Privy PWA Demo

This is a template progressive web app (PWA) built with Privy, Viem, NextPWA, and TailwindCSS. All transactions are sent on the Base Goerli testnet.

You can see the deployed version at pwa.privy.io.

Setup

First, clone this repo:

npx degit privy-io/create-privy-pwa my-pwa-project
cd my-pwa-project

Next, install dependencies, (includes @privy-io/react-auth, viem, and next-pwa:)

npm i

Next, create your own env file by running

cp .env.example.local .env.local

and add your Privy App ID:

NEXT_PUBLIC_PRIVY_APP_ID=insert-your-app-id

Lastly, run

npm run dev

visit http://localhost:3004 in your browser to see the PWA in action!

For testing development on mobile, we recommend using ngrok (guide), since privy makes use of crypto.subtle which requires a secure context (https)
