Network Capital Token

Smart Contract Audit Report

Audit Summary

Network Capital Token is a new BEP-20 token on the Binance Smart Chain.

For this audit, we reviewed the project team's NetworkCapital contract at 0x6A061bC3bd2F90fc3FE0b305488c32D121D0093E on the Binance Smart Chain Mainnet.

Audit Findings

Informational findings were identified and the team may want to review them.
Date: December 24th, 2022.
Updated: January 10th, 2023 to reflect the renouncing of ownership by the project team.

Finding #1 - NetworkCapital - Informational

Description: Although a Buy fee is applied on transfers, the BUYTAX state variable is set to zero and cannot be modified.

function _transfer(address sender, address receiver, uint256 amount) internal virtual override {
    uint256 taxAmount;

        if(liquidityPool[sender] == true) {
            //It's an LP Pair and it's a buy
            taxAmount = (amount * BUYTAX) / PERCENT_DIVIDER;
}

Recommendation: The team should either remove all logic related to the Buy fee for additional gas savings on transfers or modify the BUYTAX state variable to a value other than zero.

---

Finding #2 - NetworkCapital - Informational

Description: The developmentWallet state variable can never be modified, but is not declared constant.
Recommendation: This state variable could be declared constant for additional gas savings on each reference.

---

Finding #3 - NetworkCapital - Informational

Description: The rewardsPool state variable is not used in the contract.
Recommendation: This state variable should either be removed to reduce contract size and deployment costs or utilized in a way that fits the project team's intended functionality.

Contract Overview

• The total supply of the token is set to 1 million $NETC [1,000,000].
• No mint or burn functions are accessible, though the circulating supply can be decreased by sending tokens to the 0x..dead address.
• At the time of writing this report, there are 265 total token holders. The token allocation is as follows:
  • 90% of the total supply is locked in a Pinksale token locking contract. 59% of these tokens will unlock by January 30th, 2023. The remaining tokens will unlock on May 30th, 2023.
  • The remaining 2.59% of the total supply belongs to a wallet controlled by the team.
  • 1.97% of the total supply is in Pancakeswap liquidity.
  • Of that liquidity, 99.9% of the LP tokens are locked in a Pinksale token locking contract and will unlock on December 30th, 2023.
  
  
• There is a 5% Sell fee on all transfers where the recipient is a Liquidity Pool address set by the team.
• The tokens collected through the Sell fee are sent to the team's Development wallet.
• Ownership has been renounced by the team.
• As the contract is deployed with Solidity v0.8.4, it is protected from overflows/underflows.
• The contract complies with the BEP-20 token standard.

What is a SourceHat Audit?

Typically, a smart contract audit is a comprehensive review process designed to discover logical errors, security vulnerabilities, and optimization opportunities within code. A SourceHat Audit takes this a step further by verifying economic logic to ensure the stability of smart contracts and highlighting privileged functionality to create a report that is easy to understand for developers and community members alike.

How Do I Interpret the Findings?

Each of our Findings will be labeled with a Severity level. We always recommend the team resolve High, Medium, and Low severity findings prior to deploying the code to the mainnet. Here is a breakdown on what each Severity level means for the project:

• High severity indicates that the issue puts a large number of users' funds at risk and has a high probability of exploitation, or the smart contract contains serious logical issues which can prevent the code from operating as intended.
• Medium severity issues are those which place at least some users' funds at risk and has a medium to high probability of exploitation.
• Low severity issues have a relatively minor risk association; these issues have a low probability of occurring or may have a minimal impact.
• Informational issues pose no immediate risk, but inform the project team of opportunities for gas optimizations and following smart contract security best practices.
