Nansen Wallet Clustering
This connects Claude to Nansen's wallet attribution API for tracking ownership and relationships across blockchain addresses. You'd use it when investigating funding sources, comparing wallets for shared counterparties, or mapping out governance voter clusters. It chains together profiler commands to build relationship graphs, though the prompt warns you to ask before expanding beyond the seed address since multi-hop traces burn through API credits fast. The clustering logic is opinionated about what counts as high confidence (first funder, shared Safe signers) versus noise (single ENS lookups). Works across Ethereum, Solana, and L2s. Honestly most useful if you already know Nansen's data model, since you're basically scripting their CLI.

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.
