NPM version

Installation

npm install etherscanner

Usage

const EtherScanner = require('etherscanner');
const Web3 = require('web3');

let web3Provider = new Web3.providers.HttpProvider(`http://localhost:6082`);
// or if web3 initialized before
let web3Provider = web3.currentProvider;

let etherScanner = EtherScanner(web3Provider);
Get all transfers by transaction hash
etherScanner.scanTransaction('0xc475f8bf9d2721b17f7c09944c2aa32ea943f452cb54ee0aefcb98ead0735274', (err, result) => {
	console.log(result);
});

result:
