- The Cetus hack resulted in a $223 million loss.
- $160 million stolen funds now in multi-sig wallet.
- Community and validator coordination halted further damage.

The Cetus protocol has moved $160 million in stolen funds to a multi-sig wallet following a major exploit. The attack targeted the largest decentralized exchange on the Sui network on May 22, 2025.
The incident highlights the vulnerability in Cetus’ system and raises questions about decentralized security. Rapid coordination helped contain the damage, providing a crucial test for Sui’s security protocols.
Within the Sui network, Cetus suffered a $223 million hack due to a vulnerability. Attackers exploited a flaw in the application logic, swiftly draining liquidity. Efforts by Cetus developers and the Sui Foundation played a crucial role in freezing funds.
Validators and community members collaborated to update network configurations, blocking the attacker’s wallet. The funds were frozen and moved to a multi-sig wallet under the control of Cetus and the Sui Foundation, safeguarding assets. According to Adeniyi Abiodun, Co-founder, Mysten Labs, Sui Foundation, “It’s not a bug in Sui consensus, it’s not a bug in Move,” specifying fault was with Cetus’ application code, not the core blockchain.
The attack resulted in depleted liquidity and affected major tokens like SUI and USDC. The Sui network’s swift response prevented further losses. The liquidity drain was halted, maintaining market stability for now.
Financially, the hack deeply impacted the Sui ecosystem, challenging trust. It highlights key security concerns inherent in decentralized networks. The incident led to debates on governance and potential centralization in emergency interventions.
Future implications hinge on addressing security vulnerabilities and improving protocol governance. Past incidents show the ongoing risks in DeFi. The Sui network’s response will likely influence future blockchain security strategies.
