HongKongDAO
In the wab3 new Internet era, companies such as blockchain public chains, games, financial management, social networking, shopping malls, and information services, including community da tokens, are gradually becoming more and more legalized in the global industry. In such a period of great development prospects, the HK service platform platform has clear choices, accurate positioning, and serves all blockchain digital financial platform participants. The platform includes multiple sections, task areas, and forum areas. Advertising area, information area, news area, asset aggregation area, we will use professional technology and meticulous service to introduce huge traffic to the platform, and at the same time we will give most of the wealth created to all workers who have paid for the HK platform

Comments
Comments/Ownership Privileges
- Set the status of Airdrop, and Liquidity pool to true or false, true will result in an airdrop to an 'ad' address which is randomly generated
- The contract has a check for 'excluded from fees' for wallets but no function to implement it.
- The owner can set the buy and sell tax up to 49%. It is recommended to put it under 25%
- The owner can set the marketing pool address
- The owner can transfer any type of tokens from the contract to the marketing pool address including the native ones
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.
low Issues

#1 Issue
Local variables shadowing (shadowing-local)
L66
L225
L66
L225
Rename the local variables that shadow another component.
Pending
#2 Issue
Missing Zero Address Validation (missing-zero-check)
L52
Check that the address is not zero.
Pending
#3 Issue
Uninitialized state variables (uninitialized-state)
L10
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.
Pending
#4 Issue
Contract doesnât import npm packages from source (like OpenZeppelin etc.)
-
We recommend importing all packages from npm directly without flattening the contract. Functions could be modified or can be susceptible to vulnerabilities
Pending
#5 Issue
Floating Pragma
-
The current pragma Solidity directive is â>=0.6.0 <0.9.0". 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
informational Issues
Pending
#1 Issue
Missing error messages
L58
L59
It is recommended to display error messages when the state of the contract reverts. Make sure to add error messages in the "require" statements
