This is a demo project for the paper-embedded wallet service. The wrong way to use the SDK will cause the error when the user cancels the log in the first time and try to log in with the modal again. This project uses Next.js. Put your paper key into the .env.local like below

NEXT_PUBLIC_KEY=MY_KEY

Then, run the development server:

npm run dev
# or
yarn dev
# or
pnpm dev

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

The two buttons indicate the two methods. See source code(pages/index.tsx) for more information.
