How scoring works →Summary
Gamma Strategies is a DeFi active liquidity management (ALM) protocol built on Uniswap v3 and other concentrated-liquidity DEXs, formerly known as Visor Finance. The protocol suffered a significant flash loan exploit on January 4, 2024, resulting in losses of approximately $6.18 million across four vaults on Arbitrum; the attacker laundered the majority of stolen funds through Tornado Cash. This was not the protocol's first security incident: its predecessor Visor Finance lost approximately $8.2 million to an infinite mint vulnerability in December 2021, leading to a rebrand.
