risk clean
No deterministic risk flag. Risk fires only on an exact blocklist match, or a reserved-brand name with a mismatched verified payTo. Never from low uptime, a high price, or a model guess.
traction ---
No settlement address is mapped for this service yet, so on-chain volume cannot be measured. Shown as unmeasured, not zero.

RECENT CHECKS
OVER TIME
All charts share the 30d window selected here. Every series is also served as JSON at /api/v1/services/goldrush/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).
Median across 2 endpoints. Use the selector to isolate one.
