Your coin launches with its own market maker. It sells into every pump, buys the dips back and pays holders — run by a Solana program, not by a promise.
Inventory, treasury and liquidity sit in program accounts. The creator cannot pull them before the lock ends.
Each sell, buyback and payout is a transaction anyone can open and check.
A slice of every net buy is sold; dips are bought back, harder the deeper they go.
The pump.fun creator fee goes to holders, without anything to claim by hand.
Shape of a launch: the bot sells into the rises and buys the dips back.
Every buyback and every sale the market makers execute, on every coin, as it lands on-chain. Each line is a transaction you can open.
No bot trade on the tape yet. It starts with the first net buy on the first coin.
At readable speed. Every bid below is sized by the same rule the on-chain program runs — this is the mechanism, not an illustration of it.

1NowBuyers push the price up. The bot sells a small slice of every net buy into that strength — never the other way round.
2Every sale lands in the treasury. It is locked inside the program: nobody can withdraw it, its only job is buying the coin back.
3The price falls under what the bot sold at. The deeper the dip, the bigger the bid — and never more than half the treasury, so it can bid again.
4Bought-back tokens return to the inventory and are sold into the next rise. The cycle compounds, and holders are paid along the way.
The same program, read from the side of the person who launches and from the side of the person who buys.
Start small to see it work, or go big. Same mechanics, different power.
Launch a real coin with its own market maker from ~0.1 SOL. You choose the size, from 0.1% of the supply, and see the bot sell, buy back and pay holders before committing more.

The questions a careful buyer asks before touching a new coin, answered without the sales voice.
The market maker's inventory, its treasury and the locked liquidity are held by the program, not by the creator's wallet. While the lock runs the creator cannot move any of it, and with “locked forever” they never can. What a creator owns is what they bought on the curve, like anyone else.
From its own sales. It sells a small slice of every net buy, and those proceeds fill the treasury. The treasury has a single job: buying the coin back. There is no outside funding and no hidden wallet — every movement is a transaction you can open.
Selling stops and the treasury bids. The size of the bid follows how far the price has fallen under the bot's own average selling price: a shallow dip gets a small bid, a deep one gets up to half the treasury. Never more than half, so there is always money left for the next leg down.
From the pump.fun creator fee. On a SOL launch the coin is a pump.fun holder-rewards coin, so pump.fun sets the fee of every trade aside and pays holders itself. There is nothing to claim by hand.
You pay for the tokens the market maker will hold (bought on the curve like any buyer), the SOL side of the locked liquidity, and a 1% platform fee. The quote is itemised before you sign, and the transaction refuses to execute if the real cost ends up more than 1% above it.
Yes. Pick USDC, or another token pump.fun admits, as the quote asset in the launch wizard: the curve, the treasury and the rewards are then all in that token.
Not yet. It is tested end to end against the real pump.fun programs, and an independent audit is planned before the public opening. Until then, size your launch accordingly.
Pumpmaker gives creators and communities a stronger foundation. Not just a launchpad: an on-chain layer under the coin.
