About The Crypto Janitor

The Crypto Janitor provides a simple interface for aggregating transactions from multiple sources and attaching a USD value to them. Few exchanges provide the USD value of your transactions at the time they occured. The Crypto Janitor solves this issue, while providing a unified transaction interface.

Features

• Get transactions from
  • Bittrex, Coinbase, Coinbase Pro, and Kucoin via API keys
  • Nexo via CSV import
  • Ethereum Blockchain via address
• Provide unified interface for all transactions

Built With

• ccxt - Used to fetch data from exchange connections
• etherscan-api - Used to fetch data from Ethereum Blockchain

Getting Started

Getting started with The Crypto Janitor is very simple! Just install using the node package manager of your choosing and ba-bam!

Prerequisites

• The Crypto Janitor requires Node.js v12+ to run.

Installation

Install The Crypto Janitor from npm

npm install crypto-janitor

Or with yarn

yarn add crypto-janitor

Usage

Examples

• Get Transactions from an exchange via API.

  import { Coinbase } from "crypto-janitor";
  
  const apiCredentials = {
      apiKey: "<YOUR-API-KEY>",
      apiSecret: "<YOUR-API-SECRET>",
  }
  const coinbaseJanitor = new Coinbase(apiCredentials);
  await coinbaseJanitor.initialize()
  const txs = await coinbaseJanitor.getAllTransactions()

• Get Transactions from Ethereum blockchain via address. (Requires Etherscan API key)

  import { Etherscan } from "crypto-janitor";
  
  const addressCredentials = {
      apiKey: "<ETHERSCAN-API-KEY>",
      address: "<YOUR-ETHEREUM-ADDRESS>",
  }
  const ethJanitor = new Etherscan(addressCredentials);
  await ethJanitor.initialize()
  const txs = await ethJanitor.getAllTransactions()

• Import transactions from Nexo via CSV.

  import * from fs
  import { Nexo } from "crypto-janitor";
  
  loadNexoCsv(filename) {
      // read local csv into buffer and stringify
      const buffer = fs.readFileSync(filename); 
      const fileContentStr = buffer.toString();
  
      // parse file content string and return parsed data
      const results = Papa.parse(fileContentStr, { header: true }); 
      return results.data;
  }
  
  const csvConfig = {
      fileName: "<YOUR-NEXO-TXS.csv>",
      loadFileContents: loadNexoCsv,
  }
  const nexoJanitor = new Nexo(csvConfig);
  await nexoJanitor.initialize()
  const txs = await nexoJanitor.getAllTransactions()

• (RECOMMENDED) Use the resolveConnection function to easily initialize new janitors.

  import { resolveConnection } from "crypto-janitor";
  
  const apiCredentials = {
      apiKey: "<YOUR-API-KEY>",
      apiSecret: "<YOUR-API-SECRET>",
      password: "YOUR-API-PASSWORD"
  }
  const coinbaseproJanitor = await resolveConnection("coinbasepro", "api", apiCredentials);
  const txs = await coinbaseproJanitor.getAllTransactions()

Interface

The Crypto Janitor Interface exposes

• Implemented janitors
• Janitor base classes (so create your own janitors!)
• Helper function to initial janitors based on inputs

Implemented Janitors

Name	Type	Params
Bittrex	API	{ apiKey, secret }
Coinbase	API	{ apiKey, secret }
Coinbase Pro	API	{ apiKey, secret, password }
Kucoin	API	{ apiKey, secret, password }
Etherscan	Address	{ address, apiKey }

Base Janitors (Extend them!)

Name	Type	Params
Base	any	{ name, type, params }
CCXT	API	{ name, credentials, params }
