Forensic narrative

These implicit assumptions on Uniswap V2 resulted in 20 addresses on Alpha Homora V2 being impacted and lost a total of 40.93 ETH to miners who extracted this value. We have plans to compensate these 20 addresses. However, what’s more important is to share this with our community, especially other builders in the space to be aware of these implicit assumptions that are not stated, how you can detect this as a builder, and how to prevent/mitigate this. Attack method (per SlowMist): Sandwich attack. Reported loss: 40.93 ETH.
