XrpDoge.addLiquidity(uint256,uint256) (#1740-1755) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,liquidityWallet,block.timestamp) (#1746-1753)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

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

Contract locking ether found:
Contract XrpDogeDividendTracker (#1770-1976) has payable functions:
- DividendPayingToken.receive() (#1136-1137)
- DividendPayingToken.distributeDividends() (#1152-1163)
- IDividendPayingToken.distributeDividends() (#488)
But does not have a function to withdraw the ether
Remove the payable attribute or add a withdraw function.

Additional information: link


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.

DividendPayingToken.lastAmount (#1112) is never used in XrpDogeDividendTracker (#1770-1976)
Remove unused state variables.

XrpDoge.tradingEnabledTimestamp (#1316) should be constant
Add the constant attributes to state variables that never change.

XrpDoge._transfer(address,address,uint256) (#1562-1673) performs a multiplication on the result of a division:
-fees = amount.mul(totalFees).div(100) (#1646)
-fees = fees.mul(sellFeeIncreaseFactor).div(100) (#1650)
Consider ordering multiplication before division.

XrpDoge._transfer(address,address,uint256).lastProcessedIndex (#1666) 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.

XrpDoge.addLiquidity(uint256,uint256) (#1740-1755) ignores return value by uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,liquidityWallet,block.timestamp) (#1746-1753)
Ensure that all the return values of the function calls are used.

Variable 'XrpDoge._transfer(address,address,uint256).claims (#1666)' in XrpDoge._transfer(address,address,uint256) (#1562-1673) potentially used before declaration: ProcessedDividendTracker(iterations,claims,lastProcessedIndex,true,gas,tx.origin) (#1667)
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.

XrpDogeDividendTracker.canAutoClaim(uint256) (#1892-1898) uses timestamp for comparisons
Dangerous comparisons:
- lastClaimTime > block.timestamp (#1893)

Avoid relying on block.timestamp.

Variable DividendPayingToken._withdrawDividendOfUser(address)._withdrawableDividend (#1187) is too similar to XrpDogeDividendTracker.getAccount(address).withdrawableDividends (#1834)
Prevent variables from having similar names.

XrpDogeDividendTracker.getAccountAtIndex(uint256) (#1873-1890) uses literals with too many digits:
