For more high level overview on what wallets are available in the SDK, see the Wallet fundamentals page.
The QiHDWallet class provides additional low-level functionality on top of the base Wallet class, allowing for more granular control and wallet management.

​
Initialize a Quai HD Wallet

You can initialize a Quai HD wallet by creating a new instance from a mnemonic:
const quais = require('quais')

// seed phrase
const phrase = 'pill tomorrow foster begin walnut borrow virtual kick shift mutual shoe scatter'

// initialize HD wallet from mnemonic
const mnemonic = quais.Mnemonic.fromPhrase(phrase)
const quaiWallet = quais.QuaiHDWallet.fromMnemonic(mnemonic)
It is highly recommended to import secret phrases securely from environment variables or files.

​
Derive Addresses

Quai HD wallets allow for derivation of multiple accounts, addresses, and specific zones from a single mnemonic as specified by BIP-32.
// derive new address for account '0' in 'Cyprus1' zone
const addressInfo1 = await quaiWallet.getNextAddress(0, quais.Zone.Cyprus1)

// derive new address for account '1' in 'Cyrpus2' zone
const addressInfo2 = await quaiWallet.getNextAddress(1, quais.Zone.Cyprus2)
The HD Wallet also provides a number of methods to return data for derived addresses by certain filters:
// get address info for account '0' new address '1'
const addressInfo = quaiWallet.getAddressInfo(addressInfo1.address)

// get all addresses for account '0' in 'Cyprus1' zone
const cyprus1addressInfo = quaiWallet.getAddressesForZone(quais.Zone.Cyprus1)

// get all addresses for account '0'
const account0Addresses = quaiWallet.getAddressesForAccount(0)

​
Storage and Transmission

Wallet storage and transmission can be securely done using a serialized representation of the wallet. The HD wallet provides functionality for both serializing and deserializing the wallet.
// serialize current (account/address) state of the wallet
const serializedWallet = quaiWallet.serialize()

// deserialize wallet from serialized data
const deserializedWallet = quais.QuaiHDWallet.deserialize(serializedWallet)
