Notes

• New WETH contracts (WETH10, CCIPWETH9Bridge, CCIPWETH10Bridge) are independent and don't require OpenZeppelin ✅
• Existing contracts (CCIPSender, CCIPRouter, CCIPRouterOptimized, MultiSig, Voting) require OpenZeppelin ⚠️
• All documentation is complete ✅
• Implementation tasks are pending decision on solution approach ⏳
