CertRise is formally known as Dogs United Token is in the process of its full rebrand after further discussions between both internal teams and community. By combining our passions in art, utility and safety we are launching safe projects for our partners in the BSC space, with security and joined utility. CertRise will also bring fun to the Defi space through NFT Lottery on a weekly or monthly basis. Depending on the scale of the prize.

CertRise.addLiquidity(uint256,uint256) (#1717-1729) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#1720-1727)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Reentrancy in DividendPayingToken._withdrawDividendOfUser(address) (#721-737):
External calls:
- (success) = user.call{gas: 3000,value: _withdrawableDividend}() (#726)
State variables written after the call(s):
- withdrawnDividends[user] = withdrawnDividends[user].sub(_withdrawableDividend) (#729)
Apply the check-effects-interactions pattern.

CertRise.changeCooldownSettings(bool,uint8) (#1594-1598) contains a tautology or contradiction:
- require(bool,string)(newInterval <= 600,Exceeds the limit) (#1595)
Fix the incorrect comparison by changing the value type or the comparison.

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.
CertRise._transfer(address,address,uint256).claims (#1674) 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.

CertRise.addLiquidity(uint256,uint256) (#1717-1729) ignores return value by uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#1720-1727)
Ensure that all the return values of the function calls are used.

DividendPayingToken.constructor(string,string)._symbol (#678) shadows:
- ERC20._symbol (#329) (state variable)
Rename the local variables that shadow another component.

CertRise.changeCooldownSettings(bool,uint8) (#1594-1598) should emit an event for:
- cooldownTimerInterval = newInterval (#1597)
Emit an event for critical parameter changes.

CertRise.setMarketingWallet(address).wallet (#1486) lacks a zero-check on :
- _marketingWallet = wallet (#1487)
Check that the address is not zero.

Variable 'CertRise._transfer(address,address,uint256).lastProcessedIndex (#1674)' in CertRise._transfer(address,address,uint256) (#1604-1679) potentially used before declaration: ProcessedDividendTracker(iterations,claims,lastProcessedIndex,true,gas,tx.origin) (#1675)
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.

Reentrancy in CERTDividendTracker.processAccount(address,bool) (#1147-1157):
External calls:
- amount = _withdrawDividendOfUser(account) (#1148)
- (success) = user.call{gas: 3000,value: _withdrawableDividend}() (#726)
State variables written after the call(s):
- lastClaimTimes[account] = block.timestamp (#1151)
Apply the check-effects-interactions pattern.

CertRise._transfer(address,address,uint256) (#1604-1679) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(cooldownTimer[from] < block.timestamp,Please wait for cooldown between buys) (#1623)
Avoid relying on block.timestamp.

SafeMathInt.mul(int256,int256) (#155-162) is never used and should be removed
Remove unused functions.

solc-0.8.7 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 CertRise.swapBack(uint256) (#1681-1715):
- (success) = address(dividendTracker).call{value: bnbForReflection}() (#1710)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Variable IUniswapV2Router01.addLiquidity(address,address,uint256,uint256,uint256,uint256,address,uint256).amountADesired (#1234) is too similar to IUniswapV2Router01.addLiquidity(address,address,uint256,uint256,uint256,uint256,address,uint256).amountBDesired (#1235)
Prevent variables from having similar names.
