0x0Factory
Welcome to the future of privacy and security on the Ethereum network. 0x0 is a revolutionary platform that offers a comprehensive suite of tools to protect users from scams and ensure the security of their transactions. The platform includes an AI-powered smart contract auditor and a privacy mixer. Additionally, 0x0 is working on a privacy DEX, an all-in-one hub for writing custom smart contracts and an AI bot that can detect and front-run suspicious transactions to prevent becoming the victim of a scam.
Owner privileges

Ownership Privileges
The manager address has the following privileges in the contract
- Set manager, treasury, and token addresses.
- Set token token fee, and standard fee but within a safe range.
- The change of the token address
- Set token fee discount to any arbitrary value
It is also recommended to add a pause function in case there is a security breach or something similar.
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.
