How it works

What a launch does

Every project here launches through Classic: a factory contract on Robinhood Chain that, in one call, deploys a fixed-supply ERC-20, opens a Uniswap v4 pool quoted in ETH, puts the entire supply into that pool as one locked position, and optionally executes the creator’s first buy at the opening price before anyone else can trade.

• Supply. 1,000,000,000 tokens, always. No creator allocation, no team tokens, no vesting. The creator owns exactly what they buy.
• Liquidity. The whole supply is the pool. The position cannot be withdrawn by anyone, including us. There is no “rug” path in the contracts.
• Immutability. Name, ticker, image and description are written into the token at launch. The fee terms are fixed in the market’s vault. There is no admin key that can pause trading, change fees, mint supply or edit the metadata.
• Who launches. The creator’s own wallet signs and pays gas. v4.fun holds no key and cannot launch, trade or claim on anyone’s behalf.

Vetted and permissionless

Both lanes use the same contracts, the same fees and the same locked liquidity. The difference is one fact about the people, not the market.

A wallet becomes vetted after its team applies and we have talked. Every market that wallet has launched or launches afterwards sits in the vetted lane. A vetted team gets a profile — header, tagline, go-live date, links — that sits on top of what the chain says, and never replaces it.

Fees

Every buy and sell pays two fees, both taken in ETH and both fixed at launch.

Creator fee

Chosen by the creator, from 0% to 5% of every trade. Paid to the creator’s wallet in ETH, not in their own token, and claimable from their project page at any time. The default is 1%.

Platform fee

0.5% of every trade, on top of the creator’s fee. It funds v4.fun. It is not a choice in any generation and the creator never pays it.

Launch cost

Gas, plus whatever first buy the creator asks for. There is no listing fee, no creation fee and no cut of the supply.

Where the creator fee can go

A creator can commit a share of their fee to buying their own token and burning it, and a share to paying holders. Both shares can be raised later — never lowered — so a promise made to holders holds.

Project pages

Every market gets a page the moment it exists: chart, trades, market cap, fees earned, the description and links written at launch, and every address involved. It is the same page for every project, vetted or not, and it reads the chain and the indexer live — nothing on it is cached or estimated, and where a figure cannot be had the page says so instead of showing a zero.

Vetted teams can add to their page: a header image, an avatar, a tagline, an “about” section and a planned go-live date — which lets a project appear on the launchpad before its token exists. Nothing a team adds can override a fact the chain holds.

For traders

Every market here can be traded from its page with any wallet on Robinhood Chain. Prices are Uniswap v4 prices; there is no order book and no counterparty but the pool. Because the whole supply starts in one position, early prices move a great deal on small trades, and slippage at low liquidity is real. The page shows the fee you will pay before you sign.

Tokens launched here are created by their creators, not by v4.fun, and can lose their entire value. A vetted badge means we know who launched it. It does not mean it will go up.
