Star Xu posted on X on 2026‑11‑07, stating that OKX follows a basic technical design rule that a user identifier (UID) must be globally unique across all OKX sites or else cross‑site internal transfers using only the UID are prohibited. He explained that the UID is the account identifier and allowing the same UID on different sites to be used for transfers could lead to mistaken recipient identification and fund loss. Xu emphasized that many major risks stem from small defects accumulating, and he expressed confusion over why such a simple issue became a hot topic in the Chinese crypto community, noting the harassment of a user who suffered losses due to a platform flaw and the defensive stance of other platforms.

“我来简单说一下。 这首先是一个非常基础的技术设计和账户安全问题。 在 OKX 品牌下，我们坚持一个基本原则： 不同站点之间，UID 要么在全局范围内保持唯一，要么就不允许用户仅凭 UID 进行跨站点内部转账。 原因很简单：UID 是账户标识。如果同一个品牌不同站点可能存在相同 UID，却又允许通过 UID 跨站点转账，就可能造成收款账户识别错误和资金误转风险。 千里之堤，溃于蚁穴。所有重大风险都是由很多个小缺陷积累而成。 很难理解，为什么这么简单的一个问题，会演变成简中 X Crypto 社区的一个热点。 更令人不解的是，居然还有那么多账号针对一位由于某平台缺陷导致资产损失的用户进行谩骂、人身攻击，同时替相关平台洗地。 究竟是什么样的企业文化和价值观，在背后推波助澜？”
