A beginner’s guide to MythX

By Mike Pumphrey | Tuesday, November 26th, 2019

A detailed, step-by-step howto guide on how to use MythX with Remix, showing as well as the differences between MythX and MythX Pro.

MythX is a tool for finding smart contract weaknesses. For our single developers and dev teams, we offer two plans: MythX and MythX Pro.

(We also offer custom plans too; contact us for details.)

We recently posted about the differences between MythX and MythX Pro. But you may find it more useful to see an actual scenario involving testing a smart contract using MythX.

Let’s meet Sam.

MythX Pro Security Analysis Explained

By Bernhard Mueller | Tuesday, November 19th, 2019

MythX recently went live with a new Pro upgrade that offers more powerful analysis features than the free version. In this article I’ll explain how the new “full” analysis mode affects the performance of MythX.

MythX is a smart contract security service that integrates multiple analysis techniques. The MythX Pro plan comes with a new analysis mode called Full mode. In this mode, submitted contracts are subjected to a thorough fuzzing campaign and deep inspection using symbolic analysis. It discovers complex security issues and can be used for checking the correctness of smart contracts.


When you submit a smart contract to MythX, the analysis service spawns a number of workers that perform various analysis tasks in parallel. Each worker is given a maximum time budget it may spend on testing the code. The more computing time is available, the higher the coverage achieved by the analysis engine (at the cost of having to wait longer for the results).

Stepping into the light

By Mike Pumphrey | Tuesday, November 12th, 2019

MythX comes into its own, and creates a partnership with ConsenSys Diligence.

I would like to introduce you to the new MythX blog.

This is the place for the whole MythX team, including our researchers, developers, and (yes) marketing folks to be able to share news, tips, ideas, and consolation/hope for the state of security on the Ethereum platform.

(Looking for our old blog? It’s here.)

But first, some orientation, and how we got here.
