Last week, the decentralized protocol Cetus, which provides core liquidity on the Sui blockchain, suffered a major attack. The hacker withdrew assets totaling $223 million, causing a price collapse and halting trading. Now the project team has announced securing a loan from the Sui Foundation and promises to fully compensate users for their losses.

The Loan Will Ensure Full Reimbursement

According to Cetus representatives, the loan from the Sui Foundation will allow for full coverage of the stolen assets, provided the community approves the use of frozen funds through a vote. These measures aim to reimburse users for assets that were taken off-network and not frozen on-chain.

“With our treasury and tokens, as well as the critical loan from the Sui Foundation, we are able to provide 100% compensation to affected users,” the Cetus statement reads.

The Outcome of the Attack Depends on Voting

The recovery plan depends on the results of a community vote, which must authorize the use of the frozen tokens. If approved, the funds will be directed toward completing user reimbursements.

“Sui Foundation took emergency measures to protect the ecosystem,” the foundation stated, adding that with community support, full reimbursement is achievable.

At the time of writing, the Sui community proposal titled “Should the stolen assets of the Cetus protocol be returned via a special transaction” had received nearly 54% of votes in favor, and the proposal was passed.

How the Hack Happened

During the attack, the perpetrator used counterfeit tokens to bypass the liquidity pool’s pricing and reserve mechanisms. This allowed them to withdraw real assets such as SUI and USDC without providing equivalent collateral.

According to the team, $162 million was frozen on-chain. The remaining funds were bridged to other networks. At the time of publication, the attacker’s wallet remained active and held 12.9 million SUI, with some assets possibly exchanged or lost in the obfuscation process.

Immediately after the attack, the Cetus team disabled smart contracts and launched an investigation. The CETUS token dropped nearly 40%, but has already regained about 28% of its lost value. In addition, decentralized application activity across the network fell sharply following the attack, as market participants began withdrawing liquidity due to fears of further risks.
