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 enable trading but cannot disable it.
- The owner can remove limits.
- The owner can update the total buy and sell fee to 100%.
- The owner can update the max transaction and max wallet amount to an arbitrary value, including zero, which may result in the contract being a honeypot
- Include/Exclude wallets from max tx limits and fees
- Set Marketing and Team wallet address
- Enable/Disable swap and liquify
Note - This Audit report consists of a security analysis of the MAROSCA Token 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 MAROSCA team. Our team did not audit other contracts associated with the project. We recommend investors do their own research before investing.

#1 high Issue
The owner can set Arbitrary Fee
The owner can set fees up to 100% or more, which is not recommended because if done so, then all the user funds will be lost during buying/selling.
medium Issues | 2 findings
Pending
#1 medium Issue
The owner can lock contract (Potential Honeypot)
The owner can set the max transaction and max wallet limit to a very low number or even zero, which will result in the contract becoming a honeypot because no user will be able to transfer their funds.
Pending
#2 medium Issue
Liquidity is Transferred to the owner address
The liquidity is automatically credited to the owner's address, which is not recommended as it may cause the owner to drain all the liquidity

Pending
#2 low Issue
Missing Events Arithmetic
Emit an event for critical parameter changes.
Pending
#3 low Issue
