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.

Attributed pro-quota: this payout address is shared, so volume and buyers are the operator-level figure divided by the services sharing it. A declared convention, not an individually observed measure, and still a conservative undercount.
Top buyer share is a concentration signal, not part of the ranking score.

"description": "Critical-minerals supply-concentration & US import-reliance signal. For a mineral commodity (rare earths, gallium, germanium, cobalt, lithium, graphite, antimony, tungsten, nickel, platinum-group metals, and 70+ more), returns: world mine-production concentration by country (ranked top producers with share, China's share, and an HHI concentration score), US net import reliance and the major foreign sources, reserves concentration by country, and whether it is a USGS-designated critical mineral. Use it to assess supply-chain and geopolitical exposure — China/adversary control of a mineral, US import dependence, and single-country concentration — before a sourcing, policy, or investment decision.

OVER TIME
All charts share the 24h window selected here. Every series is also served as JSON at /api/v1/services/strategicmaterials/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).
Shared payout address (45 other services). These bars are the full shared address (operator-level), so do not sum them across the services that share it. Where a per-service figure is attributed, the assessment block and the ranking, it is the address total divided pro-quota by the 46 services sharing it: a declared convention, not an individually observed measure.
