Angstrom Hook

BaseRegistered

A Uniswap v4 hook that implements MEV-aware swap and liquidity taxes, distributing fees between the protocol, pool creator, and LPs via return deltas. Includes a governance-controlled withdraw-only mode that blocks new swaps and liquidity additions.

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.
