SwingHook

EthereumRegistered

A Uniswap v4 hook for an ETH/SWING token pool that applies a custom fee delta in beforeSwap for buy-side trades, validates minimum output, and authorizes settlement in afterSwap. It supports standard Uniswap swaps and Swing-specific swaps that use randomness-based settlement through an external randomness manager.

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.
