Scope of Work
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:
- Specification Review: Analyze the provided specifications, source code, and instructions to fully understand the smart contract's size, scope, and functionality.
- Manual Code Examination: Conduct a thorough line-by-line review of the source code to identify potential vulnerabilities and areas for improvement.
- Specification Alignment: Ensure that the code accurately implements the provided specifications and intended functionalities.
- Test Coverage Assessment: Evaluate the extent and effectiveness of test cases in covering the codebase, identifying any gaps in testing.
- Symbolic Execution: Analyze the smart contract to determine how various inputs affect execution paths, identifying potential edge cases and vulnerabilities.
- Best Practices Evaluation: Assess the smart contracts against established industry and academic best practices to enhance efficiency, maintainability, and security.
- Actionable Recommendations: Provide detailed, specific, and actionable steps to secure and optimize the smart contracts.
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.
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.
Ownership Privileges
- The owner can set a pool fee.
- The owner can set a pool wallet address.
- The owner can add/remove the wallet from the blacklist.
Note - This Audit report consists of a security analysis of the BattleKoin smart contract. This analysis did not include functional testing (or unit testing) of the contract’s logic. Moreover, we only audited one token contract for the BattleKoin team. Other contracts associated with the project were not audited by our team. We recommend investors do their own research before investing.

Findings and Audit result
medium Issues | 2 findings
Pending
#1 medium Issue
The owner can set fees more than 25%.
The owner can set the total buy and sell fees of more than 100% in the contract which is not recommended. The fees in the contract should not be more than 25% so that the user not lose his token values.
Pending
#2 medium Issue
Missing 'require' check. (Potential honeypot).
The owner can set any arbitrary address to the pool wallet address, including zero address as this can lead to a potential honeypot if the owner has set the address to a contract address that cannot receive ETH. It is recommended that the address cannot be set to a contract address that cannot receive ETH to avoid these circumstances.
low Issues | 4 findings

#1 low Issue
Floating pragma solidity version.
Adding the constant version of solidity is recommended, as this prevents the unintentional deployment of a contract with an outdated compiler that contains unresolved bugs.
Pending
#2 low Issue
Missing events arithmetic.
Adding the constant version of solidity is recommended, as this prevents the unintentional deployment of a contract with an outdated compiler that contains unresolved bugs.
Pending
#3 low Issue
Local variables shadowing (shadowing-local).
Rename the local variables that shadow another component.
Pending
#4 low Issue
Missing Zero Address Validation (missing-zero-check).
Check that the address is not zero.
