Description
How has a wallet's portfolio changed over time? Historical balances, current snapshot, and per-token PnL.
Usage Guidance
This skill appears to do what it says: run the Nansen CLI against a wallet address using your Nansen API key. Before installing, verify you trust the nansen-cli npm package and its publisher (review the package repo and recent release history). Be aware that any wallet addresses you pass will be sent to Nansen's service, and your NANSEN_API_KEY will be used by the CLI — limit the key's scope if possible and rotate it if you suspect compromise. Never provide private keys or sensitive secrets; only provide the API key required by Nansen. If you have high security requirements, consider running the npm install in an isolated environment (container/VM) and inspect the package contents before use.
Capability Analysis
Type: OpenClaw Skill
Name: nansen-portfolio-tracker
Version: 0.1.0
The skill is a legitimate portfolio tracking tool that interfaces with the Nansen crypto analytics platform. It uses the 'nansen-cli' (installed via npm) to fetch historical balances and PnL data, requiring a standard NANSEN_API_KEY environment variable. No signs of data exfiltration, malicious execution, or prompt injection were found in SKILL.md or _meta.json.
Capability Assessment
Purpose & Capability
The skill is a Nansen portfolio tracker and only requires the 'nansen' CLI and NANSEN_API_KEY. These requirements reasonably match the described functionality (historical balances, snapshot, per-token PnL).
Instruction Scope
SKILL.md instructs only to run nansen CLI commands against a supplied wallet address and chain. This will transmit the wallet address/queries to Nansen's service (expected for this purpose). No unrelated files, system paths, or extraneous environment variables are referenced.
Install Mechanism
Install uses the npm package 'nansen-cli' to provide the 'nansen' binary. That is coherent for this skill but carries the normal npm risk surface (installing third-party code).
Credentials
Only NANSEN_API_KEY is required and declared as the primary credential. That is proportional to calling Nansen's API via their CLI.
Persistence & Privilege
The skill is not always-enabled and does not request elevated platform privileges or modify other skills. Autonomous invocation is allowed (platform default) but not exceptional here.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install nansen-portfolio-tracker - After installation, invoke the skill by name or use
/nansen-portfolio-tracker - Provide required inputs per the skill's parameter spec and get structured output
