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.

Reentrancy in AURUMFinance.buyBackTokensWithNoFees() (#1664-1692):
External calls:
- uniswapV2Router.swapExactETHForTokensSupportingFeeOnTransferTokens{value: ethAmount}(0,path,address(msg.sender),block.timestamp + 360) (#1682-1687)
State variables written after the call(s):
- _isExcludedFromFees[msg.sender] = prevExclusion (#1689)
Apply the check-effects-interactions pattern.

Unable to find manual contract audit (e.g. Certik, PeckShield, Solidity...)
AURUMFinance.swapBack(uint256).success (#1812) is written in both
(success,None) = address(operationsWallet).call{value: amountBNBOperations}() (#1818)
(success,None) = address(teamWallet).call{value: amountBNBTeam}() (#1820)
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.

AURUMFinance._transfer(address,address,uint256).lastProcessedIndex (#1782) is a local variable never initialized
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

AURUMFinance.addLiquidity(uint256,uint256) (#1848-1863) ignores return value by uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,liquidityWallet,block.timestamp) (#1854-1861)
Ensure that all the return values of the function calls are used.

AURUMFinance.constructor().totalSupply (#1344) shadows:
- ERC20.totalSupply() (#525-527) (function)
- IERC20.totalSupply() (#92) (function)
Rename the local variables that shadow another component.

Emit an event for critical parameter changes.

AURUMFinance.updateTeamWallet(address).newWallet (#1495) lacks a zero-check on :
- teamWallet = newWallet (#1496)
Check that the address is not zero.

AURUMFinance.airdropToWallets(address[],uint256[]) (#1469-1477) has external calls inside a loop: dividendTracker.setBalance(address(wallet),balanceOf(wallet)) (#1475)

Variable 'AURUMFinance._transfer(address,address,uint256).lastProcessedIndex (#1782)' in AURUMFinance._transfer(address,address,uint256) (#1717-1788) potentially used before declaration: ProcessedDividendTracker(iterations,claims,lastProcessedIndex,true,gas,tx.origin) (#1783)
Move all variable declarations prior to any usage of the variable, and ensure that reaching a variable declaration does not depend on some conditional if it is used unconditionally.

DividendTracker.canAutoClaim(uint256) (#2073-2079) uses timestamp for comparisons
Dangerous comparisons:
