# Welcome to 2hour.fun

> A launchpad on Robinhood Chain and Solana where every new coin launches in the same 2-hour window each day.

2hour.fun is a place to create and trade new coins on **Robinhood Chain** and **Solana**, side by side, with the same rules on both.

Trading never stops. What's different is **launching**: new coins can only be created during one **2-hour launch window** each day. Every launch lands in the same window, in front of the same crowd, with a fair shot at attention.

## How it works

**1. The window opens**

Once a day, for 2 hours, anyone can launch a coin on either chain. The countdown in the site's top bar shows when.

**2. Coins start on a bonding curve**

Every coin starts with a fixed supply on a curve. Buys push the price up and sells bring it down.

**3. Trading runs around the clock**

Every coin can be bought and sold 24/7, on both chains, whether the window is open or not.

**4. Graduation**

When a coin's curve fills, it moves to a Uniswap pool (Robinhood Chain) or a Raydium pool (Solana), and its liquidity is locked for good.

## Why a launch window?

* **Attention in one place.** Launches are grouped together, so each coin gets a real share of attention instead of being lost in a non-stop stream.
* **Fewer, better launches.** One window a day and a \$500 launch fee make low-effort copies of other people's coins far less rewarding.
* **Calmer for newcomers.** There's a clear time when new coins appear.
