System Overview
Vapor Wallet is a token with the following contracts:
VPRToken — is a simple ERC-20 token that mints the entire initial supply to a deployer. Additional minting is not allowed.
It has the following attributes:
Name: Vapor Token
Symbol: VPR
Decimals: 18
Total supply: 1 billion tokens.
Privileged roles
No privileged roles.
Executive Summary
Documentation quality
The total Documentation Quality score is 10 out of 10.
Functional requirements are present:
Tokenomic description is provided.
Technical description is provided:
NatSpec is sufficient.
Code quality
The total Code Quality score is 10 out of 10
The development environment is configured.
Test coverage
Code coverage of the project is 0% .
Tests are not provided (according to our methodology, tests are not mandatory for projects smaller than 250 lines of codes).
Security score
Upon auditing, the code was found to contain 0 critical, 0 high, 0 medium, and 0 low severity issues, leading to a security score of 10 out of 10.
All identified issues are detailed in the “Findings” section of this report.
Summary
The comprehensive audit of the customer's smart contract yields an overall score of 10. This score reflects the combined evaluation of documentation, code quality, test coverage, and security aspects of the project.
Risks
All tokens are minted to a single address. The secureness of the supply depends on the secureness of key storage.
Findings
No vulnerabilities were foundAppendix 1. Severity Definitions
When auditing smart contracts Hacken is using a risk-based approach that considers the potential impact of any vulnerabilities and the likelihood of them being exploited. The matrix of impact and likelihood is a commonly used tool in risk management to help assess and prioritize risks.
The impact of a vulnerability refers to the potential harm that could result if it were to be exploited. For smart contracts, this could include the loss of funds or assets, unauthorized access or control, or reputational damage.
The likelihood of a vulnerability being exploited is determined by considering the likelihood of an attack occurring, the level of skill or resources required to exploit the vulnerability, and the presence of any mitigating controls that could reduce the likelihood of exploitation.
Severity | Description |
|---|---|
Critical | Critical vulnerabilities are usually straightforward to exploit and can lead to the loss of user funds or contract state manipulation. |
High | High vulnerabilities are usually harder to exploit, requiring specific conditions, or have a more limited scope, but can still lead to the loss of user funds or contract state manipulation. |
Medium | Medium vulnerabilities are usually limited to state manipulations and, in most cases, cannot lead to asset loss. Contradictions and requirements violations. Major deviations from best practices are also in this category. |
Low | Major deviations from best practices or major Gas inefficiency. These issues will not have a significant impact on code execution, do not affect security score but can affect code quality score. |
Severity
- Critical
Description
- Critical vulnerabilities are usually straightforward to exploit and can lead to the loss of user funds or contract state manipulation.
Severity
- High
Description
- High vulnerabilities are usually harder to exploit, requiring specific conditions, or have a more limited scope, but can still lead to the loss of user funds or contract state manipulation.
Severity
- Medium
Description
- Medium vulnerabilities are usually limited to state manipulations and, in most cases, cannot lead to asset loss. Contradictions and requirements violations. Major deviations from best practices are also in this category.
Severity
- Low
Description
- Major deviations from best practices or major Gas inefficiency. These issues will not have a significant impact on code execution, do not affect security score but can affect code quality score.
