Cetus Protocol has resumed operations after suffering a vulnerability attack and is planning to Open Source.

Golden Finance reports that Cetus Protocol, a Sui native DEX that suffered a large-scale attack of $220 million in May, has stated that it is advancing its open source plan after recently restarting. On May 22, an attacker exploited a pricing mechanism vulnerability to withdraw tokens from Cetus’s main liquidity pool. The protocol successfully froze $162 million of the stolen funds shortly after the attack occurred. Before the attack occurred, Cetus’s trading volume had been on the rise, exceeding $5 billion in April and reaching $5 billion in May, despite pausing operations after May 22. In a Medium blog post on June 7, the Cetus team stated that they were moving towards full open source development and launched a new white paper bounty program to “encourage collective contributions in technology and security.” As part of the restart, the team stated that they “worked day and night” to fix the software vulnerability that led to the hack, restored the pool data to the correct price, and conducted security audits on all code fixes and contract upgrades.
