Nansen

Nansen is a blockchain analytics platform headquartered in Singapore that enriches on-chain data with a database of over 500 million labeled wallet addresses. The platform allows crypto investors and traders to track wallet activity, monitor so-called Smart Money wallets, and analyze token flows across multiple blockchain networks in real time.

Founded in 2019 by Alex Svanevik, Lars Krogvig, and Evgeny Medvedev, Nansen serves both retail and institutional participants in the crypto market. Its core offering combines on-chain research tools, real-time portfolio monitoring with profit and loss tracking, and trade execution for spot and perpetual futures markets. The platform also provides alerts, dashboards, and a conversational AI interface for agentic trading strategies.

Nansen supports several networks including Solana and Hyperliquid, and is available as a web application and mobile app. A free tier is offered for basic Solana on-chain exploration, with paid plans providing access to deeper analytics and cross-chain data.
