CYBRIA is a Layer 2 blockchain platform built on top of the Ethereum network. It aims to enhance scalability, transaction speed, and security within the Ethereum ecosystem while leveraging Cybersecurity and Artificial Intelligence (AI) technologies to ensure network safety and improve performance CYBRIA is designed to address the limitations of the Ethereum network by providing a scalable, secure, and efficient Layer 2 solution. By utilizing Layer 2 scaling techniques, CYBRIA aims to reduce transaction costs and increase the throughput of the Ethereum network.

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 renounced Contract cannot be manipulated by owner functions.
Comments

The following _taxWallet is currently set and cannot be renounced: 0x746b95fFe1BD7080169125F12e7d96BC09076E32


Owner privileges

  • The owner can set the fees but only reducing. The _finalBuy and _finalSellTax are set to 4 by default.
  • The owner can remove the limits

TaxWallet privileges

  • The taxWallet can call the manualSwap function

The added liquidity during the opening trade is locked for 12 Months. After it the "_taxWallet" owner can get out the liquidity. Locked: https://app.uncx.network/amm/uni-v2/pair/0x4de01f8b87683d22216f412359c29de634a77367

Information for taxes during the transfer:

  • If the buyCount is below 25%, the "_initialBuyTax" (30%) will be set as fee; otherwise, the "_finalBuyTax" (4%) will be used
  • If the sellCount is below 25%, the "_initialSellTax" (30%) will be set as fee; otherwise, the "_finalSellTax" (4%) will be used

The "onlyOwner" function cannot be called because the owner is renounced (https://etherscan.io/tx/0x544315f727eee0552c31a284a83f2f2133ef03e076b19756a6fedb91c818765d), but the EOA "_taxWallet" can call the "manualSwap" function. In the "manualSwap" function, the "swapAndLiquify" will be called. However, the "_taxWallet" will get the marketing part as ETH, and the liquidity will also be added to the "_taxWallet". Since the "_lpFee" is set to 0, the "addLiquidity" function will never be called.

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.
