PIXEL20-second read
Wallets in. Art out.
Your address is the seed. More wallets, bigger picture. Mint the set and it's yours on-chain, once, forever.
1 WALLET
Seed6×6 · 36 pixels
Connect one wallet. Its hash picks the palette and fills the pixels. Same wallet, same seed, every time.
2 WALLETS
Sprite36×36 · a creature
Two wallets hatch a symmetric creature with eyes, shading and markings. Order doesn't matter.
3 WALLETS
Masterpiece216×216 · a world
Three wallets paint sky, mountains, forests and a lake. Day or night is decided by the hash.
The rules
Six things that never change.
=
Same wallets, same art. Forever.Nothing is random and nothing is stored. Anyone can reproduce your picture, nobody can fake it.
↔
Order doesn't matter.Wallets are sorted before hashing. A + B paints exactly what B + A paints.
1
One set, one NFT, ever.The token ID is the hash of the set. Once a set is minted, that picture is taken.
✓
Every wallet in the set signs.You can only mint pictures of wallets you control. A signature costs nothing.
0
Free mint, gas only.Mint price is zero. Gas on Robinhood Chain is a fraction of a cent.
+
Add a wallet, change everything.A new wallet doesn't add detail to the old picture. It paints a completely new one at the next size.
