Black Holes is a fully on-chain NFT collection which features procedurally generated pixel art black holes. Each Black Hole has an associated mass which changes its appearance.

This is the final Black Holes contract which contains migrated Black Holes from Black Holes V1. It improves the rendering algorithm and lowers the upgrade mass for Stellar and Supermassive Black Holes.

There is no roadmap, only the void.
