OKX said it will list DAPPOS token DOS against USDT on Aug. 13, 2026, opening deposits at 03:00 UTC, running a pre-open session from 09:00 to 10:00 UTC, starting spot trading at 10:00 UTC and enabling withdrawals at 12:00 UTC. The exchange said index-based price limits will apply during the pre-open session and continuous trading, and described DAPPOS as a Web3 AI operating system that combines research, analysis, content creation, strategy planning and on-chain execution. The move adds OKX to earlier DOS spot listings by Huobi HTX and MEXC, with MEXC also describing DOS as the project's utility and governance token, launching DOS/USDT and DOS/USDC pairs on Aug. 10, and running a $70,000 promotional campaign. Huobi HTX had scheduled DOS deposits, DOS/USDT trading and withdrawals for Aug. 11-12, while MEXC cited DAPPOS claims of more than $20 million raised and over $6.8 million in cumulative xBubble revenue.
