Contract address 0xbE2e74309760B6B8e2D62bad4fC17B86ffb833a7
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.
Contract cannot be locked Owner can't lock any user funds.
Token cannot be burned There is no burn function within the contract.
Ownership is not renounced Contract can be manipulated by owner functions.

Comment

  • SafeMath library is unnecessary because safemath functionality is implemented above floating pragma version 0.8.4 by default. We recommend you to remove the "SafeMath" library and use raw mathematical operations instead
  • addresses that are excluded by the owner cannot call the deliver function
  • The liquidty will be added to the owner. Be aware of it because the owner can drain out the liquidity pool.

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 specification 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 | Local variables shadowing (shadowing-local)
Severity Location Status
Low LiquidityGeneratorToken.sol : 1075, 1440 Pending
Description

Rename the local variables that shadow another component.

Comment

Recommendation: Change to "owner_"

#2 | Missing Events Arithmetic (events-maths)
Severity Location Status
Low LiquidityGeneratorToken.sol : 1242-1248, 1250-1259 Pending
Description

Emit an event for critical parameter changes.

#4 | Tautology or contradiction (tautology)
Severity Location Status
Low LiquidityGeneratorToken.sol : 972-1043, 972-1043, 972-1043 Pending
Description

Fix the incorrect comparison by changing the value type or the comparison.

Comment

"taxFeeBps_", "liquidityFeeBps_" and "charityFeeBps_" cannot be lower than 0. The first three require statements are unnecessary because the range of uint16 is from 0 to 2^16 - 1

#5 | State variable visibility is missing
Severity Location Status
Low LiquidityGeneratorToken.sol : 953 Pending
Description

The state variable visibility is missing: - "inSwapAndLiquify"

#2 | Functions that are not used (dead-code)
Severity Location Status
Informational LiquidityGeneratorToken.sol : 494-496, 504-510, 523-529, 537-548, 583-585, 593-602, 556-558, 566-575, 441-451, 469-474, 610-630, 106-108, 376-385, 336-338, 402-411, 207-213, 249-254, 261-266, 232-242, 220-225 Pending
Description

Remove unused functions.
