Cetus DEX Recovers After $220M Hack
Cetus DEX Recovers After $220 Million Hack
Cetus Protocol, a Sui-native decentralized exchange (DEX), has relaunched after a significant $220 million exploit in May. The attack, which exploited a pricing mechanism flaw, drained tokens from Cetus's major liquidity pools on May 22. While the protocol managed to freeze $162 million of the stolen funds, the incident highlighted vulnerabilities in the DeFi space.
Before the attack, Cetus saw impressive trading volume, exceeding $5 billion in both April and May. Following the incident, the Cetus team worked diligently to restore the platform.
Relaunch and Recovery Efforts
The relaunch, announced on June 8, followed a comprehensive recovery plan. This included:
- Patching the software vulnerability that caused the exploit.
- Restoring pool data to correct pricing.
- Conducting thorough security audits on all code fixes and contract upgrades.
- Replenishing affected liquidity pools using a combination of $7 million in cash reserves, a $30 million USDC loan from the Sui Foundation, and recovered assets.
While not all pools were fully restored, the recovery rate stands between 85% and 99% depending on the pool's initial losses.
Compensation and Future Plans
Cetus has allocated 15% of its native token supply, CETUS, for user compensation. 5% is available immediately, with the remaining 10% linearly unlocked monthly over the next year. Despite these efforts, the CETUS token price has experienced a recent drop.
The team is committed to enhancing security, planning upgrades to its protocol monitoring system and further security audits. They are also pursuing legal action in multiple jurisdictions to recover the remaining stolen funds.
