cryptofy coin is a decentrlized metaverse coin that bridge the gap between the virtual world and the real world by aiding seamless, secured and fast transaction. Its very economical and has fast processing power per seconds powered by the cryptofy smart chain (CSC). As we develop and grow, cryptofy coin plans to expand into additional industries, such as the energy agricultural, and oil and gas sectiors. Cryptofy coin is the game-changer

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.
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.

Note - This Audit report consists of a security analysis of the CryptoFy coin smart contract. This analysis did not include functional testing (or unit testing) of the contract’s logic. Moreover, we only audited one token contract for the CryptoFy coin team. Other contracts associated with the project were not audited by our team. We recommend investors do their own research before investing.

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.

Pending

#1 Issue

Missing Events Arithmetic (events-maths)

CryptofyCoin.sol

L547-549

Description

Emit an event for critical parameter changes.

Pending

#2 Issue

Missing Zero Address Validation (missing-zero-check)

L551

Description

Check that the address is not zero.

Pending

#3 Issue

Floating pragma solidity version.

CryptofyCoin.sol

L6

Description

Adding the constant version of solidity is recommended, as this prevents the unintentional deployment of a contract with an outdated compiler that contains unresolved bugs.

Pending

#4 Issue

Missing 'require' error message.

CryptofyCoin.sol

L501

L510

L528

L542

L556
