UpLink.swapBack() (#736-795) sends eth to arbitrary user
Dangerous calls:
- distributor.deposit{value: amountETHReward}() (#779)
- (success) = address(marketingFeeReceiver).call{gas: 30000,value: amountETHMarketing}() (#780-781)
- (success,None) = address(buyBackFeeReceiver).call{gas: 30000,value: amountETHBuyBack}() (#782-783)
- (success,None) = address(ecosystemFeeReceiver).call{gas: 30000,value: amountETHEco}() (#784-785)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

DividendDistributor.distributeDividend(address) (#323-337) ignores return value by REWARD.transfer(shareholder,amount) (#330)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

Too many vulnerabilities (Unchecked transfer, Reentrancy vulnerability, etc.). High risk of a scam. DYOR & manual audit are advised.

UpLink.swapBack().success (#780) is written in both
(success,None) = address(ecosystemFeeReceiver).call{gas: 30000,value: amountETHEco}() (#784-785)
success = false (#787)
Fix or remove the writes.

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.


Combination 2: Unchecked transfer + 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.


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.

UpLink.slitherConstructorVariables() (#411-1199) performs a multiplication on the result of a division:
-gonMaxWallet = TOTAL_GONS.div(100).mul(100) (#444-445)
Consider ordering multiplication before division.

External calls:

- REWARD.transfer(shareholder,amount) (#330)
State variables written after the call(s):
- currentIndex ++ (#311)
Apply the check-effects-interactions pattern.

UpLink.swapBack() (#736-795) ignores return value by router.addLiquidityETH{value: amountETHLiquidity}(address(this),amountToLiquify,0,0,autoLiquidityReceiver,block.timestamp) (#790-793)
Ensure that all the return values of the function calls are used.

UpLink.setMaster(address) (#556-558) should emit an event for:
- master = _master (#558)
Emit an event for critical parameter changes.

UpLink.setFees(uint256,uint256,uint256,uint256,uint256,uint256) (#1059-1073) should emit an event for:

UpLink.clearStuckBalance(uint256,address).adr (#1118) lacks a zero-check on :
- address(adr).transfer((amountETH * amountPercentage) / 100) (#1122-1123)
Check that the address is not zero.

UpLink.multiSend_v2(address,address[],uint256) (#1155-1176) has external calls inside a loop: distributor.setShare(recipients[i],_gonBalances[recipients[i]].div(shareGonDivisor)) (#1165-1167)
Favor pull over push strategy for external calls.

Reentrancy in UpLink.setIsDividendLocked(address,bool) (#805-817):
External calls:
- distributor.setShare(holder,_gonBalances[holder].div(shareGonDivisor)) (#812-813)

UpLink._transferFrom(address,address,uint256) (#656-734) uses timestamp for comparisons
Dangerous comparisons:
- sender == pair && dividendLockTimer[recipient] < block.timestamp && isDividendLocked[recipient] && ! isDividendExempt[recipient] (#688-689)
Avoid relying on block.timestamp.

Additional information: link

DividendDistributor.process(uint256) (#293-313) has costly operations inside a loop:
- currentIndex ++ (#311)
Use a local variable to hold the loop computation result.

Additional information: link

UpLink.transferToAddressETH(address,uint256) (#1126-1129) is never used and should be removed
Remove unused functions.

Additional information: link

UpLink.totalFee (#450-451) is set pre-construction with a non-constant function or state variable:
- ecosystemFee.add(liquidityFee).add(marketingFee).add(buyBackFee).add(rewardFee)
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.

Pragma version^0.7.4 (#29) 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.

Low level call in UpLink.swapBack() (#736-795):
- (success) = address(marketingFeeReceiver).call{gas: 30000,value: amountETHMarketing}() (#780-781)
- (success,None) = address(buyBackFeeReceiver).call{gas: 30000,value: amountETHBuyBack}() (#782-783)
- (success,None) = address(ecosystemFeeReceiver).call{gas: 30000,value: amountETHEco}() (#784-785)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Variable UpLink.ZERO (#467) is not in mixedCase
Follow the Solidity naming convention.

Additional information: link

Variable IDEXRouter.addLiquidity(address,address,uint256,uint256,uint256,uint256,address,uint256).amountADesired (#380) is too similar to IDEXRouter.addLiquidity(address,address,uint256,uint256,uint256,uint256,address,uint256).amountBDesired (#380)
Prevent variables from having similar names.

Additional information: link

UpLink.slitherConstructorVariables() (#411-1199) uses literals with too many digits:
- distributorGas = 500000 (#488)
Use: Ether suffix, Time suffix, or The scientific notation

SafeMathInt.MAX_INT256 (#170-171) is never used in SafeMathInt (#167-207)
Remove unused state variables.

Additional information: link

UpLink.shareGonDivisor (#494) should be constant
Add the constant attributes to state variables that never change.

Additional information: link

rescueToken_v2(address,uint256,address) should be declared external:
- UpLink.rescueToken_v2(address,uint256,address) (#1110-1116)
Use the external attribute for functions never called from the contract.
