Usage Guidance
This skill appears to do what it says: it runs the Nansen CLI against Polymarket-related Nansen endpoints and computes simple heuristics. Before installing, verify the npm package 'nansen-cli' is the official/expected package (check author, npm page, GitHub repo or published vendor) to avoid typosquat risks. Treat your NANSEN_API_KEY like a secret: consider using a key with minimal required permissions or a restricted/billing-limited account. Be aware the skill will make API calls that may consume your Nansen quota and could reveal which markets you scan. If you do not trust the package source, do not install; if you proceed, monitor API usage and limit the agent's ability to run the skill autonomously if you prefer.
Capability Analysis
Type: OpenClaw Skill
Name: nansen-polymarket-insider-scan
Version: 0.1.0
The skill is a legitimate tool designed to analyze Polymarket trading data for suspicious activity using the Nansen CLI. It follows a transparent logic of fetching market winners, checking wallet age, and calculating ROI to identify potential insider trading, with no evidence of data exfiltration, malicious execution, or prompt injection (SKILL.md).
Capability Assessment
Purpose & Capability
Name, description, declared binaries (nansen), primaryEnv (NANSEN_API_KEY) and the CLI commands in SKILL.md all align: the skill calls Nansen research endpoints to identify suspicious wallets on Polymarket. No unrelated services, binaries, or config paths are requested.
Instruction Scope
SKILL.md contains only Nansen CLI commands and local computations (ROI, scoring). It does not instruct reading unrelated files, other environment variables, or sending data to external endpoints beyond the Nansen API. It includes rate-limit pauses and error handling guidance.
Install Mechanism
Install uses an npm package (nansen-cli) that provides the nansen binary — this is a reasonable, expected mechanism for this functionality. Because the skill's source/homepage is unknown in the registry metadata, verify the npm package identity/maintainer before installing to avoid typosquat or malicious packages.
Credentials
Only a single credential (NANSEN_API_KEY) is required and is appropriate for the described API-driven scanning. No unrelated secrets or system credentials are requested.
Persistence & Privilege
The skill is not always-enabled, requests no system config paths, and does not ask to modify other skills or system-wide settings. It will run via normal agent invocation if allowed, which is expected.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install nansen-polymarket-insider-scan - After installation, invoke the skill by name or use
/nansen-polymarket-insider-scan - Provide required inputs per the skill's parameter spec and get structured output
Version History
v0.1.0
Initial release with Polymarket suspicious wallet scanner.
- Scans resolved Polymarket markets for wallets with suspicious trading patterns such as recent funding, high ROI, single-market focus, and late entries.
- Uses Nansen APIs to collect wallet activity, PnL, and profile information.
- Scores wallets based on flags like NEW_WALLET, SINGLE_MARKET, EXTREME_ROI, etc.; highlights as suspicious if score ≥ 3, high-risk at ≥ 7.
- Identifies high-confidence suspicious patterns, including combinations like NEW_WALLET + SINGLE_MARKET + EXTREME_ROI.
- Includes error handling and rate limit pacing to ensure reliable scanning.
