async function run() {
    const authResultHandler: HbWebSocketAuthResultHandler = async ({ success, msg, ws, service }) => {
        if (success) {
            service.sub('accounts.update#1') // subscribe to account updates after authentication success
        } else {
            console.error('auth error')
        }
    }

    const messageHandler: HbWebSocketMessageHandler = async ({ msg, ws, service }) => {
        // push event message
        if (msg.action == 'push') {
            if (msg.ch == 'accounts.update#1') {
                if (msg?.data?.changeType == 'deposit') {
