PhiEthHooksA 1:1 ETH/phiEth swap hook that implements a custom constant-price curve using beforeSwapReturnsDelta. It intercepts all swaps, converts ETH to phiEth (via deposit) or phiEth to ETH (via withdrawal) at a strict 1:1 rate, bypassing Uniswap concentrated liquidity entirely. Liquidity addition to the pool is permanently blocked.

AssetToAssetSwapHookForERC4626Periphery hook for pools using ERC4626 vault wrapper tokens. In beforeSwap, converts input ERC20 assets to vault wrapper shares, performs a nested swap in the corresponding vault wrapper pool via poolManager.swap(), then redeems output shares back to underlying assets. Handles both exact-input and exact-output swaps. Vault wrappers can be supplied via hookData or configured as per-pool defaults by the owner.
