About Nansen
Nansen is an AI-powered blockchain analytics platform that provides actionable insights by enriching on-chain data with wallet labels. Founded by Alex Svanevik, Evgeny Medvedev, and Lars Bakke Krogvig in 2019, Nansen pioneered the concept of 'smart money' tracking—identifying and following wallets with proven track records.
The platform has labeled over 500 million wallets across multiple chains, categorizing them as smart money, funds, exchanges, whales, and more. This labeling enables users to see not just what's happening on-chain, but who is behind the activity. Nansen's products include portfolio tracking, token analytics, NFT analytics, and real-time alerts.
Nansen serves both retail and institutional users, with features ranging from simple smart money tracking to advanced API access and custom dashboards. The platform's AI capabilities help surface insights from the massive amount of on-chain data, making it easier to identify opportunities and risks.

Frequently Asked Questions
Nansen is an on-chain analytics platform that labels blockchain wallets to show who is behind transactions. Instead of seeing anonymous addresses, you see 'Smart Money', 'Fund', 'Exchange', etc. This reveals patterns like smart money accumulating a token before it pumps, or whales moving funds to exchanges before selling. It turns raw blockchain data into actionable intelligence.
Smart Money refers to wallets with proven profitable track records. Nansen identifies them through historical analysis—wallets that consistently bought tokens early before price increases, made profitable DeFi moves, or belong to known successful traders/funds. These labels are constantly updated based on ongoing performance.
Nansen offers a free tier with limited features. Full access requires paid plans: Lite (~$100/month) for basic features, Standard (~$150/month) for full smart money tracking, and VIP/Enterprise tiers for advanced API access and custom solutions. Plans include different levels of data access, alerts, and historical data.
They serve different purposes. Dune is a query platform where you write SQL to analyze raw data—flexible but requires SQL skills. Nansen provides pre-built analytics with wallet labels—ready-to-use insights without querying. Many serious researchers use both: Dune for custom analysis, Nansen for smart money tracking and alerts.
Yes. Nansen's portfolio feature lets you connect wallets or enter addresses to track holdings, P&L, and transaction history. You can see how your performance compares to smart money and get alerts when wallets you follow make moves. This is available across all supported chains.
