DogeTwit is the first project of the Dogecoin ecosystem built on the BSC (Binance Smart Chain). DogeTwit is a combination of Dogecoin and Twitter: Dogeverse, building a social network that allows users to share memes and GIFs on the metaverse. To help users easily create and share content, DogeTwit integrates meme creation and NFT marketplace. Platform users can earn rewards such as native tokens or receive NFT items.

Owner privileges

Critical issues found The contract does contain issues of high or medium criticality. In some circumstances, the Contract may not function as intended and may pose a safety risk.
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 not renounced Contract can be manipulated by owner functions.
Comments

  • Excluded addresses cannot call the deliver function

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 Issue

Owner can regain ownership

DogeTwit.sol

L148-160

Description

The owner is able to call the "lock" function to set the "_previousOwner". Now the owner is able to call the "unlock" function to get the ownership back also if the ownership was transferred to another address. We recommend you to set the "_previousOwner" in the "unlock" function also to address zero while transferring the ownership.

#1 Issue

Local variables shadowing (shadowing-local)

DogeTwit.sol

L225

L396

Description

Rename the local variables that shadow another component.

Pending

#2 Issue

Missing Events Arithmetic (events-maths)

DogeTwit.sol

L314-317

L319-322

Description

Emit an event for critical parameter changes.

#1 Issue

Remove SafeMath library

DogeTwit.sol

-

Description

We recommend you to remove the SafeMath library since the pragma version is above 0.8.x. It is implemented by default.

Pending

#2 Issue

Cannot take out the address balance

DogeTwit.sol

-

Description

Since the contract can receive native tokens, the owner is not able to get out the balance of the contract. We recommend you to implement a function that the owner is able to take out the native token balance of the contract. Otherwise the native tokens are lost.
