How it works.

What it does

You launch a coin on pump.fun through Tickover. Half of its creator fee goes to you, as usual. The other half goes to an engine wallet made for that coin alone, and every minute the engine spends what's there buying your coin back.

Those buys are made by the engine with fee money. They aren't outside demand, and they're labelled as the engine's everywhere on this site.

Launching

Your wallet signs one thing: a plain SOL payment to a wallet made for this launch. Nothing else is ever asked of it.

1. Fill in the form. The launch is simulated on pump.fun before you're asked for anything.
2. Approve the payment: 0.04 SOL plus your dev buy and a 3% margin on it.
3. The launch wallet creates your coin and locks the split, in one transaction.
4. 0.005 SOL of your payment goes to the coin's engine wallet, for its rent, its token account and its first network fees.
5. Your dev-buy tokens and every lamport the launch didn't use come back to your wallet.

If pump.fun refuses the launch, everything you sent goes back. A closed tab changes nothing: the engine finishes the launch either way.

The split

pump.fun's fee-sharing program holds the split: 50% to the wallet that launched the coin, 50% to the coin's engine wallet. It's set in the same transaction that creates the coin and locked for good. Nobody can change it afterwards, including us.

The minute

1. Claim. Once at least 0.01 SOL of creator fees is waiting, the engine claims it. One claim pays both shareholders, so your half reaches your wallet at the same moment.
2. Measure. It reads what the coin's engine wallet can spend: its balance, less rent, and room for this cycle's network fees.
3. Buy. Up to 5 equal buys, 5 seconds apart. No buy is under 0.0025 SOL; smaller amounts wait for the next cycle.
4. Log. Every buy goes in the engine log with its transaction.

A new cycle starts 60 seconds after the last one started, and never while one is still running. Coins buy on the bonding curve, then on PumpSwap after graduation.

Engine wallets

Every coin has its own. Its share of the fees lands there, its network fees are paid from there, and its buys come from there. No coin's SOL can reach another coin's buys, because it never sits in the same wallet.

What it buys stays in that wallet. The engine has no code that sells.

What to know

• The split is enforced by pump.fun. The buying is done by Tickover's server, which holds each engine wallet's key. If the server stops, buys stop, and the coin's fees wait to be claimed.
• No trades means no fees, and no fees means no buys.
• A buy that would fill more than 5% worse than its quote doesn't go through. Its SOL stays for the next cycle.
• pump.fun can change its programs or fees.
