Rank Polymarket copytrading leaders using Nansen as a data layer — pnl-by-market for the target market is the primary signal, address-summary/pnl-by-address is a secondary, credit-guarded refinement. Includes an experimental (dry-run only) live insider scan. Use when Simmer needs to re-rank or filter a leader list before executing copytrading rebalances on a specific Polymarket market.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Nansen Copytrader Overlay Nansen is a **data layer only** in this skill: PM PnL quality overlay + address-summary/wallet quality. It is **not** smart-money-labeled copytrading — Nansen's smart-money labels are not Polymarket-specific, and no code path here calls the labels endpoint at all. ## When to use this skill Simmer is about to execute a copytrading rebalance into a specific Polymarket market and has a candidate leader list (wallets + an existing `wallet_score`). Use this skill to re-rank that list using Nansen's Polymarket-specific PnL data before Simmer acts on it. Do **not** use this skill to: - Generate smart-money labels or entity classifications (out of scope — see framing above). - Place trades. Every function and CLI command here is signal-only; the caller (Simmer's execution wrapper) owns the actual `--live` gate. ## Core signal: pnl-by-market first The primary ranking signal is `pnl_by_market(market_id)` — who is actually profitable **in the target market**, not a wallet's broad trading history. `pnl_by_address` / `trades_by_address` (broad history) and `address_summary` (cheap wallet-quality pre-filter) are secondary — …

How to install
mdr add spartanlabsxyz/simmer-sdk/nansen-copytrader-overlay@sha256:29a5523950b68b63The line at the top of this page pins the label v0.2.2, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
