Security Notice

We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.

Answers: "Are there wallets with suspicious trading patterns in this Polymarket market?"

# 1. Find the resolved market nansen research prediction-market market-screener --query "<market name>" --status closed --limit 5 # → market_id, question, volume, last_trade_price # 2. Get top winners (positive PnL) — paginate if needed, keep per_page <= 10 MID=<market_id> nansen research prediction-market pnl-by-market --market-id $MID --limit 10 # → address (proxy), owner_address (wallet), side_held, net_buy_cost_usd, total_pnl_usd # 3. For each top winner, run these three calls (use proxy address for PM, owner for profiler): PROXY=<address_from_pnl> nansen research prediction-market trades-by-address --address $PROXY --limit 100 # → market_id, market_question, side, price, size, usdc_value, taker_action, timestamp OWNER=<owner_address_from_pnl> nansen research profiler historical-balances --address $OWNER --chain polygon --days 365 --sort block_timestamp:asc --limit 100 # → block_timestamp, value_usd, token_symbol — first non-zero value_usd = wallet funding date nansen research profiler labels --address $OWNER --chain polygon # → label, category

For each winner, compute ROI = total_pnl_usd / net_buy_cost_usd * 100 (skip ROI flags if net_buy_cost_usd <= 0), then score (0–13). Within each tier group, apply only the highest matching flag:

Flag

Pts

Trigger

NEW_WALLET

First funded within 7 days of now

YOUNG_WALLET

First funded 8–28 days ago (skip if NEW_WALLET fires)

SINGLE_MARKET

trades-by-address shows only 1 distinct market_id

FEW_MARKETS

2–3 distinct market_ids (skip if SINGLE_MARKET fires)

EXTREME_ROI

ROI >= 500%

HIGH_ROI

ROI 200–499% (skip if EXTREME_ROI fires)

LATE_ENTRY

Any trade on this market at price >= 0.80

LARGE_POSITION

net_buy_cost_usd >= $10k

KNOWN_ENTITY

-2

Has Nansen labels

Flagged at score >= 3. High risk at >= 7. High-confidence suspicious pattern: NEW_WALLET + SINGLE_MARKET + EXTREME_ROI (score 9+).

If owner_address is invalid (e.g. "0x"), use the proxy address for profiler calls too. If historical-balances returns no records with value_usd > 0, the wallet may predate the 365-day window — treat wallet age as unknown and skip NEW_WALLET / YOUNG_WALLET flags. Pause ~1.5s between wallets to avoid rate limits. Skip wallets that error and continue scanning.
