Smart Contract Audit Report
CYBERCATS is a new BEP-20 token on the Binance Smart Chain.
For this audit, we reviewed the project team's BEP20Token contract at 0x1064497597e9295e27a24435dab15cf67daf3558 on the Binance Smart Chain Mainnet.
Informational findings were identified and the team may want to review them.
Date: November 3rd, 2022.
Finding #1 - BEP20Token - InformationalDescription: The internal _burn() and _burnFrom() functions are never called in the contract.
Recommendation: These functions could be removed to reduce contract size and deployment costs.
Finding #2 - BEP20Token - InformationalDescription: Although the SafeMath library is utilized, the contract is deployed with Solidity v0.8.7 which has built-in overflow/underflow checks.
Recommendation: SafeMath could be safely removed to reduce contract size, deployment costs, and gas costs on all transactions that utilize it.
- The total supply of the token is set to 200 million $CCAT [200,000,000].
- No mint or burn functions are accessible, though the circulating supply can be decreased by sending tokens to the 0x..dead address.
- At the time of writing this report, 100% of the total supply belongs to the deployer.
- There are no fees associated with transferring tokens.
- As the contract is deployed with Solidity v0.8.7, it is safe from any possible overflows/underflows.
- The contract complies with the BEP-20 token standard.
|Arbitrary Jump/Storage Write||N/A||PASS|
|Centralization of Control||The team currently owns 100% of the total supply.||PASS|
|Delegate Call to Untrusted Contract||N/A||PASS|
|Dependence on Predictable Variables||N/A||PASS|
|Improper Authorization Scheme||N/A||PASS|
|Outdated Compiler Version||N/A||PASS|
|Unused Code||The internal _burn() and _burnFrom() functions are never called in the contract.||PASS|
|Overall Contract Safety||PASS|

What is a Solidity Audit?
Typically, a smart contract audit is a comprehensive review process designed to discover logical errors, security vulnerabilities, and optimization opportunities within code. A Solidity Audit takes this a step further by verifying economic logic to ensure the stability of smart contracts and highlighting privileged functionality to create a report that is easy to understand for developers and community members alike.
How Do I Interpret the Findings?
Each of our Findings will be labeled with a Severity level. We always recommend the team resolve High, Medium, and Low severity findings prior to deploying the code to the mainnet. Here is a breakdown on what each Severity level means for the project:
- High severity indicates that the issue puts a large number of users' funds at risk and has a high probability of exploitation, or the smart contract contains serious logical issues which can prevent the code from operating as intended.
- Medium severity issues are those which place at least some users' funds at risk and has a medium to high probability of exploitation.
- Low severity issues have a relatively minor risk association; these issues have a low probability of occurring or may have a minimal impact.
- Informational issues pose no immediate risk, but inform the project team of opportunities for gas optimizations and following smart contract security best practices.
