Interdax follows a maker-taker model. The fees charged depend on whether the trader is a market maker or market taker:
- Market makers (who provide liquidity and successfully submit limit orders that are rested on the order book) do not incur fees at all, since the maker fee is 0.00%.
- Market takers (who take liquidity from the order book by using market orders or limit orders that remove resting orders) are charged a 0.05% fee of the value of a transaction.
Fees are charged in the settlement currency depending on the instrument: BTC, ETH, USDT, etc.
Trading Fee Example
You can check the fees paid on your trades by clicking on the Profile panel. Then select ‘Transaction History’ and the fee paid for each trade is displayed under the ‘Fee’ column.
Suppose a trader wants to long on 10,000 BTC-PERP contracts and enters a position with a market order. Since 10,000 BTC-PERP contracts have a value of $10,000 if the price of bitcoin is $10,000, the transaction fee will be:
- $5.00 (=0.05%*$10,000)
However, suppose the trader goes long on 10,000 BTC-PERP contracts but enters the position with a limit order that is rested on the order book. No trading fees apply in this case since the maker fee is 0.00%.
For the same position size of 10,000 but for ETH-PERP contracts, the trading fee would be paid out of the ETH balance instead.
Similarly, for stablecoin perpetuals the fees will be deducted from your USDT balance.
For spot trades, the fees for bids are paid in USDT while for asks the fee will come out of the balance for the base currency (e.g., BTC or ETH).
