# Hand the concentrated liquidity factory to the protocol fee setter

This referendum moves ownership of Hydration's concentrated liquidity pool factory to a small purpose-built contract, the protocol fee setter. That lets the standard protocol fee be switched on for every pool, current and future, without a separate referendum each time.

## Why

The factory owner is the only account that can set a pool's protocol fee. Today that owner is governance itself, so every new pool needs its own referendum just to turn the fee on. The four pools launched alongside HOLLAR (atBTC, aPAXG, GETH and GSOL) are live but not yet collecting the protocol fee.

## What the fee setter does

- Anyone can call it to set a pool's protocol fee to 1/4 of the swap fee, the same setting the aDOT/HOLLAR pool already uses. It only accepts pools created by our factory, and it can only set this one value.
- Anyone can call it to sweep a pool's collected protocol fees, and those fees can only go to the Hydration treasury.
- Governance keeps full control. Only governance can send fees anywhere else, and only governance can move factory ownership again, including taking it back at any time.

Once this passes, the protocol fee on atBTC, aPAXG, GETH and GSOL can be switched on with an ordinary transaction, and later pools get it the same way.

## The call

One EVM call, dispatched as governance's EVM account: factory.setOwner(0x0B3f5231f26ee9b5553EeF6E6147Cd660bc6ecA3)

# Hydration Protocol Fee Setter

Hydration is a system that has pools where people swap tokens. This page is about a vote to make fees easier to turn on.

- Right now, turning on a fee for a pool takes a whole new vote each time. That is slow.
- The vote hands the pool factory to a small helper contract called the **protocol fee setter**.
- This helper can turn on a fee for any pool, old or new.
- The fee it turns on is always **1/4 of the swap fee**. It cannot pick other amounts.
- Anyone can use it to turn on fees or send fees to the Hydration treasury.
- The four new pools (atBTC, aPAXG, GETH, GSOL) can then start collecting fees.
- Governance still stays in charge and can take the factory back whenever it wants.
