Issues Resolved

Issue 1: Wrong Contract Address ✅ RESOLVED

Problem: Scripts were checking 0x3304b747E565a97ec8AC220b0B6A1f6ffDB837e6 which is a different contract (only 1,311 bytes, missing functions).

Solution: Updated config/address-mapping.json to use correct address 0x89dd12025bfCD38A168455A44B400e913ED33BE2.

Status: ✅ Fixed

Solution: Verified destination is configured and enabled:

• Mainnet selector 5009297550715157269 is in destinations
• Enabled flag is true
• Receiver bridge is set to 0x2A0840e5117683b11682ac46f5CF5621E67269E3

Status: ✅ Verified - Configuration complete

Issue 3: Function Availability ✅ RESOLVED

Problem: Functions appeared to be missing.

Solution: Functions exist in correct contract at 0x89dd12025bfCD38A168455A44B400e913ED33BE2.

Status: ✅ Verified - All functions available

Bridge Usage

Using the Script

cd /home/intlc/projects/proxmox/smom-dbis-138
./scripts/wrap-and-bridge-weth9-to-mainnet.sh <amount_in_eth> <recipient_address> [private_key]

Example:

./scripts/wrap-and-bridge-weth9-to-mainnet.sh 0.1 0x4A666F96fC8764181194447A7dFdb7d471b301C8

Manual Process

1. Wrap ETH to WETH9 (if needed):

cast send 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 \
  "deposit()" \
  --value $(cast --to-wei 0.1 ether) \
  --rpc-url http://192.168.11.211:8545 \
  --private-key $PRIVATE_KEY

2. Approve WETH9:

cast send 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 \
  "approve(address,uint256)" \
  0x89dd12025bfCD38A168455A44B400e913ED33BE2 \
  115792089237316195423570985008687907853269984665640564039457584007913129639935 \
  --rpc-url http://192.168.11.211:8545 \
  --private-key $PRIVATE_KEY

3. Approve Fee Token (if needed):

cast send 0x362E9a45Ef6e554760f9671938235Cbc9b6E80Ed \
  "approve(address,uint256)" \
  0x89dd12025bfCD38A168455A44B400e913ED33BE2 \

  --rpc-url http://192.168.11.211:8545 \
  --private-key $PRIVATE_KEY

4. Bridge to Mainnet:

cast send 0x89dd12025bfCD38A168455A44B400e913ED33BE2 \
  "sendCrossChain(uint64,address,uint256)" \
  5009297550715157269 \
  0x4A666F96fC8764181194447A7dFdb7d471b301C8 \
