Mint your star
Mint one for free and a single glowing star appears, ready for planets to orbit. Your first system costs nothing beyond the usual Ethereum network fee.
Three calm steps, then it lives on its own.
There is nothing to study and nothing to rush. You mint a star, add a few planets, and set their orbits. Here is the whole of it, start to finish.
Add a few planets
Choose from nine kinds of planet, set each one an orbit, and pick its colors and rings. Every choice is written straight to the token, so your system is one of a kind.
Let it live on chain
From then on it animates on its own, stored on Ethereum and drawn fresh every time someone views it. There is nothing to maintain and no renewals, so it simply keeps going.
Seven kinds of star
It begins with the light at the centre.
Every system is lit by one of seven classes of star, from a cool red ember to a rare blazing blue. The class sets the mood of the whole piece and how the planets are lit.
MRed ember
KWarm amber
GSun-like
FSoft white
AClean white
BBlue-white
ORare blue
Nine kinds of world
Then you choose what to put around it.
Each planet you add is one of nine types. Mix them freely, give them the orbits you like, and no two collections ever end up quite the same.
Terran
Hills and oceans, a world you could picture walking on.
Ocean
Water from pole to pole, calm and reflective.
Desert
Dry and dune covered, warm in the starlight.
Barren
Bare rock and craters, quiet and still.
Glacial
Locked in ice, pale and very bright.
Gas
A banded giant with no solid ground at all.
Azure
A vivid world wrapped in thick, bright air.
Molten
Young and restless, still glowing from within.
Violet
Strange skies and unusual chemistry, one of the rarer kinds.
As it grows
The care you give it is remembered.
Every bit of ETH you add to your system is saved on the token as a score called Gravity. It only ever goes up, and it travels with the piece when you sell, so a system carries its whole history with it.
