JBUniswapV4Hook

EthereumRegistered

A Uniswap V4 hook that routes exact-input swaps to either the V4 pool or a Juicebox project terminal, choosing whichever venue offers more output, using a 30-minute TWAP oracle for manipulation-resistant comparison. Also maintains a TWAP oracle ring buffer queryable by external contracts such as buyback hooks.

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.
