DogeWheel.processFees(uint256) (DogeWheel.sol#225-245) sends eth to arbitrary user
Dangerous calls:
- marketingWalletAddress.transfer(ethForMarketing) (DogeWheel.sol#235)
- spinWheelAddress.transfer(ethForSpinWheel) (DogeWheel.sol#239)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

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


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.

Ensure that all the return values of the function calls are used.

DogeWheel.setMaxWalletAmount(uint256) (DogeWheel.sol#162-165) should emit an event for:
- maxWalletAmount = amount (DogeWheel.sol#164)
Emit an event for critical parameter changes.

DogeWheel._transfer(address,address,uint256) (DogeWheel.sol#171-223) uses timestamp for comparisons
Dangerous comparisons:
- ! isSelling && taxFreeBuyers[_to] > block.timestamp (DogeWheel.sol#209)
Avoid relying on block.timestamp.

Remove the equality to the boolean constant.

SafeMath.mod(uint256,uint256,string) (SafeMath.sol#142-145) is never used and should be removed
Remove unused functions.

Pragma version^0.6.2 (SafeMath.sol#3) allows old versions
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.

Variable IUniswapV2Router01.addLiquidity(address,address,uint256,uint256,uint256,uint256,address,uint256).amountADesired (IUniswapV2Router.sol#13) is too similar to IUniswapV2Router01.addLiquidity(address,address,uint256,uint256,uint256,uint256,address,uint256).amountBDesired (IUniswapV2Router.sol#14)
Prevent variables from having similar names.

DogeWheel.slitherConstructorVariables() (DogeWheel.sol#13-285) uses literals with too many digits:
- swapTokensAtAmount = 2000000 * (10 ** 18) (DogeWheel.sol#41)
Use: Ether suffix, Time suffix, or The scientific notation

Additional information: link

DogeWheel.swapTokensAtAmount (DogeWheel.sol#41) should be constant
Add the constant attributes to state variables that never change.

Additional information: link

transferOwnership(address) should be declared external:
- Ownable.transferOwnership(address) (Ownable.sol#52-56)
Use the external attribute for functions never called from the contract.
