Is there a version of the SafeMath library that is compliant to SOlidity v0.5?
Thanks for your inputs in advance
First of all, there is no single "SafeMath" library, but rather a number of different libraries with the same (or similar) names.
Most widely used (though not necessary the best), is SafeMath library from OpenZeppelin.
The most recent released version 0.2.4 starts with
pragma solidity ^0.5.0;, so I believe, that it is compatible with Solidity 0.5.x.
