Velodrome Finance is an automated market maker (AMM) and decentralized exchange (DEX) launched on June 2, 2022, on the Optimism Layer 2 network. It is a fork and improvement of Andre Cronje's Solidly Exchange, implementing a ve(3,3) governance and liquidity incentive model. The protocol has experienced three documented security incidents: an insider theft of $350,000 by a team member in August 2022, a DNS/frontend social-engineering attack in November–December 2023 resulting in approximately $250,000 in user losses, and a second DNS hijacking in November 2025 attributed to a NameSilo registrar insider, resulting in estimated losses of $700,000–$1,000,000. Smart contracts have not been directly exploited; all monetary losses have stemmed from front-end and operational security failures.

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.
