2.1 Owner Privileges



Owner Privileges.


50 Billion Enduracoin will be pre-minted to the owner’s wallet.

2.2 A few minor observation



Minor Observation.


  1. The getPendingChangeRequest() is a view function, so it does not require onlyApprovers modifier.
  1. The owner must be the final approver in voting for transferapprovetransferFromincreaseAllowance. If the owner votes earlier the change request can’t be approved and all other approvers should vote against it to be able to create a new request. It creates an opportunity for a frontrunning attack by a malicious approver, where he can flip his vote just before the owner’s vote (so the owner will not be the last approver).

3. Security Practices

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 to ensure the contract’s operability and prevent any issues that are not directly related to the code of this smart contract.

6. CLO Coin Buyback & Burn Strategy

Callisto Security directly boosts CLO’s value for each smart contract audit performed by allocating a portion of the audit’s revenue for a CLO coin buyback and burn.

For this audit of Enduracoin Token:

  • Buyback Funds: 660 USD.

These purchased coins were subsequently burned, reducing CLO’s total supply and enhancing its value for all holders.

The buyback and burn strategy directly ties Callisto Security’s success to CLO’s value, adding another layer of utility for our community. For more details, see our GitHub.
