Nansen Wallet Profiler

A straightforward wrapper around Nansen's wallet analysis API that lets you profile blockchain addresses without leaving the terminal. You get balance checks, PnL calculations, transaction history, counterparty analysis, and wallet labels across multiple chains. The trace command is clever for following money flows multi-hop, though it burns through API calls fast so you'll want to keep the width parameter low. The batch mode is handy when you're comparing cohorts of wallets. Perps trading data doesn't require a chain parameter, which makes sense. Most commands need both address and chain flags, and some endpoints like labels return everything regardless of pagination settings. If you're doing onchain forensics or tracking whale behavior, this beats clicking through Nansen's web UI.
