Sui
Summary
Sui is a Layer 1 blockchain developed by Mysten Labs, launched in May 2023 and built on the Move programming language. The network suffered one of the largest DeFi exploits of 2025 when Cetus Protocol — its primary DEX — was drained of approximately $223 million in May 2025, triggering a controversial emergency validator vote to freeze and reclaim stolen funds that exposed deep centralization concerns. Separately, ZachXBT investigated a $29 million SUI token theft in late 2024 involving Tornado Cash laundering and subsequently announced in July 2025 that he would no longer take Sui ecosystem cases due to inadequate incident-response infrastructure and lack of support from the ecosystem.
