Built for airdrop, grants, and reward teams

Sybil-proof
your launch.

Free live protection for your dApp. Forensic audits for your wallet lists. Every wallet gets an allow / review / deny decision backed by on-chain evidence — not a black-box score.

The problem

Every wallet has a history.

A wallet that looks new to your campaign isn't new on-chain. Shared first funders, synchronized activity, identical contract sequences — coordinated farms leave trails. SybilScan reads them before they dilute your distribution and push real contributors aside.

Two products

Two ways in. One engine.

Shield verifies wallets live as they connect. The Audit turns any wallet list into decisions. Both run on the same scoring engine.

SybilScan Shield

One snippet on your dApp. Every wallet that connects is verified live — honeypot traps, automation signals, on-chain history. Real users in, farms flagged. No CSV ever.

No PII. No raw IP. Invisible to real users.

How the Audit works

From raw wallet list to eligibility-ready report. Shield users skip step one — captured wallets feed the same engine, no upload.

Step — 01

Evidence, not scores.

Real money rides on these decisions. Every one comes with reasons you can defend.

Decision packets

Every wallet gets an allow / review / deny decision with structured reasons your team can read, cite, and defend — not a black-box number.

Cluster review

Wallets with shared funders, synchronized activity, or identical contract sequences are grouped into clusters so you review 10 addresses, not 10,000.

Forensic evidence

Every reason cites specific on-chain evidence: tx hashes, funder addresses, cluster sizes, time windows. Plain English a non-technical reader can understand.

Export-ready reports

Download results as CSV or JSON the moment the scan completes. results.csv, decision_packets.json, ready to pipe into your existing workflow.

Pricing

Shield is free. Audits are pay-per-wallet — $20 minimum per job.
