Nansen is a blockchain analytics platform that enriches on-chain data with wallet labels to help crypto investors make informed decisions. It supports over 20 blockchains, including Ethereum, Solana, and Optimism, and processes petabytes of data daily using AI algorithms. The platform offers real-time dashboards, alerts, and research to track market trends and portfolio performance.

Key features include Smart Alerts, which notify users of significant on-chain events, like large token transfers, and Smart Segments, which allow custom wallet grouping for targeted tracking. Nansen Query provides API access for programmatic data analysis, while the Research Portal delivers expert-driven market insights. The Portfolio Tracker monitors holdings across multiple chains. Nansen 2, the latest version, improves speed and dashboard customization.

Compared to competitors like Dune Analytics and Glassnode, Nansen excels in wallet labeling and real-time insights. However, its pricing is higher, targeting professional investors rather than retail users. Chainalysis focuses more on compliance, making Nansen better suited for investment strategies.

Some users appreciate the platform’s depth, with tools like Gas Tracker for Ethereum activity, but others find the interface complex for beginners. Recent X posts highlight fast data access in Nansen 2, though some users report billing issues, such as unauthorized charges after cancellation. Public blockchain data means privacy risks, like exposed ENS names, may surprise new users.

For best results, use Smart Alerts to monitor key tokens, explore the Research Portal for free reports, and leverage Smart Segments to track specific market players. Test the free tier to assess its value before upgrading.
