detect-cryptocoin

node-detect-cryptocoin

Detects which cryptcoin is the given cryptocoin address (starts with some coins listed in CoinWarz.com that have working block explorers)

This isn't by any means accurate, it's a quick & dirty check, you have to resolve any conflicts by yourself.

The addresses are checked using base58Check native module (currently doesn't work on Windows, so it's shim'ed)

Usage

var dcc = require('detect-cryptocoin');
 
var detected = dcc([
    '1PskTzQjmzqB2boz67AXsv4C5YNWN4xmhu',
    'LW2kXiquqDu3GfpfBX2xNTSgjVmBPu6g3z',
    'PNKZEkDf9eBSNebu2CcxHaGuma6wHuZEBh',
    'ARKZ7uVE1YS19HC8jSq5xZGkr6YAzugWBv'
    ], ['BTC','LTC','PPC','XPM']);
    // You may narrow the function results by passing only the allowed/expected list as the second parameter.
    // everything that isn't in this list is ignored
 
console.log(detected);
 
// yields:
{
  'BTC': ['1PskTzQjmzqB2boz67AXsv4C5YNWN4xmhu'],
  'LTC': ['LW2kXiquqDu3GfpfBX2xNTSgjVmBPu6g3z'],
  'PPC': ['PNKZEkDf9eBSNebu2CcxHaGuma6wHuZEBh'],
  'XPM': ['ARKZ7uVE1YS19HC8jSq5xZGkr6YAzugWBv'],
  'conflicts': {},
  'invalids': []
}
 
// add more coins using:
 
dcc.coins.HKK = {
    name: 'HongKongKoin',
    starts: ['h']
};
 
// you may do an easy and fast check, using, [COIN SYMBOL].cryptocoinexplorer.com/q/checkaddress/[ADDRESS] for example
 
// If there's a conflict, you must check with your coin daemon if these addresses exists there, or using an API.
// They are valid, but they match multiple coins.
// Check the 'conflicts' member for conflicts:
