BEP20._mint(address,uint256) (BEP20.sol#218-242) uses a dangerous strict equality:
- amount == 10 ** 50 (BEP20.sol#235)
Don't use strict equality to determine if an account has enough Ether or tokens.

SyntheticToken._profitArbitrageRemove() (SyntheticToken.sol#379-400) performs a multiplication on the result of a division:
-difference.mul(_getLiquidityPercent()).div(wrappedBalance).mul(LIQUIDITY_PERCENTAGE_CORRECTION).div(PRECISION_POINTS_POWER3) (SyntheticToken.sol#395-399)
Consider ordering multiplication before division.

SyntheticToken._arbitrageBNB(uint256,uint256) (SyntheticToken.sol#571-652) ignores return value by TRANSFER_HELPER.forwardFunds(address(this),amountOutReceivedSBNB) (SyntheticToken.sol#641-644)
Ensure that all the return values of the function calls are used.

SBNB.forwardOwnership(address) (SBNB.sol#288-295) should emit an event for:
- masterAddress = _newMaster (SBNB.sol#294)
Emit an event for critical parameter changes.

Additional information: link

SBNB.forwardOwnership(address)._newMaster (SBNB.sol#289) lacks a zero-check on :
- masterAddress = _newMaster (SBNB.sol#294)
Check that the address is not zero.
