Top Dog
TopDog was formed in early August 2022. The core team consists of several people from around the world for diversification. Each member is highly experienced in their own field including, development, marketing, programming aspiring new technology, and growing strong communities in the crypto space. TopDog is deployed on the Binance Smart Chain (BSC) and plans to move into centralized exchanges. The strategically chosen tokenomics incorporates automated core token functions.
Owner privileges
Comments
Ownership Privileges:
The contract can have multiple authorities because there are three modifiers named "onlyOwner", "authorized", "onlyToken".
There is no maximum limit on the number of wallets the owner can authorize.
The onlyToken modifier is misleading because there is no check if the value of the "_token" set at the time of deployment is actually a contract address or a wallet address.
The owner can set max wallet percent to a minimum of 1 token, transfer ownership, and authorize/unauthorize new accounts to perform certain actions like:
- Enable/Disable greed, Trigger manual buyback, and clearBuybackMultiplier
- Set auto buy-back settings to manipulate the cap, amount, period, and multiplier to any value because there are no limits or ranges.
- Set max buy limit percent but not zero. Although, it can be set to any value greater than zero.
- Set max sell limit percent but not zero. Although, it can be set to any value greater than zero.
- Exempt wallets from dividends, fees, and maximum transactions.
- Set buy/sell fees, and fee receiver address.
- Set swap back settings and target liquidity to any amount, even zero, and to the max value of uint
- Send the contract balance manually to the marketing fee receiver address, which is again controlled by the "authorized" wallets.
The Contract/Wallet address that is set under the "onlyToken" modifier can do the following changes:
-
Set distribution criteria to any period. For example, the minimum period can be the same as the maximum or they can be both zero, and they can be changed anytime.
-
Set shares for the shareholder. For example, the person controlling the "_token" address can allocate as many tokens as a dividend to any arbitrary account/wallet
-
Deposit tokens into the contract and call the process function
-
Claim dividend for any share holder.
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
Pending
#1 Issue
Missing Events Arithmetic (events-maths)
All
Emit an event for critical parameter changes. There are no events for any critical parameter changes done by authorities or the owner in the contract.
Pending
#2 Issue
Missing Zero Address Validation (missing-zero-check)
L138,266,346
L888
Check that the address is not zero.
Pending
#3 Issue
Floating Pragma
-
The current pragma Solidity directive is â^0.8.17". Contracts should be deployed with the same compiler version and flag that they have been tested thoroughly. Locking the pragma helps to ensure that contracts do not accidentally get deployed using other versions
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
