Vaselabs
Vaselabs is a multichain ecosystem within the blockchain industry. This means that Vaselabs products aren't confined to a single blockchain network; instead, they operate across multiple blockchain platforms.
Owner privileges
Comments
Ownership Privileges
- The owner can pause and un-pause the token transfer for an unlimited period.
- The owner can blacklist/un-blacklist the user from transferring tokens.
- The owner can burn tokens from the blacklisted wallets.
- The owner can claim stuck tokens including the contract tokens.
Note - This Audit report consists of a security analysis of the Vaselabs 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 Vaselabs 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)
- 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 speciïŹcation 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.
high Issues
Pending
#1 Issue
The owner can burn tokens.
L429-435
The owner can burn the tokens from the user's wallets which were blacklisted by the owner as this is not recommended because no burning of tokens should be done without any allowances by the user.
medium Issues
Pending
#1 Issue
The owner can blacklist wallets.
L419-422
The owner can blacklist wallets from transferring tokens as this can lock the funds, which is not recommended. There must be a locking period so that the user is not locked for an indefinite period of time.
Pending
#2 Issue
The owner can lock funds.
L370-373
The contract contains the pausable functionality which can pause and unpause the token transfer which is not recommended as there must be a locking period so that the transferring of tokens should not be locked for an indefinite period of time.
Pending
#3 Issue
The owner can mint tokens.
L585-588
The owner can mint an unlimited amount of tokens after the initial deployment, which is not recommended as this can increase the supply of tokens, which can manipulate the cost. There must be a fixed supply so that the token supply should not be changed after initial deployment.
low Issues
Pending
#1 Issue
Floating pragma solidity version.
L2
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
#2 Issue
Remove safemath library
L133-267
The compiler version above 0.8.0 has the ability to control arithmetic overflow/underflow. It is recommended to remove the unwanted code in order to avoid high gas fees.
informational Issues
Pending
#1 Issue
Functions that are not used (dead-code)
L114-117
Remove unused functions.
optimization Issues
Pending
#1 Issue
Public function that could be declared external (external-function)
L317-320
L326-328
L370-373
L378-381
Use the `external` attribute for functions never called from the contract.
