## 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.


# Wallet Attribution

**Answers:** "Who controls this wallet? Are these wallets related?"

Chain: `0x` → `--chain ethereum` (also base, arbitrum, optimism, polygon). Base58 → `--chain solana`.

```bash
ADDR=<address> CHAIN=<ethereum|solana|base|...>  # detect from address format above
# 1. Identity
nansen research profiler labels --address $ADDR --chain $CHAIN
# 2. Related wallets (paginate with --page N)
nansen research profiler related-wallets --address $ADDR --chain $CHAIN
# 3. Counterparties (paginate with --page N; widen with --days 365 if empty)
nansen research profiler counterparties --address $ADDR --chain $CHAIN --days 90
# 3b. Once a cluster is confirmed: counterparties for up to 10 of its wallets in one call
#     (max --days 90; one ecosystem per request — EVM and Solana cannot be mixed). Rows are
#     contiguous per-wallet blocks ordered by wallet address: raise --limit and page with
#     --page N to reach later wallets.
nansen research profiler counterparties-batch --addresses "addr1,addr2" --chain $CHAIN --days 90 --limit 50
# 4. Batch profile cluster
nansen research profiler batch --addresses "addr1,addr2" --chain $CHAIN --include labels,balance,pnl
# 5. Compare pairs → shared_counterparties, shared_tokens, balances
nansen research profiler compare --addresses "addr1,addr2" --chain $CHAIN
# 6. Historical balances (fingerprint drained wallets)
nansen research profiler historical-balances --address $ADDR --chain $CHAIN --days 90
# 7. Multi-hop trace (credit-heavy — keep --width ≤3)
nansen research profiler trace --address $ADDR --chain $CHAIN --depth 2 --width 3
```

**Expansion:** Run steps 1-2 on seed. For each new address found, ask the human before querying. Reserve step 3 for seed only.
**Stop when:** known protocol/CEX · Low confidence · already visited · cluster > 10 wallets.
**Confidence:** High = first funder / shared Safe signers / same CEX deposit. Medium = coordinated movements / related-wallets + label match. Exclude = ENS only, single CEX withdrawal, single deployer.
