Cetus

Cetus operates as a decentralized exchange on the Sui blockchain, allowing users to trade digital assets directly from their wallets without intermediaries. The platform provides liquidity pools where participants can deposit token pairs and earn a share of the trading fees generated by swaps. It serves the global cryptocurrency market, primarily targeting traders and liquidity providers who interact with Sui‑based tokens and, through its bridging functionality, assets from other chains such as Ethereum. Access is permissionless, requiring only a compatible wallet and an internet connection.

Cetus distinguishes itself by concentrating exclusively on the Sui ecosystem, which is designed for high throughput and low latency, enabling rapid transaction finality. Its smart‑contract architecture is permissionless, meaning anyone can create a market, add liquidity, or initiate a bridge without needing approval from a central authority. While the protocol is released as open‑source software, the available sources do not disclose a parent company, subsidiary, or formal corporate entity, suggesting a community‑governed development model. The platform’s design emphasizes composability, allowing other Sui‑based projects such as the money market Scallop to integrate with its liquidity pools.

The scale of activity on Cetus became evident during the security incidents of May and January 2025, when the protocol processed movements of hundreds of millions of dollars in a short time frame. In the May 2025 exploit, the team confirmed that approximately $223 million was stolen, with about $162 million subsequently frozen, and the attacker bridged at least $63 million to Ethereum while moving roughly 20 k ETH. The exploiter’s wallet was observed holding nearly $52 million in Sui tokens and other assets, and Sui validators began ignoring transactions from the associated addresses. These events prompted downstream protocols such as Scallop to halt borrowing and led to a temporary pause of the Cetus smart contracts for safety while an investigation continued.
