System Overview
The Tarality Ecosystem audit consists of a standard ERC20 token with the additional functionalities of burnability, mintability and fixed max supply.
The core contract of the system is the following:
Token.sol - The standard ERC20 contract with the additional functionalities of burnability, mintability and fixed max supply.
Privileged roles
Owner: Can mint more tokens as long as the total supply does not surpass the max supply.
Executive Summary
Documentation quality
The total Documentation quality score is 10 out of 10.
Functional requirements are provided.
Technical description is present.
NatSpec is sufficient.
Code quality
The total Code quality score is 10 out of 10.
The code is deployed and satisfies the standards.
Test coverage
Code coverage of the project is 0% (branch coverage).
No tests were given. However, since the audit lines of code does not exceed 250, this does not affect the score.
Security score
Upon auditing, the code was found to contain 0 critical, 1 high, 0 medium, and 0 low severity issues. Out of these, 1 issues have been addressed and resolved, 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
The owner can mint tokens as long as the total supply does not exceed the max supply of 3.547.859.012. This allows the constant burning and minting of tokens since burning decreases the total supply.
Findings
Code ― | Title | Status | Severity | |
|---|---|---|---|---|
| F-2023-0838 | Requirements Violation | fixed | High | |
| I-2023-0204 | Shadowing State Variable | unfixed | Observation | |
| I-2023-0203 | Public Functions That Should Be External | unfixed | Observation |
Identify vulnerabilities in your smart contracts.
Appendix 1. Severity Definitions
When auditing smart contracts, Hacken is using a risk-based approach that considers Likelihood, Impact, Exploitability and Complexity metrics to evaluate findings and score severities.
Reference on how risk scoring is done is available through the repository in our Github organization:
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.
