Internet reports that Cetus Protocol, a Sui native decentralized exchange that suffered a massive $220 million attack in May, said it is moving forward with open source plans after its recent restart. On May 22, an attacker used a pricing mechanism flaw to withdraw tokens from Cetus's main liquidity pool. The agreement successfully froze $162 million in stolen funds shortly after the attack. Cetus 'trading volume had been on the rise before the attack, exceeding $5 billion in April and reaching $5 billion in May, although operations were suspended after May 22. In a June 7 Medium blog post, the Cetus team said the day before the restart that it was moving towards full open source and launched a new white paper bounty program to "encourage collective contributions in technology and security." As part of the reboot, the team said they worked "day and night" to fix the software vulnerabilities that led to the hack, restore pool data to the correct price, and conduct a security audit of all code fixes and contract upgrades.
