white paper

Aurum is the gold standard of rewards tokens and BSC security.

Our powerful tokenomics allows holders to freely choose ANY BSC token to be automatically redistributed as a reward straight to their wallet such as BNB, BUSD, CAKE, SAFEMOON or Binance peg tokens like ETH, XRP and ADA.

Utility of the token will come in the form of our secure BSC token wallet, with Aurum as the native currency. Holding Aurum will also unlock functions of a cryptocentric security browser that prevents users from being hacked, rugged or scammed whilst browsing and investing within the crypto space.

AURUMFinance.addLiquidity(uint256,uint256) (#1848-1863) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,liquidityWallet,block.timestamp) (#1854-1861)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

AURUMFinance.swapBack(uint256).success (#1812) is written in both
(success,None) = address(operationsWallet).call{value: amountBNBOperations}() (#1818)

Fix or remove the writes.

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.

AURUMFinance._transfer(address,address,uint256) (#1717-1788) performs a multiplication on the result of a division:
-fees = amount.mul(totalFees).div(100) (#1761)
-fees = fees.mul(sellFeeIncreaseFactor).div(100) (#1765)
Consider ordering multiplication before division.
