QUBE Token

QubeToken.adminEmergency(address,address,uint256) (#843-849) ignores return value by IBEP20(addr).transfer(account,amount) (#847)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

Unable to verify that contract auditor is trusted: Certik, Quantstamp, Hacken, Solidity, Paladinsec, Openzeppelin, Verichains

Contract ownership is not renounced (belongs to a wallet)

QubeToken.unlockInternal(address) (#796-823) performs a multiplication on the result of a division:
-reward = store.lockedBalances * (10) / (100) (#802)
-_transfer(address(this),user,reward * (store.totalUnlock - given)) (#821)
Consider ordering multiplication before division.

- seedWallet = _seedWallet (#769)

QubeToken.adminEmergency(address,address,uint256).account (#843) lacks a zero-check on :
- address(account).transfer(amount) (#845)
Check that the address is not zero.

QubeToken.unlockInternal(address) (#796-823) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(store.lockedBalances != 0,Invalid account) (#798)
- require(bool,string)(block.timestamp > store.initialDeadline && block.timestamp > store.instalmentDeadline,unable to unlock now) (#799)
- require(bool,string)(store.totalUnlock != 10,claim exceed) (#800)
- diff > duration_ (#813)
QubeToken.presaleLock(address) (#825-833) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(block.timestamp > store.initialDeadline,unable to unlock now) (#829)
Avoid relying on block.timestamp.
