Social & Reputation

When to Use

• Querying Lens Protocol profiles and publications
• Reading/posting Farcaster casts and Frames
• Building reputation scores from on-chain activity
• Integrating prediction markets (Polymarket, Omen)
• Social trading signals and copy-trading filters

Prerequisites

• MCP: blockchain-rpc-server, nft-metadata-server
• Skills: skill-10 (identity), skill-07 (analytics)

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
