Upbit Lists CP and USELESS, Cancels HEMI Debut Following Smart Contract Exploit

Key Facts

In a move highlighting the persistent security challenges within the digital asset sector, Upbit exchange listed Cluster Protocol (CP) and Useless (USELESS) tokens while abruptly canceling plans for HEMI. According to reports, the cancellation followed the discovery of a smart contract exploit that drained 124.5 million unclaimed tokens from a legacy contract, forcing the exchange to abandon support just 18 minutes before the scheduled trading debut.

Technical data indicates the attacker moved 124.5 million HEMI tokens across multiple networks including Ethereum, Arbitrum, and Polygon, converting them into stablecoins and Ether for proceeds of approximately $255,000. Meanwhile, the listings for CP, described as AI infrastructure, and USELESS proceeded as planned against BTC and USDT pairs, per market data regarding the exchange's expanded token offerings.

With real-time price data for these specific instruments unavailable as of September 9, 2026, traders are focused on exchange stability following the exploit. On the macroeconomic front, the market is looking toward the upcoming ISM Services PMI data in the United States as a potential catalyst for broader risk sentiment in alternative asset markets.
