altcoin-address

Functions for working with altcoin addresses, forked from DefunctZombie.

API

validate (address [, type])

returns true if the address (string) is a valid altcoin address for the type specified

if no options are specified it defaults to bitcoin

get_address_type (address)

returns address type if valid base58 address, otherwise null

Address types

• Bitcoin/BTC (bitcoin)
• Litecoin/LTC (litecoin)
• Peercoin/PPCoin/PPC (peercoin)
• Dogecoin/DOGE (dogecoin)
• BeaverCoin/BVC (beavercoin)
• Freicoin/FRC (freicoin)
• Protoshares/PTS (protoshares)
• Megacoin/MEC (megacoin)
• Primecoin/XPM (primecoin)
• Auroracoin/AUR (auroracoin)
• Namecoin/NMC (namecoin)

I intend to update this to include more currencies in the future. If you would like a new currency added quickly please send a pull request including tests.

This will work for both BIP-0016 P2SH addresses and regular addresses.

To check the validity of a testnet address for any of the listed coins just append 'Testnet'

Example

var altcoin = require('altcoin-address');

var valid = altcoin.validate('1KFzzGtDdnq5hrwxXGjwVnKzRbvf8WVxck', 'bitcoin');
if(valid)
	console.log('This is a valid address');
else
	console.log('Address INVALID');


//This should return that 'This is a valid address'

var altcoin = require('altcoin-address');

var valid = altcoin.validate('1KFzzGtDdnq5hrwxXGjwVnKzRbvf8WVxck', 'litecoinTestnet');
if(valid)
      console.log('This is a valid address');
else
      console.log('Address INVALID');


//As this is a invalid litecoin address response will be 'Address INVALID'
