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.
