On-chain Black Holes V1

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. Black Holes V1 can be migrated to Black Holes V2 which have improved visuals and more rewarding upgrade tiers. There is no roadmap, only the void. https://onchainblackholes.com V2: https://opensea.io/collection/onchain-blackholes
