CZ Token

CZToken._safeTransferBNB(address,uint256) (contracts/token/CZToken.sol#84-87) sends eth to arbitrary user
Dangerous calls:
- (success) = to.call{value: value}(new bytes(0)) (contracts/token/CZToken.sol#85)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

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

CZToken.withdrawFunc(address,address) (contracts/token/CZToken.sol#75-77) ignores return value by ERC20Upgradeable(token).transfer(recipient,ERC20Upgradeable(token).balanceOf(address(this))) (contracts/token/CZToken.sol#76)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

CZToken.whiteList (contracts/token/CZToken.sol#19) is never initialized. It is used in:
- CZToken._transfer(address,address,uint256) (contracts/token/CZToken.sol#49-64)
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

Contract ownership is not renounced (belongs to a wallet)

ERC20VotesUpgradeable._writeCheckpoint(ERC20VotesUpgradeable.Checkpoint[],function(uint256,uint256) returns(uint256),uint256) (contracts/dependencies/open-zeppelin/token/ERC20/extensions/ERC20VotesUpgradeable.sol#239-253) uses a dangerous strict equality:
- pos > 0 && ckpts[pos - 1].fromBlock == block.number (contracts/dependencies/open-zeppelin/token/ERC20/extensions/ERC20VotesUpgradeable.sol#248)
Don't use strict equality to determine if an account has enough Ether or tokens.

Combination 2: Unchecked transfer + Functions that send Ether to arbitraty destination. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

CZToken.constructor() (contracts/token/CZToken.sol#13-17) uses literals with too many digits:
- _mint(msg.sender,1000000000000 * 1e18) (contracts/token/CZToken.sol#16)
Use: Ether suffix, Time suffix, or The scientific notation

ERC20VotesUpgradeable.__gap (contracts/dependencies/open-zeppelin/token/ERC20/extensions/ERC20VotesUpgradeable.sol#262) is never used in CZToken (contracts/token/CZToken.sol#11-102)
Remove unused state variables.

CZToken.setLockContract(address).lockContract (contracts/token/CZToken.sol#44) lacks a zero-check on :
- LOCK_CONTRACT = lockContract (contracts/token/CZToken.sol#45)
Check that the address is not zero.

Low level call in CZToken._safeTransferBNB(address,uint256) (contracts/token/CZToken.sol#84-87):
- (success) = to.call{value: value}(new bytes(0)) (contracts/token/CZToken.sol#85)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
