JBUniswapV4Hook

ArbitrumRegistered

Routes exact-input swaps to whichever venue—Uniswap V4 pool or Juicebox project terminal (pay/cashOut)—offers the best output, using a 30-minute TWAP oracle for price-manipulation resistance. Also implements IGeomeanOracle so external contracts (e.g. buyback hooks) can query this pool's TWAP.

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.
