StashHook

BaseRegistered

A Uniswap v4 hook that charges a flat 3% (300 bps) toll on the ETH leg of all four swap forms (exact-input and exact-output in both directions) in a single deployer-pinned pool, accumulating fees as ERC-6909 claims in the PoolManager. Anyone can call collect() to transfer the accumulated ETH fees to a fixed, immutable vault address set by the deployer.

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.
