Summary and Final Words

No crucial issues found

The contract does not contain issues of high or medium criticality. This means that no known vulnerabilities were found in the source code.

Contract owner cannot mint

It is not possible to mint new tokens.

Contract owner can blacklist addresses

It is possible to lock user funds by blacklisting addresses.

Contract owner can set high fees

Contract owner is able to set fees above 25%. Very high fees can also prevent token transfer.

Token transfer can be locked

Owner can lock user funds with owner functions.

Token cannot be burned

There is no burning within the contract without any allowances

Ownership is not renounced

The owner retains significant control, which could potentially be used to modify key contract parameters.

Scope of Work

This audit encompasses the evaluation of the files listed below, each verified with a SHA-1 Hash. The team referenced above has provided the necessary files for assessment.

The auditing process consists of the following systematic steps:

  1. Specification Review: Analyze the provided specifications, source code, and instructions to fully understand the smart contract's size, scope, and functionality.
  2. Manual Code Examination: Conduct a thorough line-by-line review of the source code to identify potential vulnerabilities and areas for improvement.
  3. Specification Alignment: Ensure that the code accurately implements the provided specifications and intended functionalities.
  4. Test Coverage Assessment: Evaluate the extent and effectiveness of test cases in covering the codebase, identifying any gaps in testing.
  5. Symbolic Execution: Analyze the smart contract to determine how various inputs affect execution paths, identifying potential edge cases and vulnerabilities.
  6. Best Practices Evaluation: Assess the smart contracts against established industry and academic best practices to enhance efficiency, maintainability, and security.
  7. Actionable Recommendations: Provide detailed, specific, and actionable steps to secure and optimize the smart contracts.

A file with a different Hash has been intentionally or otherwise modified after the security review. A different Hash may indicate a changed condition or potential vulnerability that was not within the scope of this review.

Note - This Audit report consists of a security analysis of the Critter Token smart contract. This analysis did not include functional testing (or unit testing) of the contract’s logic. Moreover, we only audited one token contract for the Critter team, other contracts associated with the project were not audited by our team. We recommend investors to do their own research before investing.

Findings and Audit result

medium Issues | 3 findings

Pending

#1 medium Issue
The owner can lock tokens
Critter.sol
L621-628
Description

The owner can set any arbitrary value in the max transaction and max wallet amount, which can lock the tokens for an indefinite period of time which is not recommended. Add a certain threshold where the value cannot be less than that number.

Pending

#2 medium Issue
The owner can set fees upto 100%.
Critter.sol
L519-525
Description

The owner can set buy and sell fees up to 100% which is not recommended. No fees should be more than 25% present in the contract.

Pending

#3 medium Issue
The owner can blacklist wallets.
Critter.sol
L556-569
Description

The owner can blacklist wallets from transferring of tokens for an indefinite period of time which is not recommended. There must be a certain lock period where the user can be locked for a certain period of time.

Missing Zero Address Validation (missing-zero-check)
Critter.sol
L528
L834
Description

Check that the address is not zero.

Pending

#3 low Issue
Floating pragma solidity version.
Critter.sol
L2
Description

Adding the constant version of solidity is recommended, as this prevents the unintentional deployment of a contract with an outdated compiler that contains unresolved bugs.

Pending

#4 low Issue
Remove safemath library.
Critter.sol
L16-49
Description

compiler version above 0.8.0 has the ability to control arithmetic overflow/underflow, It is recommended to remove the unwanted code in order to avoid high gas fees.
