The Sui (SUI) token fell over 5% on Friday, May 23, 2025, following news of a security breach on Cetus Protocol, the largest decentralized exchange (DEX) operating on the Sui and Aptos blockchains. The breach has significantly impacted investor sentiment, raising fresh concerns about the security and stability of the Sui ecosystem.
According to a statement from Cetus Protocol posted on X.com, the platform was exploited by a hacker who managed to steal roughly $223 million in crypto assets. The DEX has since paused $162 million of the stolen funds and is actively investigating the incident in collaboration with the Sui Foundation and other partners.
While Cetus claims to have identified the Ethereum wallet address involved and is negotiating with the attacker, about $61 million remains unaccounted for (source). The attack represents one of the largest security breaches involving the Sui blockchain to date.
The price of Sui dropped to approximately $3.63, down from an intraday high of $3.75, according to data from CoinMarketCap. The token’s trading volume exceeded $1 billion, indicating heightened activity amid market fear. Sui’s total market capitalization currently stands near $12 billion.
Security issues are not new to crypto markets, but they often pose reputational damage that takes time to repair. For Sui, known for its fast transaction speeds and developer-friendly design, this event risks shaking user confidence, particularly among institutional participants who value security and trust.
Despite its technical strengths, this breach could slow momentum for the Sui ecosystem. While developers and users may remain committed to the platform long term, the short-term impact on price and perception is already being felt.
