- We recommend you to remove SafeMath and use raw mathematical operations
- Liquidity will be added to the owner. Be aware of this because the owner can take out the liquidity anytime
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)
- 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.

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.
"Owner can regain ownership after transferring it with following steps: Call lock function to set _previousOwner to the own address Call unlock function to get ownership back Transfer/renounce ownership Call unlock function to get ownership back Make sure to set the _previousOwnership back to address zero after using the unlock function"
Fee's can be set over 100% and lock user funds
All fee's can be set without any limitation. If the fees are set over it by the owner, the user funds can be locked. We recommend you to implement a restriction to the set fee functions to make sure that the variable cannot be set over max 25%. TaxFee + liquidityFee + devFee must not be over 100%. In this case the transferAmount will be 0.
Lock user funds with maxTxAmount
The owner is able to set the maxTxAmount variable to 0. When this happen nobody is able to buy/sell any tokens anymore.
Local variables shadowing (shadowing-local)
Rename the local variables that shadow another component.
Missing Events Arithmetic (events-maths)
Emit an event for critical parameter changes.
Missing Zero Address Validation (missing-zero-check)
Check that the address is not zero.
State variable visibility
Provide the visibility to the state variable
Functions that are not used (dead-code)
Remove unused functions.
Public function that could be declared external (external-function)
Use the `external` attribute for functions never called from the contract.
