Solution

Web-app: We used Next.js, TypeScript, Tailwind CSS, Mapbox for navigation and maps and an express.js backend. Blockchain: We built on the Flow blockchain using Cadence smart contracts, the Flow Client Library (FCL), and the Flow emulator. We also used Privy for authentication.We connected the blockchain and our web-app via a Node.js REST API. Everything was decentralized and stored on-chain — smart contracts, NFTs, their metadata, and NFT images — so no traditional database was needed. Privy enabled easy wallet-based authentication, with automatic wallet generation for users. We used diverses API's to automatically find relevant cities' places (in France only, using gov. API's)
