What is Nansen?

Nansen is a leading on-chain blockchain analytics platform that enriches raw blockchain transaction data with millions of labeled wallet addresses. These labels—identifying wallets tied to smart money, venture capital, exchanges, or other significant actors—allow users to gain a deeper, contextual understanding of on-chain movements and actors.

At its core, Nansen empowers crypto investors, professional funds, DeFi protocols, NFT traders, and infrastructure teams to:

  • Discover opportunities by tracking profitable wallets (“smart money”) and spotting emerging trends.

  • Perform due diligence with intuitive dashboards and real-time alerts to defend against risks.

  • Make data-driven decisions using a rich set of analytics tools, such as no-code querying and wallet behavior insights.
