The spacepump
system

spacepump.fun is the sun in a play-to-launch solar system. Creator fees build a collective solar system payout pool. Every cash-out puts that planet on a pump.fun bonding curve on your behalf, and that coin becomes a unique planetary body in the system.

Your planet

Surface

The system

You start at 10,000 kg. A heavier planet is larger, but moves slower. Touching an asteroid or food absorbs its mass. You absorb another planet when yours is at least 15% larger and cover its center.

Your planet's surface is a terrain and a color. The Solana address sets the seed, so that address always has the same unique craters, bands, and storms. New surface types are unlockable based on gameplay and launch metrics.

Hold at least 1 $SPACEPUMP token in your wallet to cash out your planet after you fill the launch progress and you add it to the spacepump system as a unique tokenized planet.

Asteroid40,000 kg

Asteroid100,000 kg

Asteroids

An asteroid is 10,000 to 100,000 kg, and a heavier one is larger. Touching one absorbs its mass.

Eject15,000 kg

Eject

W ejects mass from your planet. Once your planet weighs at least 35,000 kg, it spends 18,000 kg to send out a 15,000 kg asteroid. That planet cannot pick it up for 0.4 seconds. Touching it after that absorbs its mass.

Comet100,000 kg

Comet

A comet is 100,000 kg. A planet swallows it from 132,000 kg up and adds those kilograms. The planet then bursts into more pieces, up to 16 in total.

SplitThe new half fires forward

Split

Space bar splits each piece in half once that piece weighs at least 35,000 kg, up to 16 pieces. The new half fires directly forward.

Cash outHold C for 10 seconds

Cash out

Holding C begins a cash-out. Hold it for 10 seconds and a single set of rings, in your planet's color, grows from you until it spans the entire game area. The cash-out completes only if you are not swallowed during that hold and hold at least 1 $SPACEPUMP token in your wallet. A death pays nothing.

What a cash-out is worth

= pool × min 1 , kg − 10,000 4,000,000 ^1.6 4

10,000 kg and under is worth nothing. The curve reaches a quarter of the pool at 4,010,000 kg, because the paid kilograms are the total minus the starting 10,000. The quote is refused under the launch minimum of 0.05 SOL .

Paying a cash-out leaves a smaller pool. The next cash-out is priced on what remains, so another cash-out at 4,010,000 kg takes a quarter of that smaller pool. Repeated full cash-outs shrink the pool toward zero. No single cash-out empties it.

Creator fees

Every buy and every sell on $SPACEPUMP pays a creator fee. Of the SOL that fee brings in, a share refills the pool the formula uses, a share is paid to the dev wallet, and a share buys and burns $SPACEPUMP.

Every launched coin pays creator fees too. Those fees are collected from each coin and split the same way. A coin that trades against SpaceX stock pays the fee in stock. That stock is swapped to SOL before the split. More trading and price action on any launched coin moves more into the system.

Launching your planet

The coin

It uses the planet's name, up to 32 characters, and the ticker is $SPACEPUMP. The custom token image and banner both show the unique planet from the run that launched the token into the $SPACEPUMP system. The banner also shows the name and the kilograms, and the mint once the coin exists.

SOL half Paid to you
This half stays in solana and is sent directly to the address you typed.

Launch half Swapped to SpaceX stock
This half is swapped from SOL directly into SpaceX stock, $SPCX.
New coin

Your planet $SPACEPUMP

The stock becomes the initial dev buy on pump.fun when your coin is created.
Automatically Transferred
The tokens from that dev buy on pump.fun are transferred directly to the same address that received the SOL.

The pair

The coin trades against SpaceX stock. That pairing is how a launch helps boost interplanetary exploration: the launch buy is a buy of the stock, and later trades move that pair. On the bonding curve the pool is the planet coin on one side and SPCX on the other. A buy spends stock and adds that stock to the pool. A sell pays stock back out of the pool.

Paired with SpaceX

Planet coins pair with SpaceX stock so every launch helps boost interplanetary exploration.

The loop

Refill the player pool, compounding future launches

01 · Launch Create a coin.

A qualifying cash-out launches the player's planet as a new token.

02 · Trade Trades earn fees.

All trades earn fees, on the main token and on launched planet coins.

Creator
fees

03A · Return Refill the pool.

Collected creator fees refill the player pool, supporting future launches. A share is paid to the dev wallet.

03B · Buyback & burn Supply gets smaller.

A share of the collected fees buys back the main $SPACEPUMP token and burns it.

Buys and sells on every launched coin pay creator fees. A higher price moves more SpaceX stock on the same trade, so the fee is larger. Fees from all of those coins are collected. Fees that arrive as stock are swapped to SOL. Trades on $SPACEPUMP are claimed the same way.

Some of that SOL comes back into the next cash-out. Some is paid to the dev wallet. Some buys $SPACEPUMP, and those tokens are burned. A burn removes them from supply. The next cash-out has more behind it, so another coin joins. Each turn adds a coin, pays more in fees, and leaves less $SPACEPUMP. A wallet needs at least 1 $SPACEPUMP to cash out and start the next turn.
