South Korean exchange Upbit announced that it will terminate ICX/KRW trading support on October 19, 2026 at 14:00 (UTC+8), and withdrawal services will be open until November 18. The ICON network was subjected to a replay attack on August 27th, with two signed withdrawal messages being reused 1492 times, releasing 119.9 million ICX and 531600 BNUSD, resulting in a network outage of approximately 25 hours. Upbit has determined that the ICX investment warning has not been lifted, and has decided to terminate trading support. It will no longer support ICX's airdrops, wallet upgrades, migrations, and hard forks.
