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.
