The open-source detection engine for airdrops, governance and DeFi farms. Built by people who got tired of watching $6B leak to bots.
Sybils through Nansen → 22% supply stolen
single farmer · 85 wallets · public extract
filter flags · thousands of false-positive complaints
filtered · zero public evidence per address
of distribution → exchanges within days
of airdropped tokens dump < 3 months
Wallets funded by same source within tight time-window. Confidence scales with proximity.
Density clustering over 10-dim feature vectors. Scripts surface as tight blobs.
Community detection on the tx graph. Isolated dense subgraphs = farms.
Hour/day entropy + autocorrelation. Humans are messy; bots are not.
Bridge events deterministically link wallet IDs across 8 chains.
LightGBM weighted by label-tier confidence. Honest holdout-only metrics.
Funded by 0xABC…123 → also funded 46 others within 1.0h
Pattern matches cluster B-17 with 94% similarity
Hour-of-day entropy 0.82 << human baseline (>2.5)
