HD & Mnemonic implementation for lumos.
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")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")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'],
}),
],
}You'll need to install buffer, stream-browserify, path-browserify and crypto-browserify also.
