Cetus Protocol has resumed operations after a vulnerability attack and is planning to open source

According to a report by Jinse Finance, Cetus Protocol, a Sui-native decentralized exchange that suffered a massive $220 million attack in May, stated that it is advancing its open-source plan following a recent relaunch. On May 22, an attacker exploited a pricing mechanism vulnerability to siphon tokens from Cetus's main liquidity pool. The protocol successfully froze $162 million of the stolen funds shortly after the attack. Prior to the attack, Cetus's trading volume had been on an upward trend, exceeding $5 billion in April and reaching $5 billion in May, despite halting operations after May 22. In a Medium blog post on June 7, the Cetus team stated, a day before the relaunch, that they are moving towards full open-source development and launching a new white paper bounty program to "encourage collective contributions in technology and security." As part of the relaunch, the team mentioned they have been "working day and night" to fix the software vulnerabilities that led to the hack, restore pool data to the correct prices, and conduct security audits on all code fixes and contract upgrades.
