# Etherscan Verification - FIXED Settings
|
|
|
|
**Error**: "Unable to find matching Contract Bytecode and ABI"
|
|
**Solution**: Use **Via IR: YES**
|

|
## ✅ CORRECT Verification Settings
|
|
|
|
### Form Fields
|
|
|
|
| Field | Value |
|
|
|-------|-------|
|
|
| **Contract Address** | `0x89dd12025bfcd38a168455a44b400e913ed33be2` |
|
|
| **Compiler Type** | `SINGLE FILE / CONCATENATED METHOD` |
|
|
| **Compiler Version** | `v0.8.20+commit.a1b79de6` |
|
|
| **License** | `MIT License (MIT)` |
|
|
| **Optimization** | `Yes` (200 runs) |
|
|
| **Via IR** | ✅ **YES** ← **CRITICAL!** |
|
|
|
|

|
|
|
|
## 🔑 Key Fix
|
|
|
|
**The contract was deployed with `--via-ir` flag**, so verification **MUST** also use **Via IR: YES**.
|
|
|
|
The bytecode mismatch occurred because:
|
|
- ❌ Verification attempted with: Via IR: **No**
|
|
- ✅ Deployment used: Via IR: **Yes**
|
