As owner of Cointalk Germany we decided to launch our first Project with our Community Members. We wanted to give our Community a safe place to ape and we are super excited to be on the Arbitrum-Chain. The Arbitrum-Chain is super fast and has lower fees compared to the Ethereum-Chain while also using ETH. We are the Kings and Queens of Arbitrum and now it’s our chance to take a position in this bear market because we are sure that this chain gonna blow up in the next bull run.

Owner privileges

No critical 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.
Comments

Ownership/Authority Privileges:

The contract has two modifiers after the ownership is renounced - onlyToken, and authorized

onlyToken (deployer or distributorOwner address) had the following privileges:

  • Set distribution criteria, min period and min distribution to any arbitrary values including zero
  • Set  shares for any address
  • Deposit ETH in the contract, and process dividends
  • Claim dividend for a shareholder. Hence, the shareholders cannot claim the dividends by themselves
  • Change distributor Owner address
  • Withdraw ETH from the contract

authorized Addresses had the following privileges:

  • Enable/Disable trading and lock user funds
  • Enable/Disable the fee in the contract
  • Set max wallet, and transaction limit
  • End happy hour but cannot start it again
  • Change fees, but cannot set it more than 25%
  • Change swapBack settings and distribution criteria
  • Process Dividends
  • Set router, and pair address
  • Include/Exclude wallets from fee, tx limit, and dividends
  • Change Fee Receiver address

Since the ownership is renounced and the blacklist status is true, the blacklisted wallets can never be removed from the blacklist

Note - The privileges mentioned above are not applicable now as the ownership has been completely renounced. But we cannot confirm whether an authorised address exists or not.

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 specification 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.
