NOTICE: Breaking changes!

Coinpunk updated to the latest version of SJCL, which has fixed a bug that caused PBKDF2 hashes to be inconsistent from the standard.

This has been fixed, but it will not work with wallets created before this commit. Please be mindful of this when upgrading Coinpunk if you are already running it in production.

Also, we are switching to a release-based system, so you should checkout one of the tagged versions instead of using master. The 0.3 series will not contain any breaking changes, but the 0.4 releases will. So please use a 0.3 release if you are using Coinpunk in production.


Run your own Bitcoin wallet service.

Coinpunk is a web application that allows anyone to run their own self-hosted Bitcoin wallet service that is accessible from your web browser anywhere in the world. It's free, open source, and you can install it on your server right now.

Who uses Coinpunk

Coinpunk is aimed at developers, power users, and sysadmins interested in running their own web-based Bitcoin wallet.

Coinpunk is also used to power, the first fully open source web-based wallet service.


The latest version is a major rewrite that uses hybrid-wallets: encryption is done in the browser via a client-side application, which can be run separately from the server. This makes it much harder for hackers to steal Bitcoins by breaking into servers.

Coinpunk is in beta. It is set to testnet by default, and it is recommended that only developers and testers only use it at this time (especially in production).

  • Fast, lightweight, efficient
  • Responsive design - works well on mobile devices
  • Easily create new accounts
  • Send and receive bitcoins
  • Detailed reports on transactions
  • Ability to create and name new receive addresses ("Website Donations", "Bake Sale", etc)
  • Built with Node.js and HTML5
  • Standards compliant, easy to upgrade - Uses bitcoind via the JSON RPC

Get Started

See the Install Guide, or the OSX Install Guide.

Coinpunk is for Advanced Users

If you've never worked on your own server before, and don't know how to do things like backup your database, I strongly recommend using a desktop client or hosted wallet provider like instead. Coinpunk tries to be simple as possible, but like Gitlab, it does require a lot of knowledge to be run properly.
