Per Bitfauna

Pixel data compressed into 400 bytes, stored via SSTORE2. Each 2-bit pixel pair encodes two pixels in a single byte โ€” maximum density, minimum gas.

Per Canvas

A 40ร—40 grid where 2 bits represent one pixel. Four possible values: White, Gray, Blue, Black. Every composition unique by seed.

Four shades. Two bits. Blue is the rarest โ€” the Spark that defines each composition's soul.

Normies & Bitfauna

Normies and Bitfauna share the same groundbreaking on-chain pixel art technology โ€” the 40ร—40 bitmaps fully stored in the smart contract, canvas editor, and burn-to-edit mechanics with Action Points. Yet they pursue distinctly different goals. Think of Normies as the big brother of the Bitfauna NFTs: the pioneering collection that laid the technological foundation upon which Bitfauna was built.

Normies, with its 10,000 monochrome human portraits, is the classic, highly scalable PFP collection: instantly recognizable faces, strong community, and perfectly suited as profile pictures.

Bitfauna, in contrast, limits itself to only 1,111 pieces and deliberately shifts the focus away from PFP toward pure art: the pareidolia effect in its pixel art takes center stage, the underlying technology behind Normies is taken further, and the smaller, more exclusive collection invites deeper interaction with the canvas and the pixel art itself.
