# Launch a Token

> Step-by-step guide to launching a meme coin on makx.io using the liquidity rental model.

## Before you start

You need ETH to cover two things:

* **Rental payment** — pays for the minimum rental duration on your chosen bond amount.
* **Dev buy** (optional) — ETH to buy tokens at the launch price immediately.

`msg.value = rentalPayment + devBuyETH`

***

## Step 1 — Choose a market cap

The makx.io UI lets you pick a target market cap. Behind the scenes this determines your `bondAmount` — the ETH that will back your Uniswap pool.

```
bondAmount = rentalPayment / (feeRateBps × minRentalDuration / 10_000)
```

Larger market cap → larger `bondAmount` → larger rental payment.

***

## Step 2 — Set your hook fee

The hook fee (`hookFeeBps`) is a flat bps fee taken from every ETH swap on your pool. It accrues to you (minus a protocol cut) and is claimable at any time while your rental is active and outside the grace period.

You can change `hookFeeBps` at any time after launch by calling `setHookFee()`.

Maximum hook fee is capped by the protocol's `maxHookFeeBps`.

***

## Step 3 — Launch

Call `createToken(name, symbol, duration, devBuyETH, hookFeeBps)` with the correct ETH value. Everything happens atomically:

1. Token contract is deployed (gas-efficient clone, 1B supply, no mint function).
2. Makx borrows `bondAmount` ETH from the vault.
3. All 1B tokens + `bondAmount` ETH are added as a full-range Uniswap V4 LP position.
4. The LP NFT is held by the MakxYieldPad contract.
5. Your dev buy executes at the launch price.
6. Pool is registered and hook fee takes effect immediately.

***

## After launch — managing your rental

### Extend rent

Call `depositRent(launchId)` with additional ETH at any time while you are **outside the grace period**. Extra seconds are calculated at the current `feeRateBps` on your current `bondAmount`.

Extensions are blocked once you enter the grace period — you must stay ahead of it.

### Repay the bond

Call `repayBond(launchId)` to return borrowed ETH directly to the vault. This reduces `bondAmount`, lowers your `feePerSecond`, and reduces ongoing rent burden. If you repay the bond fully, the launch transitions to `Repaid` status — no further rent is ever owed.

### Claim fees

While the launch is active and outside the grace period:

* `claimFees(launchId)` — claims accumulated hook swap fees (minus `adminFeeBps` cut).
* `collectLPFees(launchId)` — collects Uniswap V4 LP trading fees (minus `adminCollectLpFeeBps` cut).

## Token contract properties

| Property                 | Value                                       |
| ------------------------ | ------------------------------------------- |
| Total supply             | 1,000,000,000 (fixed, no mint post-launch)  |
| Implementation           | Gas-efficient clone of `MakxTokenCloneable` |
| Tokens in pool at launch | 100% of supply                              |
| Tokens held by protocol  | None                                        |

## What you earn

| Fee type        | When earned                 | Claimed via       |
| --------------- | --------------------------- | ----------------- |
| Hook swap fees  | Every ETH swap on your pool | `claimFees()`     |
| LP trading fees | Every swap (0.3% LP fee)    | `collectLPFees()` |
