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.

Token cannot be burned

There is no burn function within the contract.

Ownership is renounced

Contract cannot be manipulated by owner functions.

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 can not change any of the contract settings

The contract contains the functionality in which only the unvested tokens will be transferred by the user from the contract.

Note - This Audit report consists of a security analysis of the Light and shadow 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 Light and shadow team. Other contracts associated with the project were not audited by our team. We recommend investors do their own research before investing.

Scope of Work

Files and details

This audit covered the following files listed below with a SHA-1 Hash. The Team mentioned above provided us with the files that need to be evaluated.

The auditing process follows a routine series of steps:
  1. Review the specifications, sources, and instructions provided to SolidProof to ensure we understand the smart contract's size, scope, and functionality.
  2. Manual review of code, which is the process of reading source code line-by-line in an attempt to identify potential vulnerabilities.
  3. Specification comparison checks whether the code does what the specifications, sources, and instructions provided to SolidProof describe.
  4. Test coverage analysis determines whether the test cases are actually covering the code and how much code is exercised when we run those test cases.
  5. Symbolic execution is analyzing a program to determine what inputs cause each part of a program to execute.
  6. Based on the established industry and academic practices, recommendations, and research, best practices review smart contracts to improve efficiency, effectiveness, clarity, maintainability, security, and control.
  7. Specific, itemized, actionable recommendations to help you take steps to secure your smart contracts.

A file with a different Hash has been intentionally or otherwise modified after the security review. A different Hash could be (but not necessarily) an indication of a changed condition or potential vulnerability that was not within the scope of this review.

Findings and Audit result

low Issues | 3 findings

Pending

#1 low Issue
Floating pragma solidity version
LightAndShadow.sol
L1360
Description

Adding the constant version of solidity is recommended, as this prevents the unintentional deployment of a contract with an outdated compiler that contains unresolved bugs.

Pending

#2 low Issue
Remove safemath library
LightAndShadow.sol
L401-600
Description

The compiler version above 0.8.0 has the ability to control arithmetic overflow/underflow. It is recommended to remove the unwanted code in order to avoid high gas fees.

Pending

#3 low Issue
Missing events
LightAndShadow.sol
L1574-1577
Description

Emit all the critical parameter changes.
