# nansen-wallet-deep-dive

The skill runs a wallet through labels, balance, PnL, transactions, perp positions and counterparties via the Nansen CLI. Useful when you need to know who is behind an address.

## What it does

One address, one pass: labels and categories such as "Smart Trader" or "Fund", then holdings with price and USD value, a 30-day PnL summary with win rate and top-5 tokens, recent transactions, perp positions, and counterparties with volume in both directions. All of it wraps `nansen research profiler` commands.

Before the first call you need a selected API key or a saved browser session, because the skill asks you to run `nansen auth status` first. Cached metadata does not prove the credential works, so anonymous selection or an auth failure stops the run. `NANSEN_API_KEY` overrides the saved session.

Every call can cost money, loops included: keys and browser sessions share the same automatic x402 payment behaviour, and a supported HTTP 402 challenge can spend from the configured wallet within your limits. Auth and session-renewal failures never trigger payment. Perp positions come from Hyperliquid and return empty when the wallet has no open perps.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add nansen-ai/nansen-cli --skill nansen-wallet-deep-dive -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/nansen-wallet-deep-dive/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/nansen-wallet-deep-dive/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add nansen-ai/nansen-cli --skill nansen-wallet-deep-dive -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/nansen-wallet-deep-dive/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add nansen-ai/nansen-cli --skill nansen-wallet-deep-dive -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/nansen-wallet-deep-dive/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

gemini skills install https://github.com/nansen-ai/nansen-cli --path skills/nansen-wallet-deep-dive
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/nansen-wallet-deep-dive/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add nansen-ai/nansen-cli --skill nansen-wallet-deep-dive -a opencode
```

### Claude.ai

**Claude.ai**

## When to use it
- find out who is behind an address from labels and categories
- see holdings with price and USD value per token
- check PnL over a period and the share of winning trades
- review recent transactions and their volumes
- list counterparties and how much volume moved with each

## Example prompts
- research wallet 0x... on ethereum: labels, balance and 30-day PnL
- show the last 20 transactions for this address
- does this wallet have any open perp positions

## Authentication

Browser login requests `nansen:api` for API-key-equivalent account API permissions; existing OAuth/MCP `nansen:read` semantics and separate wallet authorization are unchanged.

Before any research command or loop, require an explicitly selected API key or saved browser session. Run `nansen auth status` first. Its cached/unverified metadata does not prove credential validity or unlocked storage. Cached access-token expiry alone does not mean the session is unusable: the CLI normally renews a selected session automatically during an already-authorized research task, without another consent request or a separate account check. Stop on anonymous selection, invalid authentication state, blocked or uncertain renewal/cleanup, or an actual authentication failure, including rejected or expired refresh authority. Follow the CLI error guidance; use the free `nansen account` check when troubleshooting calls for it. Do not unset a failed key, erase a session or switch to anonymous access to retry.

Use `nansen login` for fresh browser approval within the documented platform scope, or configure a conventional API key. `NANSEN_API_KEY` overrides the saved session. OpenClaw's optional `primaryEnv` mapping preserves configured API-key injection; it is not a required-key gate or proof of authentication. Normal credits and entitlements apply. Login does not purchase credits. Browser login is available in CLI 2.0.0 within the [macOS arm64 preview scope](https://github.com/nansen-ai/nansen-cli/blob/main/docs/browser-login.md#preview-platform-scope).

API keys and browser sessions use the same automatic x402 payment behavior: a supported HTTP 402 challenge can spend funds from the configured wallet under existing wallet authorization, payment policy and spending limits. Each call, including calls in loops, can incur a payment. Authentication, authorization and session-renewal failures never trigger payment; login verification and `nansen account` never pay automatically. Anonymous x402 remains available as a separate paid workflow requiring explicit user intent and payment setup. Do not run this research workflow anonymously or switch to anonymous access after authentication fails.
