Getting Started

A Next.js starter kit with Sign-in With Ethereum + ethers.js + iron-session

Note: This is a barebones, fairly unopinionated implementation of Sign-in with Ethereum authentication that requires the MetaMask extension. It will not work without it. Additional wallets are not featured; however, you may use Web3Modal or other similar libraries to provide additional features.

First, install the dependencies:

npm i
# or
yarn add

Run the development server:

npm run dev
# or
yarn dev

Open http://localhost:3000 with your browser to see the result.

API routes

API routes can be accessed on:

• http://localhost:3000/api/nonce. This endpoint can be edited in pages/api/nonce.js.
• http://localhost:3000/api/verify. This endpoint can be edited in pages/api/verify.js.

The pages/api directory is mapped to /api/*. Files in this directory are treated as API routes instead of React pages.
