2.1 Owner privileges

Severity: owner privileges.


The function Swap() allow users to swap CVN to CVNX tokens. But CVNX tokens initially belongs to the owner wallet, so if owner transfer tokens to another wallet swap will not work.

3. Security practices

  •  Open-source contact.
  •  The contract should pass a bug bounty after the completion of the security audit.
  •  Public testing.
  •  Multisig owner account.
  •  Standard ERC20-related issues. IMPLEMENTED. It is known that every contract can potentially receive unintended ERC20-token deposit without the ability to reject it even if the contract is not intended to receive or hold tokens. As the result it is recommended to implement a function that will allow to extract any arbitrary number of tokens from the contract.

4. Conclusion

The audited smart contract can be deployed. No security issues were found during the audit.

It is recommended to adhere to the security practices described in pt. 3 of this report in order to ensure the operability of the contract and prevent any issues which are not directly related to the code of this smart-contract.
