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 }
Nexo CSV { fileName, loadFileContents }

Base Janitors (Extend them!)

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

Helper Methods

Name Params
resolveConnection { name, type, params }
