About Aliens

A51 is a fully on-chain generative pixel-art NFT collection deployed on the Base network, structured as an ERC-20 token ($A51) paired with a Uniswap v4 hook. The two components share state: when a wallet acquires a whole unit of the $A51 token through the liquidity pool, the hook deterministically generates and assigns an alien "specimen" NFT to that wallet. When a whole unit is sold back to the pool, the highest-indexed specimen held by that wallet is burned. Total supply is capped at 5,100 tokens, so the collection can contain at most 5,100 specimens at any time. Every specimen's artwork is rendered entirely from contract bytecode as on-chain SVG, with no reliance on IPFS or external storage. Each specimen is drawn from a trait system spanning eight visual categories and ten independent color rolls, producing roughly 5.9 trillion possible combinations on a 51-by-51 pixel canvas.
