Owner privileges
Comments
Ownership/Authority Privileges:
The authority other than the owner known as Verifier will be decided at the time of deployment and it can only be changed when the owner and the verifier itself vote. But even after the voting it will be upon the owner's discretion to set the verifier.
The verifier address has no privileges but the verifier's vote can decide whether the owner will be able to make transfers or not.
The owner has the following privileges:
- Enable/Disable antiDump and antiBot
- Set antiDump interval and amount to any arbitrary value.
- Include/Exclude wallets from fees and excluded wallets will also not be affected by the max transaction
- Set the max transaction amount to any arbitrary value including zero to lock user funds that are not excluded from the fees.
- Set fee wallet, and Enable/Disable fees
- Start and Stop Trading to lock user funds
- Set AMM pair address
- Recover ETH and other tokens from the contract.
We recommend investors/users do their own research before investing
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)
- 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 speciïŹcation 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.
