onuNativeTaxHook

RobinhoodRegistered

Charges an immutable native ETH tax on every swap in a single designated Uniswap v4 pool, deducting the tax from the native-token side via beforeSwap/afterSwap return deltas. Accumulated tax is held as ERC-6909 claims and forwarded to a fixed recipient once a fixed threshold is reached.

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.

Runs at pool creation

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