Upbit Exchange News: ICON Delisted After Security Risks Remain

Upbit Exchange News: Why Is ICON Losing Its Korean Won Market? South Korea's largest crypto exchange just pulled the plug on one of its longest-running won-denominated markets. The latest Upbit Exchange News centers on ICON's native token, which will lose its Korean won trading pair on October 19, closing out a review that began nearly two months earlier.

Every open order still sitting on the books gets cancelled automatically once the pair comes down.

Its native token has traded against the Korean won on this platform for years, making the pair one of the more established Korean-language markets for the project. This wasn't a snap decision. The platform placed the asset on its investment caution list weeks before the delisting notice, a designation it uses specifically to warn traders that a market could get removed if flagged issues don't get resolved. After completing its review, officials determined those security concerns remained unaddressed and moved to end support entirely. The caution designation followed a real network incident: ICON suffered a replay attack in which previously signed withdrawal messages were reused more than a thousand times, releasing a large volume of tokens and knocking the network offline for roughly a day. The official notice ties this decision directly to that unresolved risk rather than to trading volume or general project inactivity. What Happens To Your ICX After October 19 Losing the trading pair isn't the only change coming. Several related services get shut off at the same time: Won-denominated order matching ends completely Airdrops tied to the token will no longer be credited Wallet upgrades stop being supported Migrations are no longer processed Hard fork support for the asset ends Withdrawals stay open a full month longer than trading does, giving holders until November 18 to move their tokens off the exchange before that window closes too. This Isn't Upbit's First Security-Related Delisting Today's Upbit Exchange News fits a pattern rather than standing alone. The platform has used this same caution-then-delisting process on other assets facing unresolved risk flags, most recently ending support for Synthetix (SNX) through a comparable review. That consistency suggests a standard internal playbook is being applied here, not unique treatment aimed at ICON specifically.
