 * To use with BIP39, we recommend using [@scure/bip39](https://github.com/paulmillr/scure-bip39).

 * ```ts

 * import { wordlist } from '@scure/bip39/wordlists/english'
 * import { HDPrivKey } from '@aldea/core'
 *
 * const mnemonic = generateMnemonic(wordlist)
 * const seed = mnemonicToSeedSync(mnemonic)
 * const rootKey = HDPrivKey.fromSeed(seed)
 * const childKey = rootKey.derive('m/1/2/3')
