# WETH Unwrap Script Instructions

## Quick Start

**This script will help you get your WETH back if the wrapping transaction failed.**

### Step 1: Check Prerequisites

```bash
# Install required packages if not already installed
pip install web3 eth-account python-dotenv
```

### Step 2: Verify Environment Setup

Ensure your `.env` file contains:
```env
MAINNET_RPC_URL=https://arb1.arbitrum.io/rpc
MAIN_WALLET_PRIVATE_KEY=0x_your_private_key_here
```

### Step 3: Run the Script

```bash
python unwrap_weth.py
```

## What the Script Does

1. **Checks your balances** - Shows current WETH and ETH balance
2. **Checks failed transaction** - Verifies status of your previous wrap attempt
3. **Offers unwrap options**:
   - Unwrap all WETH
   - Unwrap specific amount
4. **Executes with high gas** - Uses 3x gas price to ensure success
5. **Monitors transaction** - Waits up to 10 minutes for confirmation

## Important Features

✅ **Safe Transaction Management**
- Uses higher gas limits (150k gas)
- 3x gas price multiplier for faster processing
- 10-minute timeout for network congestion
- Confirmation before executing

✅ **Error Handling**
- Checks if previous transaction actually succeeded
- Handles network errors gracefully
- Detailed logging to `unwrap_weth.log`

✅ **Transaction Monitoring**
- Provides Arbiscan links for tracking
- Shows before/after balances
- Clear success/failure reporting

## Expected Output

```
=== WETH Unwrap Script ===
✅ Connected to Chain ID: 42161

Current WETH Balance: 0.016483 WETH

2. Unwrap specific amount
3. Exit

Sending WETH unwrap transaction...
Transaction sent: 0xabcdef123...

✅ WETH unwrap successful!
```

## Troubleshooting

### If script fails with connection error:
- Check your RPC URL in .env file
- Try a different RPC endpoint:
```env
MAINNET_RPC_URL=https://arbitrum-one.public.blastapi.io
```

### If transaction still fails:
- Network may be congested, try again later
- Check your ETH balance for gas fees
- The script automatically uses high gas prices

### If you see "No WETH balance":
- Your previous transaction may have succeeded
- Check Arbiscan for the transaction hash
- Your ETH should already be back

## Safety Notes

⚠️ **Always verify:**
- Transaction details before confirming
- Final balances after operation
- Transaction on Arbiscan

✅ **Script protections:**
- Will never exceed your WETH balance
- Asks for confirmation before any transaction
- Uses reasonable gas limits
- Logs all operations

## After Success

Once the unwrap completes:
1. Your WETH will be converted back to native ETH
2. You can check the transaction on Arbiscan
3. Your ETH balance will increase by the unwrapped amount
4. Your WETH balance will decrease to 0 (if unwrapping all)

## Support

If you encounter issues:
1. Check the `unwrap_weth.log` file for detailed error messages
2. Verify your .env file configuration
3. Ensure you have sufficient ETH for gas fees
4. Try running the script again (it will re-check transaction status)
