OKX Founder Star Xu Says Sites Use Globally Unique IDs or Block UID-Only Transfers

OKX founder Star Xu said OKX follows a rule requiring globally unique user IDs (UIDs) across its branded sites or blocking internal transfers based only on a UID, a safeguard against misdirected funds.

If separate sites assign the same UID to different accounts, a transfer using only that number could identify the wrong recipient and send funds to the wrong account, Star said. A UID identifies an account.

The statement follows a Binance customer's mistaken transfer to another account. Binance co-founder 何一 said the customer entered a UID on Binance's main platform while trying to send funds to Binance Thailand. The transfer reached another account, and Binance froze 11,398.77 Tether (USDT), she said.

Binance's main platform assigns unique UIDs to its users, while its local platforms in Thailand, Turkey and the United States use separate account systems, 何一 said. She said the customer used a UID rather than a wallet address or QR code and confirmed the transfer without carefully checking the recipient details.
