🌟 FanTag

Decentralized identity for creators & fans using ENS subnames + EFP

---

✨ Short Description

FanTag lets creators register ENS-based fan communities, and allows fans to claim subnames tied to their favorite creators. Powered by ENS subnames + Ethereum Follow Protocol, it builds verifiable, portable identities for Web3 culture.

---

❌ Problem

• Fans and creators rely on centralized platforms like Instagram or TikTok where usernames are siloed.
• No portable identity that works across platforms.
• Communities lack verifiable ownership and provenance.

---

✅ Solution

• Creators register a .fantoken.eth domain.
• Fans claim subnames like alice.creator.fantoken.eth as their digital fan identity.
• Profiles are enriched with EFP social graph data + ENS text records.
• One-click wallet login via Scaffold-ETH 2 UI.
• Offchain resolution with Durin ensures smooth UX and faster lookups.

---

🛠️ How It’s Made

• Smart Contracts

  • Custom Registrar contract for creator + fan subname registration.

• ENS + Durin

  • ENS Registry for managing/issuing subnames.
  • Durin used for offchain resolution.

• Frontend

  • Built with Next.js, wagmi, and RainbowKit.
  • Ethereum Identity Kit (EIK) for seamless EFP integration.

• Dev Tools

  • Hardhat for contract deployment/testing.
  • Scaffold-ETH 2 base stack for fast iteration.

• UX Choices

  • One-click creator/fan registration.
  • Auto-linked ENS + EFP profiles.
  • Offchain ENS lookups for responsiveness.
