# go-electrum [![GoDoc](https://godoc.org/github.com/d4l3k/go-electrum?status.svg)](https://godoc.org/github.com/d4l3k/go-electrum)
A pure Go [Electrum](https://electrum.org/) bitcoin library. This makes it easy to write bitcoin based services using Go without having to run a full bitcoin node.

![go-electrum](https://rawgit.com/d4l3k/go-electrum/master/media/logo.png)

This is very much WIP and has a number of unimplemented methods. This will eventually be rewritten into a more Go-esque library and handle wallet generation.

Packages provided

* [electrum](https://godoc.org/github.com/d4l3k/go-electrum/electrum) - Library for using JSON-RPC to talk directly to Electrum servers.
* [wallet](https://godoc.org/github.com/d4l3k/go-electrum/wallet) - A bitcoin wallet built on [btcwallet](https://github.com/btcsuite/btcwallet) with Electrum as the backend.
* [irc](https://godoc.org/github.com/d4l3k/go-electrum/irc) - A helper module for finding electrum servers using the [#electrum IRC channel](http://docs.electrum.org/en/latest/protocol.html?highlight=irc#server-peers-subscribe) on Freenode.

## Usage
See [example/](https://github.com/d4l3k/go-electrum/tree/master/example) for more.
