VIKINGS [Vikings Inu] Token

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

VIKINGS.includeAccount(address) (#463-474) has costly operations inside a loop:
- _excluded.pop() (#470)
Use a local variable to hold the loop computation result.

Additional information: link

VIKINGS._getTValues(uint256) (#573-577) performs a multiplication on the result of a division:
-tFee = tAmount.div(100).mul(4) (#574)
Consider ordering multiplication before division.

VIKINGS.allowance(address,address).owner (#388) shadows:
- Ownable.owner() (#289-291) (function)
VIKINGS._approve(address,address,uint256).owner (#476) shadows:
- Ownable.owner() (#289-291) (function)
Rename the local variables that shadow another component.

VIKINGS.setMaxTxPercent(uint256) (#422-426) should emit an event for:
- _maxTxAmount = _tTotal.mul(maxTxPercent).div(10 ** 2) (#423-425)
VIKINGS.burnOwnerTokens(address,uint256) (#562-566) should emit an event for:
- _tTotal = _tTotal.sub(_amt) (#565)
Emit an event for critical parameter changes.

VIKINGS.setUniswapPair(address).pair (#603) lacks a zero-check on :
- uniswapPair = pair (#604)
Check that the address is not zero.

VIKINGS._transfer(address,address,uint256) (#484-512) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(block.timestamp >= lastBuy[sender] + transfertimeout,lock 20 seconds after purchase) (#498)
Avoid relying on block.timestamp.

VIKINGS._rTotal (#340) is set pre-construction with a non-constant function or state variable:
- (MAX - (MAX % _tTotal))
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.

Low level call in Address.sendValue(address,uint256) (#182-188):
- (success) = recipient.call{value: amount}() (#186)
Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#248-269):
- (success,returndata) = target.call{value: weiValue}(data) (#252)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
