RDOG [RewarDog] Token

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

RewarDog.contractSwap(uint256) (#759-784) sends eth to arbitrary user
Dangerous calls:
- reflector.load{value: amountBNBReflection}() (#779)
- _taxWallets.marketing.transfer(address(this).balance) (#782)
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.

RewarDog.takeTaxes(address,address,uint256) (#735-757) performs a multiplication on the result of a division:
-burnAmount = (((amount * currentFee) / staticVals.masterTaxDivisor) * _ratios.burn) / _ratios.total (#749)
Consider ordering multiplication before division.

Variable 'RewarDog._finalizeTransfer(address,address,uint256,bool).check (#662)' in RewarDog._finalizeTransfer(address,address,uint256,bool) (#652-705) potentially used before declaration: checked = check (#663)
