Launch a coin that trades on Uniswap from second zero.
No liquidity to provide, no presale, no team allocation. You pay a flat service fee — the entire supply goes straight into a Uniswap V4 pool.

What it is
cook4.fun is a token launchpad on Robinhood Chain. When you launch a coin, it is immediately live and tradeable on Uniswap V4 — there is no bonding-curve phase to sit through and no “graduation” to wait for.
The trick is that the coin's entire supply is deposited into the pool as one-sided liquidity. Because the pool starts with tokens on one side and zero ETH on the other, nobody has to seed it. You don't bring liquidity; you just pay the service fee. As people buy, ETH accumulates in the pool and the price climbs.
Getting started
You need a wallet and some ETH on Robinhood Chain.
- 1Connect your walletMetaMask, Coinbase Wallet, or any WalletConnect wallet. cook4.fun will switch you to Robinhood Chain automatically.
- 2Bring ETH acrossUse the Bridge ETH link in the sidebar. Gas on Robinhood Chain is cheap, so a small amount goes a long way.
- 3Launch or buyCreate your own coin, or buy one from Discover.
Launching a coin
Fill in a name, ticker, image and links, then hit launch. You pay 0.001 ETH and nothing else. In a single transaction, cook4.fun mints 1,000,000,000 tokens, creates the Uniswap V4 pool, and deposits the whole supply into it.
Starting market cap
Every coin opens at the same place: a market cap of 1.5 ETH. That figure is fixed in ETH — it is baked into the launch price and is identical for every coin, forever.
The dollar number you see on the site is just that ETH figure converted at the current ETH price, so it drifts as ETH moves. Nothing about the coin changes — only the price of ETH does.
| If ETH is | Launch market cap (1.5 ETH) |
|---|---|
| $1,500 | ≈ $2.3K |
| $2,000 | ≈ $3.0K |
| $3,000 | ≈ $4.5K |
| $4,000 | ≈ $6.0K |
Optional first buy
You can buy some of your own coin in the same transaction that launches it. This is the only way to get tokens before anyone else — there is no presale and no allocation set aside for the creator.
The liquidity position is owned by the cook4.fun contract, not by you. That means the creator cannot pull liquidity out from under holders.
Trading
All trading happens in the coin's Uniswap V4 pool. You can buy and sell from the coin's page on cook4.fun, or trade the pool directly on Uniswap — it is the same pool and the same liquidity either way.
Every swap pays a 1% fee, which is where creator and holder rewards come from. The chart on each coin page is built from real pool trades and updates live as people buy and sell.
Rewards coins
When launching, a creator can turn on rewards. On a rewards coin, the creator gives up their share of trading fees and it is paid out to holders instead, split in proportion to how much of the coin each wallet holds.
Rewards are paid in ETH. Open the coin's page and press Claim to collect yours. Claiming also sweeps in the newest fees — including from trades made directly on Uniswap — so you always collect your full share.
Coins with rewards enabled are marked with a REWARDS badge on Discover.
Fees
There are only two: a flat fee to launch, and the 1% swap fee that Uniswap charges on every trade.
| Fee | Amount | Who receives it |
|---|---|---|
| Launch | 0.001 ETH | cook4.fun |
| Swap — protocol | 0.25% | cook4.fun |
| Swap — creator | 0.75% | The creator, or holders on a rewards coin |
The two swap rows are the split of the single 1% fee — a trade is never charged twice.

FAQ
Do I need to provide liquidity?+
No. The coin's own supply is the liquidity. You pay the 0.001 ETH service fee and nothing more.
Is there a graduation, like on other launchpads?+
No. There is no bonding-curve phase and no migration step. The coin is on Uniswap from the moment it launches.
Can the creator rug the liquidity?+
Not the pool liquidity. The Uniswap position is held by the cook4.fun contract, so the creator has no way to withdraw it. A creator who does a first buy can of course sell those tokens, like any other holder.
Is there a team allocation or presale?+
No. The full 1,000,000,000 supply goes into the pool at launch. The only way a creator can get tokens early is the optional first buy, paid for at the launch price like everyone else.
Why does the launch market cap in dollars keep changing?+
Because it is fixed in ETH, not dollars: every coin opens at exactly 1.5 ETH. The dollar figure is only that amount converted at the current ETH price, so it rises and falls with ETH. The coin itself is unchanged.
When do holder rewards show up?+
Fees build up in the pool and are shared out whenever someone trades on cook4.fun or claims. If a coin has only been traded directly on Uniswap for a while, your on-screen balance may lag — pressing Claim pulls in everything owed to you.
