MCDEX is a decentralized exchange and layer 2 platform that allows users to trade perpetual contracts.

Whitehat Lucash-dev, who is a member of Immunefi’s Whitehat Scholarship, submitted a critical vulnerability in MCDEX’s broker contract that would have allowed a malicious user to drain that contract of ETH. It does not appear as though the vulnerability was ever exploited, and at the time of the report, funds at risk were insubstantial. MCDEX is paying Lucash-dev a bounty of $50,000 and has patched the bug.
