litecore-lib's Issues

xpub to get all address

Hi,
I need to get all the generated addresses for an xpub (or Ltub) extended public key. When I use the HDPublicKey.deriveChild(path, false), it is giving me this error:

message: 'Invalid argument: creating a hardened path requires an HDPrivateKey',
stack: 'Invalid argument: creating a hardened path requires an HDPrivateKey\n' +
'Error\n' +

Please help me to get the list of addresses from xpub or ltub extended public key.

How does litecore-lib set the value of fee, will it keep 0.001?

Transaction example

Transactions can have multiple utxos? How would we add those in?

const transaction = new litecore.Transaction();
    .from(utxo)
    .to(targetAddress, target)
    .to(changeAddress, change)
    .sign(privateKey);

Could someone please provide an example of a transaction with multiple inputs?

Can not convert private key to address

Hi, pls see the photo, I can not convert Private key to address.
I'm using: "litecore-lib": "^0.13.22",

And my codes:
var privateKey = "***"
var litecore = require('litecore-lib');
var address = new litecore.PrivateKey(privateKey).toAddress();
pls help me, thank you so much!

No matching version found for bitcore-lib-ltc@^8.25.12

Hi,
I tried to install the dependency of the bitcore-node (npm install), and I've got this error:

npm ERR! code ETARGET
npm ERR! notarget No matching version found for bitcore-lib-ltc@^8.25.12.
npm ERR! notarget In most cases you or one of your dependencies are requesting
npm ERR! notarget a package version that doesn't exist.
npm ERR! notarget
npm ERR! notarget It was specified as a dependency of 'crypto-wallet-core'
npm ERR! notarget

It seems that the crypto-wallet-core included in the bitcore-node's package.json is not able to find this specific version of the bitcore-libt-ltc.

Receive UTXOS to generate new transaction

How can I receive UTXOS data for some address to generate new dependent transaction?

When I do this for BTC I use:

    var Insight = require("bitcore-explorers").Insight;
    var insight = new Insight(network);
    insight.getUnspentUtxos(sourceAddress, function (error, utxos) {
        // ...
    }

TypeError: Number must be less than N

Hi. I am trying to sign a transaction and I am getting the error mentioned in the title. This is my code:

const bitcore = require('litecore-lib');
const Mnemonic = require('litecore-mnemonic');

const words = 'something something ...';
const code = new Mnemonic(words);
const hdPrivateKey = code.toHDPrivateKey('password', "livenet");
const derivationPath = hdPrivateKey
  .derive(44, true)
  .derive(2, true)
  .derive(0, true)
  .derive(0);
const utxo = {
  ...
}
const originAddress = '..';
const destinationAddress = ',,';
const privateKey = derivationPath.derive(0).privateKey;

const tx = new bitcore.Transaction()
  .from(utxo)
  .to(destinationAddress, 0.001 * 100000000)
  .change(originAddress);

tx.sign(privateKey);

And the complete stack trace is:

Is it stable and generating SegWit addresses?

Anyone can confirm if litecore-lib is stable and generates segwit address as well? If not what could be done to reach that stability and feature?

What is network value of REGTEST?

Hello, I have a question about network parameters.

I have used below values for litecoin testnet

{
  messagePrefix: '\x19Litecoin Signed Message:\n',
  bech32: 'tltc',
  bip32: {
    public: 0x0436f6e1,
    private: 0x0436ef7d,
  },
  pubKeyHash: 0x6f,
  scriptHash: 0x3a,
  wif: 0xef,
}

And I'm trying to find REGTEST values, but in https://github.com/litecoin-project/litecore-lib/blob/segwit/lib/networks.js,
It uses almost same values with TESTNET.

What is correct value of REGTEST?

HDPrivateKey derivation: version argument is not a buffer

The following code fails:

const HDPrivateKey = require('litecore-lib').HDPrivateKey;
