Upbit 发布公告称，已将 FLOW 列为交易警告品种（Investment Warning），该决定由韩国数字资产交易所联合协商体 DAXA 成员共同作出。交易警告品种指定期限为 2025 年 12 月 29 日 14:00（KST）至 2026 年 1 月 14 日 23:59（KST）。Upbit 表示，根据数字资产交易支持相关指引，在综合考虑 FLOW 发生黑客攻击等安全事件、可能对用户造成损失的风险后，基于投资者保护原则作出上述决定。指定期间内，Upbit 将对 FLOW 是否延长注意品种状态、解除指定或最终终止交易支持进行进一步审查，若相关风险未能充分消除，可能作出终止交易支持的决定。公告同时指出，FLOW 的充值与提现服务此前已于 2025 年 12 月 27 日 20:58（KST）暂停。后续若恢复服务，将仅先行恢复提现功能，充值功能是否重启将依据交易注意品种后续审查流程另行公告。Upbit 提醒用户，交易注意品种指定后产生的所有充值将不予入账并进入退回流程。
