AlienFi

AlienFi is a decentralized exchange (DEX) built on the Arbitrum Chain that provides fast, secure, and low-cost tokens trading with total transparency and full control over your funds.

Owner privileges
Comments
The owner is able to Mint new tokens without any limitations. Beware of this.
Note for Investors: We only Audited a simple token and Governance contract for AlienFi with only a few functions. However, If the project has other contracts (for example, a Presale contract, etc), and they were not provided to us in the audit scope then we cannot comment on its security. Hence, we are not responsible for it in any way.
We recommend investors/users to 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.

#2 Issue
Floating Pragma
-
The current pragma Solidity directive is â^0.6.12". Contracts should be deployed with the same compiler version and flags that they have been tested thoroughly. Locking the pragma helps to ensure that contracts do not accidentally get deployed using other versions
Pending
#3 Issue
Old Compiler Version
-
The contract uses an old compiler version (^0.6.12) and we don't recommend using it because old versions tend to have known vulnerabilities that may get exploited in the future.
