Token 11 months

$DogeBUSD was created by two crypto enthusiasts who are also very good friends and have been in the crypto space for several years. We have all been scammed at some point during our crypto journey and we wanted to release a token that was 100% safe that will give back to our investors.

DividendDistributor.distributeDividend(address) (#353-364) ignores return value by BUSD.transfer(shareholder,amount) (#359)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

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


Combination 3: Reentrancy vulnerabilities + Unchecked transfer vulnerability. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

Reentrancy in DividendDistributor.setShare(address,uint256) (#286-300):
External calls:
- distributeDividend(shareholder) (#288)
- BUSD.transfer(shareholder,amount) (#359)
State variables written after the call(s):
- shares[shareholder].amount = amount (#298)
- shares[shareholder].totalExcluded = getCumulativeDividends(shares[shareholder].amount) (#299)
Apply the check-effects-interactions pattern.

DogeBUSD.swapBack() (#582-623) ignores return value by router.addLiquidityETH{value: amountBUSDLiquidity}(address(this),amountToLiquify,0,0,autoLiquidityReceiver,block.timestamp) (#613-620)
Ensure that all the return values of the function calls are used.

DogeBUSD.setTargetLiquidity(uint256,uint256) (#727-730) should emit an event for:
- targetLiquidity = _target (#728)
- targetLiquidityDenominator = _denominator (#729)
Emit an event for critical parameter changes.

DogeBUSD.setFeeReceivers(address,address)._marketingFeeReceiver (#717) lacks a zero-check on :
- marketingFeeReceiver = _marketingFeeReceiver (#719)
Check that the address is not zero.

DogeBUSD.isOverLiquified(uint256,uint256) (#749-751) uses timestamp for comparisons
Dangerous comparisons:
- getLiquidityBacking(accuracy) > target (#750)
Avoid relying on block.timestamp.

Address._functionCallWithValue(address,bytes,uint256,string) (#53-69) uses assembly
- INLINE ASM (#61-64)
Do not use evm assembly.

DividendDistributor.process(uint256) (#322-346) has costly operations inside a loop:
- currentIndex ++ (#343)
Use a local variable to hold the loop computation result.

Additional information: link

Context._msgData() (#77-80) is never used and should be removed
Remove unused functions.

Additional information: link

DogeBUSD.swapThreshold (#458) is set pre-construction with a non-constant function or state variable:
- _totalSupply / 5000
Remove any initialization of state variables via non-constant state variables or function calls. If variables must be set upon contract deployment, locate initialization in the constructor instead.

solc-0.7.4 is not recommended for deployment
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.

Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#53-69):
- (success,returndata) = target.call{value: weiValue}(data) (#56)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Additional information: link

Variable DogeBUSD._allowances (#415) is not in mixedCase
Follow the Solidity naming convention.

Additional information: link

Redundant expression "this (#78)" inContext (#72-81)
Remove redundant statements if they congest code but offer no value.

Additional information: link

Variable IDEXRouter.addLiquidity(address,address,uint256,uint256,uint256,uint256,address,uint256).amountADesired (#183) is too similar to IDEXRouter.addLiquidity(address,address,uint256,uint256,uint256,uint256,address,uint256).amountBDesired (#184)
Prevent variables from having similar names.

Additional information: link

DogeBUSD.slitherConstructorVariables() (#397-757) uses literals with too many digits:
- distributorGas = 500000 (#451)
Use: Ether suffix, Time suffix, or The scientific notation

Additional information: link

DogeBUSD.cooldownTimer (#455) is never used in DogeBUSD (#397-757)
Remove unused state variables.

Additional information: link

DogeBUSD.marketingFee (#423) 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) (#165-169)
Use the external attribute for functions never called from the contract.
