Project Dreams aims to educate and bring awareness to decentralized finance by using different platoforms. Project Dreams podcast will host several DeFi project developers, experienced DeFi traders and knowledgeable DeFi individuals to share their experinces within the Defi industry. We connect the community to emerging and existing Defi projects by giving project developers a platform to share the details about their projects. Project Dreams will be launching a token and documenting the whole experience to share with listeners on their podcast. Listeners will get to have a in-depth analysis of what it is like to start their own DeFi project.

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 can set high fees Contract owner is able to set fees above 25%. Very high fees can also prevent token transfer.
Token transfer can be locked Owner can lock user funds with owner functions.
Token cannot be burned There is no burn function within the contract.
Ownership is not renounced Contract can be manipulated by owner functions.
Comments

The owner can authorize/unauthorize multiple accounts/wallets/contract addresses to perform certain actions in the contract and these addresses can perform these actions even after the ownership is renounced.

Authorized Privileges:

  • Trigger buyback, clear buyback multiplier
  • Set auto buyback settings with any arbitrary values
  • Set buyback multiplier settings within the range
  • Set transaction limit but not to zero or less than zero
  • Exempt accounts from dividends and fees
  • Set fee receivers, distribution criteria, swap back settings, and target liquidity with arbitrary values

OnlyToken Privileges:

The token address will be set as the deployer address of the dividend contract and it can perform certain actions:

  • Distribution Criteria
  • Set Share
  • Deposit
  • Process accounts

 

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.

medium Issues

Pending

#1 Issue

Fees can be 100% or more

ProjectDreams.sol

-

Description

The fees can be set up to 100% or more which may cause the transfers to revert

#3 Issue

Floating Pragma

ProjectDreams.sol

-

Description

The current pragma Solidity directive is “^0.8.0". Contracts should be deployed with the same compiler version and flags that they have been tested thoroughly. Locking the pragma helps to ensure that contracts do not accidentally get deployed using other versions.

Pending

#4 Issue

Contract doesn’t import npm packages from source (like OpenZeppelin etc.)

ProjectDreams.sol

-

Description

We recommend importing all packages from npm directly without flattening the contract. Functions could be modified or can be susceptible to vulnerabilities
