Cetus Offers $5M Bounty Following Sui DEX Hack

Initiated by Cetus Protocol, the $5 million bounty is an attempt to identify the hacker following the recent breach of their Sui-based DEX. The protocol suffered a substantial loss of $223 million in May 2025. Following the breach, Cetus initially offered a $6 million reward to the hacker for the return of stolen assets. With no response, Cetus, along with cybersecurity firm Inca Digital, opted to offer a public bounty instead.

The funds were frozen by Sui validators, preventing further transfers of the stolen $162 million. This swift action, however, sparked controversy over the network’s decentralization.

Sui validators are blocking malicious transactions to prevent further movement of the stolen assets.

Financially, the incident resulted in a dip in token values such as SUI and ETH and also impacted the overall liquidity within the Sui ecosystem.

The use of validator powers to freeze funds has raised concerns over the extent of centralized control in DeFi systems. The community continues to debate the implications for network autonomy. Cetus’s actions parallel previous high-profile exploits and interventions, emphasizing the tension between decentralization and emergency response protocols in crypto networks.
