Social & Reputation
When to Use

Workflow
1. Lens Protocol (v3)
- Profile:
LensProfile NFT per user
- Publications: posts, comments, mirrors, quotes
- GraphQL via Lens API for feed queries
- Actions:
follow, collect, comment via Lens Client
Profile ID → Publications → Collect modules → Revenue split
2. Farcaster
- Hub API for casts, reactions, links
- Frames: Interactive embeds in casts (v2 SDK)
- Build frame with
fc:frame meta tags
- Handle
post_message callbacks for user actions
- Signer management for posting on behalf of users
3. Reputation Scores
Composite score from:
| Signal | Weight |
|---|
| Wallet age | 10% |
| DeFi participation (non-toxic) | 20% |
| Governance participation | 15% |
| NFT/ENS ownership | 10% |
| Social graph (mutual follows) | 15% |
| Attestations (EAS) | 20% |
| No sanctions/flags | 10% (binary gate) |
Use Gitcoin Passport, Talent Protocol, or custom scoring.
4. Prediction Markets
- Polymarket: CTF exchange on Polygon, USDC collateral
- Query market odds as probability signals
- Compliance: restrict US persons per CFTC guidance
5. DePIN (Emerging)
- Helium, Render, Filecoin network participation
- Token rewards for infrastructure provision
- Integrate device/wallet reputation for node operators
Privacy & Safety
- Never auto-post on behalf of user without confirmation
- Filter spam/low-reputation accounts in social feeds
- Prediction market integration requires jurisdiction check
