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:

# 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

# 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)

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