SuperRare

SuperRare uses Ethereum blockchain smart contracts to record and verify the provenance and ownership history of every digital artwork listed on its marketplace, providing collectors with a tamper-proof authentication record.

Each artwork minted on SuperRare is tokenized on the Ethereum blockchain, embedding permanent metadata on-chain that tracks ownership history and verifies the piece's origin. The platform's co-founder John Crain described this combination of provenance and AI-created art as enabling authentication of 'nearly any piece of art.' This is a blockchain automation function rather than a machine learning AI system, but it intersects with discussions of AI art authentication. Sources do not confirm SuperRare uses machine learning algorithms specifically for authenticity classification; the authentication mechanism is blockchain-based smart contracts.

SuperRare offers a marketplace where AI-generated digital artworks, including those created by autonomous AI systems such as Botto, are listed and auctioned alongside human-made works. The platform's CEO has publicly stated that SuperRare artists were among the early adopters of AI.

Botto, described as a 'decentralized autonomous artist,' uses AI image-generation models including Stable Diffusion and Kandinsky AI to produce text-prompt-driven images. Its closed-loop engine creates up to 70,000 images per day, of which 350 are presented each week to a community of voters; the community selects one winning piece, which is minted as an NFT and auctioned on SuperRare. In 2025, Botto's weekly auctions on SuperRare fetched bids ranging from 1 to 100 Ether per piece. SuperRare CEO John Crain noted in a 2024 interview that combining art and AI creates a 'pristine provenance record' for authentication.
