Moonbud - Smart Contract Audit Report

Summary

Moonbud Finance Audit Report Moonbud is a deflationary token with frictionless fee redistribution on the Binance Smart Chain.

We audited Moonbud's token contract, deployed at 0xbe8183612f145986a41ad8e8fcfefed1c2f9deba on the BSC mainnet.

Overview of the Contract:
  • The initial total supply of the token is 1 billion. Due to burns, the current total supply is about 963 million.
  • No minting functions are present.
  • Pancakeswap holds ~8% of the total supply as liquidity.
  • 6.3% of the total supply has be sent to the 0xdead address, burning those tokens.
  • The charity wallet holds 3.4% of the supply.
  • The team has locked 7.7% of the supply for 3 months on our recommendation.
  • The next largest holder has 3.2%

  • Users who hold tokens will automatically receive a portion of the fees from a transaction tax.
  • The contract also implements a burn fee and charity fee on each transaction.
  • The funds collected from charity fee will be held in a wallet controlled by the team.
  • In addition, the contract implements a maximum amount of tokens that can be sent in a transaction in the amount of 1 billion. As this is the total supply, this has no impact on user functionality.
  • Ownership has been renounced, to tax fees and the inclusion/exclusion of accounts cannot be altered.
  • The contract utilizes SafeMath libraries to prevent overflows.
Audit Findings Summary
  • No security issues were detected in the analysis.
  • Ensure trust in the team as they control the charity wallet.
