Owner privileges

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.
Token transfer can be locked Owner can lock user funds with owner functions.
Token can be burned There is a function to burn tokens in the contract.
Ownership is not renounced Contract can be manipulated by owner functions.
Comments

Ownership Privileges:

  • The Owner can Enable/Disable trading anytime. Although in the comment on L1004 it is mentioned that "once enabled, can never be turned off", but the is no check in the code for it. Hence, the owner can change the status of 'trading active' to true or false at any time.
  • Remove limits and disable transfer delay.
  • Change the minimum amount of tokens to sell from fees but within a range.
  • Update/Set the maximum transaction amount but not lower than 0.1%
  • Update/Set the maximum wallet amount
  • Include/Exclude wallets from the maximum transaction limit and fees
  • Disable the swap and lock user funds
  • Update/Set buy and sell fees but less than or equal to 25%
  • Set a new AMM, marketing wallet, and dev wallet
  • Set auto LP burning settings within a range on L1294
  • Burn 10% of tokens in LP every 30 minutes (by default) and also update the lp burn frequency at a minimum of 10 minutes which means the owner can manipulate the price of the token

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.

low Issues

Pending

#1 Issue

Local variables shadowing (shadowing-local)

Shinigami.sol

L965

Description

Rename the local variables that shadow another component.

Pending

#2 Issue

Missing Events Arithmetic (events-maths)

Shinigami.sol

L1005-1076

L1294-1300

Description

Emit an event for critical parameter changes.

Pending

#3 Issue

Redundant Code

Shinigami.sol

L1302

Description

The "_basicTransfer" function is redundant because it has no instructions inside it rather than an event emission.

Pending

#4 Issue

Dangerous usage of `tx.origin` (tx-origin)

Shinigami.sol

L1133

Description

Do not use `tx.origin` for authorization. An attacker can bypass the transfer-delayed functionality. We recommend using msg.sender for verification of the sender

informational Issues

Pending

#1 Issue

Unused return values (unused-return)

Shinigami.sol

L1236-1249

Description

Ensure that all the return values of the function calls are used.
