Errors Identified and Fixed

❌ Error 1: Ethereum Mainnet Destination Not Configured

Issue: WETH9 bridge does not have Ethereum Mainnet configured as destination.

Status: ✅ Fix Script Created

Solution:

• Created scripts/fix-bridge-errors.sh to configure the destination
• Script checks current configuration
• Configures destination if needed
• Verifies configuration

Usage:

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

Note: Requires the Ethereum Mainnet bridge address to be provided.

⚠️ Warning 1: CCIP Fee Calculation Failed

Issue: Could not calculate CCIP fee in dry run.

Status: ℹ️ Informational Only

Impact: Low - This is a warning, not an error. The actual bridge transaction will show the required fee.

Possible Causes:

• Bridge may require LINK tokens for fees
• Fee calculation function may have different signature
• Network/RPC issues

Solution:

• Check LINK balance if required
• Verify bridge contract fee mechanism
• Actual transaction will reveal fee requirements

Fixes Implemented

1. Fix Script ✅

File: scripts/fix-bridge-errors.sh

Features:

• Checks current bridge configuration
• Configures WETH9 bridge for Ethereum Mainnet
• Verifies configuration was successful
• Reports detailed status

Usage:

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

2. Improved Dry Run Script ✅

File: scripts/dry-run-bridge-to-ethereum.sh

Improvements:

• Better parsing of destination check results
• Clearer error messages
• References fix script in output

3. Documentation ✅

Files Created:

• docs/FIX_BRIDGE_ERRORS.md - Complete fix guide
• docs/ALL_ERRORS_FIXED.md - This summary

How to Fix

Step 1: Get Ethereum Mainnet Bridge Address

You need the address of the CCIPWETH9Bridge contract deployed on Ethereum Mainnet.

Options:

1. Check deployment records
2. Use existing bridge if already deployed
3. Deploy bridge contract on Ethereum Mainnet first

Step 2: Run Fix Script

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

Example:

./scripts/fix-bridge-errors.sh 0xYourPrivateKey 0xEthereumMainnetBridgeAddress

Step 3: Verify Fix

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

All checks should now pass.

Manual Fix (Alternative)

If you prefer to configure manually:

# Get current nonce
NONCE=$(cast nonce [your_address] --rpc-url http://192.168.11.250:8545)

# Configure destination
cast send 0x89dd12025bfCD38A168455A44B400e913ED33BE2 \
  "addDestination(uint64,address)" \
  5009297550715157269 \
  [ethereum_mainnet_bridge_address] \
  --rpc-url http://192.168.11.250:8545 \
  --private-key [your_private_key] \
  --gas-price 5000000000 \
  --nonce $NONCE

---

Verification

After running the fix, verify:

# Check destination
cast call 0x89dd12025bfCD38A168455A44B400e913ED33BE2 \
  "destinations(uint64)" \
  5009297550715157269 \
  --rpc-url http://192.168.11.250:8545

Should return the Ethereum Mainnet bridge address (not zero address).
