Electrum-proxy

Electrum server wrapper API for HTTP based apps. Simply mediates TCP (Electrum) and HTTP (any web browser) connections.

Requirements

Node >= 7.x

Setup

npm start ip=127.0.0.1 port=9999

Run npm install

How to run

npm start

Supported calls

Electrum protocol 1.4 is supported only for selected methods.

Note: Use eprotocol=1.4 param in case a server doesn't support any versions below 1.4. In other cases don't use eprotocol param at all.

Refer to Electrum Server doc for method specific params and outputs https://github.com/kyuupichan/electrumx/blob/master/docs/PROTOCOL.rst

All calls are required to have a target Electrum server's IP and a port.
