ZKX Protocol, an Ethereum Layer-2 Starknet-based trading platform, has shut down due to economic challenges and low user engagement. The decision, announced by founder Eduard Jubany Tur on July 31, has led to a significant drop in the value of the ZKX token, which plummeted by 52% within 24 hours. The sudden closure has left investors and market makers blindsided, with many criticizing the lack of transparency and communication from the ZKX team. Despite substantial VC backing from StarkWare, Huobi, and others, the platform could not maintain economic viability. Investors have been advised to withdraw their assets by the end of August. The shutdown occurred on July 30, just a month and a half after an airdrop, raising questions about the millions in funding the platform had received.
