Neuro - Audit Report

Summary

Neuro Audit Report Neuro is a new token with frictionless fee redistribution and charity contributions on each transfer.

We audited Neuro's token contract contract at 0xd047bd94f90a95b38df6e1ea67796f571f46536b on the Binance Smart Chain mainnet.

Overview of the Contract:
  • The total supply of the token is set to 10,000.
  • The token is designed to be a governance token where 1 token = 1 vote.
  • Token holders can delegate their voting rights to any address. To save gas, users can also do so using an EIP-712 signature.
  • No mint or publicly accessible burn functions are present; though the circulating supply can be reduced by sending tokens to the 0x..dead address, if desired.
  • 50% of the supply has been sent to the 0xdead address.
  • 4.4% of the token's supply is held in the Pancakeswap liquidity pool.
  • 99% of liquidity has been locked for 6 months
  • The project's charity wallet holds 4.15% of the token's supply.
  • The next largest holder has 2%

  • Users who hold tokens will automatically receive a portion the fees from a transaction tax on each transfer.
  • Another portion of the fee charged on transactions is sent to a charity wallet which is controlled by the team.
  • We generally advise renouncing ownership to decrease the centralization of the project, though the team has elected to retain ownership so they can update the charity address.
  • The owner can also update the charity address at any time.
  • The owner of the contract can exclude and include users from transfer fees and update the fee percentages to any amount at any time.
  • Ownership has been renounced on our recommendation, so none of these variables can be changed from their current state.
  • Some functions could have been declared external instead of public to save some gas, but as this is already deployed this is merely informational.
  • The contract utilizes Solidity 0.8.3 which has built-in overflow checks, removing the need for SafeMath.

Audit Findings Summary
  • No security issues were identified in our analysis.
  • Ensure trust in the team as they will collect tokens via the charity wallet.
