UnichainRegistered

Charges a time-decaying fee on swaps (starting at 26%, decreasing by 200 bps every 25 blocks until it reaches 0%) and 100% on WETH. In afterSwap, collects fees from the output token, swaps non-ETH fees back to ETH via a nested pool swap, and forwards all ETH fees to a designated fee address.

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.
