anchored·5pyjC3…jc73Summary
0VIX was a DeFi lending protocol built on Polygon PoS and Polygon zkEVM, forked from the Compound v2 codebase, that launched as one of Polygon zkEVM's inaugural partners. On April 28, 2023, an attacker exploited a price oracle vulnerability in the protocol's vGHST market using a flash loan, draining approximately $2 million in user funds from a total TVL of $6.4 million. Stolen funds were bridged to Ethereum via Stargate Finance and deposited into Tornado Cash; the attacker did not respond to a $125,000 bounty offer. The protocol subsequently rebranded as Keom in August 2023.
