This is a template for integrating Privy and Biconomy into a NextJS project. Check out the deployed app here!
In this demo app, a user can login with their email, Google account, Discord account, Twitter account, or Apple account, and get a Privy embedded wallet. Once the user has logged in and created an embedded wallet, Biconomy will create a smart wallet for the user behind the scenes, which can then be used to incorporate gas sponsorship, batched transactions, and more into your app.
You can test this by logging into the app and attempting to mint an NFT with your smart wallet; it should cost you no gas!

This demonstrates how to wrap your React app with the PrivyProvider, and how to configure Privy's login methods, embedded wallets, etc.
This demonstrates how to initialize a Biconomy smart account from a Privy embedded wallet. In this example app, we store the user's Biconomy smart account in a React context to allow us to easily access it from other pages/components.
This demonstrates how to use Privy's login method to authenticate your users and create an embedded wallet for them.
This demonstrates how to use a Biconomy smart account's buildUserOp and sendUserOp methods to mint an ERC-721 NFT gaslessly.
