BEP20Token._transferBurnAddresses (contracts/libs/token/BEP20/BEP20Token.sol#52) is never initialized. It is used in:

BEP20Token._enableFee (contracts/libs/token/BEP20/BEP20Token.sol#54) is never initialized. It is used in:

Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

MUFCToken._safeTransferBNB(address,uint256) (contracts/MUFCToken.sol#73-76) sends eth to arbitrary user
Dangerous calls:
- (success) = to.call{value: value}(new bytes(0)) (contracts/MUFCToken.sol#74)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

MUFCToken.withdrawFunc(address,address) (contracts/MUFCToken.sol#50-52) ignores return value by BEP20Token(token).transfer(recipient,BEP20Token(token).balanceOf(address(this))) (contracts/MUFCToken.sol#51)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

MUFCToken._writeCheckpoint(address,uint32,uint256,uint256) (contracts/MUFCToken.sol#313-331) uses a dangerous strict equality:
- nCheckpoints > 0 && checkpoints[delegatee][nCheckpoints - 1].fromBlock == blockNumber (contracts/MUFCToken.sol#323)
Don't use strict equality to determine if an account has enough Ether or tokens.

BEP20Token._transfer(address,address,uint256) (contracts/libs/token/BEP20/BEP20Token.sol#273-299) contains a tautology or contradiction:
- _balances[sender].sub(amount).sub(receiedAmount) < 0 (contracts/libs/token/BEP20/BEP20Token.sol#289)
Fix the incorrect comparison by changing the value type or the comparison.

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.

MUFCToken.permit(address,address,uint256,uint256,uint8,bytes32,bytes32) (contracts/MUFCToken.sol#124-148) uses timestamp for comparisons

Dangerous comparisons:
