LayerZeroReceiver

Summary

The most critical subjects covered in our audit are functional correctness, correct integration with LayerZero, and the security of funds. The general subjects covered are gas efficiency and operational considerations.

The most significant issues uncovered include:

• Ineffective griefing protection, demonstrated how the griefing protection was bypassable under certain conditions.
• Risky sweep mechanism, highlighted the risk that swept fund could be moved without preventing the corresponding message from later being executed.

Both above mentioned issues were resolved accordingly.
‍

In summary, we find that the codebase provides a satisfactory level of security.

It is important to note that security audits are time-boxed and cannot uncover all vulnerabilities. They complement but don't replace other vital measures to secure a project.
