DBat Token - Smart Contract Audit Report

Summary

DBat ($DBAT) is a new community-driven BEP20 token.

The DBat Token contract is deployed at 0x27175b67feb102b8c0202fe045b89e3537683491 on the Binance Smartchain mainnet.

Notes on the Contract:
The total supply of the token is set to 1 billion $DBAT [1,000,000,000].
The contract utilizes a minter role that allows the assigned address to mint any amount of tokens to any account at any time.
No burn functions are present; though the circulating supply can be reduced by sending tokens to the 0x..dead address, if desired.

There is a tax fee on all transactions for any non excluded address that participates in a transfer. The tax fee percentages differ depending on if you are either buying tokens or selling tokens to Pancakeswap.
The tokens collected from the tax fee are sent to the team's 'receiveTaxAddress' wallet
A tax fee is not charged on transactions where the team's 'mmAddress' is either the sender or the recipient.
The contract includes functionality to interact with an external unverified antibot contract. This contract was out of scope for the purpose of this audit.
As the project is implemented with Solidity v0.8.0, it is protected from overflows.

Ownership Controls:
Ownership has not been renounced.
The owner has the ability to modify the tax fee percentages to any values at any time.
The owner has the ability to update the team's TaxAddress and mmAddress to any addresses at any time.
The address assigned to the Default_Admin_Role has the ability to add to add/remove addresses to the Minter role at any time.
Audit Findings Summary
No external threats were identified.
We recommend that the team renounces ownership.
Please ensure trust in the team prior to investing as they have substantial control in the ecosystem.
