SLEEP [Sleep Care] Token

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

SleepCare.includeInReward(address) (#637-648) has costly operations inside a loop:
- _excluded.pop() (#644)
Use a local variable to hold the loop computation result.

SleepCare._rTotal (#495) is set pre-construction with a non-constant function or state variable:
- (MAX - (MAX % _tTotal))
SleepCare._taxFee (#508) is set pre-construction with a non-constant function or state variable:
- _buyTaxFee
SleepCare._previousTaxFee (#509) is set pre-construction with a non-constant function or state variable:
- _taxFee
SleepCare._previousBurn (#513) is set pre-construction with a non-constant function or state variable:
- _burnFee
SleepCare._advestisementFee (#518) is set pre-construction with a non-constant function or state variable:
- _buyAdvestisementFee
SleepCare._previousAdvestisementFee (#519) is set pre-construction with a non-constant function or state variable:
- _advestisementFee
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) (#289-295):
- (success) = recipient.call{value: amount}() (#293)
Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#355-376):
- (success,returndata) = target.call{value: weiValue}(data) (#359)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
