A pure and powerful JavaScript Bitcoin library.

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

npm install bitcore-lib

bower install bitcore-lib

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

• Generate a random address
• Generate a address from a SHA256 hash
• Import an address via WIF
• Create a Transaction
• Sign a Bitcoin message
• Verify a Bitcoin message
• Create an OP RETURN transaction
• Create a 2-of-3 multisig P2SH address
• Spend from a 2-of-2 multisig P2SH address

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

gulp browser

This will generate files named bitcore-lib.js and bitcore-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 the releases.

git clone https://github.com/bitpay/bitcore-lib
cd bitcore-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.

We're using Bitcore 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.
