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.


Ownership Privileges
  • Any arbitrary address can claim the stuck tokens and ETH to the stuck token wallet address.
  • The owner can update the marketing wallet address.
  • The marketing wallet will receive ETH when the swapping is completed.

Note - This Audit report consists of a security analysis of the YaYa coinToken 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 YaYa coin team, other contracts associated with the project were not audited by our team. We recommend investors to do their own research before investing.

#1 low Issue
Missing 'require' check.
YaYaCoin.sol
L686-694
Description

Any arbitrary address can claim the stuck tokens and stuck ETH into the stuck tokens wallet address as this can increase unnecessary transactions. It is recommended that there must be a 'require' check where that particular address can only be able to call these functions.
