ICX Upbit Exchange News: Why is ICON losing its Korean won trading market?
South Korea's largest cryptocurrency trading platform has just terminated one of its longest-running won denominated markets. The latest Upbit exchange news focuses on ICON's native token, which will stop trading pairs with the Korean won on October 19, marking the official end of a nearly two-month review process.

According to the exchange's official notice, trading support for this token and the Korean won will end at 3:00 pm Korean Standard Time (KST) on October 19, 2026. Once the transaction pair is removed, all pending orders will be automatically cancelled.

ICON is a Layer-1 blockchain project launched in 2017 established by a Seoul-based foundation to connect individual blockchain networks. For many years, its native tokens have been trading with the Korean won on the platform, making it one of the more mature trading pairs for the project in the Korean market.
这一决定并非一时兴起。在发布退市通知前的数周，平台已将该资产列入“投资警示名单”。这是平台专门用于警告交易者的一种机制，表明如果标记的问题未得到解决，市场可能会被移除。在完成审查后，官员们确定这些安全隐患仍未解决，因此决定完全终止支持。
此次警示标记源于一起真实的网络事故：ICON遭受了重放攻击（replay attack），此前签名的提款消息被重复使用了一千多次，导致大量代币被盗取，并使网络离线约一天。官方通知明确指出，这一决定直接与该未解决的风险有关，而非交易量或项目的一般性不活跃。
10月19日之后ICX会发生什么
失去交易对并不是唯一的变动。几项相关服务也将同时关闭：
- 韩元计价的订单匹配功能完全终止
- 与代币相关的空投将不再计入钱包
- 钱包升级服务停止支持
- 迁移处理不再进行
- 对该资产的硬分叉支持终止
提款窗口将比交易窗口多开放整整一个月，持有者有直到11月18日的时间将代币移出交易所，在此之前该窗口也将关闭。
这并非Upbit首次因安全原因退市
Today's Upbit exchange dynamics follow a pattern rather than isolated events. The platform has used the same "alert first, delist later" process on other assets facing unresolved risk flags, most recently ending support for Synthetix (SNX) through a similar review process. This consistency suggests that standard internal operating manuals are used here rather than special treatment for ICON.
What should ICX holders do now
Anyone who still holds the asset needs to focus on two different deadlines, not just one.
Cryptocurrency trading rights will disappear on October 19, while withdrawal rights will remain open until November 18. Wait until the final stage of the second window before acting. If you encounter network congestion or processing delays, there will be little room for fault tolerance. This round of Upbit exchange dynamics places special emphasis on the need to act as soon as possible, and don't assume that a one-month overlap period can ensure smooth processing until the last minute.
This round of Upbit exchange dynamics reminds people that the investment warning label is not just a warning sign, it is often the first visible sign for a platform to completely abandon an asset.
