0x417c61c7796273b24f956d2cb29cbfc7e2e300ccBlockscoutA launch hook for WETH/token pairs that applies configurable protocol fees on buys (via beforeSwap delta) and sells (via afterSwap delta), denominated in WETH. An elevated 85% sniper fee is enforced during the first 30 seconds after pool registration. Pools must be registered by a designated factory contract; swaps on unregistered pools revert.

What it can do to your swap
- Can block swapsSwaps are gated (governance): only some addresses, or only at some times, can trade through it.
- Can take a fee from your outputAfter the pool fills your swap, the hook can keep part of what you were about to receive.
- Can change the price you getBefore your swap runs, the hook can take or add tokens, so the amount you get is set by its code as well as the pool.
- 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.
- Can charge a different fee on each swapThe pool's LP fee is dynamic: the hook sets it, swap by swap.
