Nansen

Nansen is a strong choice for active crypto traders and researchers who want wallet intelligence and Smart Money data alongside their trading workflow. Its biggest strength is the amount of context it puts around onchain activity, from labeled wallets and PnL to token flows and transaction behavior. The main drawback is that the platform can feel like a lot at first. The Free plan is useful for testing, but serious users will likely need Pro at $49 per month with annual billing or $69 per month on monthly billing. API usage also has its own credit system, so developers should consider both subscription access and API consumption when estimating their total cost.

Nansen is an onchain analytics and trading platform that helps crypto users track Smart Money, investigate wallets, research tokens and execute trades. It combines blockchain intelligence, labeled wallet data, AI-assisted research and trading tools in one interface. The platform's Wallet Profiler lets users investigate individual addresses, including their holdings, transactions, counterparties and PnL. Smart Money tools help users follow wallets that Nansen identifies as successful or influential based on trading performance and other onchain signals. Nansen has also expanded beyond analytics. Its current platform includes an AI-powered onchain analyst, in-app spot and perpetual trading, portfolio tracking, Smart Alerts and mobile access. Developers can use the Nansen API and MCP tools to work with onchain intelligence programmatically.
