TapDaDoge Info
TapDaDoge promises an easily accessible, endlessly entertaining and rewarding experience. The player (You) takes control of their NFT Characters to jump over obstacles and in the process, earns various types of Points, which can be used in exchange for more goodies. The game is meant to have simple and intuitive mechanics that are tough to master but highly rewarding. Now, let’s get acquainted with our main cast of Characters (NFTs). Below are a limited sample of our Furry Friends, also known as “Doges”. You’ll notice that they have each been assigned a designation (e.g. “Unique”, “Legendary”, et cetera.).

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.

Findings and Audit result
medium Issues | 1 findings
Pending
#1 medium Issue
Missing Fee Validation in Constructor
The contract contains the functionality where the constructor accepts _buyFee and _sellFee parameters without any validation, allowing potential deployment with excessively high fees. While the setBuySellFee function properly limits fees to a maximum of 20%, this restriction is absent during contract initialization, creating a security inconsistency.
low Issues | 2 findings
Pending
#1 low Issue
Missing zero or dead address check.
It is recommended to check that the address cannot be zero or dead address.
Pending
#2 low Issue
Missing events arithmetic
It is recommended to emit all the critical parameter changes.
informational Issues | 1 findings

#1 informational 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.
