How it works
Three steps from a folder of PNGs to a finished collection ZIP.
1. Stack your layers
Background, body, eyes, mouth — drag in PNGs, reorder, name them.
2. Tune rarity
Set a weight per trait. Add a 'none' slot when a layer should sometimes be empty.
3. Export the ZIP
Get flattened images plus ERC-721 metadata files, ready to pin.
Deterministic rarity
Weighted sampling with DNA-hash dedupe so no two tokens share the same trait combination.
ERC-721 metadata
Standard JSON per token: name, description, image URI, and an attributes array.
Local-first, private
Your artwork never leaves your machine. Generation runs on the canvas in your browser.
