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

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 list as the second parameter.

console.log(detected);
/**

// add more coins using:

detected.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:

There's also a helper function, dcc.valid, it checks using Base58Check using Node.js Buffers (instead of Bignum/Bigint). It's not as performant, but it works in Windows.
