tldr: Delta Neutral is a self hosted Rails app that allows you to enter hedge configurations for your Uniswap v3 positions. You enter a target hedge, i.e. 50%, and accordingly shorts are opened on Hyperliquid. As your assets composition changes in the pool, your shorts will be rebalanced to stay at your target hedge.

Here's the code: https://github.com/carter2099/delta_neutral

It builds on my Ruby Hyperliquid SDK: https://github.com/carter2099/hyperliquid
