RobinhoodRegistered

A fixed-fee hook for ether-quoted "Instant" launch markets that charges 1.50% on every swap's ether leg (1.00% to the market creator, 0.50% to the platform), using BeforeSwapDelta and afterSwapReturnsDelta to collect fees across all swap directions, while setting the pool LP fee to zero.

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.

Sets its own swap fee

Pools using it let the hook choose the swap fee instead of a fixed tier.

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.
