OKX to introduce spot fee payment option in quote currency

To further enhance the trading experience, OKX is pleased to announce the launch of a new Fee Payment Option for spot buy orders. This update provides users with the flexibility to choose between the existing default fee deduction method—where fees are deducted from the currency received (i.e., the base currency)—and a new option to pay fees in the currency spent (i.e., the quote currency), thereby ensuring that the full purchased amount is delivered without any reduction.

• For OpenAPI users: please use POST /api/v5/account/set-fee-type

• For web and app users: please refer to the trading account settings page.

  • Web:

    

  • App:

    

Please note that the fee deduction logic for spot sell orders will remain unchanged, with fees continuing to be deducted from the received quote currency.

Details:

• Launch Date: Sep.23 2025

• Fee Charging Methods:

  • Pay in Currency Received: Fees are deducted from the base currency received, thereby reducing the delivered amount.

  • Pay in Currency Spent: Fees are charged in the quote currency in addition to the order amount, ensuring the full base currency amount is delivered.

• Maker Rebates:

  • Makers will receive rebates in the same currency that takers use to pay their fees. For instance, if a taker places a buy order and opts to pay fees in the quote currency, the corresponding maker rebate will also be issued in the quote currency.

• Notes:

  • This trading setting is applied at the sub-account level.

  • Switching payment method is not allowed if there are pending spot orders.

Example (Buy 1 BTC with 100 USDT, fee rate 1%):

• Option A: Pay in Received Currency (BTC)

Spend 100 USDT; fee = 1 BTC × 1% = 0.01 BTC; net received amount = 0.99 BTC.

• Option B: Pay in Quote Currency (USDT)

Spend 101 USDT; fee = 100 USDT x 1% = 1 USDT; receive full 1 BTC.

Thank you for your continuous support.
