EtherScanner

Module for parse ethereum transactions or block and get from them all Eth transfers (normal and "internal")

Warning

To work the module need this correction - https://github.com/ethereum/go-ethereum/pull/15297. So you must use geth version 1.7.3 or higher

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:

[{
