 Try to use ``require`` to limit the size of inputs to a reasonable range and use the
 :ref:`SMT checker<smt_checker>` to find potential overflows, or use a library like
-`SafeMath <https://github.com/OpenZeppelin/openzeppelin-solidity/blob/master/contracts/math/SafeMath.sol>`_

 if you want all overflows to cause a revert.
 
 Code such as ``require((balanceOf[_to] + _value) >= balanceOf[_to])`` can also help you check if values are what you expect.
