2.1 Excluded

Folder test.

3. Findings

In total, 1 issue were reported including:

    • 0 high severity issue.
    • 0 medium issue.
    • 0 low severity issue.
    • 0 note.
    • 1 owner privileges.

3.1 The swapping process completely under the Owner’s control.

Severity: owner privileges.

Description:

The owner can transfer tokens on the Ethereum side and mint them on the BSC side.

However, Owner provides a transaction hash as proof of the user’s swap operation. Therefore anyone can check each swap operation and ensure its correctness.

4. Conclusion

The audited smart contract can be deployed. Pointed issues were fixed.

Since the swapping process completely on the owner’s power, users should understand the risk of an “exit scam”.
