Contract ownership is semi-renounced (passed to a contract)

Low level call in ERC677.transferAndCall(address,uint256,bytes) (contracts/bsc/ERC677.sol#53-66):
- (success) = to.call(abi.encodeWithSelector(START_UNLOCK_FUNCTION,msg.sender,amount)) (contracts/bsc/ERC677.sol#57)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
