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
- The Minter role can mint new tokens that are not more than the max supply.
- The DEFAULT_ADMIN_ROLE can update the max supply value to any arbitrary value after the initial deployment.
Note - This Audit report consists of a security analysis of the Haifu 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 Haifu 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
high Issues | 1 findings
Resolved
#1 high Issue
Unrestricted Max Supply Modification by Admin Role
The current implementation contains a significant centralization vulnerability where the DEFAULT_ADMIN_ROLE can arbitrarily increase the maximum token supply through the setMaxSupply() function without any constraints or governance mechanisms. This function only validates that the new maximum supply is not below the current total supply, but places no upper bounds or rate limits on increases. The unrestricted nature of this functionality allows a single admin to potentially inflate the token supply indefinitely, which could severely devalue existing tokens held by investors.
informational Issues | 2 findings
Resolved
#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.
Resolved
#2 informational Issue
Missing events arithmetic
It is recommended to emit all the critical parameter changes.
