sETH Hook

BaseRegistered

A Uniswap v4 hook that wraps and unwraps Superfluid's native asset SuperToken (SETH/ETHx) at a 1:1 ratio. It intercepts swaps via `beforeSwap` to perform ETH→ETHx wrapping or ETHx→ETH downgrading directly, returning a `BeforeSwapDelta` to handle pool accounting. Direct liquidity operations are blocked.

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.

Gates who can add liquidity

It checks every deposit before it goes in.

Runs at pool creation

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