UBi Info

ubionline.io

UBi is a platform for all users/influencers/ creators that can freely express themselves on our platform. Many content creators use different social media platforms adding value to web2 platforms. This token is a deflationary token through which the total supply of the token will decrease at a certain burnrate. for more details refer to the tokenomics of this project : https://ubionline.gitbook.io/ubi/tokenomics.

Summary and Final Words

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 can blacklist addresses

It is 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.

Final Words

The following provides a concise summary of the audit report, accompanied by insightful comments from the auditor. This overview captures the key findings and observations, offering valuable context and clarity.


Ownership Privileges
  • The owner can blacklist wallets.
  • The owner can whitelist addresses from burn fees.
  • The owner can change the burn rate which will be used to update the burn fee.
  • The owner can update the burn fees which will be smaller than the previous fees.

Note - This Audit report consists of a security analysis of the UBi Token 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 UBi team, other contracts associated with the project were not audited by our team. We recommend investors to do their own research before investing.

Scope of Work

Files and details

This audit covered the following files listed below with a SHA-1 Hash. The Team mentioned above provided us with the files that need to be evaluated.

The auditing process follows a routine series of steps:
  1. Review the specifications, sources, and instructions provided to SolidProof to ensure we understand the smart contract's size, scope, and functionality.
  2. Manual review of code, which is the process of reading source code line-by-line in an attempt to identify potential vulnerabilities.
  3. Specification comparison checks whether the code does what the specifications, sources, and instructions provided to SolidProof describe.
  4. Test coverage analysis determines whether the test cases are actually covering the code and how much code is exercised when we run those test cases.
  5. Symbolic execution is analyzing a program to determine what inputs cause each part of a program to execute.
  6. Based on the established industry and academic practices, recommendations, and research, best practices review smart contracts to improve efficiency, effectiveness, clarity, maintainability, security, and control.
  7. Specific, itemized, actionable recommendations to help you take steps to secure your smart contracts.

A file with a different Hash has been intentionally or otherwise modified 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.

Findings and Audit result

low Issues | 3 findings

Pending

#1 low Issue
Floating Pragma Solidity Version
UBiOnline.sol
L4
Description

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

Pending

#2 low Issue
Variable visibility missing
UBiOnline.sol
L570
Description

It is recommended to add private visibility to the variables that start with an underscore. Here, mapping is created without any visibility in the blacklist contract.

Pending

#3 low Issue
Missing Events Arithmetic (events-maths)
UBiOnline.sol
L597-601
L607-609
Description

Emit an event for critical parameter changes.
