HD & Mnemonic implementation for lumos.

Usage

Create a new HD wallet.

const { mnemonic, ExtendedPrivateKey, Keystore } = require("@ckb-lumos/hd")
const m = mnemonic.generateMnemonic()
const seed = mnemonic.mnemonicToSeedSync(m)
const extendedPrivateKey = ExtendedPrivateKey.fromSeed(seed)
const keystore = Keystore.create(extendedPrivateKey, "Your password")
// save keystore file
keystore.save("you path, only dir")

// load keystore file
const keystore = Keystore.load("you file path, with file name")
Copy

XPub support.

const { XPubStore } = require("@ckb-lumos/hd")

// load from xpub file.
const xpub = XPubStore.load("you path")

// to AccountExtendedPublicKey
const accountExtendedPublicKey = xpub.toAccountExtendedPublicKey()

// save xpub file.
xpub.save("your path")
Copy

Browsers

This package enforces key management by importing buffer, stream, crypto, fs and path packages, which are not available in browser environment. If you want to use '@lumos/hd' in your front-end project, please include polyfill to your project module bundle. Here is a webpack example:

resolve: {
  ...
  fallback: {
    fs: false,
    buffer: require.resolve('buffer/'),
    stream: require.resolve('stream-browserify'),
    path: require.resolve('path-browserify'),
    crypto: require.resolve('crypto-browserify'),
  },
  plugins: [
    new webpack.ProvidePlugin({
      process: 'process/browser',
      Buffer: ['buffer', 'Buffer'],
    }),
  ],
}
Copy

You'll need to install buffer, stream-browserify, path-browserify and crypto-browserify also.
