# Bridge Testing Guide
**Date**: $(date)
**Purpose**: Complete guide for testing cross-chain bridge transfers
---
## ✅ Verification Complete
All bridge configurations have been verified:
- ✅ WETH9 Bridge: All 6 destinations configured
- ✅ WETH10 Bridge: All 6 destinations configured
- ✅ Fee calculation: Working
- ✅ Bridge contracts: Deployed and operational
---
## 🧪 Testing Options
### Option 1: Automated Verification (Recommended)
Run the verification script to check all configurations:
```bash
cd /home/intlc/projects/proxmox
bash scripts/verify-bridge-configuration.sh
```
This verifies:
- All destination chains are configured
- Fee calculation is working
- Bridge contracts are accessible
- Token balances are readable
---
### Option 2: Manual Transfer Testing
To test actual transfers, use the test script:
```bash
# Test WETH9 transfer to BSC
bash scripts/test-bridge-transfers.sh bsc 0.01 weth9
# Test WETH10 transfer to Polygon
bash scripts/test-bridge-transfers.sh polygon 0.01 weth10
```
**Requirements**:
- Sufficient ETH balance for wrapping
- Sufficient balance for gas fees
- LINK tokens (if using LINK for fees) or native ETH
**Process**:
1. Wraps ETH to WETH9/WETH10
2. Approves bridge to spend tokens
3. Calculates CCIP fee
4. Sends cross-chain transfer
5. Returns transaction hash for monitoring
---
### Option 3: Test All Destinations
To test transfers to all 6 destination chains:
```bash
#!/bin/bash
# Test all destinations
CHAINS=("bsc" "polygon" "avalanche" "base" "arbitrum" "optimism")
AMOUNT="0.01"
for chain in "${CHAINS[@]}"; do
echo "Testing WETH9 transfer to $chain..."
bash scripts/test-bridge-transfers.sh "$chain" "$AMOUNT" weth9
sleep 10 # Wait between transfers
done
for chain in "${CHAINS[@]}"; do
echo "Testing WETH10 transfer to $chain..."
bash scripts/test-bridge-transfers.sh "$chain" "$AMOUNT" weth10
sleep 10 # Wait between transfers
done
```
**Note**: This will cost gas fees for each transfer. Start with one chain to verify functionality.

## 🔍 Monitoring Transfers
After initiating a transfer:
1. **Check Transaction on Source Chain**:
```bash
cast tx <transaction_hash> --rpc-url http://192.168.11.250:8545
```
2. **Check Events**:
```bash
cast logs --address <bridge_address> "CrossChainTransferInitiated" --rpc-url http://192.168.11.250:8545
```
3. **Wait for CCIP Processing**: Typically 1-5 minutes
4. **Check Destination Chain**: Verify receipt on destination chain explorer
---
## ⚠️ Important Notes
1. **Gas Costs**: Each transfer costs gas. Budget accordingly.
2. **Test Amounts**: Start with small amounts (0.01 ETH) for testing.
3. **Processing Time**: CCIP transfers take 1-5 minutes to process.
4. **Fee Requirements**: Ensure sufficient balance for fees (LINK or native ETH).
5. **Destination Verification**: Verify transfers on destination chain explorers.
