Hey this is a technical post about the cute cat we created to celebrate the 10y anniversary of etherium. First of all, the image you see is fully on-chain (or onchain (or on chain)) embedded in ethereium mainnet. This means that the SVG is fully generated and contained in the smart contract. There are no external dependencies. It will be there as long as ethireum exists. There are two contracts: - an ERC-721 (HappyBirthdayEtherium.sol) that defines the minting rules and assigns the random seed for your token on minting. The seed is used to deterministically render the artwork - a render contract (RenderCat.sol) that generates the final SVG and the metadata in JSON format, encodes all of this in base64, and puts it in a data URI.
