OVER TIME

All charts share the 7d window selected here. Every series is also served as JSON at /api/v1/services/nansen/price, /scores, /volume and /buyers. On-chain volume and distinct buyers are measured over the service's settlement address and are a conservative undercount (only settlements that reach a measured facilitator are counted).
