System Overview
The WrappedElon contract is an Ethereum-based smart contract that allows for the wrapping and unwrapping of ELON tokens into a new ERC20 token named WrappedElon. This process is designed to facilitate the use of ELON tokens on blockchain networks that require lower token precision.
Token (WrappedElon):
Name: Dogelon
Symbol: ELON
Decimals: 4
Inherits from OpenZeppelin's ERC20 and Ownable2Step contracts.
Original ELON Token:
Address: 0x761D38e5ddf6ccf6Cf7c55759d5210750B5D60F3 (constant in the contract).
Privileged roles
Owner - the ability to enable or disable wrap and unwrap functionalities.
Executive Summary
Documentation quality
The total Documentation Quality score is 10 out of 10.
Functional requirements are provided
Technical description is provided.
Code quality
The total Code Quality score is 9 out of 10.
The code does not follow the Solidity best practices.
Test coverage
Code coverage of the project is 100% (branch coverage)
All branches are covered with tests.
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 9.8. This score reflects the combined evaluation of documentation, code quality, test coverage, and security aspects of the project.
Risks
No risks have been identified.
Findings
Code ― | Title | Status | Severity | |

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.
