Marscore Library

NPM Package Build Status Coverage Status

A pure and powerful JavaScript Marscoin library.


Marscoin is a powerful new peer-to-peer platform for the next generation of financial technology. The decentralized nature of the Litecoin network allows for highly resilient marscoin infrastructure, and the developer community needs reliable, open-source tools to implement marscoin apps and services.

Get Started

npm install marscore-lib
bower install marscore-lib


The complete docs are hosted here: marscore documentation. There's also a marscore API reference available generated from the JSDocs of the project, where you'll find low-level details on each marscore utility.

To get community assistance and ask for help with implementation questions, please use our community forums.



We're using Marscore in production, as are many others, but please use common sense when doing anything related to finances! We take no responsibility for your implementation decisions.

If you find a security issue, please email


Please send pull requests for bug fixes, code optimization, and ideas for improvement. For more information on how to contribute, please refer to our CONTRIBUTING file.

Building the Browser Bundle

To build a marscore-lib full bundle for the browser:

gulp browser

This will generate files named marscore-lib.js and marscore-lib.min.js.

You can also use our pre-generated files, provided for each release along with a PGP signature by one of the project's maintainers. To get them, checkout a release commit (for example, for v0.12.6).

To verify signatures, use the following PGP keys:

Development & Tests

npm install --global gulp-cli
git clone
cd marscore-lib
npm install

Run all the tests:

gulp test

You can also run just the Node.js tests with gulp test:node, just the browser tests with gulp test:browser or create a test coverage report (you can open coverage/lcov-report/index.html to visualize it) with gulp coverage.
