report
Token seems to be a scam (type: phishing / airdrop scam).


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


Contract ownership is not renounced (belongs to a wallet)

ERC1967Upgrade._upgradeToAndCallUUPS(address,bytes,bool).slot (#452) is a local variable never initialized
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

Variable 'ERC1967Upgrade._upgradeToAndCallUUPS(address,bytes,bool).slot (#452)' in ERC1967Upgrade._upgradeToAndCallUUPS(address,bytes,bool) (#441-459) potentially used before declaration: require(bool,string)(slot == _IMPLEMENTATION_SLOT,ERC1967Upgrade: unsupported proxiableUUID) (#453)
Move all variable declarations prior to any usage of the variable, and ensure that reaching a variable declaration does not depend on some conditional if it is used unconditionally.

ERC1967Upgrade._upgradeBeaconToAndCall(address,bytes,bool) (#534-544) ignores return value by Address.functionDelegateCall(IBeacon(newBeacon).implementation(),data) (#542)
Ensure that all the return values of the function calls are used.

Low level call in Address.functionStaticCall(address,bytes,string) (#251-260):
- (success,returndata) = target.staticcall(data) (#258)
Low level call in Address.functionCallWithValue(address,bytes,uint256,string) (#222-233):
- (success,returndata) = target.call{value: value}(data) (#231)
Low level call in Address.functionDelegateCall(address,bytes,string) (#278-287):

Low level call in Address.sendValue(address,uint256) (#154-159):
- (success) = recipient.call{value: amount}() (#157)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
