Contract ownership is not renounced (belongs to a wallet)

FiFi._writeCheckpoint(address,uint32,uint256,uint256) (contracts/FiFiToken.sol#223-241) uses a dangerous strict equality:
- nCheckpoints > 0 && checkpoints[delegatee][nCheckpoints - 1].fromBlock == blockNumber (contracts/FiFiToken.sol#233)
Don't use strict equality to determine if an account has enough Ether or tokens.

Additional information: link

FiFi.updateFeeAddress(address)._newAddress (contracts/FiFiToken.sol#19) lacks a zero-check on :
- feeAddress = _newAddress (contracts/FiFiToken.sol#21)
Check that the address is not zero.

FiFi.getChainId() (contracts/FiFiToken.sol#248-252) uses assembly
- INLINE ASM (contracts/FiFiToken.sol#250)
Do not use evm assembly.

Pragma version^0.8.0 (@openzeppelin/contracts/access/Ownable.sol#4) allows old versions
Pragma version^0.8.0 (@openzeppelin/contracts/utils/Context.sol#4) allows old versions
Pragma version^0.8.0 (@openzeppelin/contracts/utils/math/SafeMath.sol#4) allows old versions
Pragma version0.8.12 (contracts/FiFiToken.sol#3) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
Pragma version>=0.6.4 (contracts/interface/IBEP20.sol#3) allows old versions
Pragma version>=0.4.0 (contracts/libs/BEP20.sol#3) allows old versions
solc-0.8.12 is not recommended for deployment
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.

FiFi.delegateBySig(address,uint256,uint256,uint8,bytes32,bytes32) (contracts/FiFiToken.sol#89-130) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(block.timestamp <= expiry,FiFi::delegateBySig: signature expired) (contracts/FiFiToken.sol#128)
Avoid relying on block.timestamp.

Different versions of Solidity is used:

- ^0.8.0 (@openzeppelin/contracts/access/Ownable.sol#4)
- ^0.8.0 (@openzeppelin/contracts/utils/Context.sol#4)
