Status Embark plugin for MythX

Running MythX analyses in Status Embark

GitHub license npm

This plugin brings MythX to Status Embark. Simply call verify from the Embark console and embark-mythx sends your contracts off for analysis. It is inspired by sabre and uses its source mapping and reporting functions.

This project was bootstrapped with TSDX.


  1. Create a .env file in the root of your project and provide your MythX API Key. Free MythX accounts can be created at Once an account is created, generate an API key at

NOTE: MYTHX_ETH_ADDRESS has been deprecated in favour of MYTHX_USERNAME and will be removed in future versions. As of version 2.0, MYTHX_API_KEY is also required. Please update your .env file or your environment variables accordingly.

MYTHX_USERNAME may be either of:

  • MythX User ID (assigned by MythX API to any registered user);
  • Ethereum address, if user account is associated with an address;
  • A verified email address, if the user account is associated with an email address, and that address has been verified by visiting the verification link in the verification email sent by the MythX API each time when user email is set or modified in the MythX settings.

For more information, please see the MythX API Login documentation.

  1. Run verify [options] [contracts] in the Embark console. When the call returns, it will look something like this:

$ npm i embark-mythx
# or 
$ npm i flex-dapps/embark-mythx
  1. Add embark-mythx to the plugins section of your embark.json file. To have the plugin permanently ignore one or multiple contracts, add them to the configuration:
