Upbit will terminate trading support for ICON (ICX) against the Korean won at 3 p.m. KST on Oct. 19, 2026, or 6 a.m. UTC. Unfilled orders will be canceled, while withdrawals will remain available until Nov. 18. The decision follows an Aug. 28 investment warning that remained unresolved after further review. ICON suffered a replay attack on Aug. 27 in which two signed withdrawal messages were reused 1,492 times, releasing 119.9 million ICX and 531,600 bnUSD and stopping the network for about 25 hours. Upbit will also discontinue support for ICX airdrops, wallet upgrades, migrations and hard forks after the announcement.
