Cover image of Deep-dive into Push Snaps Features & Getting Started 🛠️

As we outlined in our announcement article — the Push Snap is a powerful tool that allows any wallet address and user to receive notifications directly in their MetaMask wallet. With the Push Snap installed, you can now seamlessly receive notifications powered by Push Protocol directly into your wallet, ensuring you never miss out on important updates from the channels you subscribe to.

By delivering notifications directly to your wallet address, we’re eliminating the need to log in to any other front-end separately to get those same notifications and alerts. By bringing all your notifications into one place, we’re saving you time, effort, and allowing you to more easily stay connected and informed.

Core Snap Features

The main features of version 1 of the Push Snap include:

  1. Notifications: Notifying users of all updates from the channels they opt-in to.
  2. Address Selection: Addition or removal of their desired addresses for notifications.
  3. Customization of Pop-Ups: Push Snap allows users to toggle popup notifications at their convenience.

Brief glance at the Push Snap’s working mechanism

  • The snap requests permission to run periodically every minute.
  • While running, it scouts for all new notifications/alerts received by your wallet
  • It then bundles all the notifications together and shows all of them in the form of a pop-up as well as in-app notification.
  • The Push Snap allows users to update their address for which they prefer to receive notifications.
  • The Push Snap also includes features to toggle the pop-up notifications as per the user’s choice.

Note: Currently, the Push Snap checks if more than 25 notifications are received per minute. If that’s the case, the Push Snap automatically notifies the user and snoozes the popups, which can always be turned back on from the dApp.
