Contract address 0x5f8F4EC4A2eB5dfAc587b045B3509AdC799AdB88
No critical 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's not possible to mint new tokens.
Contract owner cannot blacklist addresses. It's not possible to lock user funds by blacklisting addresses.
Contract owner cannot set fees above 25% The fees can be a maximum of 25%. The contract can therefore not be locked.
Token transfer can be locked Owner can lock user funds with owner functions.
Token can be burned There is a function to burn tokens in the contract.
Ownership is not renounced Contract can be manipulated by owner functions.

Comment

  • Owner can
    • burn with "burnTokens" function from contract adderss itself in L1241
    • blacklist anyone in the contract
  • Transfer function will blacklisted every contract if it is trying to sell tokens

Audit Scope

This audit covered the following files listed below with a SHA-1 Hash. The above token Team provided us with the files that needs to be tested.

We will verify the following claims:
  • Correct implementation of Token standard
  • Deployer cannot mint any new tokens
  • Deployer cannot burn or lock user funds
  • Deployer cannot pause the contract
  • Overall checkup (Smart Contract Security)
The auditing process follows a routine series of steps:
  • Review of the specifications, sources, and instructions provided to SolidProof to make sure we understand the size, scope, and functionality of the smart contract.
  • Manual review of code, which is the process of reading source code line-by-line in an attempt to identify potential vulnerabilities.
  • Comparison to specification, which is the process of checking whether the code does what the specifications, sources, and instructions provided to SolidProof describe.
  • Test coverage analysis, which is the process of determining whether the test cases are actually covering the code and how much code is exercised when we run those test cases.
  • Symbolic execution, which is analysing a program to determine what inputs causes each part of a program to execute.
  • Best practices review, which is a review of the smart contracts to improve efficiency, effectiveness, clarify, maintainability, security, and control based on the established industry and academic practices, recommendations, and research.
  • Specific, itemized, actionable recommendations to help you take steps to secure your smart contracts.

A file with a different Hash has been modified, intentionally or otherwise, after the security review. A different Hash could be (but not necessarily) an indication of a changed condition or potential vulnerability that was not within the scope of this review.

Audit details

Throughout the review process, care was taken to evaluate the repository for security-related issues, code quality, and adherence to speciïŹcation and best practices. To do so, reviewed line-by-line by our team of expert pentesters and smart contract developers, documenting any issues as there were discovered.

Risk represents the probability that a certain source-threat will exploit vulnerability, and the impact of that event on the organization or system. Risk Level is computed based on CVSS version 3.0.

#1 | Functions that are not used (dead-code)
Severity Location Status
Informational LUCKYGENIE.sol : 354-356, 364-370, 383-389, 397-408, 443-445, 453-462, 416-418, 426-435, 329-334, 470-490, 745-747, 1124-1131, 685-694, 645-647, 711-720, 516-522, 558-563, 570-575, 541-551, 529-534 Pending
Description

Remove unused functions.

#4 | Unnecessary library
Severity Location Status
Informational LUCKYGENIE.sol : - Pending
Description

Contact doesn't need to implement "SafeMath" library because it is already implemented by default above pragma version 0.8.x. If you're going to fix it and remove it from the contract, make sure to change every "SafeMath" mathematical operations with raw mathematical operations

#1 | State variables that could be declared constant (constable-states)
Severity Location Status
Optimization LUCKYGENIE.sol : 1163, 1162, 1161, 1155, 1157, 1144, 1156, 1158, 1160 Pending
Description

Add the `constant` attributes to state variables that never change.

#2 | Public function that could be declared external (external-function)
Severity Location Status
Optimization LUCKYGENIE.sol : 804-806, 812-815, 899-901, 906-908, 913-915, 920-922, 927-929 Pending
Description

Use the `external` attribute for functions never called from the contract.
