XPS [X-PARALLEL SPACE] Token

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

Contract name (X-PARALLEL SPACE) contains non-alphanumeric characters.
Not a direct threat, but may indicate unreliable intentions of developer. Non-alphanumeric chars (,.;!#*&") are extremely rare among low risk tokens.

Low level call in Address.sendValue(address,uint256) (contracts/public/Address.sol#52-58):
- (success) = recipient.call{value: amount}() (contracts/public/Address.sol#56)
Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (contracts/public/Address.sol#118-139):
- (success,returndata) = target.call{value: weiValue}(data) (contracts/public/Address.sol#122)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
