MOBot, the chatbot that sends and receives MOB on the Signal private messaging network, is officially going open source this Friday, July 30th, 2021.

An ideal partner for merchants looking to sell their goods or services on the Signal network, MOBot interacts with users to automatically manage lightweight transactions directly within a chat.

In accordance with MobileCoin’s commitment to integrity and transparency, MOBot will join the MobileCoin blockchain consensus software, fog service, desktop wallet, mobile SDKs, and server APIs on GitHub as an open-source tool under the MIT license.

People shouldn’t wonder how their privacy software works or what its code is doing. MobileCoin wants to empower individuals to take direct control of their privacy and enable independent developers to craft user-protecting MOB commerce solutions.

To begin creating your own bot, head over to Github now.



The MobileCoin consensus network will be updated to version 1.1.0 of the Consensus Protocol software, and MobileCoin Fog will be updated to version 1.1.0 of the Fog software today.

The big change in this release is the lowering of the network fees to 0.0004 MOB.

Servers will be temporarily down during the upgrade process. The maintenance window is from 11am to 1pm, pacific time, on June 24. Upon update, your clients will continue to work, but you will need new clients in order to utilize the lower fee.

Clients can be found as binaries and packages at:


Please join us in testing, and as always, let us know if you have any issues.



Today we are releasing the first two chapters of The Mechanics of MobileCoin, a new book discussing the MobileCoin protocol in detail.

We’d like to thank Koe for authoring this book. It’s a huge undertaking and we appreciate their dedication to helping explain all the tech we’ve built. If you have questions, please reach out here or on the github.

Additional chapters will be released as they become available.
