STORAGE

PixelChain stores each artwork's pixel bytes and colour palette in contract storage (SSTORE) at mint, readable with retrieve(). The contract has no renderer: tokenURI() points at an off-chain server, and the image is produced by the team's off-chain decoder.

A third-party developer later published a separate PixelChainDecoder contract (May 2023), which the original contract does not reference. It reads the stored pixel bytes and palette with retrieve() and draws the piece as an SVG on chain through generatePixelChainImage().
