Unlisted hook

What it can do to your swap

• Its code can be replacedThe hook is a proxy (EIP-1967). Whoever controls it can swap in new code, so what it does today is not a promise for tomorrow.
• Runs code before your swap and can block itThe hook is called before every swap. It can revert, which makes your swap fail.
• Runs code after your swap and can block itThe hook is called after every swap. It can revert, which undoes your swap.
• Runs code when a pool is createdCalled once, when someone creates a pool with this hook.
• Runs code after a pool is createdCalled once, right after a pool with this hook is created.
• Can charge a different fee on each swapThe pool's LP fee is dynamic: the hook sets it, swap by swap.
