Bringing your rugged tokens back from the dead
Unable to find manual contract audit (e.g. Certik, PeckShield, Solidity...)
ZombieToken._writeCheckpoint(address,uint32,uint256,uint256) (contracts/ZombieToken.sol#220-238) uses a dangerous strict equality:
- nCheckpoints > 0 && checkpoints[delegatee][nCheckpoints - 1].fromBlock == blockNumber (contracts/ZombieToken.sol#230)
Don't use strict equality to determine if an account has enough Ether or tokens.

BEP20.allowance(address,address).owner (contracts/token/BEP20/BEP20.sol#122) shadows:
- Ownable.owner() (contracts/access/Ownable.sol#35-37) (function)
BEP20._approve(address,address,uint256).owner (contracts/token/BEP20/BEP20.sol#294) shadows:

Rename the local variables that shadow another component.

ZombieToken.delegateBySig(address,uint256,uint256,uint8,bytes32,bytes32) (contracts/ZombieToken.sol#86-127) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(block.timestamp <= expiry,ZMBE::delegateBySig: signature expired) (contracts/ZombieToken.sol#125)
Avoid relying on block.timestamp.

ZombieToken.whaleDetection(address,uint256) (contracts/ZombieToken.sol#253-260) compares to a boolean constant:
-require(bool,string)(balanceBasisPointsOfTotalSupply <= 200 || launch == false || whitelist[recipient] == true || msg.sender == owner() || tx.origin == owner(),Whale Detection: wallet cannot hold > 2% of total supply at launch.) (contracts/ZombieToken.sol#255-258)
Remove the equality to the boolean constant.
