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 cannot be burned
There is no burning within the contract without any allowances
Ownership is not renounced
The owner retains significant control, which could potentially be used to modify key contract parameters.
Contract is not upgradeable
The contract does not use proxy patterns or other mechanisms to allow future upgrades. Its behavior is locked in its current state.
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
- There are no ownership privileges in this contract.
Note - This Audit report consists of a security analysis of the BeatCoin 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 BeatCoin 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
low Issues | 2 findings
Pending
#1 low Issue
Old compiler version
The pragma directive on line 7 specifies pragma solidity 0.5.16;, locking the contract to an obsolete compiler version. This version lacks critical security features introduced in later releases, most notably the built-in arithmetic overflow and underflow protection added in Solidity 0.8.0. While the contract attempts to mitigate this by using the SafeMath library, this approach is error-prone and adds unnecessary gas overhead. Additionally, version 0.5.16 misses years of security patches, gas optimizations, improved error handling with custom errors, and better compiler warnings that help developers catch potential bugs during development.
Pending
#2 low Issue
Local variables shadowing (shadowing-local)
Rename the local variables that shadow another component.

Unnecessary Ownable Inheritance
The BEATCOIN contract on line 345 inherits from Ownable, which provides ownership management capabilities including the onlyOwner modifier, transferOwnership(), and renounceOwnership() functions. However, upon inspection of the entire contract, there are no active functions that utilize the onlyOwner modifier to restrict access. The only function that would have required owner privileges was mint() on line 503, but it has been commented out. This means the contract deploys with ownership infrastructure that serves no practical purpose—the owner address exists but has no special powers over the token. This results in unnecessary bytecode deployment costs, increased contract complexity, and potential confusion for users who may assume the owner has elevated privileges when they do not.
