Data Sources

What sources do you use?

Sources are ranked by confidence level (highest to lowest):

🟢 High Confidence

  • Manual — Manually verified entries
  • Tally — On-chain governance data
  • Friend.tech — Platform-verified Twitter links
  • Uniswap Sybil — Verified address-to-Twitter mappings
  • Clusters.xyz — Named multi-wallet clusters

🟡 Medium Confidence

  • Farcaster — Social graph connections
  • Blurt — Blurt platform data
  • Friend.tech Heuristic — Inferred from Friend.tech data

🟠 Lower Confidence

  • Galxe — Platform usernames (NOT verified Twitter)
  • Layer3 — Platform usernames (NOT verified Twitter)
  • Legacy Twitter — Older, unverified mappings
⚠ Important: Galxe and Layer3 usernames are self-chosen platform names, NOT verified Twitter handles. Always check the source field in API responses.

What are clusters?

Clusters group addresses controlled by the same entity. We detect them via:

  • clusters.xyz — Named clusters with multiple verified wallets
  • shared_twitter — Multiple addresses linked to the same Twitter handle

The API response includes cluster info with fields like transitive, identified, and truncated.

Is the data accurate?

  • ✓ Governance and Sybil data = highly reliable
  • ✓ Manual entries = verified
  • ⚠ Platform usernames (Galxe, Layer3) = may not match Twitter
  • ⚠ Handles can change over time

What do you log?

IP, timestamp, queries — deleted after 12 hours. No long-term tracking.
