Nansen

Nansen is a blockchain analytics platform built around a database of more than 300 million labeled crypto wallets across 20+ chains. Labels cover categories such as Smart Money, funds, exchanges and OTC desks. The company was founded in 2020 and is headquartered in Singapore.

Tools Listed products include the labeled wallet dataset, the Nansen API and BigQuery access, Smart Alerts, and Counterparty Due Diligence. The wallet labels let a team see who sits behind an address and how it has behaved on-chain, which is useful when assessing a large counterparty.

Who uses it Stated target users are crypto funds, OTC desks, exchanges, and compliance and research teams. For payment and liquidity businesses the practical use is checking the on-chain profile and working capital of a client or trading partner before onboarding or extending credit.

Pricing Subscriptions start at $99 per month, with an enterprise API tier above that. Coverage is global. Limits on API calls and the scope of institutional features should be clarified with the vendor.
