What is ubi.fun?
Launch a token in one click on Arc. Trading fees are split on chain between creators, holders and the protocol.
ubi.fun is a coin launchpad on Arc, the USDC-native chain by Circle. Anyone can launch a coin in seconds and trade it from the first block on a real Uniswap v4 market. What makes it different is where the trading fee goes: most of every fee flows back to the coin’s economy, including its creator, holders, and price floor, instead of to the platform.
The headline mechanic is the holder pool, the “UBI” in the name, and it is ubi.fun’s own invention, designed and built for this platform: a share of every trading fee, from every coin (24% on coins launched before v2, 13% on v2 tokens (1.5% to 5% fee)), funds a shared pool that a published formula splits each day among eligible holders of UBI, the platform coin, paid in USDC. What the pool holds depends entirely on trading activity, so a day’s payout can be small or nothing.

The economics in one line
Every swap pays one fee: 1.25% on tokens launched before v2, and 1.5% to 5%, chosen at launch, on newer tokens. Per $10M of trading volume at 1.25%, that fee splits into:
| Where it goes | Per $10M traded | Share of the fee |
|---|---|---|
| The coin’s creator (and their buyback, by their chosen split) | up to $70,000 | 56% |
| All holders, via the daily USDC pool | $30,000 | 24% |
| The protocol | $18,750 | 15% |
| Whoever referred the volume | $6,250 | 5% |
The 24% holder share is enforced in bytecode: nobody can redirect it before it reaches the pool, including us. Tokens launched with a creator vault also pay their own holders, and from October 7, 2026 their fees split 77% to the creator side, 13% to UBI holders and 10% to the protocol, see Creator vaults and holder dividends. The full picture lives in Where every fee goes, and the same trade on another launchpad, read from both sets of contracts, is in How ubi.fun compares.
