YoyoStrategyHook

UnichainRegistered

A fee-taking hook that charges a time-decaying fee (starting at 26%, decreasing 200 bps every 25 blocks) on all swaps, taken from the output token via afterSwapReturnsDelta. When the fee currency is WETH, a 100% fee is applied instead. Non-ETH fees are converted to ETH via a nested pool swap and forwarded 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.
