Cetus Secures Sui Foundation Loan to Fully Reimburse Users After $223M Exploit
Cetus Protocol, the largest decentralized exchange (DEX) on the Sui blockchain, suffered a major exploit last week, resulting in the loss of $223 million in crypto assets. The attacker manipulated spoof tokens—such as BULLA—to exploit vulnerabilities in the protocol’s price curves and reserve logic, allowing them to drain SUI, USDC, and other legitimate assets from liquidity pools.
Over $162 million in stolen tokens were frozen on-chain, while the remaining funds were bridged out via multiple pathways. The attacker’s wallet remains active, holding at least 12.9 million SUI, with more likely laundered across networks.
Sui Foundation Provides Emergency Loan
In a significant move to stabilize the situation, Cetus has secured a critical loan from the Sui Foundation. This funding, combined with Cetus’s own cash and token treasuries, allows the protocol to fully cover all off-chain stolen assets, provided that the community votes to release the frozen funds.
“Using our cash and token treasuries, we are now in a position to fully cover the stolen assets currently off-chain if the locked funds are recovered through the upcoming community vote,” Cetus stated on X.
“This includes a critical loan from the Sui Foundation, making a 100% recovery for all affected users possible.”
Role of the Community Governance Vote
The on-chain community vote will decide whether to authorize the use of frozen assets to complete the reimbursement. Cetus is urging the Sui community to support this vote:
“We humbly ask for the Sui community’s full support to recover the funds via the upcoming vote. We recognize that this is an extraordinary ask forced by our actions… but we think it is the right decision—especially for those affected.”
Regardless of the vote’s outcome, Cetus said it will initiate reimbursement efforts immediately, with a full recovery plan to be detailed soon.
Impact on Sui Ecosystem and Cetus Response
The exploit caused immediate disruption to Sui’s DeFi ecosystem. Cetus paused smart contracts and launched an internal investigation. The price of its governance token CETUS dropped by nearly 40%, and trading activity across Sui slowed as concerns over protocol security intensified.
In a public apology, Cetus emphasized its commitment to users:
“We deeply regret the impact caused by the recent incident and sincerely apologize to our users and the broader ecosystem for the exposure. Your trust is our top priority, and we are fully committed to making things right.”
Sui Foundation’s Statement and Commitment
The Sui Foundation called the loan an extraordinary measure to protect its ecosystem and emphasized the importance of community unity in an X post:
“These funds apply only to cover the bridged assets, and are separate from the frozen funds subject to the onchain community vote. Taken together with the onchain community vote proposal, a full recovery is possible. Sui Foundation stands strong in its efforts to support its members.”
The secured loan from the Sui Foundation signals a crucial turning point for Cetus and the broader Sui DeFi ecosystem. With a combination of internal resources and community support through governance, the project aims to achieve full restitution for affected users and restore confidence in its protocol.
