UniHooks

SlotMachineHook

BaseRegistered

A gamified hook that collects a configurable fee (default 2%) on all swaps via BeforeSwapDelta, splitting it into dual per-pool ETH jackpots. On qualifying ETH buys (above a configurable minimum), it triggers a slot machine spin for the buyer; winning combinations (pair, two-pair, three-of-a-kind, four-of-a-kind) pay out ETH directly. Sell fees are converted to ETH via a JackpotSellExecutor. Buyers receive SpinToken ERC-20 tokens for additional spins.

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.
