No, it is not. However, after a formal audit or vulnerability test, Team Moby may consider open-sourcing its add-on features in the near future. Team Moby is able to provide access to its repository to Grant Committee upon request.  Moby is currently undergoing a full security audit by Omniscia and has completed a vulnerability test by Pessimistic's Slitherin, a tool fully endorsed by Arbitrum Foundation. Moby plans to also work with Hacken for a 24/7 vulnerability detection service. Repository links for Moby may still be shared upon request from the Grant Committee.
