import { ContractEvents } from "azero-utils"

const ADDRESS = "5Cr8SncyKaM8C5V47hv3GvaZt8zAvnbrmafDL3zTXz5xQwZn";

// Connect to Aleph zero node
const wsProvider = new WsProvider("wss://ws.test.azero.dev");
const api = await ApiPromise.create({ provider: wsProvider });

// Instantiate contract and initialize contract events
const contract = new ContractPromise(api, metadata, ADDRESS);
let contractEvents = new ContractEvents(contract);

// Subscribe to new events
contractEvents.subscribeNewEvents(
    (event) => console.log("Event!:", event)
);
