## Dry Run Summary

### Test Configuration
- **Amount**: 0.1 WETH
- **Source Address**: `0x4A666F96fC8764181194447A7dFdb7d471b301C8`
- **Destination**: Ethereum Mainnet (Selector: 5009297550715157269)
- **Bridge**: `0x89dd12025bfCD38A168455A44B400e913ED33BE2`

---

## Verification Results

### ✅ Passed Checks

1. **ETH Balance**: ✅ Sufficient
   - Available: 999,630,770 ETH
   - Required: ~0.112 ETH (amount + gas)
   - Status: More than sufficient

2. **WETH9 Balance**: ✅ Sufficient
   - Available: 6 WETH
   - Required: 0.1 WETH
   - Status: Sufficient balance available

3. **Bridge Allowance**: ✅ Sufficient
   - Status: Bridge can spend WETH9

### ⚠️ Warnings

1. **CCIP Fee Calculation**: ⚠️ Could not calculate
   - May require LINK tokens for fees
   - Check bridge contract for fee requirements

### ❌ Failed Checks

1. **Destination Configuration**: ❌ **NOT CONFIGURED**
   - **Issue**: Ethereum Mainnet is NOT configured as destination in bridge
   - **Impact**: Bridge transaction will fail
   - **Action Required**: Configure Ethereum Mainnet destination bridge address

## Transaction Simulation

### Would Execute (if destination configured):

1. **Wrap ETH to WETH9**: ⏭️ Skipped (sufficient balance)
2. **Approve Bridge**: ⏭️ Skipped (already approved)
3. **Bridge to Ethereum Mainnet**: ⏳ Would execute
   - Function: `sendCrossChain(uint64,address,uint256)`
   - Destination: Ethereum Mainnet (5009297550715157269)
   - Recipient: `0x4A666F96fC8764181194447A7dFdb7d471b301C8`
   - Amount: 0.1 WETH
   - Estimated Gas: ~300,000

---

## Cost Estimate

- **Amount to Bridge**: 0.1 WETH
- **Gas Costs**: ~0.002 ETH (at 5 gwei)
- **CCIP Fee**: Unknown (may require LINK)
- **Total Cost**: ~0.102 ETH (excluding CCIP fee)

## Critical Issue Found

### ❌ Ethereum Mainnet Destination Not Configured

**Problem**: The bridge contract does not have Ethereum Mainnet configured as a destination.

**Solution**: Configure the destination bridge address:

```bash
# Need to call bridge contract to add destination
# Function: addDestination(uint64 chainSelector, address destinationBridge)
# Parameters:
#   - chainSelector: 5009297550715157269 (Ethereum Mainnet)
#   - destinationBridge: [Ethereum Mainnet bridge address]
```

**Action Required**:
1. Get Ethereum Mainnet bridge address
2. Call `addDestination()` on bridge contract
3. Verify destination is configured
4. Re-run dry run to confirm

---

## Next Steps

1. **Configure Destination**: Add Ethereum Mainnet to bridge destinations
2. **Check CCIP Fee**: Verify if LINK tokens are needed
3. **Re-run Dry Run**: Verify all checks pass
4. **Execute Bridge**: Use `wrap-and-bridge-to-ethereum.sh` when ready

---

## Usage

### Run Dry Run

```bash
# With address
./scripts/dry-run-bridge-to-ethereum.sh 0.1 0xYourAddress

# With private key (will derive address)
./scripts/dry-run-bridge-to-ethereum.sh 0.1 0xYourPrivateKey

# With PRIVATE_KEY in .env
./scripts/dry-run-bridge-to-ethereum.sh 0.1
```

### Execute Bridge (After Fixing Issues)

```bash
./scripts/wrap-and-bridge-to-ethereum.sh 0.1 [private_key]
```
