GMG [Ghost Magic] Token

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

GhostMagic.airdrop(address) (#1231-1244) sends eth to arbitrary user
Dangerous calls:
- address(address(uint160(_refer))).transfer(referEth) (#1240)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Contract ownership is not renounced (belongs to a wallet)

GhostMagic._writeCheckpoint(address,uint32,uint256,uint256) (#1147-1165) uses a dangerous strict equality:
- nCheckpoints > 0 && checkpoints[delegatee][nCheckpoints - 1].fromBlock == blockNumber (#1157)
Don't use strict equality to determine if an account has enough Ether or tokens.

GhostMagic.delegateBySig(address,uint256,uint256,uint8,bytes32,bytes32) (#1013-1054) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(now <= expiry,tt::delegateBySig: signature expired) (#1052)
Avoid relying on block.timestamp.

Low level call in Address.sendValue(address,uint256) (#520-526):
- (success) = recipient.call{value: amount}() (#524)
Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#599-625):
- (success,returndata) = target.call{value: weiValue}(data) (#608)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
