🚀 I built a plug-and-play mini app that lets users map their Farcaster ID (FID) to an Ethereum address onchain—in just a few clicks.

🧩 It’s fully reusable and embeddable, so if your app depends on an onchain FID mapping, you can:
    Detect unregistered users
    Seamlessly redirect them to the mini app to register
    Have them auto-return to your app once done—mini app → mini app, no friction

🔧 It’s also fully customizable via query parameters:
    img=<imgURL> → Show your branding or custom avatar
    redirect-url=<yourURL> → Auto-redirect back to your app
        Use <hash> inside the URL and it will be replaced with the actual tx hash
