Security Assessments
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
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:
- 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 only once.
- The owner can set the max tx amount.
- The owner can set the presale contract address.
- The owner can exclude the address from max tx.
- The owner can set the buy/sell fees at no more than the maximum.
- The owner can set the fee receiver address.
- The owner can set a swap threshold amount.
- The owner set an automated market pair address.
- The owner can whitelist the address.
- The owner can extract ETH and stuck tokens.
- The owner can force a swap.
Note - This Audit report consists of a security analysis of the ZAP 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 ZAP 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
medium Issues | 3 findings
Pending
#1 medium Issue
Transfer of tokens without enabling trade.
The trading needs to be enabled by the owner in order for regular users to transfer tokens. On the contrary, the owner can authorize addresses manually and those addresses will be able to trade tokens. This functionality can be exploited in the following way, For example, there is a presale and the wallets used for the presale can be authorized by the owner. All the tokens obtained can be consolidated into a final wallet address and facilitate trading and selling of the acquired tokens, the last wallet address can be authorized.
Pending
#2 medium Issue
Missing 'require' check. (Potential honeypot)
The owner can set any arbitrary address to the feeReceiver address excluding zero address as this can lead to a potential honeypot if the owner has set the address to a contract address that cannot receive ETH. It is recommended that the address cannot be set to a contract address that cannot receive ETH to avoid these circumstances.
Pending
#3 medium Issue
The owner can lock funds.
The owner can set any arbitrary amount in the max transaction and max wallet amount, including zero, which is not recommended as this can lock the transfer function for an unlimited period of time. There must be a threshold amount so that the amount cannot be set to zero. Add a 'require' check in the contract so that the amount cannot be less than at least 0.1% of the total supply of tokens.

#1 low 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.
Pending
#2 low Issue
Missing events arithmetic.
Emit an event for critical changes.
Pending
#3 low Issue
Local variables shadowing (shadowing-local)
Rename the local variables that shadow another component.
