Fees and creator rewards

There are two fees, and they are unrelated. A one-off fee to create a coin, and the pool's own trading fee that is shared with the creator for as long as the coin trades.

Creation fee

Charged once, when you launch, in the network's native token. It is set per network and the platform can change it, so rather than print a figure that would go stale, this page asks each launch contract directly:

NetworkCost to launch
Reading from the launch contracts…

Read live from each network's launch contract when this page loaded. Gas is separate and goes to the network.

It is shown in the app again before you sign, and it is not refundable once the transaction confirms. Gas is separate and goes to the network, not to us.

What “Free” means

A network showing Free costs nothing but gas to launch on. Everything else is unchanged — the same liquidity is created and permanently locked, and the creator earns the same share of trading fees. A free launch is a promotion on the one-off fee, not a different kind of coin.

Trading fee

90%of every trading fee, to the creator on Uniswap V4

On Uniswap V4 pools — Arc, Robinhood Mainnet and Base — the creator keeps 90% of the whole fee and the platform keeps 10%. On V3 pools the creator keeps 100% of the coin side and 50% of the quote side — roughly three quarters of the value at an even mix of buying and selling. Both are set on the factory and readable on chain.

Every swap pays the pool's fee — the percentage shown on the trade panel. This is collected by Uniswap into the position, not taken by Muup.fun, and it is split when it is claimed.

How it is split depends on which pool your coin trades in. The coin's own page names its venue, and the launch panel names it before you sign — so if you only want the number that applies to you, find your network here:

Uniswap V4 pools

V4 pools pay the creator 90% of the whole fee — the platform keeps 10% — rather than splitting the two sides on different terms. There is no asymmetry to reason about here: ninety percent means ninety percent of everything the coin earns.

A V4 pool divides the whole fee once. There is no second side on different terms.

Where that fee is taken from depends on whether the network runs the quote-fee hook:

  • With the hook — Arc and Robinhood Mainnet — 1% is taken from the quote side of every swap, outside the pool. Fees therefore reach you in the quote asset only, never as your own coin, whichever direction the trade went.
  • Without the hook — Base — nothing is taken outside the pool. Fees accrue in the liquidity position and arrive in both tokens, the same way a V3 position does. The split follows: you keep 90% of the quote side and all of the coin side, which is nearer 95% of the total at an even mix and never below 90%.

A creator may also charge their own tax, and give their fees to holders

Everything on this page is the standard arrangement. Two optional extras change it: a trade tax of up to 10% that a creator adds on top and keeps entirely, and holder fee sharing, which hands the creator's whole share to the people holding the coin. Both are set once at launch and are disclosed on the coin's own page. See Trade tax and holder rewards.

Fee collection on Base is manual for now

The scheduled collector that sweeps fees automatically only covers V3 positions. On Base you claim from the coin's fee card yourself; nothing is lost by waiting, since the fees accrue in the position until they are collected.

Uniswap V3 pools

V3 is the older arrangement, and the only one on Stable. It has the asymmetry V4 removes: the pool accrues fees on both sides of the pair — a buy pays its fee in the quote token, a sell pays its fee in the coin itself — and the two sides are split on different terms.

A V3 pool collects fees on both sides of the pair. The two sides are split differently.
Fee sideCreatorPlatform
Quote token (from buys)50%50%
The coin itself (from sells)100%nothing

Across a normal mix of buying and selling that works out to roughly three quarters of the total fee value going to the creator. The platform's quarter is always in the liquid quote token rather than in coin dust, which is the reason the split is shaped this way rather than being an even cut of everything.

Why a fixed share rather than a valued one

Splitting by a fixed percentage of each side, instead of valuing the coin side at the current price, is deliberate. Claiming is permissionless — anyone may trigger it — so a price-dependent split could be skewed by moving the pool price inside the same transaction.

Claiming

  • Fees accrue in the position and are claimed, not streamed. They do not expire.
  • Your dashboard and your profile both show what is currently claimable for each coin you created.
  • The payout address is yours to change and only yours: the wallet credited as creator is the only one that can point it somewhere else. The platform cannot redirect it.
