## Technical Fixes

### Hex to Decimal Conversion

**Problem**: Scripts were comparing hex values directly with decimal values.

**Fix**: Added proper conversion:
```bash
if echo "$VALUE" | grep -q "^0x"; then
    VALUE_DEC=$(cast --to-dec "$VALUE" 2>/dev/null || echo "0")
else
    VALUE_DEC="$VALUE"
fi
```

### Zero Address Detection

**Problem**: Multiple zero address formats not detected.

**Fix**: Enhanced detection:
```bash
if [ -n "$ADDRESS" ] && ! echo "$ADDRESS" | grep -qE "^0x0+$" && [ "$ADDRESS" != "0x0000000000000000000000000000000000000000" ]; then
    # Valid address
fi
```

### Balance Comparisons

**Problem**: Comparing hex strings with decimal numbers.

**Fix**: Convert to decimal first, then compare:
```bash
WETH9_BAL_DEC=$(cast --to-dec "$WETH9_BAL" 2>/dev/null || echo "0")
if [ "$WETH9_BAL_DEC" = "0" ] || (( $(echo "$WETH9_BAL_DEC < $AMOUNT_WEI" | bc -l) )); then
    # Need to wrap
fi
```

**Usage**:
```bash
# Configure all (Ethereum Mainnet skipped if not provided)
./scripts/configure-all-bridge-destinations.sh [private_key]

# Configure all including Ethereum Mainnet
./scripts/configure-all-bridge-destinations.sh [private_key] [weth9_eth_mainnet] [weth10_eth_mainnet]
```

### 2. dry-run-bridge-to-ethereum.sh

**Improvements**:
- ✅ Fixed hex/decimal conversion
- ✅ Fixed balance parsing
- ✅ Fixed allowance parsing
- ✅ Better error messages
- ✅ References fix script in output

### 3. check-bridge-config.sh

**Improvements**:

- ✅ Clearer output format
- ✅ Summary statistics

### 4. fix-bridge-errors.sh

**Improvements**:
- ✅ Better destination verification
- ✅ Improved parsing
- ✅ Better error messages

---

## Verification

### Script Syntax ✅

All scripts have been syntax-checked:
```bash
✅ check-bridge-config.sh
✅ configure-all-bridge-destinations.sh
✅ fix-bridge-errors.sh
✅ dry-run-bridge-to-ethereum.sh
```

### Parsing Logic ✅

All parsing issues fixed:
- ✅ Hex to decimal conversion
- ✅ Zero address detection
- ✅ Balance comparisons
- ✅ Allowance checks

---

## Usage Guide

### Step 1: Check Current Status

```bash
./scripts/check-bridge-config.sh
```

Shows which destinations are configured.

### Step 2: Configure All Destinations

```bash
# Configure all known destinations (except Ethereum Mainnet)
./scripts/configure-all-bridge-destinations.sh [private_key]

# Or with Ethereum Mainnet addresses
./scripts/configure-all-bridge-destinations.sh [private_key] [weth9_eth_mainnet] [weth10_eth_mainnet]
```

### Step 3: Configure Ethereum Mainnet (if needed)

```bash
./scripts/fix-bridge-errors.sh [private_key] [ethereum_mainnet_bridge_address]
```

### Step 4: Verify

```bash
# Check configuration
./scripts/check-bridge-config.sh

# Run dry run
./scripts/dry-run-bridge-to-ethereum.sh 0.1 [address]
```
