Royal Doge is a BNB reflection token with an online poker room that runs on our token RDOGE. RDOGE is a BEP20 token and runs on the Binance Smart Chain. We built our poker room compatible to accept our BEP20 token before launch, because utility is what our team values the highest.

RoyalDoge.addLiquidity(uint256,uint256) (RoyalDoge.sol#489-504) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,0x000000000000000000000000000000000000dEaD,block.timestamp) (RoyalDoge.sol#495-502)
RoyalDoge.swapAndSendDividends(uint256) (RoyalDoge.sol#506-522) sends eth to arbitrary user
Dangerous calls:
- (success) = address(dividendTracker).call{value: dividends}() (RoyalDoge.sol#517)
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.


Contract ownership is not renounced (belongs to a wallet)

RoyalDoge._transfer(address,address,uint256) (RoyalDoge.sol#355-443) performs a multiplication on the result of a division:
-fees = amount.mul(totalFees).div(100) (RoyalDoge.sol#418)
-fees = fees.mul(sellFeeIncreaseFactor).div(100) (RoyalDoge.sol#421)
Consider ordering multiplication before division.

- nextClaimTime > block.timestamp (RoyalDoge.sol#630-632)
RDDividendTracker.canAutoClaim(uint256) (RoyalDoge.sol#654-660) uses timestamp for comparisons
Dangerous comparisons:
- lastClaimTime > block.timestamp (RoyalDoge.sol#655)
- block.timestamp.sub(lastClaimTime) >= claimWait (RoyalDoge.sol#659)
Avoid relying on block.timestamp.
