🚀 How to Use the Bridge

Quick Start

cd /home/intlc/projects/proxmox/smom-dbis-138

# Bridge 0.1 ETH worth of WETH9 to Mainnet
./scripts/wrap-and-bridge-weth9-to-mainnet.sh 0.1 0xYourMainnetAddress

Step-by-Step Process

1. Wrap ETH to WETH9 (if needed):

   • Script handles this automatically
   • Or manually: cast send 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 "deposit()" --value <amount>

2. Approve WETH9 (if needed):

   • Script handles this automatically
   • Already approved: max uint256 ✅

3. Approve Fee Token (if needed):

   • Bridge uses LINK at 0x362E9a45Ef6e554760f9671938235Cbc9b6E80Ed
   • User needs LINK balance and approval

4. Bridge to Mainnet:

   • Script calls sendCrossChain(5009297550715157269, recipient, amount)
   • Wait 1-5 minutes for CCIP confirmation
   • WETH9 appears on Mainnet

⚠️ Important Notes

Fee Token Address

The bridge uses LINK at 0x362E9a45Ef6e554760f9671938235Cbc9b6E80Ed (not the deployed LINK at 0xb7721dD53A8c629d9f1Ba31a5819AFe250002b03).

Action Required: Users need LINK at the bridge's fee token address for fees.

WETH9 Balance

Current wallet has 0 WETH9. Users need to:

1. Have ETH balance
2. Wrap ETH to WETH9 (script handles this)
3. Then bridge

calculateFee() Reverts

The calculateFee() function currently reverts, but this doesn't prevent bridging. The fee is calculated internally during sendCrossChain().
