Low level call in Address.sendValue(address,uint256) (Address.sol#54-59):
- (success) = recipient.call{value: amount}() (Address.sol#57)
Low level call in Address.functionCallWithValue(address,bytes,uint256,string) (Address.sol#122-133):
- (success,returndata) = target.call{value: value}(data) (Address.sol#131)
Low level call in Address.functionStaticCall(address,bytes,string) (Address.sol#151-160):
- (success,returndata) = target.staticcall(data) (Address.sol#158)
Low level call in Address.functionDelegateCall(address,bytes,string) (Address.sol#178-187):
- (success,returndata) = target.delegatecall(data) (Address.sol#185)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
