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.

There is no burning within the contract without any allowances

Ownership is renounced

The contract does not include owner functions that allow post-deployment modifications.

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
  • The ownership of the token is renounced. Hence, the owner cannot change any settings in the contract.

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

Findings and Audit result

medium Issues | 1 findings

Pending

#1 medium Issue
Liquidity is added to externally owned address.
Nextar.sol
L409
Description

The contract's liquidity is automatically added to the 'owner' address, which is not recommended because, in an extreme scenario, this can be used to drain liquidity from the contract. It is recommended that the liquidity of the contract should be added to contract address or dead address to avoid these circumstances.

low Issues | 2 findings

Pending

#1 low Issue
Local variables shadowing (shadowing-local)
Nextar.sol
L243
L279
Description

Rename the local variables that shadow another component.
