  • Name: Nansen
  • URL: https://nansen.ai/
  • Category: onchain analytics / labeled-wallet intelligence / agentic trading and API platform
  • Summary: Nansen is an onchain intelligence platform that now combines wallet-label analytics with direct execution, API access, AI-agent interfaces, and MCP integrations. Its official site and docs show a product direction that goes beyond dashboards: Nansen increasingly presents itself as an agentic onchain app where users can research market activity, profile wallets and portfolios, and execute trades from the same surface.
  • What it does:
    • Labels hundreds of millions of blockchain addresses and exposes wallet- and entity-level intelligence through its web app and API
    • Provides Smart Money, portfolio, profiler, token-screening, Hyperliquid, and prediction-market data surfaces through a single developer API
    • Supports direct execution and routing from the Nansen product experience, including swap/trade flows and wallet-based portfolio management
    • Exposes AI-facing integration paths via an agent setup flow, streamed research-agent API endpoints, and a hosted MCP server for AI clients
    • Maintains public engineering surfaces through its GitHub organization, including ETL table definitions, a CLI, MCP packaging, and OpenClaw/Claude Code skills
  • Key claims:
    • The official site now describes Nansen as “The first truly agentic onchain app” and says users can “research, analyze, and execute, all in one loop”
    • The homepage claims Nansen is powered by “500M+ labelled addresses” and positions Smart Money tracking as a core product differentiator
    • The API docs say Nansen offers access to “high-quality onchain data and advanced blockchain analytics” with “hundreds of millions” of proprietary labels across multiple chains
    • The docs expose dedicated API categories for Smart Money, Profiler, Token Screener, Portfolio, Hyperliquid, Points, Prediction Markets, and Agent endpoints
    • The agent docs publish both a user-facing setup flow and streamed fast / expert research-agent endpoints backed by onchain data
    • The MCP docs document a hosted MCP endpoint plus integration guidance for Claude Desktop, Claude Code, Cursor, and other MCP clients
    • Nansen Academy docs show that the product now supports “Agentic Trading” alongside standard swap flows, routing across Jupiter, OKX, and LI.FI from within Nansen
    • The public GitHub organization reinforces the platform view, with repos for ETL table definitions, nansen-cli, nansen-skills, and MCP-related packaging
  • Whitepaper: No classic standalone whitepaper or litepaper was found during this pass. The strongest primary materials were Nansen’s official site, API/docs portal, agent and MCP documentation, academy/help materials for trading flows, and public GitHub organization; see ../whitepapers/nansen-primary-sources-2026-04-26.md.
