Cetus DEX Relaunches with Open-Source Shift After Exploit

• Cetus DEX resumes with 85-99% pool recovery. 
• $30M loan, $7M reserves restore liquidity. 
• Open-source shift starts in Q3 2025.

A decentralized exchange on Sui blockchain, Cetus Protocol, relaunched on June 8, 2025, a month after a $220 million exploit in May. Token swaps, liquidity provision and staking are now all supported by the platform. The liquidity pools that were affected have between eighty-five and ninety-nine percent of their original capacity. This is due to the fact that the Sui Foundation provided a loan of thirty million dollars, and seven million dollars came from the reserves used by Cetus.

The flaw is in the shared math library contract, which allowed unauthorized withdrawals, according to the exploit. The vulnerability was patched by Cetus, and extremely rigorous security audits were done, and real-time monitoring was put in place to avoid further breaches. The authorities in several jurisdictions are cooperating, and legal action against the attacker continues.

As a means of compensating users for their losses, a compensation contract provides a CETUS token and distributes fifteen percent of the entire quantity of CETUS tokens over the course of one year. An initial 5% is available immediately through the platform’s updated interface. Via Cetus’s official portal, users are able to verify claims and monitor distributions.

The total amount locked has recovered from the low that it reached following the exploit and is currently at an astounding $124 million as a consequence of the relaunch. This is a significant improvement from the previous low. Cetus is currently rated among the top 10 decentralized exchanges (DEXs) on Sui. This is a result of the increased trading volume that exists on the platform.

Open-Source Model to Bolster Security

In order to increase transparency and security, Cetus is moving to a fully open-source framework. Starting Q3 2025, the shift opens core contracts for community review and contributions. It will have a white bounty program where developers will be rewarded for their findings and for proposing fixes.

Cetus shared its path forward with its respective channels, ‘Transparency and community collaboration are our path forward.’

The user interface of the protocol has been upgraded with real-time analytics and streamlined trading tools. Multi-factor authentication is used for high-value transactions, and automated alerts are sent for suspicious activity. Uniswap, for instance, witnessed a twenty percent increase in the number of developer contributions when it became open source, as reported by Uniswap Governance. When it comes to this company, this is a move that makes perfect sense.

Cetus aims to rebuild trust through these measures. According to Cetus Medium, the recovery strategy is described in depth, with a particular emphasis on user security and system resilience. This redesign establishes Cetus DEX as a community-driven and secure trading platform, which is a new stage for the platform.
