HOROLOGIUM is a fully on-chain generative collection of 10,000 timepiece sigils. Every artwork is computed and drawn as SVG entirely inside the Ethereum smart contract - no servers, no IPFS, no external dependencies. As long as Ethereum exists, every HOROLOGIUM exists with it: immutable, self-contained, and impossible to take offline. Each sigil is derived deterministically from a single fixed seed and its token id, yielding a unique celestial horologe - rings, hands and ornament drawn from one shared language of time. No two are alike, and every one can be re-rendered, pixel-for-pixel, straight from the chain. Mint is sequential along a cubic bonding curve: token #0 is free, and each following mint costs marginally more - up to 0.005 ETH for the final piece, #9999. The price isn't set by a market; it's written into the curve itself. No roadmap. No promises. Just 10,000 clocks, fully on-chain, forever.
