BaseRegistered

A Uniswap v4 hook for ETH-paired pools that applies MEV-based swap taxes (scaled to gas priority fee) and protocol/creator swap fees, distributes rewards to in-range LPs via tick-based accounting, charges a JIT liquidity MEV tax on adds/removes, and supports a withdraw-only emergency mode controlled by an external factory owner.

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.

Takes a cut when LPs withdraw

It can change what LPs get back when they remove liquidity.

Adjusts deposit amounts

It can adjust token amounts when liquidity is added.

Runs at pool creation

It runs when a pool is created, often to lock in that pool’s settings.
