ACCRETION

A monolith carved into Bitcoin. A reef you cultivate on Ethereum. One artwork, grown across two chains.

Bitcoin remembers. Ethereum acts. The piece is both.

01 It Evolves

No two moments of the same piece are the same.

The piece never holds still. Bitcoin's blocks age and weather it; each Ethereum action rewrites it. The art reads its own history and redraws.

The monolith ages and the sky shifts as a new Bitcoin block lands

Age & Weather

Bitcoin

The stone climbs and cracks with block height, gathers moss, and never stops accreting. Older pieces are visibly ancient.

ii

The Breath

Bitcoin

A band of light rises through the monolith once per Bitcoin block. The sea grows choppy when mempool fees spike.

iii

Tend

Ethereum

Cultivate a new growth and choose its form. Seven coral species, from native branch and fan to cultivated brain, frond, anemone and plate.

iv

Attune & Kindle

Ethereum

Shift the reef's hue to any colour, or kindle a beacon at the summit that burns bright, then fades to a permanent ember.

v

Summon Creatures

Ethereum

Populate your world with on-chain companions, a stone golem, a mammoth, a laser-eyed bull, Pepe, an ape, a CryptoPunk, a wizard. Each summon is an Ethereum transaction; the creature renders from Bitcoin.

vi

Impact Craters

Ethereum

Every change of owner strikes the stone like a meteor. A piece wears its lineage as scars you can count.

vii

Explore On Foot

Both

Every piece is a place. Drop into first person and walk its archipelago of blocky ruins beneath the monolith.

02 The Thesis

One artwork, kept on the two chains it needs. Bitcoin to remember it, Ethereum to let it live.

The Stone

Bitcoin

Storage · Permanence

The renderer and every pixel of the art are inscribed as Ordinals, directly on Bitcoin. No AWS bucket, no IPFS pin to lapse, no studio to keep the lights on. The monolith grows taller and weathers with Bitcoin block age, and breathes once per block. It cannot be switched off.

  • Art + engine inscribed on-chain, forever
  • Grows and erodes with real block height
  • Roughens its seas under mempool fee pressure
The Reef

Ethereum

Execution · Liquidity

Ownership, trading and every living trait run on Ethereum. You tend the reef and choose what grows, attune its colour, kindle a beacon at the summit. Each transfer carves a crater into the stone. The contract passes that state to the art as it changes.

  • Holder actions mutate the piece on-chain
  • Transfers leave a permanent, visible history
  • Live traits, filterable on any marketplace
Ethereum taught art how to live on-chain. ACCRETION brings Bitcoin's permanence along.
The renderer lives on Bitcoin, so there is no server to lose and no link to rot. The life lives on Ethereum, where owning, trading, and changing a piece belong. Each chain doing the one thing it is best at.
03 Nine Biomes

Each piece rolls a world from its mint.

Biome, monolith shape, native coral, terrain, sky and rarity tier are fixed the moment you mint, drawn from the seed and written into the contract. Some outcomes are far rarer than others.

Nine biomes, five monolith silhouettes, seven coral species, and a rarity tier. Combined, no two mints land in the same world.

Freshly rolled pieces. Every mint draws a different world.

04 Summon Creatures

Populate your world with on-chain companions.

Beyond growing the reef, holders summon creatures into their world, each added by an Ethereum transaction and rendered from Bitcoin. Landmark beasts and crypto-native icons alike roam the archipelago beneath the monolith.

Eight companions: Golem, Mammoth, Sea Turtle, Pepe, Laser Bull, CryptoPunk, Ape, Wizard.

Open a piece, and Bitcoin renders it.
The living artwork

Click into a token and the full interactive world loads directly from its Bitcoin inscription, fed the contract's live traits and Bitcoin block time. The renderer lives on Bitcoin, so there is no server to lose and no link to rot; the world you open is the piece exactly as it stands right now, silhouette, biome, reef, creatures and beacon included.
