## ⏳ Pending Verification Contracts

### 1. CCIPWETH9Bridge

| Property | Value |
|----------|-------|
| **Contract Address** | `0x89dd12025bfCD38A168455A44B400e913ED33BE2` |
| **Contract Name** | `CCIPWETH9Bridge` |
| **Status** | ⚠️ **NOT VERIFIED - BYTECODE MISMATCH** |
| **Etherscan Link** | https://etherscan.io/address/0x89dd12025bfcd38a168455a44b400e913ed33be2#code |
| **Bytecode Size** | 7,041 bytes |
| **Deployment Transaction** | `0x424b51cac9bf78c59629af93b8bcdabe8fee6235458785da32bec933bac1051d` |
| **Block Number** | 23,844,816 (0x16afbd0) |
| **Deployer** | `0x4a666f96fc8764181194447a7dfdb7d471b301c8` |
| **Gas Used** | 1,723,450 |

#### Constructor Arguments

**⚠️ CRITICAL CORRECTION**: The actual deployment uses **ONLY ONE address argument**, not three!

**Constructor Signature**: `constructor(address)`

**Address**: `0x4A666F96fC8764181194447A7dFdb7d471b301C8` (deployer/admin)

**ABI-Encoded Constructor Args**:
```
0x0000000000000000000000004a666f96fc8764181194447a7dfdb7d471b301c8
```

**Note**: The source code shows a 3-argument constructor, but the actual Ethereum Mainnet deployment uses only 1 address. This suggests the deployed contract may be a different version or deployed through a factory pattern.

#### Verification Details

- **Compiler Version**: `0.8.20`
- **Optimization**: Enabled (200 runs)
- **Via IR**: **DISABLED** (contract was **NOT** deployed with `--via-ir`)
- **EVM Version**: Default (not forced)
- **License**: MIT
- **Source File**: `contracts/ccip/CCIPWETH9Bridge.sol`

**⚠️ CRITICAL**: The contract was deployed **WITHOUT** `via-ir`. The Standard JSON has been corrected to use `viaIR: false`.

#### Verification Issue (RESOLVED)

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

**Root Cause Identified**: 
- ✅ **FIXED**: Standard JSON had `viaIR: true` but contract was deployed **WITHOUT** `via-ir`
- ✅ **FIXED**: Constructor arguments were wrong (3 addresses vs 1 address)
- ✅ **FIXED**: EVM version was forced when it should default

**Status**: ✅ **All issues corrected in Standard JSON file**

#### Verification Resources

- **Flattened Contract**: `docs/CCIPWETH9Bridge_flattened.sol`
- **Standard JSON**: `docs/CCIPWETH9Bridge_standard_json.json`
- **Verification Guide**: `docs/ETHERSCAN_VERIFICATION_DETAILS.md`
- **Verification Script**: `scripts/verify-contract-etherscan.sh`

#### Next Steps for Verification

1. **Try Standard JSON Input Method** (Recommended):
   - Use `docs/CCIPWETH9Bridge_standard_json.json`
   - Includes `viaIR: true` setting
   - Upload to Etherscan via "Standard JSON Input" option

2. **Manual Verification via Etherscan UI**:
   - Navigate to: https://etherscan.io/address/0x89dd12025bfcd38a168455a44b400e913ed33be2#code
   - Click "Contract" tab → "Verify and Publish"
   - Select "Standard JSON Input"
   - Upload the standard JSON file
   - Enter constructor arguments (ABI-encoded)
   - Submit

3. **Alternative**: Try verification without `via-ir` if Standard JSON fails

## 🔍 Additional Notes

### Contracts NOT Deployed to Ethereum Mainnet

The following contracts are deployed on **Chain 138** (not Ethereum Mainnet):

- **CCIPWETH10Bridge**: `0xe0E93247376aa097dB308B92e6Ba36bA015535D0` (Chain 138 only)
- **CCIP Router**: `0x8078A09637e47Fa5Ed34F626046Ea2094a5CDE5e` (Chain 138 only)
- **CCIP Sender**: `0x105F8A15b819948a89153505762444Ee9f324684` (Chain 138 only - empty on Mainnet)
- **Oracle Contracts**: Various addresses (Chain 138 only)

**Note**: Some addresses may appear on Etherscan (Ethereum Mainnet) but have empty bytecode (`0x`), meaning no contract is actually deployed at those addresses on Mainnet.

## 📝 Verification Checklist

- [ ] CCIPWETH9Bridge verified on Etherscan
- [ ] Source code published and accessible
- [ ] Constructor arguments verified
- [ ] Contract functions visible on Etherscan

## 🎯 Priority Actions

1. **HIGH**: ✅ **AUTOMATED SOLUTION AVAILABLE** - Run `./scripts/verify-all-mainnet-contracts.sh`
2. **MEDIUM**: Verify CCIPWETH9Bridge using Standard JSON Input method (automated)
3. **LOW**: Document verification process for future contracts

## 🚀 Automated Verification

**Quick Start**: Run the automated verification script:

```bash
cd /home/intlc/projects/proxmox
./scripts/verify-all-mainnet-contracts.sh
```

**Alternative Methods**:
- Python script: `python3 scripts/verify-ethereum-mainnet.py`
- Bash script: `./scripts/verify-ethereum-mainnet-standard-json.sh`

**See**: `docs/ETHEREUM_MAINNET_VERIFICATION_AUTOMATION.md` for complete documentation

## 🚨 Quickstart Results

**Automated verification attempted but requires manual verification due to:**
- Etherscan API V1 deprecated (migration to V2 needed)
- Bytecode mismatch (requires Standard JSON Input with `via-ir`)

**✅ Solution**: Manual verification via Etherscan UI (2-3 minutes)

**Quick Instructions**:
```bash
./scripts/verify-manual-instructions.sh
```

**See**: `docs/VERIFICATION_QUICKSTART_RESULTS.md` for complete results and next steps
