GridHookA Uniswap v4 hook implementing per-user grid liquidity management. Users configure and deploy grid orders across price ranges; the hook tracks cumulative tick movement per block and reverts swaps that exceed a maximum price impact of 500 ticks per block to protect against excessive volatility.

AssetToAssetSwapHookForERC4626Periphery hook that automates asset-to-asset swaps for ERC4626 vault-backed pools. In beforeSwap, it converts the user's input asset into vault wrapper shares, performs a nested swap through a companion yield-harvesting pool, then redeems the output shares back to the underlying asset, returning the full delta so the pool itself executes no further swap.
