What it does

The ID is the artwork
Every pattern is a pure function of its token ID. Nothing is stored and nothing is random; the same number always knits the same sweater.
Twelve palettes
Eleven standard colourways plus a rare multicolour Nordic Rainbow, which lands on roughly one token in forty.
The giant snowflake
Roughly one pattern in a hundred hides an oversized snowflake motif. Nobody has knitted one yet; it’s still out there.

How it works

  1. Minting costs 0.002 ETH on Base, and supply is uncapped; the collection grows as people knit.
  2. tokenURI points at the app rather than at stored metadata, so every token regenerates its own pattern on request.
  3. The renderer draws one element per stitch (around 50,000 of them), then rasterises to an 800×800 PNG, cached immutably at the edge so marketplaces and Frames get it immediately.
  4. It runs as a Farcaster Mini App as well as a website, with Frame support for minting straight from a cast.
