EthBoy - EPNS Push Notifications for OpenSea

Screenshots

Problem Statement

EthBoy is here to help you stay on top of all the action in NFTs without having to be glued to your screens. Simply connect to the EthBoy web app and set customize the push notifications for changes in the NFT marketplace. And you can receive these notifications in the many EPNS tools: the mobile app, browser extension, or right on the EthBoy web app.

Solution

EthBoy uses WalletConnect to obtain the wallet address of the user. The user can then choose different NFT collections and events from OpenSea's streaming API to be alerted on. The EthBoy server listens for updates and when they come in, it uses the EPNS SDK to send push notifications to all users who subscribed.
