Getting Started

The ethers.js library is a compact and complete JavaScript library for Ethereum.

Installing in Node.js

From your project directory:

/Users/ricmoo/my-project> npm install --save ethers

And from the relevant application files:

var ethers = require('ethers');

Including in Web Applications

For security purposes, it is usually best to place a copy of this script on the application’s server, but for a quick prototype using the Ethers CDN (content distribution network) should suffice:

<!-- This exposes the library as a global variable: ethers -->
<script src=""
