Sumcore Library

NPM Package Build Status Coverage Status

A pure and powerful JavaScript Sumcoin library.


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

Get Started

npm install sumcore-lib
bower install sumcore-lib


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

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



We're using Sumcore 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 security@bitpay.com.


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 sumcore-lib full bundle for the browser:

gulp browser

This will generate files named sumcore-lib.js and sumcore-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, https://github.com/bitpay/bitcore-lib/commit/e33b6e3ba6a1e5830a079e02d949fce69ea33546 for v0.12.6).

To verify signatures, use the following PGP keys:

Development & Tests

git clone https://github.com/sumcoinlabs/sumcore-lib
cd sumcore-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.
