class Mempool {
  private events: EventsService;

  constructor() {
    this.events = new EventsService({
      url: 'https://api.tzkt.io/v1/events',
      reconnect: true,
    });

  monitor = () => {
    this.events.operations({ types: ['transaction'] }).subscribe({ next: console.log });
  };
}

export const mempool = new Mempool();
