Crypto Exchange Fees

Base-tier maker/taker trading fees for major crypto exchanges (CEX, DEX and perp DEX), each figure read from the exchange's own fee page and dated. No estimates: a value an official page does not state is left empty.

• Machine-readable: data/exchanges.json · data/exchanges.csv

• Fees are percent of notional at the lowest (regular user) tier, before token discounts (e.g. BNB) and before any VIP tier.

• Every row links to the official source it was read from.

Data as of 2026-11-07.

Why this exists

Fee schedules change quietly. Many comparison pages still quote numbers that the exchanges have since replaced (for example, Kraken Pro moved to cross-platform tiers on 2026-07-09 and its tier-1 spot rate is now 0.40% / 0.80%). This dataset records what each official page says, when it was read, and where.

Fields

Method and limits

Figures are read from each exchange's public fee page or official help article and re-checked periodically. Fees can differ by region, account type, trading pair and promotion; always confirm on the exchange's own page before trading. This is not financial advice. Corrections are welcome as issues or pull requests with an official source link.
