CrossPoolOracleHook

Cross-pool price oracle for manipulation protection

How it works

The hook reads the Reference Pool's price on every swap in the Protected Pool. If the swap's price impact can't be explained by market-wide movement in the reference pool, the fee increases or the swap is blocked entirely. No external oracle needed.

Demo Guide

Try a small swap (base fee), then a larger swap (elevated fee), and finally a large swap after moving the reference pool. The Event Log shows when dynamic fees or the circuit breaker are applied.
