STORAGE

PixelChain Max stores only a name, an author and a block number per token in contract storage (SSTORE). The artwork travels in the mint transaction: the compressed pixels and palette go to the chain as calldata and are emitted as an event, so reading a piece back means asking a node that keeps transaction history for that log. The standard tokenURI points at an off-chain server, and an external script is necessary to decompress the pixels and draw them.
