# Fees

> Fee structure for token creators and traders on makx.io — hook fees, LP fees, and protocol cuts.

## Fee overview

Makx pools have two independent fee layers. Both are charged on ETH (the base currency of every pool).

***

## LP fee

**Fixed at 0.3%** per pool, set at pool initialization and never changed. Goes entirely to liquidity providers — including the vault's LP position. The hook contract overrides this value on every swap to ensure it stays consistent.

***

## Hook fee

Set by the token creator at launch via `hookFeeBps`. Charged as a flat bps fee on ETH on every swap:

* **ETH → Token:** Deducted from ETH input before reaching the pool. Pool only sees `ethIn - hookFee`.
* **Token → ETH:** Deducted from ETH output before the trader receives it.

Hook fees accrue in `launchFeeBalance` and are claimable by the creator via `claimFees()`.

The creator can update their `hookFeeBps` at any time by calling `setHookFee(launchId, newBps)`. The protocol caps the maximum at `maxHookFeeBps`.

***

## Protocol cuts

The protocol takes a share of several actions:

| Action                  | Parameter                | Who pays      |
| ----------------------- | ------------------------ | ------------- |
| Hook fee claim          | `adminFeeBps`            | Token creator |
| LP fee collection       | `adminCollectLpFeeBps`   | Token creator |
| Rent deposit            | `adminPayRentFeeBps`     | Token creator |
| Liquidation surplus ETH | `adminLiquidationFeeBps` | Liquidator    |
| Vault deposit           | `feeBps` (vault)         | Depositor     |
| Vault redeem            | `feeBps` (vault)         | Withdrawer    |

All protocol fee parameters are denominated in BPS and configurable by the protocol owner. The vault fee is capped at 1000 BPS (10%).

***

## Claiming fees

While the launch is `Active` and **outside the grace period**:

```solidity theme={null}
// Claim accumulated hook swap fees
claimFees(uint256 launchId)

// Collect Uniswap V4 LP trading fees
collectLPFees(uint256 launchId)
```

Fee claims are blocked once the launch enters the grace period. Accrued fees are preserved during the grace period — they are not lost. Once the launch is extended past the grace period, claims resume.

If the launch is liquidated without the creator reclaiming fees, all accumulated hook fees go to the liquidator.

***

## Rental fees

Rental is not a "fee" in the traditional sense — it is the cost of borrowing ETH liquidity. See [Launch a Token](/launchpad/launch-token) for how `feePerSecond` and `bondAmount` are calculated.

```
feePerSecond = bondAmount × feeRateBps / 10_000 / annualizedBasis
```

Rental payments flow to the vault as interest, raising the share price for METH holders.
