ACCRETION
A 3D world you own on Ethereum, drawn by code inscribed on Bitcoin. It changes with every block, and you can spend what it grows.
No server. No IPFS. Leveraging Bitcoin.
The renderer is one recursive Ordinal on Bitcoin. Every trait is a value on an Ethereum contract. tokenURI assembles the URL and that is the whole pipeline.
The chain moves. So does the art.
One number. You can spend it.
Every monolith rises at the same rate, so age alone never separates two pieces. What separates them is what they did with it.
Spend height. Build one tall thing.
Pick one piece as your Core. Lock others around it. They pour their height in and get visibly shorter. The Core rises.
Every orbit ends in a draw.
Odds are priced per metre of height the orbit consumed. Spend more, draw better. One roll can pay more than one of these, and none of them has a purchase price.
And a dry run is not a wasted one. Alongside the draw, every piece hits milestones: a guaranteed grant for every twelve metres it has poured over its life, starting at three. Those always pay a companion you do not already have, so orbiting builds a collection whether or not the dice ever land.
The likeliest thing a roll pays. You choose the coral form when you spend it, and charges stack.
Won, never bought. One of each per world, kept forever, and never the same one twice.
Roughly a quarter as likely as a companion. A piece can wear this and the Crown at once.
The rarest thing a roll pays, at about a fifth the odds of a companion.
Nine to find. More each season.
A stone golem, a mammoth, a sea turtle, Pepe, a wizard, an ape, a laser-eyed bull, a CryptoPunk, a phoenix. Each one generative, each one rendered from Bitcoin, each one roaming your archipelago with its own moves.
Mossy, crystal or runic. Hewn from your biome's stone and lit in its glow.
Russet, chocolate, ginger or frost coat. Frost mammoths wear a dusting of snow.
Loggerhead, green or hawksbill shell. The one companion that swims.
Gold Rare Pepe 8%. Chill, smug or wide-eyed, in the blue tee, another color, or shirtless.
Blue, indigo, violet, purple or crimson robes. Stern or kindly. The staff glows in your biome's light.
Brown, dark, golden, silverback or slate coat. Bored, grinning or angry. Gold chain on every one.
Black, brown, red or charcoal hide. Gold nose ring 50%.
Four skins, a mohawk in any color and a VR headset glowing its complement. Cigarette 40%.
Blazes red-orange, or a rare azure flame 15%. In the legendary Aureate biome, every phoenix burns gold.
Seasonal species are winnable only while their season runs.
The board resets every fortnight.
One Bitcoin difficulty epoch per season. Seasons score height moved, not lifetime total, so whoever spent most last time starts level with you.
12 biomes. 2,100 worlds. No repeats.
FAQ
How many pieces are there?
2,100 worlds. The mint ran on Ethereum through OpenSea's SeaDrop in October 2026 and is closed, so the collection is final at 2,100. Pieces trade on the secondary market.
What do I need in order to play?
A piece, an Ethereum wallet on mainnet, and enough ETH for gas. Everything you do to a piece happens at evolve. Pieces are on the OpenSea collection page.
Can more pieces ever be made?
No. Supply was fixed at what the mint actually sold, 2,100, rather than padded out to the cap. Worlds nobody claimed are never minted afterwards.
When does my piece reveal?
After the mint closes. We then commit to a future Ethereum block, and that block's hash draws the offset that maps every token to its world. Until it lands, every piece shows the same sealed placeholder, so nothing about your world is readable early.
Can I do anything to my piece before the reveal?
Our UI keeps these closed until your world is assigned. Nothing is lost by waiting, and your piece is growing height the whole time regardless.
Can I sell around the reveal?
Yes. Your piece trades normally the whole way through, including across the reveal itself. Nothing freezes and no window closes on you. One thing worth knowing: a listing you set before the reveal stays live at that price after it, so if you would want more for the world you turn out to have, take the listing down before the reveal lands.
What is fixed, and what keeps changing?
Written at mint and never changed: biome, monolith shape, native species, terrain, sky, secret object, rarity tier, visage and optical treatment. Yours to change: height, growths and coral forms, attuned hue, companions, and the transfer count each sale leaves behind. Height matters most: it is the only number you are ranked on and the only thing you can spend.
Where does the artwork actually live?
The renderer is inscribed on Bitcoin as a recursive Ordinal, and every trait resolves from the Ethereum contract when the piece is read. Opening a token loads the world straight from Bitcoin with its current on-chain state. There is no server in the render path and no off-chain metadata.
Why does the thumbnail look different from the live piece?
The card is a still, pinned to a growth step so it stays stable wherever it is cached. Open the piece and you get the live world, which ages in real time against Bitcoin block height and shifts with weather and the day-night cycle.
What does it cost to change a piece?
Attuning the hue is an ordinary transaction from your own wallet: Ethereum gas, plus any small fee set on the contract, shown before you confirm. Growth and companions are not for sale at all. The only way to get them is to orbit.
How do I get companions?
You win them by orbiting. There is no purchase path and no holdings requirement, so no companion is locked behind owning a certain number of pieces and a set can still be completed by someone who arrives in month nine. What the odds do track is the height an orbit consumes: a large orbit is a real chance, a solo one is a long shot. Seasonal species are the exception, winnable only while their season is open and kept forever once won. One of each per world, and a companion roams your archipelago for good.
What happens when I put a piece into orbit?
It stays in your wallet but cannot be transferred until the orbit ends. Its height pours into the Core, so the Core grows taller and the donor gets shorter. That is the cost, and it is meant to be felt: you are spending something real to climb. A piece can never be poured below its floor, and every orbit ends in a roll for companions, growth charges and the rarest marks. One caution: a marketplace listing stays live while a piece orbits and becomes buyable at its old price the moment the lock ends, so cancel the listing before you orbit.
