Figures from the 28 October 2026 build snapshot. Open the live view for the current rankings.
Volume is a claim about a past that left no artifact. An order book is a claim about the present the exchange has to have standing there when you look. Tranco web rank is the one number nobody can type: it counts resolvers in the wild, not anything the venue reports. That is why the ranking uses web rank as the anchor and treats a deep book as a permission to keep a position, not a reason to promote one.
No curated markets are recorded for One on this build. The exchange's own site is the primary place to browse its pair list; the ranking gathers markets by ASSET, so this section fills in as coins One trades appear in the top-N snapshot.
