Summary and Final Words
No crucial issues found
The contract does not contain issues of high or medium criticality. This means that no known vulnerabilities were found in the source code.
Contract owner cannot mint
It is not possible to mint new tokens.
Contract owner cannot blacklist addresses.
It is not possible to lock user funds by blacklisting addresses.
Contract owner cannot set high fees
The fees, if applicable, can be a maximum of 25% or lower. The contract can therefore not be locked. Please take a look in the comment section for more details.
Contract cannot be locked
Owner cannot lock any user funds.
Token can be burned
There is a function to burn tokens in the contract.
Ownership is not renounced
Contract can be manipulated by owner functions.
Scope of Work
Final Words
The following provides a concise summary of the audit report, accompanied by insightful comments from the auditor. This overview captures the key findings and observations, offering valuable context and clarity.
The owner can:
- Withdraw the tokens from the SwapHelper contract
- Approve any token address for a certain amount
- Exempt fee receiver address and Remove accounts from fees mapping
- Set Developing wallets
- Set buy back and hold amount/address (also with decimals)
- Buy back and burn with/without decimals
- Set WBNB Token Pair
- Set WBNB/BUSD Pair
- Grant permission to other accounts for the following roles: "Admin", "Financial", "Controller", and "Operator"
- The wallets with admin permission can; withdraw tokens from the contract and approve other tokens.
- Due to the Authorized contract, there will be an admin in the contract even after renouncing the ownership because there can be multiple authorities controlling the contract. Moreover, only the wallets with 'admin' permission can revoke the role
Renouncing ownership will not affect the admin privileges of the wallets and there can be 'n' number of wallets that can be authorized for admin and other privileges because there is no protection from it. Thus, there is no maximum number of wallets that can have multiple authorizations over the contract.

Findings and Audit result
low Issues | 7 findings
Pending
#1 low Issue
Missing Zero Address Validation (missing-zero-check)
Check that the address is not zero.
Pending
#2 low Issue
State variables shadowing (shadowing-state)
Remove the state variable shadowing.
Pending
#3 low Issue
Missing Events
Emit events for critical parameter changes. There are no events in the contract
Pending
#4 low Issue
Floating Pragma
The current pragma Solidity directive is “^0.8.15". 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
#5 low Issue
Contract doesn’t 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
#6 low Issue
Admin can drain tokens
Owner/Wallets with admin permission can withdraw the native tokens from the contract
Pending
#7 low Issue
Owner can drain tokens
Owner can also withdraw the native tokens from the contract
optimization Issues | 3 findings
Pending
#1 optimization Issue
Public function that could be declared external (external-function)
Use the `external` attribute for functions never called from the contract.
Pending
#2 optimization Issue
Public function that could be declared external (external-function)
Use the `external` attribute for functions never called from the contract.
Pending
#3 optimization Issue
Public function that could be declared external (external-function)
Use the `external` attribute for functions never called from the contract.

This audit encompasses the evaluation of the files listed below, each verified with a SHA-1 Hash. The team referenced above has provided the necessary files for assessment.
The auditing process consists of the following systematic steps:
A file with a different Hash has been intentionally or otherwise modified after the security review. A different Hash may indicate a changed condition or potential vulnerability that was not within the scope of this review.
