SpankCard

In-browser micropayments wallet.

Usage

To use SpankCard one has to plug it into a web page as yet another javascript library. In future, it will be available as an NPM package. For now, one has to put this to the web page code:

Development

Prerequisites

You are expected to have yarn package manager installed globally on your machine. For installation instructions go to the official web site.

Install

git clone https://github.com/SpankChain/SpankCard
cd SpankCard
yarn install

Rename development.env to .env and set some environment variables:

FRAME_PORT=9090
HARNESS_PORT=9999
CONTRACT_ADDRESS=0x**************************
RPC_URL=

Run

yarn run harness

That command starts a web server to play with SpankCard on localhost. Open browser on http://localhost:9999 and click on some buttons.

WTF is Harness

It demonstrates SpankCard work on localhost. It runs a web page (SpankCard client) on localhost:9999. Serves SpankCard frame (stores privateKeys a-la MetaMascara) from localhost:9090. Different ports make the browser think the pages belong to different origins, thus should be secured against each other malicious behaviour.
