Summary

Unizen is a cross-chain DEX aggregator and smart exchange ecosystem operating on Ethereum and multiple other networks, with a native utility token ZCX. On March 8, 2024, the platform suffered a $2.1 million exploit caused by an unsafe external call vulnerability introduced during a smart contract upgrade; the attacker subsequently laundered the stolen funds through Tornado Cash in August 2024. Despite a CEO-funded reimbursement covering approximately 99% of affected users, the incident raised significant questions about upgrade security practices given that two prior audits (Halborn, Verichain 2022) had not caught the flaw.
