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 burn function within the contract.

Ownership is not renounced

Contract can be manipulated by owner functions.

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:

  1. Specification Review: Analyze the provided specifications, source code, and instructions to fully understand the smart contract's size, scope, and functionality.
  2. Manual Code Examination: Conduct a thorough line-by-line review of the source code to identify potential vulnerabilities and areas for improvement.
  3. Specification Alignment: Ensure that the code accurately implements the provided specifications and intended functionalities.
  4. Test Coverage Assessment: Evaluate the extent and effectiveness of test cases in covering the codebase, identifying any gaps in testing.
  5. Symbolic Execution: Analyze the smart contract to determine how various inputs affect execution paths, identifying potential edge cases and vulnerabilities.
  6. Best Practices Evaluation: Assess the smart contracts against established industry and academic best practices to enhance efficiency, maintainability, and security.
  7. 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.

Findings and Audit result

low Issues | 4 findings

Pending

#1 low Issue
Local variables shadowing (shadowing-local)
MemeCard.sol
L333
L356
Description

Rename the local variables that shadow another component.

Pending

#2 low Issue
Missing Zero Address Validation (missing-zero-check)
MemeCard.sol
L274
Description

Check that the address is not zero.

Pending

#3 low Issue
Floating Pragma
MemeCard.sol
-
Description

The current pragma Solidity directive is “^0.8.4". Contracts should be deployed with the same compiler version and flags that they have been tested thoroughly. Locking the pragma helps to ensure that contracts do not accidentally get deployed using other versions.

Pending

#4 low Issue
Contract doesn’t import npm packages from source (like OpenZeppelin etc.)
MemeCard.sol
-
Description

We recommend importing all packages from npm directly without flattening the contract. Functions could be modified or can be susceptible to vulnerabilities
