GweiFeeHook

EthereumRegistered

The single Uniswap v4 hook used by all gwei.fun launchpad pools. In `beforeSwap`, it deducts a configurable fee (platform fee plus optional per-pool creator tax with separate buy/sell rates and a linearly-decaying anti-snipe tax) from the specified currency via BeforeSwapDelta, routing proceeds to the creator's fee recipient and a GWEI buyback vault as ERC-6909 claims.

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.
