Summary

Cetus Protocol is a concentrated liquidity market maker (CLMM) decentralized exchange deployed on the Sui and Aptos blockchains. On May 22, 2025, the protocol suffered one of the largest DeFi exploits in history when an attacker exploited an integer overflow vulnerability in its smart contract math library to drain approximately $223 million from liquidity pools. Roughly $162 million was frozen on-chain through emergency validator action by the Sui network, and following a governance vote the protocol relaunched in June 2025 with partial user compensation.
