The Quai HD wallet is a BIP44-compliant hierarchical deterministic wallet used for managing a set of addresses in the Quai ledger. This is the easiest way to manage the interaction of managing accounts and addresses on the Quai network, however, if your use case requires a single address Quai address, you can use the Wallet class. The Quai HD wallet supports:
  • Adding accounts to the wallet heierchy
  • Generating addresses for a specific account in any Zone
  • Signing and sending transactions for any address in the wallet
  • Signing and verifying EIP1193 typed data for any address in the wallet.
  • Serializing the wallet to JSON and deserializing it back to a wallet instance.

​
Example

import { QuaiHDWallet, Zone } from 'quais';

const wallet = new QuaiHDWallet();
const cyrpus1Address = await wallet.getNextAddress(0, Zone.Cyrpus1); // get the first address in the Cyrpus1 zone
await wallet.sendTransaction({ from: address, to: '0x...', value: 100 }); // send a transaction
const serializedWallet = wallet.serialize(); // serialize current (account/address) state of the wallet
.
.
.
const deserializedWallet = QuaiHDWallet.deserialize(serializedWallet); // create a new wallet instance from the serialized data
