Low level call in Address.sendValue(address,uint256) (#320-326):
- (success) = recipient.call{value: amount}() (#324)
Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#386-407):
- (success,returndata) = target.call{value: weiValue}(data) (#390)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
