System Overview
Astra Protocol is an ERC-20:
Token — simple ERC-20 token that mints all initial supply to a specific address. Additional minting is not allowed. It has the following attributes:
Name: ASTRA PROTOCOL.
Symbol: ASTRA.
Decimals: 18.
Total supply: 1bn tokens.
Executive Summary
Documentation quality
The total Documentation quality score is 8 out of 10.
Documentation is not well organized, the information related to this audit’s scope is quite limited compared to the amount of documentation provided.
Code quality
The total Code quality score is 10 out of 10.
Test coverage
Code coverage of the project is 0% (branch coverage).
Security score
Upon auditing, the code was found to contain 0 critical, 0 high, 0 medium, and 0 low severity issues. Out of these, 0 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 9.8. This score reflects the combined evaluation of documentation, code quality, test coverage, and security aspects of the project.
Risks
Functionalities such as Token vesting, lock-up, rewards and burn are not implemented in this contract, and are supposed to be executed by secondary contracts, which are not in the scope of this audit.
100% of the token supply is stored in regular EOA addresses that do not correspond to the token distribution amounts outlined in the tokenomics documentation.
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.
