PushBaseDynamicFeeHook

BaseRegistered

A Uniswap v4 hook that lets an off-chain keeper push dynamic LP fees (clamped to per-pool min/max bounds) with TTL-based expiry and automatic fallback to a configurable default fee. Additionally charges a hook fee to a treasury address on every swap via afterSwapReturnsDelta.

What it can do

Runs code on every swap

Its code executes inside each trade in pools that use it.

Can take tokens from swaps

It can take or add tokens during a swap. Fees, burns and custom curves work this way, and so do scams.

Sets its own swap fee

Pools using it let the hook choose the swap fee instead of a fixed tier.
