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.
Currently sharing this payout address with AfriRef - Pan-African government reference data.
Top buyer share is a concentration signal, not part of the ranking score.

] OVER TIME
All charts share the 30d window selected here. Every series is also served as JSON at /api/v1/services/asiaref/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). The on-chain series roll up hourly, so the latest day can be up to about an hour behind; distinct buyers are counted per payout address, so a service that settles to more than one address is an upper bound.

VOLUME (on-chain settlement, USD)
Shared payout address (1 other service). 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 2 services sharing it: a declared convention, not an individually observed measure.
DISTINCT BUYERS
Shared payout address (1 other service). These bars are the full shared address (operator-level), so do not sum them across the services that share it. Where a per-service buyer count is attributed, the assessment block and the ranking, it is divided pro-quota by the 2 services sharing the address and can be fractional: a declared convention, not an individually observed measure.
