Send it to holders
Launch a coin on pump.fun and split its fees between yourself, its holders, buyback and burn, liquidity and other wallets
Payments run by themselves, and every change waits in public
Six answers to “where does the fee go?”
Pick one, or blend all of them. Each line on the split is its own payout.
To you
Your share lands in your wallet by itself as trades come in. No claiming, no dashboard to babysit.
To holders
Every holder earns by how much of the coin they hold, and claims it when they like.
Into buyback and burn
The coin buys itself back and burns it, on the curve or in the pool.
Into liquidity
After graduation it deepens the PumpSwap pool, and that liquidity is locked in the vault.
To other wallets
Up to six addresses: a co-founder, an artist, a charity, a treasury.
Any mix of them
Shares in steps of 0.01%, adding up to 100%. Change it later, in public.
One trade, followed to the end
Each buy or sell on pump.fun pays a creator fee. pump.fun sends 3% of it to FeeOS and the rest to the coin's vault, and the vault pays out by the coin's split. Nobody has to press a button.

How the split stays honest
Three rules the program enforces, and the numbers they have moved so far.
Fees can only reach the split
At launch the coin's creator fees are locked to its vault on pump.fun, and the right to redirect them is given up for good.
Every change waits 24 hours in public
A new split shows on the coin's page the moment it is proposed. The current one holds until the timer ends.
Old money goes by the old split
What reached the vault before a change is divided by the rules that were in force when it arrived.
Paid so far
What FeeOS can still do
- Upgrade the program
- List holders for claims
- Set price limits on buybacks
- While launches are paused, wind a coin down, which sends its vault to its creator
What FeeOS cannot do
- Send a vault anywhere but its split
- Change a coin's split
- Skip or shorten the 24 hours wait
- Take more than its 3% share
pump.fun, with and without FeeOS
Same curve, same pool, same trading. The difference is what happens to the fee.
Questions people ask first
pump.fun pays the coin's creator a small cut of every buy and sell. On FeeOS that cut doesn't go to a wallet. It goes to the coin's vault, and the split sends it on.
No. At launch the right to redirect the coin's fees on pump.fun is given up for good, so the vault is the only place they can arrive, and the split is the only way out.
Never faster than 24 hours. A new split shows on the coin's page and on the Changes page the moment it is proposed, with a timer. The creator can cancel it, but nobody can make it shorter.
Their share builds up from every trade. FeeOS lists every holder's amount on chain, and each holder claims it from the coin's page when they want. Nothing is lost by waiting.
0.01 SOL to launch, and 3% of every creator fee before the split. There is no other charge.
Your coin. Your rules for every fee.
Launch on pump.fun with a split that runs itself from the first trade.
