South Korean cryptocurrency exchange Upbit will delist the ICX/KRW trading pair on October 19, 2026, citing unresolved security incident risks associated with ICON (ICX). Details of the announcement were shared by Wu Blockchain on X, and the report was carried by Hokanews.

Trading support for the ICX/KRW market will end at 3:00 p.m. Korea Standard Time on October 19. At that point, all outstanding orders for the pair will be canceled as the exchange removes the market from its platform.

Upbit Cites Unresolved Security Incident Risks

According to Wu Blockchain, Upbit stated that ICON (ICX) may face security incident risks that remain unresolved or unremedied. The exchange said these issues have not been resolved since ICX was designated as an investment caution asset.

That designation indicates that concerns previously identified by the exchange remain relevant to its decision on whether to continue supporting the asset's trading pair. Upbit's announcement specifically tied the termination of trading support to the unresolved status of those concerns. For traders, an investment caution label functions as the exchange's standing notice that an asset carries outstanding issues, and the progression from a caution designation to a full delisting marks an escalation in how the exchange is treating those unresolved concerns.

The delisting applies to the ICX/KRW market, which allows users to trade ICX directly against the South Korean won. With that market removed, Upbit users lose the direct route for buying or selling ICX with won on the platform. The announcement does not state that the ICON blockchain itself will cease operating, nor does it address ICX trading on other platforms.

Withdrawals to Continue After Trading Ends

Although trading support will end on October 19, Upbit will continue to allow withdrawals of ICX until November 18, according to the information shared by Wu Blockchain. The additional window gives users roughly one month after trading stops to move their holdings off the exchange. The announcement does not describe arrangements for ICX that remains on the platform after the withdrawal deadline.

The end of trading and the later withdrawal deadline therefore represent separate stages in Upbit's handling of the asset. Users with open ICX/KRW orders will also need to account for the cancellation of outstanding orders when trading support ends at 3:00 p.m. KST on October 19.

ICON and the ICX Token

ICON is a Layer 1 blockchain that was launched in 2017. Its native token, ICX, has primarily been used for network transactions, staking, and governance. An asset's trading availability on individual exchanges can differ from the operation of the underlying blockchain; in this case, Upbit's announcement concerns support for the ICX/KRW trading pair and the withdrawal period that follows, not the network's own transaction, staking, and governance functions.

The immediate timeline outlined by the exchange is the October 19 termination of trading support, followed by continued ICX withdrawals through November 18, 2026.
