Sources & method
Skontro's founding EUR series — the longest continuous record, running on as a continuing service beside the dollar edition. Each exchange is priced separately on every measured asset, then averaged into one number. 12,380 measurements in 1,448 asset-hour rounds (1,448 rankable), observed 2026-06-23 → 2026-06-30 · 25.1% of scheduled asset-hour rounds (partial calendar-month coverage).
Basket v1: the founding 8-asset series. * = estimated, not measured: a list-price exchange with no public order book; excluded from the cheapest/dearest rounds. Not assessed = a thin order book or an exchange no longer compared; shown for the record, never ranked. Ranking is by net amount received; affiliate relationships never move a number. How “hidden spread” is measured: /true-cost/methodology. Corrections → hello@skontro.com, applied and dated visibly.
