What is this?

HyperField is a living 3D ecosystem where every mushroom is a unique NFT grown on-chain. Each specimen is procedurally generated from a cryptographic seed — cap shape, gills, color, noise level, and traits are all derived from that single number. No two mushrooms are identical.

The field is a simulation: specimens mutate, wither, crossbreed, and release spores into the mycelial network connecting them all.

How to play

Connect MetaMask on Base Sepolia testnet (free test ETH from any faucet)
Buy Mycelium Credits to summon mushrooms onto the field
Choose tier — Base, Rare, or Legendary — rarity governs size, color complexity, and traits
Click any mushroom to inspect it, list for sale, or begin a breeding session
Select two of your mushrooms to crossbreed — the hybrid seed is derived from both parents
Watch for rare events: spore storms amplify particle clouds, mutations rebuild a mushroom's geometry, spontaneous withering thins the oldest base specimens
