38A168455A44B400e913ED33BE2`)
|
|
**Status**: ⚠️ **BYTECODE MISMATCH - TROUBLESHOOTING**
|
|
|
|
---
|
|
|
|
## 🔍 Current Situation
|
|
|
|
### Verification Attempts
|
|
|
|
1. **First Attempt**: Compiler version mismatch (0.8.19 vs 0.8.20)
|
|
- ✅ **Fixed**: Updated instructions to select 0.8.20
|
|
|
|
2. **Second Attempt**: Invalid "compiler" field in Standard JSON
|
|
- ✅ **Fixed**: Removed invalid field
|
|
|
|
3. **Current Issue**: Bytecode mismatch
|
|
- ⚠️ **Status**: Standard JSON compiles but bytecode doesn't match deployed contract
|
|
- **Error**: "Unable to find matching Contract Bytecode and ABI"
|
|

## 🎯 Next Steps for Verification
|
|
|
|
### Option 1: Try Generated Standard JSON
|
|
|
|
Use the newly generated Standard JSON file:
|
|
|
|
1. **Go to Etherscan**:
|
|
https://etherscan.io/address/0x89dd12025bfcd38a168455a44b400e913ed33be2#code
|
|
|
|
2. **Click "Contract" tab → "Verify and Publish"**
|
|
|
|
3. **Select "Standard JSON Input"**
|
|
|
|
4. **Upload**: `docs/CCIPWETH9Bridge_standard_json_generated.json`
|
|
|
|
5. **Select Compiler Version**: `v0.8.20+commit.a1b79de6`
|
|
|
|
6. **Enable "Via IR"**: Yes
|
|
|
|
7. **Optimization**: Yes (200 runs)
|
|
|
|
8. **Enter Constructor Arguments**:
|
|
```
|
|
0x00000000000000000000000080226fc0ee2b096224eeac085bb9a8cba1146f7d000000000000000000000000c02aaa39b223fe8d0a0e5c4f27ead9083c756cc2000000000000000000000000514910771af9ca656af840dff83e8264ecf986ca
|
|
```
|
|
|
|
9. **Submit**
|
|
|
|
### Option 2: Verify Source Code Matches
|
|
|
|
The bytecode mismatch suggests the source code might not exactly match what was deployed. Check:
|
|
|
|
1. **Compare deployed bytecode** with what the Standard JSON compiles to
|
|
2. **Verify source code** hasn't changed since deployment
|
|
3. **Check deployment transaction** for exact compiler settings
|
|
|
|
### Option 3: Use Sourcify (Alternative)
|
|
|
|
Sourcify is an alternative verification service:
|
|
|
|
1. Go to: https://sourcify.dev/
|
|
2. Upload contract metadata
|
|
3. Submit for verification

## 🔧 Troubleshooting Bytecode Mismatch
|
|
|
|
### Possible Causes
|
|
|
|
1. **Source Code Changed**: Contract source modified after deployment
|
|
2. **Compiler Settings**: Subtle difference in compiler settings
|
|
3. **Import Resolution**: Different import resolution during deployment
|
|
4. **Metadata**: Metadata differences affecting bytecode
|
|
|
|
### Diagnostic Commands
|
|
|
|
```bash
|
|
# Get deployed bytecode
|
|
cast code 0x89dd12025bfCD38A168455A44B400e913ED33BE2 --rpc-url $ETHEREUM_MAINNET_RPC > deployed.bytecode
|
|
|
|
# Compare with compiled bytecode from Standard JSON
|
|
# (Would need to compile Standard JSON locally and compare)
|
|
```

## 💡 Recommendations
|
|
|
|
1. **Try Generated Standard JSON First**: Use the newly generated file
|
|
2. **Verify Exact Settings**: Ensure all compiler settings match deployment exactly
|
|
3. **Check Deployment Transaction**: Review the actual deployment transaction for clues
|
|
4. **Consider Manual Verification**: Sometimes manual verification via UI works when automated fails
|
|
5. **Alternative Services**: Try Sourcify if Etherscan continues to fail
