litecoin-segwit-payments

Library to assist in payment processing on Litecoin. It first allows for generation of address according to the BIP44 standard.

Bitcoin-js is used for deterministic public and private keys. Please see the BIP32 standard for more information (BIP32).

Getting Started

npm install --save litecoin-segwit-payments

Create a new wallet (DON'T DO THIS ON PRODUCTION):

let segwitPayments = require('litecoin-segwit-payments')()
let keys = segwitPayments.generateNewKeys('really random entropy here')
console.log(keys.xpub)
console.log(keys.xprv)

Generate an segwit deposit address from a public seed (xpub). This is useful if you are a hot wallet and don't store the private key. You will need to keep track of which path node you are on (increasing INT):

let depositAddress = segwitPayments.bip44(keys.xpub, 1234) // for path m/49'/2'/0'/0/1234
console.log(depositAddress)

Get the private key for an address on a specific path:

let privateKey = segwitPayments.getPrivateKey(keys.xprv, 1234) // for path m/49'/2'/0'/0/1234

Get the public key from a private key:

let address = segwitPayments.privateToPublic(privateKey) // for path m/49'/2'/0'/0/1234
if(address === depositAddress){
  console.log('this library works')
} else {
  console.log('better not use this library')
}

Get the derived xpub key from a hardened private key:

let xpub = segwitPayments.getXpubFromXprv(xprv) // for path m/49'/2'/0'/0/1234

Note: It is suggested to generate your Private key offline with FAR more entropy than the default function, then use getXpubFromXprv. You have been warned!
