Starknet-based ZKX protocol, a social derivatives trading platform, has closed operations. Founder Eduard Jubany Tur cited minimal user engagement, decreased trading volumes, and insufficient revenue as reasons for the shutdown. The protocol delisted all markets, closed positions, and returned funds to users' trading accounts. This closure comes shortly after ZKX raised $7.6 million in funding. The protocol's native ZKX token has seen a significant price drop, reflecting broader DeFi sector challenges.
