Panic Engulfs Cetus Protocol as Suspected Vulnerability Triggers Massive Liquidity Drain

Cetus, which positions itself as a leading DeFi infrastructure layer for the Sui network, became the center of attention as its smart contracts were abruptly paused due to a critical issue.

Panic swept through decentralized markets on Thursday after a suspected vulnerability in Cetus Protocol triggered a massive liquidity drain across several Sui-based tokens.

What began as a sudden sell-off rapidly escalated into a full-blown DeFi crisis, with certain token prices collapsing by more than 90% in minutes.

Cetus, which positions itself as a leading DeFi infrastructure layer for the Sui network, came under the spotlight as its smart contracts were abruptly paused due to a critical issue. The protocol acknowledged the incident via X (formerly Twitter), promising to share more details soon.

While some tokens like LOFI and HIPPO saw declines of over 50%, others fared far worse, nearly erasing all gains. On-chain data platforms displayed that prices on centralized exchanges held up for a longer period, but signs of broader contagion have since emerged, pulling down the overall Sui token market.

The CETUS token itself wasn't spared—losing about half its value on decentralized exchanges and falling 30% overall in less than an hour.

Blockchain investigators at Lookonchain revealed that over $260 million was drained from the protocol. A significant portion of the stolen funds was converted into USDC, bridged to Ethereum, and then exchanged for ETH. PeckShield, a blockchain security firm, confirmed that over $200 million had been compromised, aligning with the $60 million cross-chain transfer figure.

While initial community reactions speculated a full-scale hack, some developers suggest the root cause might be an oracle manipulation bug—an exploitation of flawed price feeds rather than direct smart contract vulnerabilities.

Despite the technical specifics, the outcome remains clear: tens of millions have been drained, trust in the protocol has been shattered, and Sui's DeFi sector is in turmoil.

The incident serves as a stark reminder of the nascent stage of the blockchain ecosystem and the potential for unforeseen vulnerabilities to have devastating consequences, especially within the interconnected and rapidly evolving DeFi sector.output: A suspected vulnerability in Cetus Protocol has triggered a massive liquidity drain across several Sui-based tokens, setting off a panic in decentralized markets on Thursday.

Cetus has encountered a critical issue, and we are actively investigating. Smart contract operations have been paused as a precautionary measure. We will provide a full statement and further updates shortly. Thank you for your patience and understanding.

Some tokens, such as LOFI and HIPPO, saw declines of over 50%, while others, like Bankless's BNX token, plummeged nearly entirely. On-chain data platforms showed that prices on centralized exchanges held up for a longer period. However, signs of broader contagion have since emerged, pulling down the overall Sui token market.

The CETUS token itself lost around half its value on DEX platforms and fell by 30% overall in less than an hour.

Investigators at Lookonchain reported that more than $260 million was siphoned from the protocol, with a large portion of the stolen funds being converted into USDC, bridged to Ethereum, and then swapped for ETH.
