What is ubi.fun?
Launch a coin in one click. Every trade pays holders daily in on-chain USDC.
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 holder income, the “UBI” in the name, and it is ubi.fun’s own invention, designed and built for this platform: 24% of every trading fee funds a shared holder pool, paid out daily in USDC. Hold a coin people trade, and you earn USDC for holding it. No staking, no lockups, no extra steps. ubi.fun is the first launchpad where simply holding earns USDC.

The economics in one line
Every swap pays a 1.25% fee. Per $10M of trading volume, 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 team | $18,750 | 15% |
| Whoever referred the volume | $6,250 | 5% |
The 24% holder share is enforced in bytecode. Nobody can redirect it, including us. The full picture lives in Where every fee goes.
