What it does
Nansen Polymarket Trader Profile is an agent skill from nansen-ai/nansen-cli. What is a Polymarket trader betting on? Trades by address, PnL breakdown, and market context. Use when analysing a specific Polymarket wallet.
Its SKILL.md is about 940 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Backend & APIs. It works with Polymarket. The licence is MIT.
When your agent uses it
- Analysing a specific Polymarket wallet
Example prompts
- “/nansen-polymarket-trader-profile”
Requirements
- A credential in NANSEN_API_KEY
- Pre-approved tools (allowed-tools): Bash(nansen:*)
What it can do on your machine
Read from SKILL.md and the folder at commit d097942. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
Bash(nansen:*)
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
NANSEN_API_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Nansen Polymarket Trader Profile loads about 940 tokens when it runs. Until then it costs about 44 tokens; SKILL.md has 365 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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.
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.

Polymarket Wallet Activity
Answers: "What is this Polymarket trader betting on? Are they profitable?"
Finding an active trader address: Source from trades-by-market (guarantees trade history) rather than top-holders (position holders may have no recorded trades):
# Step 1: find active traders from a market
nansen research pm trades-by-market --market-id <market_id> --limit 5
# → seller/buyer addresses with confirmed trade history — use one as ADDR belowADDR=<polymarket_address>
nansen research pm trades-by-address --address $ADDR --limit 20
# → timestamp, market_question, event_title, taker_action, side, size, price, usdc_value
nansen research pm pnl-by-address --address $ADDR --limit 20
# → question, event_title, side_held, net_buy_cost_usd, unrealized_value_usd, total_pnl_usd, market_resolvedNote: addresses sourced from top-holders may return empty trade history — use trades-by-market to find addresses with confirmed activity.
Look at PnL across resolved vs unresolved markets to gauge trader skill. Large positions in trending categories signal conviction.
