Decentralized finance (DeFi) trading platform Unizen lost around $2.1 million after what crypto security firms called an exploit of an "external call vulnerability" in the platform.
Blockchain security and data analytics firm PeckShield reported about the anomaly on X (formerly Twitter) Saturday. "Hi @unizen_io you may want to [take] a look. It looks like an approve issue with >2m loss already," the company said. It also advised the platform to revoke the approved transactions immediately.
