Methodology: how the board is built

What we measure

Volume. 24-hour, 7-day and 30-day turnover as reported by each venue’s public API or published statistics page. We never blend spot with derivatives, and we print the sampling date on every row.

Fees. The published entry tier for maker and taker, plus the withdrawal fee on the network a normal user would pick. VIP ladders are excluded because almost nobody qualifies and they flatter the headline number.

Markets. The count of tradable pairs listed by the venue at the time of the check.

What we do not do

• We do not accept payment for a position in the ranking.
• We do not adjust reported volume for suspected wash trading; we label it as venue-reported instead.
• We do not score a venue on brand recognition.

Corrections

If a figure is wrong, send the row and the source. Corrections are applied in place and the verification date moves forward, so you can see the change rather than take our word for it.
