Nansen
Users search tokens, wallets, or macro market sectors via the web interface, conversational AI agents, CLI commands (e.g., nansen research, nansen agent), or connected MCP tools.
What is Nansen?
Nansen brings together proprietary data labeling and smart money tracking. Human-readable tags applied to hundreds of millions of blockchain addresses to identify specific entities like funds, exchanges, market makers, early liquidity providers, and notable investors. Analytics dedicated to monitoring token holdings, net flows, historical trends, DEX trades, and perpetual trades (e.g., Hyperliquid integration) associated with labeled smart money profiles.
Its documented workflow includes: Users can sign up and access the platform via app.nansen.ai, with options for browser-based UI interaction, API keys, or programmatic terminal access via the official CLI (nansen-cli). Onboarding documentation outlines setting up Nansen via the Model Context Protocol (MCP) to connect AI clients like Claude or Cursor using environment variables (NANSEN-API-KEY). Users search tokens, wallets, or macro market sectors via the web interface, conversational AI agents, CLI commands (e.g., nansen research, nansen agent), or connected MCP tools.
The platform documentation describes wallet access this way: For automated workflows and micro-payment rails (like x402), the system allows users to create and fund a dedicated tool wallet (using assets such as USDC on Base/Solana or USDT0 on X Layer) that automatically signs transaction/payment headers.
