SOUND Token

Unable to find manual contract audit (e.g. Certik, PeckShield, Solidity...)

Sound.sendBNBToMarketing(uint256) (#981-984) sends eth to arbitrary user
Dangerous calls:
- _marketingWalletAddress.transfer(address(this).balance) (#983)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Combination 1: Reentrancy vulnerabilities + Functions that send Ether to arbitraty destination. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

- (MAX - (MAX % _tTotal))
Sound._previousTaxFee (#704) is set pre-construction with a non-constant function or state variable:

Remove any initialization of state variables via non-constant state variables or function calls. If variables must be set upon contract deployment, locate initialization in the constructor instead.
