OKX TR to migrate USDⓢ spot trading pairs

Dear OKX TR users,

To further consolidate spot market liquidity and provide a more consistent trading experience, OKX TR will gradually migrate USDⓢ spot trading pairs. After the migration, trading will be supported by the corresponding USDC spot trading pairs, which will be displayed as Crypto-USDⓢ.

USDC pair availability and parallel trading period

Starting from 8:00 UTC on September 23, 2026, OKX TR will make the relevant USDC spot trading pairs available. Selected USDⓢ and USDC trading pairs will then be available in parallel for a period of time, allowing you to move your trading activity to the corresponding USDC pairs in advance. The relevant USDC pairs will support trade with USDC, USDG, and RLUSD.

Delisting of USDⓢ trading pairs

At 8:00 UTC on September 30, 2026, OKX TR will delist the relevant USDⓢ spot trading pairs, except USDT-USDⓢ. At that time:

• The affected USDⓢ spot trading pairs will no longer be available for trading;

• All open orders for the affected pairs will be automatically canceled;

• Trading bots using the affected USDⓢ pairs will gradually close between 07:00 and 08:00 UTC on the respective delisting dates. If you are concerned about potential fees or slippage from automatic closures, we recommend stopping them manually;

• Strategy orders, trading bots, and API programs using the affected USDⓢ pairs will no longer be able to place orders;

• Please switch to the corresponding USDC pairs and create new orders or strategies in advance.
  

Trading pair display update

After the USDⓢ pairs are delisted, the relevant USDC pairs will be displayed as Crypto-USDⓢ on the OKX TR web and app interfaces. For example, BTC-USDC will be displayed as BTC-USDⓢ. This is a display-name change only. Trading will continue to be supported by the corresponding USDC pairs.

API Impact

Requests that currently use a Crypto-USD instrument ID must use the corresponding Crypto-USDC instrument ID after the change goes live. If you currently trade a Crypto-USD instrument without specifying tradeQuoteCcy and want to continue trading with USD after migrating to the corresponding Crypto-USDC instrument, you must explicitly set tradeQuoteCcy to USD. More details can refer to API Changelog.

Risk warning: Digital assets are highly volatile and involve significant investment risks. Please fully understand the relevant rules and make investment decisions cautiously.
