Fast tracking an unlimited number of ERC20 tokens and Ethereum addresses, even millions.

https://docs.ethplorer.io/monitor

Learn how to start tracking your Ethereum addresses with Ethplorer Bulk API and and Node.js.

Let's create a new project and add eth-bulk-monitor-client-nodejs library via npm.

$ mkdir monitor-example
$ cd monitor-example
$ npm init
$ npm i --save eth-bulk-monitor-client-nodejs
$ vim index.js

Create a new js file and start edit it.

First of all, let's include MonitorApp class:

const { MonitorApp } = require('eth-bulk-monitor-client-nodejs');

Then instantiate the class with your API key.

const monitorApp = new MonitorApp('put your API key here');

Finally, lets define the addresses we would like to monitor and a callback function:

monitorApp.init([
    '0x0000000000000000000000000000000000000001',
    '0x0000000000000000000000000000000000000002',
    '0x0000000000000000000000000000000000000003'
]).then(() => monitorApp.watch((data) => console.log(data));

Voila, now we can get and process all the new transactions and ERC-20 operations for the specified addresses using just a single npm library and Node.js.
