TT Key insight: Upbit removes the ICX/KRW trading pair due to security risks.
Crypto news reports pointed out that Upbit will cancel the ICX/KRW trading pair due to security issues on October 19, 2026. Upbit will cancel all outstanding ICX/KRW orders and support withdrawals until November 18.
JPYC rose 197.5% to 35.7 won after Upbit went online, and then fell back to about 8 won.
South Korea Crypto News covers Upbit's decision to remove ICX/KRW transactions due to unresolved security issues. The exchange will close trading on October 19, 2026 at 3:00 pm (Korean Standard Time). At that time, outstanding orders will be cancelled and ICX withdrawal services will continue to be provided until November 18.
Upbit stated that ICON may be at risk of security incidents that have not yet been resolved or lack adequate corrective measures. These concerns persisted after the launch of ICX as an investment warning asset.
Crypto News Focus on ICX Security Issues
According to Upbit, it supports terminating transaction support for the ICX/KRW transaction pair in view of the reasons that have not been resolved after early warnings were specified. Its notice clearly states that safety issues are the basis for removing the market.

For users holding ICX, transaction access will end before withdrawal support is turned off. When the October 19 deadline comes, orders that are still pending will be automatically cancelled. However, holders can continue to withdraw their tokens through November 18, after which the pair will cease trading.
Upbit 新闻：早期代币下架引用其他缺陷
加密新闻报道紧随此前关于 JASMY、Storj 和 ThunderCore 交易对的公告。Upbit 指出了涉及 JASMY 和 STORJ 的披露、业务基本面、可行性和进展证明等问题。
它表示这些问题导致其决定终止支持，并引用了对用户造成伤害的风险。
对于 ThunderCore，交易所提到了关于总发行量、流通计划以及业务计划变更的担忧。它还引用了透明度和程序完整性方面的不足。这些担忧伴随着 TT 市场与 JASMY 和 STORJ 交易对的一同下架。
受影响的市场包括 STORJ/KRW、STORJ/BTC、JASMY/BTC、JASMY/USDT、TT/KRW 和 TT/BTC。Upbit 表示，当交易支持结束时，它将取消所有未成交订单。此前的通知允许受影响的资产提币至 10 月 14 日。
除了加密新闻外，交易所还概述了针对等待下架代币的其他服务限制。它表示不会为这些资产提供支持空投、钱包升级或硬分叉。这些服务变更是早期下架公告的一部分。
加密新闻：JPYC 上市记录强劲上涨和下跌
In addition, in addition to South Korean crypto news, reports on the listing of Upbit JPYC described price fluctuations shortly after trading began. Trading in the yen stablecoin began at 6:00 pm and reached 35.7 won in 40 minutes. This marked a 197.5% increase from its opening price and then back into the 8 won range.
Each JPYC is convertible for 1 yen, and the report puts its value at approximately 8.8 won. According to reports, about 120 billion won in purchase orders poured in immediately after the listing. At the time, Upbit reportedly accounted for about 90% of JPYC's trading volume.
Deposits and withdrawals are initially unavailable, preventing holders from bringing external tokens into Upbit for sale. The exchange opens both services at 6:50 p.m., approximately 50 minutes after trading begins. Previously, transactions relied on existing tokens and funds within the platform.
The report also quoted a post on X about transactions by Japanese JPYC holders. Those posts claimed that holders exchanged JPYC for Circle's USDC through Uniswap and reported that their funds doubled. Uniswap allows users to exchange tokens directly through connected wallets.
