PassportGlobal

PassportGlobal is an mobile web app that lets users create a digital passport on-chain. The digital passport follows the ERC721 standard, so it can also be displayed as an NFT. The main functionality of this project that you can receive stamps when visiting a city. This is how it works:

1. User creates a passport which is minted as an NFT .
2. User verifies with worldcoin to get full access of application . For eg . Granting stamps to other users
3. The visitor requests a stamp and receives a QR-Code.
4. The attester user scans the QR-Code from his phone and can verify that the visitor has been to said city or Country
5. Once the QR code is successfully scanned , The User will recieve the country /City Stamp via EAS attestations

However, the attester must be verified with Worldcoin ID.

All of this is visualized in a pretty mobile-compatible UI. The Video is been made in Desktop UI mode where as the application looks best in mobile UI view ie. 390 x 840 ..

Passport Global is bootstrapped with the optimism starter kit: The frontend is built with react/vite + wagmi/viem. Styling is done with tailwind and daisy UI. To connect the wallet, we have used Rainbowkit.

We also have a location search backed by the Google Maps API's. The backend is written in foundry, a solidity framework. So , We use Worldcoin to Verify Users to Grant Stamps and get a Verified Badge. We used Figma and Canva for Logos and UI designs .
