Cetus Offers $5M Bounty Following $223M Sui Hack

Cetus Protocol has offered a $5 million bounty on May 23, 2025, for information leading to the hacker responsible for a $223 million security breach on the Sui network.

The incident highlights issues of security and centralization within decentralized networks, as Sui validators quickly froze $162 million of assets. This move led to a significant market impact, notably affecting Sui token values.

Security Breach Details

Cetus Protocol, a major decentralized exchange on the Sui network, experienced a security breach on May 22, 2025, losing approximately $223 million. The team has announced a $5 million bounty with support from the Sui Foundation, aiming to identify and apprehend the hacker.

Cetus had earlier attempted a white hat settlement with the hacker for $6 million.

The financial implications have been severe: Sui validators managed to freeze $162 million, but the venture continues to affect Sui tokens’ market value. The exchange’s urgency to manage the breach reflects broader concerns on decentralized governance.

Centralization Concerns

Centralization concerns emerged when Sui validators coordinated to freeze compromised assets. The incident has drawn criticism about the network’s governance, as stakeholders debate the appropriate level of centralized control within such decentralized ecosystems.
