CEXQA is a free Chinese-language research tool for checking which centralized exchanges list a coin, comparing published withdrawal fees, and reviewing supported deposit and withdrawal networks. It covers Binance, OKX, Bybit, KuCoin, Gate, Bitget, MEXC and HTX. Users can also browse exchange announcements and explanatory guides. Data comes from official public exchange information and is normally refreshed every six hours, with timestamps and limitations shown on the site. No account or wallet connection is required. Users should verify current fees and availability with the exchange before transferring funds.
