eth-local

NOTE: This project is still in development, not all components are functional.

The purpose of eth-local is to offer a standardized way to store your keystore files on your local machine.

The core functionality of this application is the ability of the cli to safely transmit pre-signed tx to a website without the need of having Metamask installed on the browser. The cli runs a simple HTTP server which allows the npm module to connect to it.

./cli is the CLI as well as an express server that can be run optionally.

./web is a create-react-app and will serve as testing ground for the npm module that will interact with the express server in the CLI.

./client is intended to be a daemon (currently just a node app) that initiates an electron app to prompt the user for their password.

Running

1. Start the cli by running cd cli && npm i && node app.js. You will prompted with all availible options. In necessary initiate keystore and create a key pair.

2. Start the dev web app server by running cd web && npm i && npm start.

3. Following the instructions in the dev web app will initiate the elctron prompt.

Details

Cli

• Uses the spawn() library to launch electron prompt (see cli/utils/spawn.js)
• stdin/out are supposed to provide data to and from the electron prompt (WIP)

Client

• /ui is the UI for the electron app, standard create-react-app
• /app is the deployable part, which includes a production build of ui/ (TODO: Setup linkage or change structure so we don't have to copy build from ui/.
• app/main.js is the electron app. This is where you can configure it.
• Launching the electron app on its own may be troublesome, you must run it with electron (eg. electron main.js)

Web

• This is just a front end for testing purposes
