OKX to Migrate USD Spot Trading Pairs

OKX plans to merge USD and USDC spot order books into a unified order book to improve liquidity, narrow spreads, and optimize execution quality. Users must migrate open orders and trading bots for USD trading pairs to corresponding USDC pairs between September 23 and 30, 2026. After the migration window closes from 03:00 to 04:00 ET on September 30, the USD order book will be officially deactivated.
