0x47a9a2c1eaca6974e36c00c6993e1ccd2f0600ccBlockscoutA volatility-sensitive fee hook for native ETH/token pools that collects ETH fees (1%–7.3%) directly via BeforeSwapDelta on buys and AfterSwapDelta on sells. The fee scales between a configurable base and maximum based on the previous swap's tick movement. Exact-output swaps are blocked; only exact-input swaps are permitted.

What it can do to your swap
- Can block swapsSwaps are gated (other): 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.
