Project overview - Lucky Squid Game

Type ERC20/BEP20
Language Solidity
Request date 2022/06/23
Latest Revision date 2022/06/23
Description

Lucky SquidGame is built as a token for fans of the world famous movie SquidGame. In the crypto market we participate as well as the characters in the squidgame film, in addition to bravery, there must also be an element of luck. We want to bring the game world to the whole community of lucky squidgame where all LSG holders are lucky and winners.

Audit Scope

This audit covered the following files listed below with a SHA-1 Hash. The above token Team provided us with the files that needs to be tested.

We will verify the following claims:
  • Correct implementation of Token standard
  • Deployer cannot mint any new tokens
  • Deployer cannot burn or lock user funds
  • Deployer cannot pause the contract
  • Overall checkup (Smart Contract Security)
The auditing process follows a routine series of steps:
  • Review of the specifications, sources, and instructions provided to SolidProof to make sure we understand the size, scope, and functionality of the smart contract.
  • Manual review of code, which is the process of reading source code line-by-line in an attempt to identify potential vulnerabilities.
  • Comparison to specification, which is the process of checking whether the code does what the specifications, sources, and instructions provided to SolidProof describe.
  • Test coverage analysis, which is the process of determining whether the test cases are actually covering the code and how much code is exercised when we run those test cases.
  • Symbolic execution, which is analysing a program to determine what inputs causes each part of a program to execute.
  • Best practices review, which is a review of the smart contracts to improve efficiency, effectiveness, clarify, maintainability, security, and control based on the established industry and academic practices, recommendations, and research.
  • Specific, itemized, actionable recommendations to help you take steps to secure your smart contracts.

A file with a different Hash has been modified, intentionally or otherwise, 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.

Audit details

Throughout the review process, care was taken to evaluate the repository for security-related issues, code quality, and adherence to speciïŹcation and best practices. To do so, reviewed line-by-line by our team of expert pentesters and smart contract developers, documenting any issues as there were discovered.

Risk represents the probability that a certain source-threat will exploit vulnerability, and the impact of that event on the organization or system. Risk Level is computed based on CVSS version 3.0.

#1 | Missing Events Arithmetic (events-maths)
Severity Location Status
Low LuckySquidGame.sol: 408-412, 456-458 Pending
Description

Emit an event for critical parameter changes.

#1 | Functions that are not used (dead-code)

Description

Remove unused functions.

#1 | State variables that could be declared constant (constable-states)
Severity Location Status
Optimization LuckySquidGame.sol: 334 Pending
Description

Add the `constant` attributes to state variables that never change.

#2 | Public function that could be declared external (external-function)
Severity Location Status
Optimization LuckySquidGame.sol: 281-283, 288-290, 309-313, 368-372, 459-461 Pending
Description
