Farms hide behind hundreds of wallets. SybilScan finds what links them, then gives every wallet an allow, review, or deny decision you can defend.

Every wallet has a history.

A wallet that looks new to your campaign usually isn't new on-chain. Farms leave three trails. SybilScan follows all of them across your whole list.

Exhibit 01Funding

Shared funder

Dozens of wallets topped up by the same address, minutes apart.

Exhibit 02Timing

Synchronized activity

Wallets acting in the same 10-minute window, again and again.

Exhibit 03Behavior

Same contract sequence

The same first contracts, called in the same order.

Audit a wallet list

Self-serve. No sales call. Results in about 30 minutes.

Evidence, not scores.

Real money rides on these decisions. Each one ships with the reasons behind it and the on-chain facts to prove them, so you have an answer when your community asks why.

  1. A decision, not just a number

    Allow, review, or deny under the policy you pick, with a score and a confidence level.

  2. Grouped into clusters

    Linked wallets share a cluster ID, so you review 10 clusters instead of 10,000 wallets.

  3. Reasons with receipts

    Each reason names the funder, the time window, and the contracts involved, in plain English anyone on your team can follow.

  4. Ready to export

    Download CSV and JSON the moment the scan finishes and plug them into your claim flow.
