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.
